[Guide] Unlock/Root/Update/Relock for BQ Aquaris X2 pro (zangyapro) - BQ Aquaris X Pro Guides, News, & Discussion

Introduction
I'm writing this thread to summarize useful information about the BQ Aquaris X2 pro such as:
preliminary actions (adb and fastboot configuration)
unlocking the bootloader
flash a factory image
root the device (currently without TWRP)
updating the device without losing root
relocking the bootloader
I own this phone since July 2018. I started writing my notes in August 2018 in the form of a Google document (link here). I shared this document with some telegram groups and some people I know.
Now I that I think it can be more useful to summarize all my notes here on XDA so that all interested people can access it.
DISCLAIMER:
By attempting any of the processes listed in this thread you accept full responsibility for your actions. I have no responsibility about your actions.
1) Preliminary actions
1.1) Developer options, USB debugging and Unlock OEM
The first thing you need to do is to enable Developer options, USB debugging and Unlock OEM. Hence:
enable “Developer options” by hitting 7 times on the build number (Got to settings --> about phone)
enter the new menu “Developer options” and,
enable “USB debugging”
enable “Unlock OEM”
1.2) Download and configure abd and fastboot
All steps listed in this guide will require the use of Google Platform tools. I suggest the use of the one provided by Google here: https://developer.android.com/studio/releases/platform-tools.
Download the one for your operating system:
View attachment 4655394
Be sure that your terminal can access adb and fastboot from every position by configuring the PATH. I'm use to configure the PATH on the fly when I need it. As I said before, I work on Linux/macOS where you can set the PATH by:
opening a terminal and running:
Code:
export PATH=$PATH:path_to_platform_tools
2) Unlock the bootloader
Unlocking the booloader will wipe your phone. So backup your data first.
The good news here is that this phone can be handled like a Nexus/Pixel phone. Therefore, the procedure to unlock the bootloader is straightforward:
do all stuff at point 1.1 and 1.2
open a terminal
plug your phone to the PC
reboot into the bootloader
Code:
adb reboot bootloader
run the code:
Code:
fastboot flashing unlock
now you have to wait until your phone reboots. It takes a while, don't panic!!! When the phone is on the initial screen turn it off and reboot into the bottloader again by holing 'power + volume down'.
run the code:
Code:
fastboot flashing unlock_critical
it's done. Your bootloader is completely unlocked. Now, you only have to wait again for the reboot.
3) Flash a factory image
As you probably know, BQ releases a factory image at each update at this link factory images. Factory images are very useful to perform a very clean install. Are you experiencing some issues with your phone and none of the trick you tried solved it? If it is a software issue a clean flash with a factory image will likely remove the issue.
Keep in mind that by flashing a factory image you will wipe also the userdata partition. So backup your data first. Now let's see how to flash the factory image:
you need an unlocked bootloader (see previous sections)
download the factory image from this link
unzip the archive
open a terminal at this folder
be sure to have abd and fastboot properly configured (see previous sections)
run the script to flash all (*):
Code:
./sdm660_fastboot_all_images.sh
wait the end of the process. The phone will reboot.
(*) on Windows you have to deal with the file sdm660_fastboot_all_images.bat. I suppose it's similar but I've never done it on Windows.
4) Obtain ROOT privileges
Nowadays, the most common tool to obtain root privileges is Magisk. Many people here know very well what Magisk is and how to install it with TWRP. However, TWRP is not yet ready for BQ Aquaris X2 pro, hence, we must follow the procedure for installing it without the custom recovery.
When I wrote the document in August I find very informative this guide by @nathanchance. It's for the pixel 2XL but, as I told you before, it works perfectly also for the BQ Aquaris X2 pro (zangyapro). So here I summarize what @nathanchance already posted. All credits must go to him.
Here you have the steps:
Download the Magisk zip from the official thread and install the manager from the zip.
Grab a boot image to patch (either the one from the latest factory image or a custom kernel one) and push it to your device:
Code:
adb push <path_to_file> /sdcard/Download
Open Magisk Manager and click the Install button.
Click "Install" at the first prompt then choose "Patch Boot Image File". A file manager will pop up.
Select the boot image you want to patch and let Magisk Manager patch it.
Pull it off your device:
Code:
adb pull /sdcard/MagiskManager/patched_boot.img
Reboot into the bootloader:
Code:
adb reboot bootloader
Flash the boot image and reboot.
Code:
fastboot flash boot patched_boot.img
fastboot reboot
Open Magisk Manager and you should be rooted!
Please note that it exists also a specific thread where the author also provides the patched boot.img files for download. Hence, you can start from point 6 without patching the boot.img by yourself. Take care of selecting the right one. Here you have the thread link.
5) Update the ROM without loosing root
To the best of my knowledge, the only way to update keeping root is by using the factory images provided by BQ.
Download the factory image of the latest firmware (link)
Extract the file zip and upload the file boot.img on your phone
Code:
adb push <path_to_file> /sdcard/Download
Open Magisk Manager and click the Install button.
Click "Install" at the first prompt and then choose "Patch Boot Image File". A file manager will pop up.
Select the boot image you want to patch and let Magisk Manager patch it.
Pull it off your device:
Code:
adb pull /sdcard/MagiskManager/patched_boot.img
Place the file patched_boot.img in the folder of the BQ firmware unzipped at point 2
Make a copy of the file sdm660_fastboot_all_images (.sh in Mac/Liux and .bat on Windows).
Rename the file, I called it sdm660_fastboot_upgrade.sh
Change the following lines (this will preserve root privileges on your phone):
Code:
fastboot flash boot_a boot.img # <-- delete this line
fastboot flash boot_a patched_boot.img # <-- add this line
Delete the following line (this will prevent your data to be wiped):
Code:
fastboot flash userdata userdata.img # <-- delete this line
Run from your terminal
Code:
./sdm660_fastboot_upgrade.sh (or bat)
I think that one can also update using the OTA. This will make you lose the root privileges and therefore, you will have to repeat the procedure at section 4. I've never tested this so, if you decide to do it, you are on your own.
6) Relock the Bootloader
By relocking the bootloader you will lose all your data, hence, backup them first.
To relock the bootloader you only need the following commands:
Code:
fastboot flashing lock_critical
fastboot flashing lock
Each command will wipe your data and will reboot the phone. Be patient waiting for the reboot and do not panic.

Reserved.
(work in progress)

First: Thanks for this really nice and comprehensive thread!
I have an important addition to point:
3. Open Magisk Manager and click the Install button.
Click to expand...
Click to collapse
Install Button will only appear if the phone has internet connection (Wifi or Mobile Data)
with this I can patch the boot image successfully
But unfortunately I can not run the "sdm660_fastboot_upgrade.sh.bat" it does not recognize my device.
When checking the commands in the batch I found that my device is acting really strange, sometimes giving different errors for the same command like:
Code:
C:\Android\X2proRoot\1.7.1_WithRoot>fastboot set_active _a
error: Device does not support slots.
C:\Android\X2proRoot\1.7.1_WithRoot>fastboot set_active _a
Setting current slot to 'a'...
FAILED (remote: Invalid Slot)
finished. total time: 0.004s
C:\Android\X2proRoot\1.7.1_WithRoot>fastboot set_active _a
error: Device does not support slots.
also strange:
Code:
C:\Android\X2proRoot\1.7.1_WithRoot>fastboot flash boot patched_boot.img
target didn't report max-download-size
sending 'boot' (50749 KB)...
FAILED (remote: Requested download size is more than max allowed
)
finished. total time: 0.004s
Probably some windows crap not working or an incompatibility of the installed platform tools / drivers and the ones from BQ...

Thanks. I was not aware of this. And now I can't check this on my device because I started using GPay and I prefer to stay with no root and locked bootloader.
Maybe I will play again with the bootloader when TWRP for this device will be released. If it will

got it running!

