System write protection.
There is a mod to disable that here: http://forum.xda-developers.com/des...e-disable-write-protection-v1-0-tool-t2966850
Or use a custom ROM, those have it disabled already.

I went through all the necessary steps. Only thing/issue now is the actual flashing of the root file. It will not take. Anyone else have this issue? Is there a way to get the necessary binary or whatever it's asking for? Thank you in advance.

I have exactly the same issue

simply follow this guide -> LINK
- allow OEM unlock in the dev-settings (hit 5 times build number to see)
- allow usb debugging
- reboot to fastboot
- send "fastboot devices" command
- send "fastboot oem unlock" -> acknowledge
- send "fastboot flashing unlock" -> acknowledge
- flash the twrp image "fastboot flash recovery name_of_the_image.img"
- reboot into twrp by power of the device
- after that press vol+ up and power button (if i remember correct.. ) to get into twrp
- now u need a sd-card (micro) put no verity opt encrypt on it and magisk
- Backup all partitions u find.
- format data partition to get the size
- install magisk
- install no verity opt...
reboot
BV9600 should be rooted. Took me serveral times to get it working, because u need directly after "Flashing unlock command" to get the twrp stuff done.

First u need to go to fastboot mode, to unlock "OEM UNLOCK"
This is easy via adb
-> reboot fastboot
Did u install the correct driver? (ADB driver) is ur device listed?

i tried repacking it myself but with no luck so far, also tried various treble GSI, all booting on my BV9600Pro and basically working but mobile data and phone are broken so that's not an option for now

I don’t understand why unblock the bootloader at all if everything is installed on the MTK platform using the SP Flash Tool !?
Why these dances with adb and fastboot? if a everything is done much easier ...
You do not install the factory software using adb ? not ?? so why can't TWRP be installed and installed using the SP Flash Tool!? Why complicate things?

Root with sp Flash tool
Hi please Anyone could explain this procedure with Sp Flash Tool and post it?

Because the vendor (Blackview) locks the bootloader (like any other brand does) and does not allow installing any other recovery without it.!?

Is this a statement or a question? Sorry, I do not know English and I use a translator ..
II repeat once again, in order to install TWRP you do not need to unlock the bootloader!
it installs without problems using the SP Flash Tool
and this is not an assumption but a statement!
My first copy of the smartphone received TWRP. It was on my copy that all the first tests of TWRP and ROOT were conducted.

I'm glad to hear that it works that way to you. But that doesn't worked for me. So i wrote the way i took, to root. Let the others choose, wich way works for them. :fingers-crossed::good:

I am using another MTK device and SP FlashTool is great it lets you recover from any software brick. So I will advice people to use this method.
I am planning on buying bv9600 pro and having twrp ported and root is a good start to custom roms.
The touch driver issue on twrp should be easily solved with the good kernel module for the twrp. And official twrp support would be nice.
Subscribed to the thread will see where it goes.

hi guys, can you share a clean system twrp backup of bv9600? because my USB is damaged and i can not use sp flash tool to clean restore. thanks!

Hi, i try to root my bv9600 pro, but all i end up is on reboot the system restores to factory no TWRP or anything on it. I connected it to MTKdroidtools and it complains about a file /system/recovery-from-boot.p which restores recovery and obviously after it the system too.
Thanks for any help
edit: LOL nevermind, working fine now, don't know what was going wrong, in a last try just downloaded the latest stable magisk again. Thanks AMDFenics for the howto
Just one thing, can i get rid of this 5 sec. warning that the mobile is unlocked?

How to root?

Hi everyone
My phone model is xt2075-3,I want to root
Can I directly flash the latest magisk(20.4) to get root permission after unlocking BL?

I've succeeded in getting root.The steps are as follows
1.Download the twrp for your mobile phone,and magisk20.4.zip,magisk 7.5.1.apk
2.Visit Motorola official unlock website to unlock BL
3.You have 2 choice,A.boot on twrp one time;B.flash twrp;I choose A
4.Whatever your choose,in the twrp,install magisk zip,after done,reboot system
Enjoy root!

If you use the Magisk Manager to patch the boot image manually, and then flash that through fastboot - will that work also?
(My phone has yet to arrive so can't test this just yet...)

