EDIT:SOLVED -- READ BELOW:
I finally got it flashed by following a few guides here which I will link, and try to break it down easier for someone else to come across and follow. I thought I bricked my phone (flashed LineageOS then rebooted, phone did not show anything on screen, full black screen) but after following a few guides I got it solved.
If you get bricked, or just want to follow a clean perfect install, please start below (Skip to step 2 if you are starting fresh, if you have soft-bricked your device start from step 1)
1. Bricked it and had to execute QDLoader 9008 fix again.
Tutorial is easier than it looks, do not fear, if you have soft-bricked your device and see a black screen, go ahead and go through the qdloader brick solution.
2. From factory recovery updated to Version WW-16.1220.1909.193.
If you have started fresh, I would highly recommend updating to the more updated firmware first. For me this worked, and I suggest updating to get a more current kernel, which may play better with Lineage OS install. To install a newer stock firmware linked above, download the ~2GB Firmware above, and save it to your Minimal ADB / Fastboot folder. Power off your device, after it has been successfully restored (if you bricked it) or you want to start off fresh and get the install right the first time. With your device powered off, Hold Volume UP and then Hold Power Button until the Fastboot menu appears. Use your volume keys to select Recovery, then press Power button to enter the STOCK Recovery (we are still on stock firmware with stock recovery). When in stock recovery select install from ADB. We are going to push the install via ADB (I tried dragging the firmware to the internal and selecting install ZIP and that didnt work).
Go into your Minimal ADB / Fastboot folder on your computer and open command prompt by holding Shift+Control and Right clicking and then selecting open command prompt here.
Now, enter the following command in the command prompt and hit enter:
adb devices
This command will show if any fastboot device is connected. If it doesn’t show, then please check the drivers are installed properly and try again.
If your device is listed, then type the command given below and press enter:
adb sideload File_name.zip
^^This will be the ~2GB Firmware file downloaded above
Wait until the installation process completes.
Once the installation process is complete, restart your device.
Done. You have successfully upgraded the Asus ZenFone 6 to the newer firmware, please continue.
3. Downloaded OTA 16.1220.1909.193 to 16.1220.1909.194, renamed it to UL-ASUS_I01WD-ASUS-16.1220.1909.194-1.1.1-user.zip and placed into root of internal memory.
When I disconnected USB cable (or rebooted, not sure), I was prompted with update notification. I have updated it. Either way, reboot your device if you don't see the notification, and look in your notifications to see something saying: System Update Detected Proceed with Update - and select it and update.
4. Now that your phone is 100% Updated with the newest firmware, let's follow another guide I found here:
I assume you're on a fresh Android 9 stock ROM, or just finished restoring your phone with the Flashall_AFT.cmd from this tutorial.
You should at least boot once on the system, and disable any PIN or password to unlock your phone (hence putting a default password for the FBE).
Download the latest OFFICIAL TWRP.x.x.img (which we'll use to boot on it), and it's installer to install it later (TWRP.x.x.zip) if you want to use it.
LineageOS installation steps :
Reboot to bootloader (=fastboot mode), connect to your PC and boot on TWRP :
Command:
fastboot boot TWRP.x.x.img
Once on TWRP, you can see that we're on slot A (Menu > Reboot). Now go to wipe > factory reset and then wipe system (technically I suspect this only wipes slot A, but do it anyway, don't worry about the errors!)
Now go to Install > flash the newest official LOS_latest.zip. What happens here is that the LOS installer will flash LOS on the inactive slot (slot B in our case). And will also install the LOS recovery (on both slots it seems).
Reboot to recovery : your phone automatically switches slots and will boot the LineageOS recovery (Don't fear, we don't need TWRP right now, just go along with this step) on slot B.
On the LineageOS recovery, do factory reset (which seems to be a full /data format in fact, thus removing any previous encryption AND all your data on internal storage). If you want to use Magisk, go to the recovery's install menu and sideload it now
Use code:
adb sideload Magisk-v20.3.zip
Now reboot to system. It might take a while (one or 2 loops in my case), but your phone should boot, or in some cases will end up on LOS recovery asking for a 'factory data reset' (then do it and reboot again).
Once booted on your LOS rom, you can define a pin or password to lock your phone (that'll be the FBE decryption password).
Now if you want to use TWRP, reboot to bootloader and boot again on TWRP.img (step 1)
From TWRP > Install > flash TWRP.x.x.zip (that is, the TWRP installer). It installs on both slots by default. If you had installed Magisk, you have to flash it again (because anything modifying the boot.img - like the TWRP installer in our case - will erase it).
You can now reboot to system and enjoy LOS
Thanks for the nice documentation. I've recently also struggling with installing a custom ROM and this clears some things up.
Wanted to ask, if you also have the audio issue that 1) callers hear an echo of themselves, and 2) the bottom speaker is active when receiving a call?
Thanks.