Probably it was just that. I Installed Ubuntu 16.04 LTS in a Vmware machine and followed the tutorial (important note here: do everything in a Terminal running under root).
Short moments of panic due to boot-loop included (I flashed a defective boot image [vmware drag and drop files obviously did not copy the whole file] )
for everybody who ends in a bootloop: just keep calm, switch off phone (>10s press power button) an very quickly when it is of press power and volume down to get into flashmode again (I had to try several times)

Hey @raudidroid, when I answered to you the first time I did not read all the message or you edited it later. Only now I'm reading the issues you faced.
On Windows, what shell did you use? PowerShell?
I'm not sure about this because I banned Windows from my personal and working life several years ago, however, recently I read some posts of people having issues with PowerShell. If this is also your case next time try to use classic cmd.

Regarding this the above quote, I'm quite sure that you do not need to be super user to apply any of the procedure listed in the guide.

Since your are suggesting "... very quickly when it is of press power and volume down ... " I can imagine that you did this procedure while your phone was connected to the laptop/PC with the USB cable. In this condition, when you force the shutdown by pressing power for 10s, the phone reboots automatically. So my suggestion is to unplug it first, in this way the phone turn off without rebooting and you can comfortably enter in the bootloader with no hurry.

without root it wouldn't work, i got "no permissions (user in plugdev group; are your udev rules wrong?)"
with root everything ran smoothly

Oh! Yep, that sounds like it would have been the better way to do it
Thanks for your post and your answers.
BTW: half-OT do you know any way to get netflix running after the rooting?

Thanks for sharing.
I'm on PIE as well. Today I flashed the factory image to make a clean install.

Hello, maybe someone can be of help to my situation.
I had my phone rooted in the last firmware version (1.7.3), and I was getting notifications to update to Android 9 pie for some time, however I was waiting to have some time to spare and first backup my files and do a factory update to pie and then root.
However, last nigh without warning my phone just rebooted and updated to pie, (firmware ver 2.0.2) and I lost root obviously. However, all my files, apps, etc were intact.
So today I decided to root my phone again. I download the firmware zip from BQ's site and then used Magisk (ver. 19.2) to patch the boot.img.
I rebooted to fastboot and did "sudo fastboot flash magisk_patched.img", and rebooted but the phone got stuck in the logo screen.
Then I used method 5 of this tutorial and ran ./sdm660_fastboot_upgrade.sh (with the mentioned modifications), however it bootlooped again. Then I flashed the original boot img and my phone booted just fine again, I tried to patch the img again, did again step 4 and it bootlooped again.
Any clues on how to successfully root ? Never had any problems updating and rooting from firmware 1.4.0 to 1.7.3.
Thank you for your time

In case anyone has a similar issue:
I could unlock. I could install the recovery. But SuperSU was coming up with signature errors and wouldn't install. I discovered that this was because the recovery was being overwritten (I flashed it to the device because "fastboot boot..." was not working).
I could not get the device to flash the recovery then reboot to recovery without it going into normal boot first and rewriting the recovery so that I would not be able to install SU.
The solution I found for this was to take the back of the phone off.
Flash the recovery: fastboot flash recovery "recovery file name".img
Then just pull the battery.
Hold the volume down when you put the battery back in and launch the device still holding volume down.
Remember to release the power button once you see fox logo or you'll reboot again.
Now I installed SuperSU without a hitch and all is good.
Hope that helps anyone who is stuck.

All the list from here is a nightly build. Can you give the stable mod? I'm noob so can follow it. it is very hard for me to make it work I'm still working to install the fast boot for mac. I found this:
bash <(curl -s htps:/raw.githubusercontent.com/corbindavenport/nexus-tools/master/install.sh)
It seems to work when i check this command:
adb devices
BUT NOT SURE if this is safe.
Please provide link for recovery or rom which i can follow using your guide. There are many in the link above but which one is stable and i can use that all the of the system functioning.
Thank you in advance.

I hope this will help someone figure things out w/ what i did... LOL
Thanks ALL. Basically the post above helped to root my phone but its been hard for me and as mentioned in my previous post, I'm noob. So here is what i did after the fastboot issue and continue on even though i didn't know if the install is safe since my OS X was able to detect the device/phone as mentioned above.
1. On fastboot, i just use "fastboot devices" to verify my phone is connected. This command did not work "fastboot -i 0x2970 devices"
2. Then use, "fastboot oem unlock-go" and i waited about 20sec as the terminal returned that message and then it was confirmed unlocked. These commands did not work "fastboot oem unlock, fastboot -i 0x2970 oem unlock-go" my terminal just froze and did nothing.
3. Then i use this to check if it is unlocked "fastboot oem device-info"
4. Using the link on downloading the recovery, i just click all of upper part with the picture and found the .img file see below:
Swift
Wileyfox - crackling
Download Latest Nightly (this is .zip file)
Download Latest Nightly Recovery (this is the .img file which i used)

5. update: i did erase recovery "fastboot erase recovery"
i use two commands and both works "fastboot flash recovery cm-12.1-20160107-NIGHTLY-crackling-recovery.img"
(here is the terminal msg: target reported max download size of 268435456 bytes
sending 'recovery' (23110 KB)...
OKAY [ 0.727s]

and this "fastboot boot cm-12.1-20160107-NIGHTLY-crackling-recovery.img"
(here is the terminal msg:downloading 'boot.img'...
OKAY [ 0.727s]
booting...
OKAY [ 0.186s]
finished. total time: 0.913s)
(I LEARNED THE HARD WAY THE .img file must be IN THE SAME DIRECTORY of the fastboot - but PLEASE ASK THE EXPERTS and don't copy if i did something wrong)
6. Next should be the auto reboot that suppose to happen but it didn't. So i took " k_web9000" advice and just pull the battery off (i didn't have any choice its not doing anything... heheh).
6. To boot in Recovery - i followed this :With the device powered down, hold the Volume Down and Power buttons.
7. Next should install the SuperSU.zip file (Please make sure to use chrome since my Safari auto unzip the file and wasted so much of my time troubleshooting... i mean hours retracing my steps ...funny) Just update it and locate the sdcard and look for the .zip file
8. Then it just rebooted after the install and on the boot screen i saw 4 files that where updated.
9. Finally, i checked for the root by downloading root checker and it was verified rooted.
Now you have been noobified

Thanks for the info and link!! Awesome!
" 4. In ClockworkMod Recovery, use the physical volume buttons to move up and down. On most devices, the power button is used to confirm a menu selection, but for some devices a physical home key acts as a selector. Some devices have touch enabled ClockworkMod Recovery, in which case you may be able to swipe to, or touch, menu selections.
5. Optional (Recommended): Select backup and restore to create a backup."
In the link you gave, how did they get the clockworkmod recovery? I downloaded & installed it in the google store but it say can not use due to the device not listed. All icons are grayed and i also tried TWRP same issue.
The link also pointed to the nightly build, is there a stable release, doesn't need much update, i can use daily and without the hiccups.
Lastly, if there is no clockworkmod, how do you get it backup as recommended in the link you gave and as quoted above.
Many thanks in advance.

There is only official CM recovery and back up is not possible. Use Titaniumfor back up. You can also use twrp recovery posted in general section. Nightlies are more than stable.