Update : i got the 8gb ram 128gb varient and i could boot into twrp from fastboot but i cannot flash replacing stock recovery nor i can see the internal or external memory due to decryption error
However, i basically unlocked boot loader and booted in fast boot then i flashed the patched boot.img ( installed magisk apk and added the stock boot.img inside the phone to patch it) then copy it back to pc and flashed it in fastboot mode and now i got root access
NOTE : if you happen to do something wrong you cannot use rescue and backup software to restore your phone to stock again ... flash stock boot.img in fastboot first so the software will recognize the phone back again

Get the full stock image by downloading rescue and smart assistant app from lenovo which supports moto phones ... Do login and get the fastboot rescue option while plugging your phone in the pc in fastboot mode .. then it will download it full firmware for your varient
Becareful that continue to flash the firmware will wipe your phone completely
After that get a copy of the boot.img file ... Copy it to the internal memory and install magisk manager apk from its official github site ... Now patch the boot.img you copied in your phone inside the magisk app then copy it back to your pc
Lear how to flash it from fastboot
Flash it
Done .. you are now rooted by patched boot.img with stock recovery !

I think the flash method fails because there is no partition called "recovery" - as an A/B device it looks like there are two:
Code:
nairo:/ $ ls -l /dev/block/by-name/ | grep recovery
lrwxrwxrwx 1 root root 16 1970-05-20 07:34 recovery_a -> /dev/block/sdd20
lrwxrwxrwx 1 root root 16 1970-05-20 07:34 recovery_b -> /dev/block/sdf20
if you have the Magisk zip file on the internal storage you can use the "fastboot boot twrp.img" method to flash it from there (for some reason TWRP can't see the SD card on my device)

Now for my question... my rooted (UK Retail) device has indicated that there is an OTA update:
I've tried using the method described here to restore the boot partition to stock so that it doesn't interfere with the process, but it fails (see attached images).
Does anyone know of a working method? I have downloaded the full (2+GB) update so am prepared to flash that (and restore everything else from backups) if necessary - but would rather not if it can be avoided...

Hi @xth88312 ,
can you give the link you used to download TWRP for Moto XT2075-3?

I unlocked my phone through the official Motorola site:
Unlocking the Bootloader | Motorola Support US
Visit the customer support page to view user guides, FAQs, bluetooth pairing, software downloads, drivers, tutorials and to get repair and contact us information.
motorola-global-portal.custhelp.com
I downloaded the latest Magisk and MagiskManager in the same directory from
Releases · topjohnwu/Magisk
The Magic Mask for Android. Contribute to topjohnwu/Magisk development by creating an account on GitHub.
github.com
I downloaded the original firmware from https://mirrors.lolinet.com/ and extracted the boot.img in the same directory, then issued, through the ADB connection:
Code:
adb install ./MagiskManager-*.apk
adb push ./boot.img /sdcard/Download/
(Replace the star as needed)
I opened MagiskManager app (you need to be connected to the Internet) and in the Magisk card I tapped Install > "Select and Patch a File". I browsed for and selected /sdcard/Download/boot.img and tapped "Let's go". A patched image /sdcard/Download/magisk_patched_*.img is created. Then, through the ADB connection, I issued:
Code:
adb pull /sdcard/Download/magisk_patched_*.img
adb reboot bootloader
fastboot devices
fastboot flash boot magisk_patched_*.img
fastboot reboot
At reboot, the phone was rooted.

Installing TWRP on G4 H815 doesn't work

Hello forum,
I wanted to breathe new life into my old G4 H815, but I didn't come very far, because some commands behave not as expected. Here are the facts:
1.
Bash:
adb reboot bootloader
always works and sets up the device in fastboot mode.
2.
Bash:
fastboot devices
recognises the device.
3.
Bash:
fastboot flash recovery twrp.img
gives positive feedback, though it seems not to work properly, because when it restarts afterwards and asks me if it should wipe all data it wipes the data and doesn't start TWRP.
4.
Bash:
fastboot boot twrp.img
doesn't reboot into recovery mode.
5. I used
Bash:
fastboot getvar all
to make sure that the device is unlocked.
6.
Bash:
adb reboot recovery
takes the phone to recovery mode, but then it stops with a "no command" message and an image with a red triangle and a dead Android robot appears. I pushed all possible button combination, but I couldn't enter the recovery menu.
The phone doesn't have any hardware issues and is basically in a good condition. How can I pinpoint the error?