Haven't actually put my sim in yet to make calls, will let you know later today, sorry about the delay!
I had previously attempted this a number of months ago, and managed to soft brick my Zenfone 6 several times, eventually kind of giving up and just using the stock firmware.
I tried again back on Memorial Day in the US. This time around, I bricked it hard. Could not get device to power on in any fashion. PC would not "see" USB connection at all.
I returned it to ASUS for service, and they've charged me a little over $200 to repair it. The only problem they noted was, "Device is rooted/unlock". So I have no way of knowing if their diagnosis is based on actual inspection of the device, or if they're just replacing the SOC on the basis that I used their official bootloader unlock tool, thus registering my phone's S/N.
Just a little caveat emptor for anyone attempting to use this guide. I was able to get TWRP to load, and succesfully updated the stock firmware, but any and all attempts to load the Lineage image failed.
Eventually one of them soft bricked my phone as before, and I think my mistake was interrupting the soft brick rewrite procedure by prematurely unplugging my phone from the PC.
I had a similar issue: Bricked and totally unresponsive phone (or so I thought until I realised the screen was flashing very faintly when I switched off the lights - I could only tell in the dark due to how dim the flashing on the display was) where de "Powered by Android" logo kept flashing for a millisecond and in a loop. None of the button combinations worked so I couldn't switch completely off, access recovery/fastboot, and my computer wouldn't recognise the phone when I connected it via USB. I ended up buying an EDL cable for deep flashing Qualcomm phones (€9) and within minutes I was back up and running. All solved.

I bought it from Amazon. The one I bought is out of stock now, but there are a lot of them available (from other brands/sellers). This one for example - is the one that most resembles the one I actually bought: https://www.amazon.es/ASHATA-tel%C3%A9fono-reparaci%C3%B3n-Adaptador-Engineering/dp/B086WZMFKW/ref=sr_1_18?__mk_es_ES=%C3%85M%C3%85%C5%BD%C3%95%C3%91&dchild=1&keywords=cable+edl&qid=1597417614&sr=8-18
Since the thread is already on topic, could I flash lineage os while being on a custom rom? I have Bliss ROM on partition A and stock on B. Is it possible to have both Bliss and Lineage in dual boot?
Also, maybe a little off topic, the partition A/B scheme was intended to be used as a dual OS boot like normal PCs? Because right now I can select A and boot Bliss, select B and boot stock, I don't get why the procedure for flashing Lineage OS is so convoluted(requires having stock both on B and A?!) since both partition seems to be standalone and separated from each other.

The cable itself (on its own), doesn't seem to "do" anything, but is paramount in reaching the right area, in order to fix the problem by means of the appropriate instructions and files. I can't recall where I ended up getting the right instructions from - as I researched quite a bit, and did a lot of "trial an error" before getting it right - so I'm sorry but I can't refer you directly to them via link (so that whoever posted them originally gets the credit they deserve), but this is what I ended up doing (on a WINDOWS machine) based on said instructions:
DOWNLOADS:
- Qualcomm drivers: https://androidfilehost.com/?fid=11410963190603857508
- Firmware with scripts: https://androidfilehost.com/?fid=1395089523397969054
- Latest official ASUS firmware from the ASUS webpage (download and place it in a memory card)
- (If you don't already have it on your WINDOWS machine): download and install Microsoft Visual C++ 2010 Service Pack 1 Redistributable Package
PROCEDURE:
1- Install the Qualcomm drivers
2- Unpack the downloaded firmware containing the scripts
3- Place the memory card in the phone's slot (with the latest official ASUS firmware already in it)
4- Power off the phone by VolumeDown + Power buttons (keep them pressed for about <25 seconds)
5- Connect the phone to the computer via the EDL cable and press the button on the EDL cable (there was an extra bit on what to do with a archive from the drivers file if your computer doesn't recognise the port straight away, but it wasn't necessary in my case so I didn't keep that step/archive name in my notes... I'm afraid you will have to search for it like I did if you come across that issue).
6- Start update_image_EDL.bat script from the unpacked firmware
7- After the script in step 6 finishes, start script flashall_AFT.cmd
8- Start bootloader
9- Go to stock recovery mode and install the ASUS firmware from the memory card
X- (Instructions also suggested to repeat steps 8 & 9 again at this point - for a second time - but in my case it wasn't needed)
I hope this helps.