Something is not right...

i was afraid of updating coz my data might be deleted but it seems the OTA update didn't delete my data. My version now is 13.0-20160127-NIGHTLY-crackling but the downside is the google play is not present anymore. i will try install the gapp again.
i don't know if i did it right, some say you need TWRP but it works just fine w/o TWRP in updating via OTA. I also try to install TWRP but i can't get it to work, so i can backup my phone. Last option is what you suggested the titanium backup.
Please let me know if i did right and the gapp if this always going to be installed again. i will be using the same gapp file and report what happen. thanks
Report:
i tried to install gapp file but i didn't use the previous gappfile since the it needs for 6.0 android and i used arm64 but gave error:70 which is the space issue via emulated option. So i go to cyangenmod recovery>apply update> from sdcard1 and "install failed - installation aborted". I can't even see the files on my sdcard. How do you now fix this?
Also can i have the right TWRP file and instruction for Wileyfox Swift PLEASE? thanks

Something went wrong! Please help
I can't to get the gapp to installed.
I wipe everything using the cm recovery and i also was able to install TWRP recovery and it does always hangs when installing the gapp -arm64-aroma (i can choose what to install). I also reinstall 12.1 and 13 but failed again when installing any gapp even in nano version (please note that i wipe everything). in my last attempt i wipe: dalvik, system, cache, data, internal storage & android secure but nothing works to install the gapp. Btw, when i wipe from the 1st time i always get this error "e: unable to find partition size for '/recovery"
PLEASE HELP

I had a few problems doing this from Ubuntu 15.10.
1. ADB did not see the device although it worked fine on my Nexus 4 showing that adb/fastboot were configured correctly. I had to go to /home/.android and create the document 'adb_usb.ini' (right click, new document) which contains the text '0x2970'.
Once this was done I had to run the following commands
adb kill-server
adb start-server
This allowed ADB to see the device but it said that it was offline.
2. I had to create the file /etc/udev/rules.d/51-android.rules (type into terminal 'sudo nano /etc/udev/rules.d/51-android.rules') and paste in the following line, save it (ctrl+x, y, enter).
SUBSYSTEM=="usb", ATTR{idVendor}=="2970", ATTR{idProduct}=="2282", MODE="0666"
sudo service udev restart
After this ADB and fastboot recognized the device and allowed me to follow the directions posted above or on the cyanogenmod wiki.
Hope that is of some use to someone!!!

Also the Cyanogen Recovery was both unpleasant to use and caused problems trying to install GApps, I had to switch to using the unofficial TWRP recovery which worked first time and is a much better interface.

Hey do we need to unlock a bootloader before installing the custom recovery on this device? Thanks.

XT1676 - Stuck in Unlocked Bootloader, after Wipe Cache(?!)

Problem: Stuck in unlocked Bootloader
Hi all,
i am stuck on bootloader and cant get out.
On my PC I have "Minimal ADB and Fastboot"(v. 1.4.2.) installed and after i open a command prompt(admin) and type
- "fastboot devices" my phone is listed as <NR> fastboot
so that works as the only positive thing i can say
- "adb reboot", *daemon not running. starting it now on port 5037*
*daemon started successfully*
error: no devices/ emulators found
- "adb reconnect", error: no devices/ emulators found
i am not into the adb commands at all, i am a dummy and i would be so glad if someone could lead me out of my problem.
Maybe a word how i got into there:
1) i installed the minimal adb and fastboot(v1.4.2.)
2) i unlocked the bootloader by doing that over the Motorola UNLOCK Bootloader site
3) then i rooted & Flash Twrp Recovery (twrp-3.1.1-0-cedric)
with "fastboot flash recovery twrp-3.1.1-0-cedric.img"
4) first time entered into twrp recovery and i did the following:
A) a factory wipe-> reboot back to recovery mode->
B) install no-verity-opt-encrypt-5.1-> reboot and let system start before i turn off phone and enter bootloader(vol down+start) again
C) after entering recovery mode again, i install Magisk-v11.6 -> reboot->
D) now everything seemed to work, the system started properly rooted.
E) but then i decided to flash once again the Magisk-v11.6 followed by wipe data/ factory reset cause i wanted to completly do the flashing all over.
(dont ask me why i did it.. i could explain and tell you my intention but well it happened anyway and brought me to where i am stuck now)
but that was on this move not all yet: i also wipe dalvik cache
so after wipedalvik/ cache , since that moment i couldnt access to my SD Card anymore as it simply didnt show up anymore.
after a restart i was my first time in an endless bootloop of that Screen with "Erasing"(, the letters sourrounded by a spectral colored circle)
i had to disconnect the phone from power . also i tried to remove the battery for a day. but it would only get me back into that bootloop and only get me out by removing the battery...
i dont know anymore what happened then when the phone now got stuck in the bootloader instead of the bootloop. But yea, now i am stuck here, appreciating any help :highfive:

...shows up but i cant get any adb commands to work tho ofc i am a dummy at it...

oh my, i just helped myself by reading my first poste here on the forum from 2016.
i made it now to start twrp by downloading the twrp_cedric_3.1.1-0 once again putting the recovery in my adb folder and type
<fastboot flash recovery twrp.img>
followed by <fastboot reboot-bootloader>
i am curious if i can get going now and if my SD card will be read and if i can get a new flash going...

now back in twrp i go first again to wipe/ factory reset.
now going to reboot, and reboot back into recovery. only gets me back to bootloader from where i can enter twrp manually now(but there is already an indication of the problem i have?)
also before the reboot, it doesnt ask me to install the twrp app anymore where i usually choose "do not install".
now i go to install the <no-verity-opt-encrypt-5.1>, flashing it successfully as it says at the end of the process but there is also some error message in the log before the ...done:
Failed to mount '/data' (invalid argument)
now i thought i should be able to boot the system again but i only get back into the bootloader...
can someone help me how to proceed correctly?
did i miss something to flash?

For failed mount data goto wipe & select format data (option on the right)
Reboot to recovery
For always going into recovery either you don't have a rom installed or read the faq section on my twrp thread as the answer is there

First of all thanks TheFixItMan, that you are behind it and your thread looks really cool and i will immediatly read and try to understand it!
For now i am stuck in the following:

You have to select recovery from the bootloader menu to enter recovery
You can also type in a terminal window whilst phone connected to pc in fastboot
fastboot erase userdata
This will erase all internal data (the same as format data in twrp)

Important Notes For Stock Rom Users
When you first start TWRP it will ask you to swipe to allow modifications - If you do this your stock rom will no longer boot unless you disable dm-verity.
This can be done either by flashing a disable dm-verity zip or by flashing SuperSu zip which will disable it for you
Click to expand...
Click to collapse
ok, stock rom didnt boot so i flashed the "no-verity-opt-encrypt-5.1" .zip
and voila, i could boot the stock again finally! yipie!
but three things i noticed:
1) the boot progress is suspicous / wrong/ stuck at a moment:
"hello" and "moto" i still see and before the letters of moto start spinning around, the screen freezes for like 2-3 seconds and the next ting i see is the red mouth and cameleon and so on
2) i tried to test camera real quick and it says camera is busy
camera unable to start. if this repeats please power off your phone and restart.
(i did already 5 restarts now and still same problem)
anyway, i wanted to install a ROM now, something like Cyanogenmod.
in this context i wonder what the Magisk-v11.6 does? Does it just give superuser permission and is it always required?
3) system only gives me option to Power Off System(no reboot possible)
and that power off and turn on always gets me first into bootloader tho i dont press vol down+start
Edit:
ok, i have here 3 issues still but it goes offtopic already. i throw a thanks first of all at TheFixItMan and then i think thread cna be closed.
I will soon try to install a ROM, like LineageOS 15.1 , and hope that my previous 3 issues will be solved in the process. . .

Cyanogenmod is now lineageos
Use the latest version of magisk to root (see official magisk thread on xda)
You can run modules to mod phone without tripping integrity or dm-verity which if false will stop apps that check if you are rooted from working
Magisk hide can hide apps from detecting you are rooted on a per app selected basis

Phone should power off normally
If it can't be started normally without going in bootloader and selecting normal startup see my faqs in twrp thread & follow guide to wiping the misc partition
Note if flashing lineageos 15.1 you will require the 64bit version of TWRP available on the lineageos thread - I did not compile this & don't support it
It also doesn't support encryption as far as I know so if you are encrypted you will need to format data & remove it else the rom will get stuck at the decryption screen

that was not exactly the problem. my problem is that either i press restart system from system or from recovery, i first get a stop at the bootloader. from there i can just toggle to START and confirm. then my system boots. its just that i first need to confirm in bootloader the Start, always!
at this point i tried now anyways from your Official TWRP For Moto G5 Cedric- Thread |||||| your solution from your faq. But yea, it obviously doesnt fit my problem cause putting the lines in cmd prompt gave me that result and boot still does a stop at bootloader.. before i can start system or recovery..
So yea, after the first codeline didnt trigger for an unknown reason for me...
i hadnt the courage to even try the second more relevant codeline!