Try removing the stock recovery before flashing TWRP. Use fastboot erase recovery
Make sure to have a backup for stock recovery should you need to flash it ever again.
Or after flashing TWRP disconnect from PC and use button combination to boot to recovery.

Thanks, but how can I backup the stock recovery? The recovery is located in the /dev directory:
Bash:
lrwxrwxrwx 1 root root 21 2015-01-01 01:00 recovery -> /dev/block/mmcblk0p39
I tried to copy the recovery to the SD card:
Bash:
cat /dev/block/mmcblk0p39 > /sdcard/recovery.img
However, it didn't work, because I get a "Permission denied" error. Maybe i have to root the phone first?

Make a nandroid backup of all your partitions with TWRP, and it should include recovery img as well. Use fastboot boot twrp.img then do a nandroid backup.
However on some phones TWRP can't backup the recovery properly, and if that's the case then do the following:
Root your phone (Flash magisk or supersu, whatever works for you)
Reboot your phone to recovery.
Type adb shell su then dd if=/dev/block/mmcblk0p39 of=/sdcard/recovery.img
This will put recovery.img on your SD card.
I'm not sure if TWRP can properly backup recovery on your device, but trying both methods won't hurt.

How can I root my phone with Magisk without installing TWRP before?
I found the stock roms for my G4 here:
Codefire - Listing of H815
How can I find out which version (10C, 20D...) I need? The recovery is contained in the stocks roms, correct?

The recovery is usually contained in the stock ROM, downloading it to make sure won't hurt.
To find the device's model simply see your device manual.
Or if you remove your device's cover it should be written on the battery.

My device is a H815 with Android 7.0 and software version V29a-EUR-XX. In order to root the phone I would like to install an image file with a rom that is already rooted, but I couldn't find an image with my software version:

How about installing magisk manager on your phone then patching the boot.img through the app?
Installing a different version than your device can cause soft brick and that if you're lucky, so don't even think about it.

I installed Magisk Manager and followed method 2 in this guide:

In this comprehensive guide, we will show you how to install Magisk Universal Systemless Interface to root Android devices. There are two different methods to install it – First…

However, I don't know where I could find the correct stock boot image for my device. I can't extract it from my own device, because I need root permissions for that.

I'm sorry, but I can't help you with that :/
Keep searching I got those sites here, here, here and here. Just from typing "H815 stock rom" into google.
I don't know if they're official stock ROM nor if they're tampered with. So use them on your own risk.
Also those sites don't provide MD5 checksum to verify the integrity of the files so I wouldn't recommend them.
If you know someone with the same device from the same vendor in the same region as you then you may ask him to backup his stock ROM for you.
You can try asking a service center, I doubt they'll readily give you the ROM though.
If you absolutely need a custom ROM or root access for some reason, then get a device that has an active developing community. On a side note don't even think about Xiaomi devices. Maybe OnePlus or Pixel.
Goodluck.

I found the matching LG-H815_Official_v29A rom which contains the following files:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Is boot.bin the file which can be easily renamed as boot.img so that Idon't need any kind of extractor tool? In the case that the stock rom wasn't unlocked could the patched boot.img re-lock the phone?

If you already found the stock ROM of your device then you don't need to root to backup your recovery.
I guess you failed to notice the recovery.bin file there haha. Don't be so tense when flashing the ROM friend relax a little and take a breath.
Now just make sure to flash the correct TWRP version of your device.
Goodluck.