Hey buddy, I appreciate your reply. The cable is on its way but I got a bit fiesty and opened up the phone to short the two contacts. This did the trick for me, got me back into EDL mode, and I was able to flash the latest firmware. On that topic, I'm trying to find the most suitable firmware version to run LineageOS 17 on the phone. I grabbed Mauro's TWRP to temporarily boot into which allowed me to flash the latest Asus image from their site. I guell I'll just carry on from there.

As far as I understand, that's pretty much what the cable does actually... I also came across that method along my research, but I didn't want to risk opening the phone up. Since you are in the "flashing state": be careful with some of the instructions out there - I flashed through TWRP as I have been doing all these years with other phones, following specific instructions for each ROM I've tried, and I had nothing but issues until I flashed through ADB. I still don't know why I was getting the "No OS" warning all the time despite flashing correctly from TWRP (contemplating the A/B partitions matter), but none worked...

Appreciated but I'm all sorted. I believe my pitfall was not using the copy-partitions .zip file detailed in the instructions. I had no idea that was a thing. Was extra careful this time and now I'm on the ROM I need.
I ****ing hate A/B partitioned phones, makes custom ROMs such a chore. Sort of getting fed up with phones in general but at least this is working well for now.

Same here. It was so easy to do the Samsungs "back in the day", and you always had ODIN as a fallback if things went south. But this "A/B" partition nonsense (as well as other useless changes they introduce every time they "upgrade" Android, or certain structure modifications every so often when a new phone comes out) are a pain in the butt! Changes clearly aimed at making things more annoying/difficult for us people who don't want standard/corporate/unnecessarily bloated phones... Actually (as a former Blackberry user) I was tempted to get one of these Android based Blackberrys (the KEY2), but I didn't in the end precisely due to the fact that the bootloader can't be touched, and it can be rooted...

I want to switch to because the latest security update (August 2020) by Asus is soft bricking the phone for many users,
but I am seeing a few reports about some bugs (like the phone is stuck in the lineage boot symbol and cellular errors) in lineage os and also seeing few post with a lot of installation errors (like soft and total bricking) etc. and for me in developers options I'm not seeing the OEM and advanced boot options.(in my asus stock os) I just found out that I have to download the Unlock Boot loader apk separately from asus and install it using command prompt so I don't know how to proceed.
Can you please elaborate on how you actually did it with your Asus Zenfone 6(2019), I am a total noob in this and I also couldn't understand the partition a and b parts too.