That error means your phone is not connected to your pc
Make sure you have enabled adb debugging in phones dev settings before booting into recovery
If you type
adb devices
It will list all devices attached
Once your device is listed the commands will work

and you think that your commands fromyour solution here helps me with my issue that i can start straight to everywhere i want? Cause atm I just always have to go over the bootloader -"stop". From there i have then to manually "START" in order to start system (now: LineageOS 15.1:victory or where i have to manually toggle down to "RECOVERY MODE" and start TWRP.
Well, i would give it a try, but yea dunno what i am doing wrong here atm. i just realized that the command "adb devices" never worked for me yet, cause i got in conflict with the command fastboot adb devices which effectivly works for me. Cause before i installed lineageOS 15.1 i had to flash the twrp cedric 3.2.1-0 x64. i did that over the adb command prompt:
Code:
fastboot flash recovery twrp.img
and in that process i even let my phone restart to bootloader with
Code:
fastboot reboot bootloader
.
now i went to tab build nummer 7 times-> dev options "on" -> android debugging enabled.
when i go to bootloader now or to recovery, and connect my device, for a strange reason in command prompt "adb devices" shows that:
... i dont know why the cmd "adb devices" doesnt show my device. maybe there is a twrp setting i need to change?

Does it display a device when the phone is fully booted
If yes than the recovery you are using doesn't support adb (my official recovery does)
If no I recommend downloading the full android sdk and using the adb that comes with that (you will find it in the platform tools folder where you installed it)

Hello, thx for your support.
I linked the wrong picture. This Screeny shows the related cmd (when dev enabled, booted to recovery, connected via usb to pc and typed adb devices).

it shows the same like linked above and when in recovery mode
so no , the 64bit version of twrp cedric 3.2.1-0 prolly isnt the problem.

ok i will try that. and the command prompt i have to open from the directoryy<platform tools folder> then right?
would you deinstall minimal ADB and fastboot before installing full android sdk?

- command prompt opened at "...\android-sdk\platform-tools"
either in recovery nor in booted system nor in bootloader "adb devices" finds my phone
so the problem with the "bootstop" (have always to manually press "START" at bootloader) persists..
oh wait... i am not connected as admin! is it possible to open an admin command promp:silly:t?
so i am am reading here atm how to open command prompt in specific folder(platform-tools)
but wife is waiting for dinner so i better do that first..

i use win7 and cd'ing to the path was almost getting annoying
as screenshot shows, it still doesnt work

in my desperation i deinstalled now all adb drivers(minimal+ sdk)
ran a ccleaner and cleaned registry and reinstalled minimal adb again (btw, there was a new version by now out, 1.4.3)
so the episodes still goes on and i could figure out some new details
because i bought the same phone again for a relative who needed a phone..
in the process of setting it up correctly( thankfully xda is around ) i enabled dev options and the adb debugging
here is the result for the new phone
that shows now that executing as admin or standard user wasnt the problem. i just did it as standard user..
then i thought "hey cool, wait, i connect now my own G5 and see if i can get the phones' Nr displayed there and make sure my phone can communicate with my pc over adb( dunno if the sentence just made sense- greetz from a dummy)"
what happened is shown in this screenshot .. same picture as before! :crying:
(dont get irritated by the screeny because i used the same command prompt for
first, the new phone and
second, my "old" phone which doesnt boot properly, if you look at the command and the result
i am lost!
is it possible to reinstall a bootloader? or how come my phone doesnt communicate with the pc anymore?
and how come that effects the booting process so that i always get this "stop" at the bootloader although i pressed for a restart?
can i do any more tests that indicates what problem i have here?

[GUIDE] Root and unbrick steps for ASUS ZenPad C 7.0 (P10Z - Z170C)