[Simple method] Root N10 5G using Magisk for factory stock

First, as you might now, I am not liable if your phone would be bricked or damaged after this tutorial.
This method has worked perfectly for on my phone, which: OnePlus Nord N10 5G from Metro by T-Mobile. Build Number: 11.0.1.BE88CF. And it should work any rom stock
This tutorial is inspired by andreas__ from this topic. I recommend to take a quick glance before processing here.
General Info:
You need adb and fastboot installed and should know how to use it
You must do this process only once, afterwards you can follow the OTA survival steps
You need to factory hard reset the phone (very important)
Unlock the bootloader
If you are using locked metro by T-Mobile phone, make sure to request the "unlock token" in order to unlock the bootloader.
Google "How to Unlock Bootloader on OnePlus Phones | Unlocked and T-Mobile Variants" for the instructions
After you have unlocked the bootloader using this command:
Code:
fastboot oem unlock
The data will be wiped and it will do the factory reset
Create the boot image:
You need to pull out a clean boot image from your phone. I have used TWRP to do that
flash the latest twrp for this phone:
[TWRP][3.5.2_10][Billie]TWRP for Oneplus Nord N10 5G [BETA]
Use this command to flash it:
Code:
fastboot flash recovery Twrp_3.5.2-10_EduardoA3677-billie_OxygenOs11_Android11.img
boot the phone to twrp recovery, then head to:
Backup > select "Boot (96MB)" > Swipe to Backup
The boot image will be generated in the internal storage under the name "boot.emmc.win"
root and patch the image:
Restart the phone to the system, then download the latest magisk app
Make sure to allow "USB debugging" from the developer Options
Install and open the magisk app then tap on "install" (very top)
tap on "select and patch a file"
select "boot.emmc.win" which is the image that was generated by twrp
Magisk will patch it and place it in the download folder under the name "magisk_patched-23000_Obpf5.img"
Copy the patched image into ADB folder in your PC
flash the patched image:
Reboot the phone into bootloader mode
Then flash the patched image:
Code:
fastboot flash boot magisk_patched-23000_Obpf5.img
Reboot the phone into the system
Hurray! your phone now is officially rooted. You're welcome
I hope you find my instructions useful.

Hate to tell you this but if using twrp just rename magisk apk to magisk zip and install zip it auto patches to the right slot for you and you just confirm the install via magisk in android

Exactly.

I lost root after the forced OTA on July 31/August 1. Today I followed this guide to install twrp, factory reset, then installed Magisk by renaming the APK and flashing within TWRP. However the SafetyNet check showed "Attestation Failed." I enabled MagiskHide and rebooted, and now pass SafetyNet.
Thank you for this very simple and useful guide. I was able to root with no loss of userdata, saving a lot of time that would otherwise go into creating a backup.

Why it wait forever for attached device, even removing and reconnecting phone?

You have to be in fastboot mode before you can flash the recovery. Reboot into fastboot by typing "adb reboot fastboot" (without the quotes). Your phone should then reboot into fastboot mode. NOW, assuming you have already unlocked your bootloader, you can flash the recovery.

If anyone is still having the OEM unlocking greyed out issue, you need to do the device unlock from your phone, select request permanent unlocks then your device will reboot, from there you can then head back into dev options and you will be able to OEM unlock. Hope this helps seems not a lot of people realize this I hunted for the answer all over only to happen upon it when I was about to say forget it.

Just to add to this.....If you are unable to use device unlock because you have not met your carrier's requirements to do so yet you can use the script at this thread and it will open up oem unlock even if your phone is not eligible yet.

I have the N20. No twrp. Flashed a patched boot.img and lost radios. No wifi Bluetooth or sim)mobile data. Hoping that the platform is similar enough that someone could help me recover my device. Phone was sim locked, not sure if that's the issue. I forgot to run the command from the debloat script after flashing the unlock token, shouldn't have rushed this. I don't have a backup of anything though. Was trying to get root to back up everything. Factory resetting did nothing to fix the issue

LOL never does at this level, just wipes cache and user partition, but nothing of value where we play- the assumption is you (or the bad guys) can't figure out how to write to the system, boot, etc partitions. (snicker).
So the good news is if you can find the EDL image, and follow the procedure to reflash the phone... it should restore everything for you.

(To be clear @PsYk0n4uT I linked you to the N10 EDL thread, not the N20...)

Thanks. So my issue so far. I don't think there is even a stock firmware posted anywhere. Though there is a backup of another device posted. How would I go about finding the EDL files for mine? Can one be created? Or would I need to source that from OnePlus or wait on someone to do that? I actually wasn't aware that I could boot the boot omg without flashing it to test it out first