EDIT: included rough procedures for OEM unlocking, and updated link to recovery-verified.img (Sorry for uploading the wrong file ><)
Hi all bv9000 pro Users!
Recently I went on a journey to root this awesome rugged phone with one purspose: to remove that F*@(#&$ god awful loud annoying sound triggered by the OS when you use a camera app to take a picture + the boot startup sound (A bug blackview hasn't gotten around to fixing).
I successfully managed to port TWRP 3.1.1 from the Blackview bv8000 Pro and run it on the Blackview bv9000 Pro-f!
I've then managed to flash in Magisk to gain root access.
DISCLAIMER: I do not take responsibility for any bricked phones caused by the process, do so at your own risk (yadayadayada).
NOTE 1: Although I've got it running on the bv9000 Pro-F, this image should also work for the non-fullHD version, if someone can test this I'd be happy.
The link to the stock ROM (with the modified recovery img) can be found in the post below.
NOTE 2: No need to download anything other than what I've listed, Magisk is included in my custom recovery to circumvent the need to load the devices encrypted storage (or any other external storage) nothing stops you from mounting external usb storage.
What you'll need:
- USB Mouse (As there is no touchscreen input support, your device should have come with a usb-c otg cable so there's no problem here!)
- MediaTek SP Flash tools (I'd recommend the latest version) https://spflashtool.com/
- unlocked bootloader (You should be able to do this via the developer settings -> unlock OEM Bootloader)
EDIT: To unlock the boot loader, do the following:
1) Go to settings -> unlock OEM Bootloader (tick)
2) plug your device in (assuming you have ADB installed), use adb to access fastboot via. command prompt:
"adb reboot bootloader"
Then once the device is rebooted into fastboot mode
"fastboot oem unlock"
KEEP IN MIND THIS WILL REMOVE ANY FILES, so back them up
- I've done this with windows, but you should be able to repeat with linux no problems!
- A little patience
Pre-preparation:
First install any updates and back up your data (it's just easiest to use the google cloud backup as restoring becomes easy as pie, updating also fixes the setup wizard crashing on first setup). This is necessary because OTA updates cannot be performed with TWRP recovery, and flashing TWRP before doing OTA updates will flick the device into a recovery boot loop.
Install the SP Flash tools, and the MediaTek VCOM Drivers
(I won't link the specifics here, a quick google search should be able to help you, just note you might need to disable driver signature enforcement)
Two options for flashing:
1)
My Full Stock ROM already pre-prepared for flashing:
Patched ROM
No need for extra prep here! you should just be able to load the scatter
2)
My custom patched TWRP stock rom: recovery-verified.img
Blackiew's stock rom: stock rom
- Download the stock rom, backup the recovery-verified.img in the R06 folder, and then replace it with my custom patched TWRP stock rom (file name should be the same).
- Run "CheckSum_Gen.exe" once you replaced the file, it will generate the necessary checksum to allow SP flash tools to successfully flash recovery.
Once you've done with the pre-prep, switch off your device, take a deep breath and you're ready to go!
Steps!
1) Load up SP Flash Tools, select the android scatter file you've downloaded in the R06 folder
2) Select Download Only (I MEAN IT, FORMATTING WILL REMOVE YOUR IMEI AND RENDER THE PHONE USELESS)
3) Deselect everything but recovery (You only want to flash this)
4) Hit download
https://pasteboard.co/HkufwZZ.png
5) Hold volume up + power and plug in your phone, keep the volume up button held
6) very quickly the flash should be complete, and you should be greeted with a big ol' green tick to verify
https://pasteboard.co/HkuiTBB.png
7) Once you're done, remove your USB cable, plug in the OTG then we proceed to flash magisk
8) Hold power + volume up until you reach the bootloader, then use the menu to select recovery
9) You *should* be greeted with the TWRP recovery screen (Which is great success! )
DON'T PANIC IF YOU CANNOT USE THE TOUCH SCREEN, the kernel I've patched is missing this, seems the driver is different between touch screens, just plug in your OTG mouse to continue from here!
10) Use your mouse to first hit cancel, we don't need to decrypt the user data storage.
11) But oh no! it's all in Russian (no problem, Next step sorts that)
12) Use your mouse to navigate the menus as shown here to change to English! (or your preferred language) Change Language
13) Click install, then navigate up folder levels until you are in the root directory
14) scroll down and click on Magisk.zip, install it, allow it to install any apps as system apps (because this will then install to the system image, not the userdata)
15) reboot the phone (if it hasn't rebooted already)
16) You should be able to boot into your usual phones OS, if you don't see Magisk listed in your phone apps, just download it from here:
Magisk Manager
17) Congratulations! You should have complete root access :laugh::laugh::laugh:
Feel free to express your thanks, or list any problems you have, but keep in mind my studies take all my life, so I may not be able to help with all the problems you have
Congrats! Would it work on the BV9000 HD version?
Hi!
From what I've seen they both run the helio p25 chip
(Just a difference in RAM size) so it should.
You're more than welcome to try.
Just keep a backup of the original ROMs recovery. If something goes wrong during the boot to recovery you can easily re flash
hi i tried both optinos but they didn't work for me
I tried the first and the second options and it was showed me same error:
ERROR: STATUS INSUFFICIENT_BUFFER(0XC0010007)
I tried download only, format all and download, if i install original ROM its installing without problems!
In settings-> developer options -> OEM unlocking is enabled
can someone give me tips if I'm doing something wrong. thanks
My phone is Blackview BV9000PRO-F
Hello,
i have the blackview 9000 pro Hd (not full hd)
i first tried your prepared patched rom = not working (get erorrers in step 6)
then i chose step 2 and i was thinking to use the stock rom from the NOT full hd rom
now i get a green screen from the flashing: but after rebooting in recovery nothing happens, just normal reboot then
perhaps this is not so clair for me:
- Download the stock rom, backup the recovery-verified.img in the R06 folder, and then replace it with my custom patched TWRP stock rom (file name should be the same).
- Run "CheckSum_Gen.exe" once you replaced the file, it will generate the necessary checksum to allow SP flash tools to successfully flash recovery.
the file name you posted here " My custom patched TWRP stock rom: recovery-verified.img" is ramdisk-recovery.img
i replaced the ramdisk-recovery.img... it is not clair need to replace recovery-verified.img to?