Hi all! It took me a lot of time to finally being able to root this tablet. It's old, slow and practically unusable, but with some tricks it can be made much, much better. I'm going to explain what you need to do to root this tablet, and in case of brick (which happened to me many, many times) how to unbrick it. I even got to a point where I could not even boot into recovery mode, and only fastboot was working, that was scary, but I managed to get out. Every single file I will use will be bundled in a ZIP you can download, and I'll try to make sure this link stays up, because there's nothing more frustrating than wanting to make these things in the future only to find out the link is dead, along with all your hopes. Before we begin, a little disclaimer:
Code:
#You, and only you are responsible for everything that you do or happens to your tablet.
#If you screw up, I have a number of backups to help you recover, but if that's not enough don't point a finger at me.
#I will not be babysitting anybody to help restore their tablet or recover lost data.
#This process WILL wipe all of your data, do a backup before beggining.
#YOU HAVE BEEN WARNED!
1. ENABLING USB DEBUGGING
This is a very basic step, but it's needed if you want to even begin to do this. You'll need to go to "Settings -> About Phone". There, look for a line that says "Compilation Number" (or something like that) and tap it multiple times. You will see a message pop up saying "You are now a developer" (I wish it was that easy). Go back to the settings screen, you will see a new option appeared called "USB Debugging". Enable it, and make sure "Developer Options" are enabled too at the very top of the screen. Now, connect the tablet to your computer. You will see a message pop up asking for permission, tap "Always allow from this computer" and press "Allow".
That's it for this step.
2. SETTING UP ADB TOOLS AND MAKING SURE THEY WORK
Now that we have USB debugging enabled, and we have allowed our PC to access the tablet, we can begin setting up ADB. The required files are attached in the zip.
Extract the "platform-tools" folder and move it somewhere nice. Then open it, hold shift and right click in a white space and select the option "Open command window here". CMD will pop up, now type:
Code:
adb devices
It will probably say something about a server followed by a list of attached devices. If you see a serial number there, then great! ADB is working as it should. If not, make sure the tablet is connected, that USB Debugging is on, and if all else fails, try with another cable.
Now for the juicy part.
3. UNLOCKING THE BOOTLOADER
We will have to unlock the bootloader if we want to do anything here. Here's what to do. Type:
Code:
adb reboot fastboot
Wait until the tablet reboots into fastboot. Once there type:
Code:
fastboot oem unlock
fastboot oem unlock confirm
This should unlock the bootloader.
NOTE: This method of unlocking is reported to not work anymore, but I listed it anyway just in case, as it doesn't hurt to try. If this is not working for you, don't panic, it's normal, use the following code instead:
Code:
fastboot oem asus-go
fastboot oem asus-go confirm
This should work, and the bootloader should be unlocked now.
4. INSTALLING THE REQUIRED FIRMWARE
Now, your tablet may or may not have the required firmware for the procedure, but just in case we will flash one that's sure to work. If you followed along, you should be in fastboot mode right now. Type:
Code:
fastboot reboot
Your tablet should boot as normal, without any changes (unless the first bootloader unlock method worked for you, in which case it probably wiped all of your data). Now we can access ADB once again, so type:
Code:
adb reboot recovery
The tablet will reboot into recovery mode and you should see an image of wasted android with an open belly (if you don't see this it doesn't matter). You should see a list of options with blue text, you must use the volume keys to navigate this menu. If you don't see any options, press any volume key and they should appear. If instead of getting into recovery mode, the tablet just turned off, then go to the "Fixing recovery" section.
In this menu, you must select "Wipe data/factory reset". This will, obviously, wipe all of your data. Once that finishes, select the "Install update through ADB" option. Once that's done, make sure the "updated_firmware.zip" file is in the same directory as the "adb.exe" file, then type:
Code:
adb sideload updated_firmware.zip
This will install the firmware, it will take about 20 mins. Once finished, reboot the device. You may think it got bricked at this point, fear not, the first boot really takes this long (about 10 mins).
Once everything is done, the device should boot up and everything should be exactly as it was when you took it out of the box, meaning, it doesn't even remember your wifi password. Do a quick (but proper) set up and enable USB Debugging again, make sure to allow the PC again (and check the "always allow" box). Also, scroll down a bit more in the developer options section and look for one that says "Verify apps installed through USB" or something of that kind. Make sure it's unchecked. Now, we gotta install root.
5. ROOTING
The all holy root, finally here. Type this into the terminal:
Code:
adb reboot fastboot
You should be familiar with this process by now. Once in fastboot mode, type:
Code:
fastboot boot root.img
Once finished, reboot. You should boot up as a rooted user, hooray! Only one final step, we gotta give ourselves some means to control this new power, that's where the SuperSU app comes into play.
6. INSTALLING SUPERSU
Apparently, not every single SuperSU apk file works... but lucky for you, I managed to scout and bundle one that does, so use that one. Make sure the apk file is in the same folder as "adb.exe" (as with all of the previous files) and type:
Code:
adb install supersu-2-82.apk
Leave it a few mins, and you should see a "success!" message when it's finished. Open the SuperSU app and it will tell you that you need to update the binaries. Say yes to that, and when asked wether to do a "Normal" update or "TWRP" update, select normal. It should be successful and prompt you to reboot, do so.
That's about it, you now have root access in the ASUS ZenPad C 7.0.
NOTE: Every single attempt I made to make the SuperSU app a system app resulted in the app crashing and I needed to reinstall it again, do as you please.
Why would you even want to do this you might ask? Well, I personally used this to make a few tweaks with Kernel Auditor and L Speed, two apps that will let you customize the performance of the machine to its maximum... sacrificing battery of course. You can search online for the best configuration for you for these apps. With the right tweaks, it transforms from **** to usable, and you need root for all of this.
As a quick note, you might notice that the SuperSU pop up that prompts you wether to grant or deny root access to an app is delayed, that's just how life is with this machine, it's slow. As a tip, when an app is trying to acquire root access, go back to the home screen and open the SuperSU app, then go back to the app you were trying to give it access to, it should appear quicked that way. Sometimes it's so slow that the app says I don't have root, only to have the pop up appear 10 seconds later. Now... to a final chapter.
7. UNBRICKING
This would be the end of the story if nothing went wrong, you have a rooted tablet and you can now do whatever you want with it, but that's not how life is. **** happens, things can go wrong, and when they do, you better have a backup plan. I don't know how to get back your ex, but I know how you can unbrick your tablet if that should happen. Follow these steps if you want to recover this machine...
Code:
#This process will wipe all data, but you shouldn't care about that since you can't access it anyway.
So, if the tablet doesn't turn on and gets stuck at the boot up screen, what can we do? Well, let it sit at the boot up screen for a few mins, and then type in the terminal:
Code:
adb devices
If it's recognized, then type:
Code:
adb reboot recovery
If it's not recognized, press the power button and the volume down key until the tablet turns off. Once that happens, press the power button and the volume down key, when the logo appears, let go of the power button and keep the volume down key pressed, that should boot the tablet into recovery mode. If you got into recovery mode, skip to 7.2
7.1 FIXING RECOVERY MODE
Sometimes, (it happened to me), recovery mode is broken.... it just doesn't appear, no matter what you do you can't get into it. To fix this, we gotta flash it again. We gotta enter fastboot mode. One option is to boot up the device until it gets stucked and wait a few mins, then adb should be able to recognize it and you type:
Code:
adb reboot fastboot
If that's not the case, turn the tablet off and press power and volume up, that should get you to fastboot. Once there type:
Code:
fastboot devices
And the tablet should appear there, if it doesn't... well it better do. I don't really know what to do if it doesn't appear there, but there shouldn't be a reason for it not to. I guess you can try to enter fastboot once again, with the tabler connected from the beggining or something like that, let's just assume it does, and if it doesn't then I'm sorry to tell you that's homework you will have to do.
Once here, we must format the cache and the data partition, for that type the following:
Code:
fastboot format cache
fastboot format userdata
Now, we need to get the recovery files, grab them from the zip I gave you. The files in question are "recovery.bin" and "vrl.bin". We will start with vrl. Once the two formats are finished, type:
Code:
fastboot flash vrl vrl.bin
Followed by:
Code:
fastboot flash recovery recovery.bin
Once that's done, press the power button and volume down keys until the tablet turns off. Then, press them again until the logo appears, and when that happens let go of the power button, that should get you (finally) into recovery.
7.2 UNBRICKING (FOR REAL THIS TIME)
Well, now that everybody is on the same page, and we could get to recovery mode, it's time to repeat some steps really... Follow the procedure from step 4 onwards (from the part that tells you to go to recovery). So, wipe data and apply that damn zip with sideload, the tablet should work now.
That's all I have to offer guys. I'm not a developer, I'm just a guy with a bunch of free time on his hands, so I was able to gather all of this information and (most importantly) files so you can root and fix this god damn tablet. Until the next one!
FINAL NOTE: In the files I included, there's a TWRP.img file. This is the TWRP custom recovery. As far as I know, this version should work with this tablet, but I was unable to flash it and make it work. IF YOU WANT TO TRY THIS DO SO AT YOUR OWN RISK, IT'S HIGHLY PROBABLE THAT THIS WILL RESULT IN BRICKING YOUR TABLET AND BREAKING THE STOCK RECOVERY, IN WICH CASE YOU WILL NEED TO FOLLOW THE STEPS STATED IN THIS GUIDE.
I couldn't upload the files as an attachment directly... sorry.
The "updated_firmware.zip" file is added as a separate download because it's a bigger file, and I prefer to let people decide if they even want it in the first place.
updated_firmware.zip
Everything else

None of the 8 drivers from Intel or Google detect the device in fastboot mode. I tried fixing this tablet years ago and had the fastboot drivers. As far as I know I have the same ones. These all loaded with no problem, but I could never get ADB Device to detect it in fastboot mode

Make sure you enable usb debugging, no driver will work without that enabled.

Not possible. This hangs during boot up or I can enter fast boot mode. It has been like this for years. Basically a soft brick. I tried to fix this years ago as stated above, but having seen this latest post about it, I decided to try again. But this time, I cannot find a fastboot driver that shows the device as attached when I run ADB devices

Be aware that when in fastboot mode, adb devices never lists anything, you must use "fastboot devices"

Yep! That's where I was messing up. Thank you.
And the tablet is now working. Thank you very much.
One last question though. I tried to install the twrp.img file included in the pack
fastboot flash recovery TWRP.img
Here is what I got
Sending 'recovery' (26588 KB) (bootloader) Ready to receive: 0x019f7000 size of data
OKAY [ 0.741s]
Writing 'recovery' (bootloader) Flashing partition: recovery
FAILED (remote: ' Download image size is large than partition size')
fastboot: error: Command failed
How do I get around this if the image file is too large?

Yeah I never could get around it either. I never could install a custom recovery on this tablet, it just wasn't made for it. But hey, root is cool.

Work?
Still working?

Why wouldn't it? This tablet ain't gonna change. Everything should work no problem.

Hi, any custom rom for this device to make it useful ?
It is in my drawer for more than 2 years and I just do not know what with it
Also how to play with settings in root mode so I can make it faster ?

Hey folks,
I recently followed this guide and a couple of issues.
First, I had expected all my data to be gone, which is fine. But it wasn't. I seemed to have gotten all the way through without it being reformatted, and this makes me suspect I never really achieved all the goals.
One thing I should note, in recovery boot, I had to use the volume button to select a source. No big deal, but it had not worked until I guessed I needed to do that.
Oh, and another thing is I had to install the driver package, and then after, once it was rebooted into fastboot, manually guide the device manager to select from list.
It seems after complete shutdown and then a fresh bootup, my SuperSU software was gone. So, is this only a tethered root boot? Is there a completely untethered?
After rebooting again, it seems my device will not complete booting, but I will give it some more time. I may have bricked it, though I have no idea how lol. All I did was enable USB debugging again and issued the reboot command.
I know this is an old guide, and probably long forgotten by most participants, but I recently got one of these tablets online, open box but new or like new, for around $20, and I would like to get it rooted because otherwise, it is extremely sluggish and the battery drains very fast. I read online it is google play services at fault, but I do not know for sure.
Anyway, if anyone has any updated info or alternative method to achieve full root access untethered, please advise. Unless this guide is that, in which case I just need to try again. Just out of curiosity, what is the TWRP.img for?

(GUIDE) Unlocking bootloader, Rooting - from start to finish UPDATED.

Hi all,
Have looked around the guides and such on these threads for the Oneplus 8 Pro and haven't found a full comprehensive guide outlining all parts of the bootloader unlocking and root process, so thought I'd put together my experience for anyone found in the same position, this is simply what I did, i'm sure there are other guides out there which offer different methods but I can confirm that this 100% works
NOTE* This guide is intended for all OnePlus 8 devices but the boot image files are for the EU version of the Oneplus 8 Pro on the most current firmware at the time of writing please don't use these files unless you meet the pre-requisites to the guide stated below
It is possible to extract the boot IMG from any firmware using the payload extractor tool which can be found online, then change the commands to reflect the files you obtain, for the sake of clarity I'll be using 10.5.12
Hope this helps.
Pre-requisites
A European variant of the Oneplus 8 Pro: IN2023
Running the following firmware: 10.5.12 IN11BA
ADB Access to your phone
A decent amount of charge, eg: 80%
A Windows 10 based computer
The cable that came with your phone
Obtaining ADB access to your device using your computer
1. Connect your phone to your computer using the cable that you charge it with
2. Allow it to see the device, if it automatically installs the driver (which it should) then you're good to go, if not then install the driver you can obtain from the drive which will appear on screen within "This PC" (i won't detail this as it's pretty self explanatory)
3. On your phone Open settings and navigate to "About phone"
4. Click "Build number" several times (5) then enter your PIN, this will enable "Developer Options"
5. Back out, then click "System"
6. Scroll down to "Developer Options" and open it.
7. Scroll down to "USB Debugging" and turn it on (if at this point you are prompted with a dialogue box asking for authorization then please check the box and allow it, also turn on) also turn on "OEM Unlocking" in the same section and agree to any prompts.
8. On your computer Download this folder https://drive.google.com/drive/folders/1S-yNzdvOvdZzPuxhYuEuwnelzfdEd0K2?usp=sharing
This is adb and fastboot so you can talk to your phone via your PC.
9. Move it to the root of the C: drive, so it looks like this in the filepath
C:\Android
10. Navigate to the folder and perform the following:
i) Hold shift and right click an empty space within the folder
ii) Click "Open Powershell Window here" or "Open a Command prompt Windows here"
iii) A black or blue window will appear with some text
11. In the window type the following command
adb devices
press enter
If you are now prompted with an authorization dialogue on your phone, please check the box and allow it.
You should see a readout of a device followed by a code, you now have ADB access and can continue.
Unlocking the bootloader
NOTE* THIS WILL WIPE YOUR ENTIRE DEVICE, IT'S UP TO YOU IF YOU WANT TO BACK UP OR NOT. I WOULD RECOMMEND DOING SO
1. Connect your phone to your computer
2. On your computer Navigate to C:\Android
i) Hold shift and right click an empty space within the folder
ii) Click "Open Powershell Window here" or "Open a Command prompt Windows here"
iii) A black or blue window will appear with some text
3. Type the following command into the window
adb reboot bootloader
press enter
On your phone
i) Your phone will reboot and show you a screen with 3 language choices, Choose "English" then "Advanced" and finally "Reboot to fastboot" and "Reboot to fastboot"
ii) You'll see a screen appear on your phone with some text, at the top you'll see the word "START" in green, you're now in Fastboot
4. On your computer Type the following command into the window
fastboot oem unlock
press enter
NOTE* THIS IS THE PART THAT WIPES YOUR PHONE IF YOU WANT TO BACK OUT, NOW IS THE TIME TO DO SO, ONCE STARTED DO NOT DISCONNECT THE CABLE OR FORCE A SHUTDOWN FOR ANY REASON THIS COULD RESULT IN A BRICKED DEVICE
5. Your phone will warn you and go through a set of screens, please agree and move forward until the device reboots
You have just unlocked the bootloader to your phone
Once the device has booted, set it up again and then follow the steps to unlock "developer options" and "USB Debugging" once more.
Installing Magisk Manager and obtaining Root access
Before you begin, please follow these two steps to install the magisk manager
Magisk manager
i) On your computer download this folder https://drive.google.com/drive/folders/1VH_2Ql6L5580rVYvRZ5l8t7cX2XENEAG?usp=sharing and move the file inside to your internal storage on your phone, the file is called "MagiskManager-v7.5.1.apk"
ii) On your phone using a file manager navigate to where you moved the file and open it, this will install the Magisk Manager used to manage root access, open the Magisk Manager once, you'll see it does not have root access.
Rooting
1. On your computer Go here https://drive.google.com/drive/folders/189DlZH1NSMrgVF996S7y3q5_IG9RAFIr?usp=sharing and download the folder
2. Copy the file inside the folder which is called "magisk_patched.img" to C:\Android
3. Navigate to C:\Android
i) Hold shift and right click an empty space within the folder
ii) Click "Open Powershell Window here" or "Open a Command prompt Windows here"
iii) A black or blue window will appear with some text
4. Type the following into the window
adb reboot fastboot
press enter
On your phone
i) Your phone will reboot and show you a screen with 3 language choices, Choose "English" then "Advanced" and finally "Reboot to fastboot" and "Reboot to fastboot"
ii) You'll see a screen appear on your phone with some text, at the top you'll see the word "START" in green, you're now in Fastboot
On your computer
5. There are two options for rooting, the first is to boot it first, this is safer as it is not permanent and a reboot will rejoice the booted image, the second is to flash it, this is a one step option but if the image isn't right then you could end up in a bootloop so id recommend the first.
Type the following into the window
To boot:
Fastboot boot magisk_patched.img
(Your phone will reboot automatically)
To flash:
fastboot flash boot_a magisk_patched.img
press enter
then
fastboot flash boot_b magisk_patched.img
press enter
then
NOTE* THIS WILL FLASH THE PATCHED BOOT IMG TO BOTH SLOTS, THIS IS WHAT I DID, I HAVEN'T EXPLORED IF ONE SLOT IS ADEQUATE OR NOT, IT MAY BE POSSIBLE TO ONLY FLASH THE BOOT.IMG TO ONE SLOT BUT AS I HAVEN'T I CAN'T ADVISE.
6.. Once complete, type in the following command
fastboot reboot
press enter, your device will reboot
7. On your phone open up "Magisk Manager" you should now have two green ticks signifying that you now have root access.
NOTE* If you booted the image then simply click the top install option then go to install directly, this will make root permanent.
That's it, you've now unlocked your bootloader and rooted using the most current boot img at the time of writing.

If you dont have 10.5.12 installed in both slots then I dont see any reason to flash patched image to A and B..I just fastboot flash boot magisk_patched.img and that worked fine. Ive been rooted for quite awhile though

Ok so by not specifying a slot you are flashing to both afaik
I know that the way i've written this it works perfectly, if another slot is required then it can be used when the time comes.