Hi, you need to unlock the OEM bootloader, if this is still locked it will prevent the flashing of custom ROMS.
I might've missed this step, will update post as necessary.

I already did this step:
Enable developer options-> OEM unlocking is enabled
Is that enough for this MTK phone to be unlocked the bootloader ?
And tried the both options but the results are same.
I have been unlocking bootloaders on many phones but first time MTK phones. If i try with adb commands it recognize when is in the android with command adb devices and show my device but if I try reboot bootloader and check in device manager in windows its show its connected and drives are correct but if i try to show the devices, it doesn't show any device connected
Hi,
You need to install fastboot drivers once it's in bootloader mode,
then use fastboot, not adb.
"fastboot oem unlock"
Then follow instructions.
simply doing settings -> oem unlock won't unlock the bootloader, it allows you to do so later via. fastboot
Check the original post, I've added the extra instructions sorry about the confusion!
Thanks a lot. I finally succeeded to unlock the bootloader and root my phone and install the magisk.. I did without use your rom just I unlocked the bootloader and install your twrp file and after in the recovery mode i format the data and istall magic and i still have the last updated android.
I hope this it ill help to other people. Cheers

Congratulations .... I need a tip,.
And, brother, thank you very much. Worked perfectly.
But first I would like to get you a tip ..
One of the main reasons I have done all this complicated process was to be able to disable the crap of the loud music that plays when the device is started.

TWRP looping after OTA update
My dear, the procedure worked very well, until an OTA update was downloaded.
You are now looping on TWRP. How do I get out of this?
:crying:
help!
i missed to run wireless software update,so ROM clashed.
How can i re-install custom ROM?