Sorry about that, post edited.Afaik if you dont specify slot it flashes it to current slot being used. Or you could just boot twrp (not install) and flash magisk from there. That also works. Ive tried that too

Ah ok nice, and no worries, thanks for editing.
Im aware of TWRP but for the purpose of just getting rooted this has worked for me and there wasn't a fool proof place where all the guides were so i wanted to make sure everything to get rooted was in one place and was easy to understand.
I'll edit it for TWRP and maybe some other bits once i've got to use them, but for now, this is enough to get people onto Magisk ROM's at least.
Have read different things about the slots, when i didn't specify the slot, it didn't work, so i had to specify, but had no idea which slot to choose so i chose both, it then worked so didn't want to break it i kept it, hasn't broken anything.
How are you identifying which slot is actually in use?

In twrp it reads clearly. And there is a fastboot command to check witch slot you are currently on and you can change that also in fastboot but I have to admit that I cant remember those commands from the top of my head right now

Nah it's cool, perhaps there's an app which does the same. Seeing as this is a pretty integral part of the system I would imagine that there would be.
Will have a look, appreciate you helping. Couldn't find much on the subject myself. Will edit the guide to reflect it.
I haven't actually installed twrp. Not yet anyway

Me neither, just booted it couple times. Btw its safer to patch boot.img yourself rather than use pre patched image. Just because then you now what magisk version was used to patch it in first place. Wrong magisk version can cause issues

Guides the same but the files would not be.
You can use payload dumper to extract the boot.img, then patch using magisk, then extract and follow the guide.
This guide was made for the EU version of the phone, i couldn't comment further on your device and i would not recommend continuing with the files i've uploaded if you don't meet the pre-requisites.

So in order.
1 Download the full ROM for your device and region.
2 Open it in on a computer and extract the bin file called payload, it'll be about 2.4GB.
3 Then copy it to the payload dumper input folder and run the exe
4 You'll get the boot image as well as some other files, copy the boot image to your phone and patch it using magisk.
5 Then pull the output magisk patched.img to your adb folder and flash to slot A or B or both. I did both

Yeah I did as instructed and everything is good. I wish I could get rid of the bootscreen security error message though!

I was not thinking and did this on 10.5.7 global and now I'm in a boot loop; EDIT: Just restored 10.5.5 with unbrick tool and used the downgrade 10.5.7 global from here https://forum.xda-developers.com/oneplus-8-pro/how-to/oneplus-8-pro-repo-oxygen-os-builds-t4084315 --then, I made my own patched magisk from the boot.img I extracted.

Yea that annoys me too.
There will be a way I'd imagine, but you wouldn't want to get that script wrong..
Might look into getting that gone, HTC had this too as do a few devices.
Possible a precious guide for an older device may work but using it to test would be a risk..

After doing this, is it still possible to install official OS builds from OnePlus whenever a new build comes out? Either via a zip or OTA?
For instance when 10.5.13.IN11BA comes out or whatever?

How To Guide [ROOT] [FLASH STOCK]

DISCLAIMER:
Please post failures and successes. Keep it relevant, everything else to the DMs please. It makes it easier for others to Q&A. Everyone thanks you for your understanding.
***IF YOU ARE NEW BEWARE!!! BEFORE YOU CHANGE ANYTHING MAKE A BACKUP. LET THIS APPLY TO EVERYTHING. WHENEVER THE OPTION TO BACKUP IS AVAILABLE IT WOULD BE WISE TO DO SO. FAILURE TO BACKUP YOUR DEVICE WILL RESULT IN LOSS OF DATA***
ALL LINKS ALLOWED, APPROVED AND/OR UTILIZED BY XDA. SPECIAL THANKS TO ALL THE DEVS WHO CREATED THE TOOLS WITHOUT WHICH THIS WOULD NOT BE POSSIBLE. I DIDN'T BUILD ANY SOFTWARE MENTIONED IN THIS POST. IF YOU BRICK YOUR PHONE, DO NOT BLAME ME. I'M NOT TELLING YOU HOW TO DO IT, BUT NARRATING A GUIDE TO HOW I DID IT. YOU HAVE BEEN WARNED
REVVL V+ 5G TMOBILE VARIANT ANDROID 11
IT SHOULD BE NOTED THAT SOME PEOPLE ARE REPORTING LOSING WIFI AFTER ROOT, AS HAVE I. I HAVE NOT YET FIGURED OUT HOW TO FIX THIS. I'M THANKFUL FOR ANY ASSISTANCE. FLASHED STOCK BOOT_A DIDN'T FIX IT, ONLY FLASHING BACK TO STOCK ROM. ON ANOTHER IDENTICAL PHONE DIDN'T LOSE WIFI. YOUR GUESS IS AS GOOD AS MINE. LOOKING INTO IT, NO PROMISES
Without further ado, let's start at the unboxing.
1) PREP PHONE:
power on. navigate to settings>about phone and tap "build number" seven times to enable developer options.
navigate to settings>system>developer options and enable "USB Debugging" and "OEM unlock"
FIRST disconnect the device from your comp THEN power the device off.
2) DONWLOAD PYTHON & DRIVERS:
Python
BE SURE TO TICK THE BOX THAT SAYS ADD PYTHON TO PATH and install.
Download and install mediatek drivers from here:
Mediatek USB drivers
Download and install UsbDk from here:
UsbDk
Download MTK client from here:
MTK client
and extract to the desktop. Open the folder and move everything to
C:>Users>[username]>AppData>Local>Programs>Python>Python310
In the 310 directory press Alt + D to highlight your directory path and type CMD and hit enter. This opens a command prompt in the Python310 directory.
In cmd type this command without "":
"python setup.py install"
Go make a sandwich. Preferably turkey with mustard.
When you finish your sandwich, come back and type this command without "":
"python -m pip install -r requirements.txt"
Do not exit the command window.
3) BOOT INTO B ROM MODE:
This is kind of tricky when you don't know it. The screen will will be black. Sometimes, the device will not even vibrate. There's no sunbathing android, no "No Command", no fastboot, no download mode, no recovery- nothing, nada, zip, zilch, goose egg.
Make sure you unplug the device entirely from charger and pc BEFORE you power off. Now that you properly powered off, hold ONLY BOTH volume + - keys while you connect it to your PC. Try to be quick about it. DO NOT TOUCH THE POWER KEY. Continue to hold the volume keys until you know your device connected. When you hear your device connected jingle immediately let go. The screen will remain blacked out and unresponsive. It's normal.
Let's make sure we did it right. Enter the following command without ":
"python mtk e metadata,userdata,md_udc"
Disconnect and power on. If the device has been reset, then you have confirmation.
4) PREP PHONE AGAIN (STEP 1):
5) UNLOCK BOOTLOADER:
Enter the following command without ":
"python mtk da seccfg unlock"
~To relock the bootloader in the future use command "python mtk da seccfg lock". If you flash a custom recovery/ROM and want to return to stock, then you must unroot with magisk first, then flash stock ROM with SP flash tool at the end of this post~
Power on. On the splash screen you will see system type:
"Orange State
Your device is corrupted. Device has been unlocked and cannot be trusted. Press Power key to boot.
Will Reboot in 5 seconds."
This will happen each time you boot the device because your bootloader is now unlocked.
6) PREP PHONE AGAIN (STEP 1):
7) ENABLE ADB FASTBOOT COMMANDS:
Download sdk platform tools here:
sdk platform tools
Extract.
Navigate to the platform tools folder and type Alt+D to highlight directory and type CMD to open a cmd window in platform tools.
Connect device to pc and choose file transfer.
Enter the following command without ":
"adb devices"
A prompt will appear on your phone, click allow.
Enter the following command (again) without ":
"adb devices"
First you'll see a random, arbitrary number. Second time you should see your device serial number and "Authorized", "Allowed", or "Device".
Keep this cmd window open.
8) DOWNLOAD MAGISK AND PATCH BOOT IMG:
Download Magisk from here:
Magisk
Move it to your phone and install. You'll need to allow the installation from unknown sources.
Download firmware from here:
T-Mobile_REVVL_V%252B_5G.zip
Unzip and move boot_a to the downloads folder on your phone.
On your phone, open Magisk and click install and choose boot_a.
Make sure magisk_patched file is in your phone's download folder.
In your platform tools cmd window enter the following command without ":
"adb pull /sdcard/Download/magisk_patched_[numbers].img"
9) ENTER FASTBOOT MODE:
Disconnect device and power off. Hold Vol - and power to enter fastboot mode.
Connect device to PC.
10) ACHIEVE ROOT:
***NOTE: IN THIS STEP YOU MUST LOCATE THE PATCHED FILE ON YOUR PC AND COPY AS PATH. PASTE IT IN THE CMD WINDOW IN PLACE OF "[path to patched file]"***
In the platform tools cmd window enter the following command without ":
"fastboot flash boot [path to patched file]"
Now that you've achieved root, you can play around a little bit. But be careful what you go deleting if you get debloat happy like me and delete your NVRAM & wifi. Just in case you do, here's how to return to stock.
NVRAM backup. This video makes it look easy as pie. (It IS easy)
NVRAM Backup Tutorial
Now we have to bypass DA else SP flash tool will not be able to flash ROM.
Open cmd window and type the following without "":
"python -m pip install pyusb pyserial json5"
Then, update by entering the following command without "":
"python.exe -m pip install --upgrade pip"
Download LIBUSB:
LIBUSB
Run LIBUSB Win 32 filter installer and select Mediatek driver
Enter B ROM mode and connect to PC
Navigate to bypass tool and open "brom.bat"
Close cmd...
Run "flash_tool.exe" in sp flash folder
Options>options>connection tick UART
That's it. Now you can flash with sp flash without encountering error

Download OTA and use a payload dumper to extract boot and scatter. You can also get DA, but it does nothing. You must bypass DA in order to flash ROM.

[FLASH STOCK MODEM FILE]
My next guide will be how to use assurance wireless with ANY phone. I'm using assurance wireless on my Oneplus N200 (DE2118).

Hi. I read many posts of yours regarding the REVVL V+ 5G, I was encouraged by your progress, and took comfort that someone else had some of the same struggles that I did. I was able to unlock the bootloader, I was able to root the phone (using an img file posted by someone else here; I hadn't yet read your root recipe), but I was no longer able to connect to wifi. (is this familiar?) In trying to undo the mess, I ended up making my phone unbootable.
I wanted to install stock ROM from scratch. I read your instructions, but there's no scatter file in the ROM that you posted. So I'm confused.
I figured that I could install the stock ROM zip via TWRP; I googled and found a TWRP for "Sprout" (the codename of our device), but for the life of me I couldn't install it on my phone, no matter what I tried.
You're ahead of me here; perhaps you can get me on track. Right now, my phone isn't booting at all.
Thank you!

Hey, I finished the guide. You can return to stock following the guide above. As you may have noticed I edited this message instead of posting again. It's okay, cause I brought good news, right? Cheers

i totally forgot, yeah, i will look up the proper method to install twrp. it's supposed to be easy. i thought i was going to have to port twrp-and i still might- so i'm looking into it. i need to flash twrp myself. there is supposed to be a way to use rom2box or spflash or twrp or something to make a flashable zip. i don't know if that's a thing. it seems to me somebody needs to build a preinstaller that automatically flashes each img. for you. like a 1 click. if we can get twrp on this, that's the next step. to make a flashable zip. or somehow one click installer. i imagine if i did, it would only work for this phone, but could be modified for similar devices. i know tcl has a software like that. they plug a phone up and click one button. on their end it's one folder and that program does the rest. that program is what i want to write. reverse engineer this shiz and get a complete understanding of it. i know good and well the folks at tcl aren't sitting on a cmd window using adb to flash dozens of duplicate images time and time again for each device they build. it's screw it together, plug it up, click a button and test. they already have all the files preloaded and they have a preinstaller that pretty much instantly flashes the software. damn, wouldn't it sure be nice to have? but i don't foresee anybody leaking it any time soon. maybe if you have the cheese

And may I ask for a clarification, please: You wrote above, "the firmware links i sent you- there should be at least 2 different ones, and an OTA... well, if you open the root folder and type 'scatter.txt' in the search bar it will pop up." In your post, I see 2 links to firmware; one is called https://www.mediafire.com/download/sxq4cz8bddmr49l, and one is called https://www.mediafire.com/file/irigs9iviy3sobw/T-Mobile_REVVL_V%2B_5G.zip/file. I downloaded both. I clicked on the downloaded file, and in the search bar, I searched for "scatter.txt", and got no results. What am i doing wrong? Thanks

It needs to be ported still. Unless it's already ported I'm working on it now. Nightmare. I'm trying to follow a guide on here about porting TWRP... Going slow...

After installing the modified boot img with fastboot my phone bricked and i cant fix it, it just crashes on boot and loops back whenever i try to normal boot.
If there's any help you can offer I'd appreciate it.

Edited: guide complete. Try it now.

When your phone boots up do you see system font on the screen? It should prompt you to press power to boot normally, otherwise it will continue to reboot. It's because the bootloader is unlocked and you must press power to acknowledge this or else the phone will boot loop. Does this help? If not, get another phone and download magisk and try to patch boot_a again. You can use another device to do all those steps to get the file ready. Pull it, plug in your revvl v+ again and try flashing it. You can also try a different copy of the firmware, I linked 3. You can also flash stock boot_a and boot_b and that should get you going. I'm still figuring this device out. I advise you reach out to somebody who has a lot of experience flashing a/b partition scheme devices, namely mediatek. Project oppo. My only other suggestion is to flash the stock firmware using adb fastboot commands. In the forums you can find a guide to flashing a/b... So, just to be clear, recite to me exactly what you did up to the point it boot loops. And tell me is there system type on the screen when it boots?

So i Followed the guide exactly and everything seemed to work fine until i flashed the img modified by magisk. Fastboot said it moved and wrote successfully.
Then when i rebooted and hit the power button again to bypass the 'orange' warning instead of starting into a factory reset phone, it flashes the backlight and starts booting again.
Im also unable to get into recovery, fastboot mode is all that works now. I've tried to flash the stock boot_a img but not the boot_b, do you think that would help?
I'm gonna make a new img with my s9 and try that as you suggested.
Edit:
Well i might be handicapped.
I had 2 phones here, the V+ and the 6 pro.
Turns out i did youre walkthrough on the revvl 6 pro. It did unlock it, but obviously when i flashed the boot.img for the V+ it bricked. And i cant find the backup anywhere.
In short thanks for your time, I'm afraid all i did was waste it :\

Edited to remove irrelevant content. Guide complete. Try it again. If your phone will not hard reboot, try adb reboot bootloader. All activity should cease and your device should promptly enter fastboot.

I couldn't agree more. Lol. I'm actively editing the content to condense it. I'm also working on porting TWRP. I've done some other things to save a few steps, like patching boot_a and putting it on Dropbox so all you'll have to do is download it and flash it. When a13 OTA gets captured it'll get better

I am able to unlock the bootloader, then my phone just hangs at the boot screen, but I can can lock it again Now it just boots with the orange warning and it doesn't matter after that if it is locked or unlocked
The android version is still 11 with a security update from Dec 5, 2022.
I am just curious if there is a way to revert back to a previous version that might just work like the version listed for download. There could also be differences in the boot file that is in the firmware zip file from what is on my phone so patching and installing a different version won't work.
Maybe just waiting until the next version is releases would be the best option?

Perhaps that. In fact, that's what I'm waiting on- the a13 update. I intend to capture the OTA and follow the spflash walkthrough. Then I can update this how to where it'll work for everybody. I have 4 people right now with boot issues after root that go beyond WiFi, and they all 4 can't get spflash to work. It's bugging the crap out of me, I haven't been able to figure out what to do to fix it. I'm still waiting on some other folks I've reached out to, if they ever have the time...