Hi guys, lemme apologize for disappearing, life and whatnot!
For those stuck in a TWRP boot loop, simply restoring the original recovery then restarting the phone will be enough to fix the problem.
(Actually you really don't need TWRP after the phone is rooted, maybe I should update the guide?)
Many Thanks
First off, thank you for your hard work. Loved the "**** it we have an OTG cable let's use it" haha. It works fine for me.
Second, do you happen to know if someone has ported Oreo on our bv9000 ? Or do you know of any ETA ?
Thanks again,
Cheers
Anyone tried on the BV9000 Pro? Don't think mine is 'F' OR 'Fhd'.... I must have first model brought out...
Ugh.. Windows and Drivers?!?!
I keep getting Driver not Recognized in Windows 7 Pro X86.
I installed the latest vcom/usb drivers, in legacy also. No Go.
I installed from several other sources the drivers, including the Automatic Mediatek driver install. No Go.
So if anyone has a tip for me, please let me know because once more Windows is proving itself ridiculous. I can't even get to the storage of my phone. Did something change with a Windows Update that it's not allowed anymore?
I put my BV9000 Pro in OEM Unlock and USB Debugging. I backupped everything. My phone is ready for it. It's as ready as Amy having coitus with Sheldon for the first time.
Hello everyone, after struggling for a few hours I managed to finally disable force encryption in my phone (so that TWRP could backup the data partition).
I'd like to write a quick list of what I did in the form of a guide to unlocking the bootloader, installing TWRP and getting root with Magisk. I'm just a user, not a developer and this guide is brief, it's not a detailed tutorial and does not include trivial steps (like how to install drivers for your OS).
Warnings: Although small, there is always the chance this bricks your phone. I take no responsibilities.
This will factory reset your phone so back up everything before you start.
My phone is Lenovo S5 (K520) Global version (see screenshot) I don't know if this will work for other firmwares.
Prerequisites:
Install Phone, ADB and Fastboot drives. You can get ADB and Fastboot binaries from here:
https://forum.xda-developers.com/showthread.php?t=2588979
Download this archive:
http://www.mediafire.com/?4dcvzw1hdmzfn10
It contains all the files used in this guide.
Alternatively, download all the files used from their sources.
You will need an SD card or a USB flash drive with an OTG adapter.
Copy the following files to it:
A. "Disable_Dm-Verity_ForceEncrypt_12.16.2018.zip"
(Downloaded from http://forum.xda-developers.com/showthread.php?t=3817389 )
B. "Magisk-v18.0.zip"
(Downloaded from http://forum.xda-developers.com/showthread.php?t=3473445 )
C. (optional) "\stock\boot.img"
(Downloaded from the global firmware @ 4pda)
If you chose to use Micro SD card, you can insert it now.
Note: I know there is a way to push these files directly to TWRP from PC through USB instead of using SD Card/Flash drive but I've never tried it.
Lets start:
1. Go to 'Settings>About phone' and tap on "Lenovo version" several times until developer options are enabled.
2. Go to 'Settings>System>Developer options' and enable "OEM unlocking" (Note: for me this option was greyed out and I had to connect to wifi and wait for a minute or two).
Optional: Enable "USB debugging" if you wish to enter fastboot via ADB.
3. Turn off the phone and press and hold 'Volume down'+'Power' buttons until you see "fastboot mode" on the phone screen (alternatively, don't turn off the phone and instead enter fastboot mode via ADB (adb.exe reboot bootloader)).
4. Connect the phone to the PC via USB and open a command prompt in the location that you installed fastboot binary to.
Type (after each command press enter):
Code:
fastboot devices
To verify that the phone is recognized. And if it is type:
Code:
fastboot oem unlock
Now on the phone LCD navigate to "Yes" with volume buttons and press power to select it.
Your phone will factory reset, this will take a few minutes. Let it finish.
5. Put the TWRP image in your fastboot path. I used "recovery-twrp-3.2.3-crn-seoul(v3.2.3-1).img" downloaded from this URL:
https://forum.xda-developers.com/android/development/lenovo-s5-k520-twrps-t3863860
But I included 2 more files that I found (I did not try them).
6. Enter fasboot mode again and type:
Code:
fastboot flash recovery recovery-twrp-3.2.3-crn-seoul(v3.2.3-1).img
(Substitute "recovery-twrp-3.2.3-crn-seoul(v3.2.3-1).img" with the recovery filename of you choice)
7. If successful, disconnect the USB cable and enter Recovery mode, do not turn off or reboot the phone because upon restart the phone will revert to stock recovery (I.E. delete TWRP).
To enter Recovery mode press and hold 'Volume down'+'Power' buttons until you see "fastboot mode" and from there choose "Recovery mode" with the volume buttons and confirm with the power button.
(Alternatively, you can try holding 'Volume up'+'Power' to directly enter Recovery mode but I found it a little finicky)
8. In TWRP, swipe to allow changes. Press cancel when asked for a password to decrypt data.
If you chose to use a USB flash drive with an OTG adapter, connect it and mount it (Mount>usb-otg).
9. Go to Wipe>format data, type "yes" and confirm (if you have any data like installed apps, contacts etc., it will be deleted).
10. Go to Install and install "Disable_Dm-Verity_ForceEncrypt_12.16.2018.zip".
The files will be in (/external_sd/ or /usb-otg/).
11. Install "Magisk-v18.0.zip"
Important note: If you want to keep encryption (if you don't care if TWRP can't access /data/) and just obtain root, skip steps 9 and 10.
12. Reboot to system and wait for a few minutes for the initial setup.
If for some reason boot fails (nothing happens after 10 minutes) and you can still enter TWRP (hold 'Volume up'+'Power'), then you can revert the changes by restoring the stock boot image (TWRP>Install>Install image>boot.img - put a checkmark on "boot").
If this worked for you, please tell us by replying to this thread.
Thanks a lot man. This phone is a beast in quality/price when talking about hardware. Costs a bit more than 100€ and has the same hard than others at 180-200€ at least. Bad thing is software but with TWRP and root everything is possible . Just found what project treble is, amazing possibilities. Can't beliebe nobody replied yet to yor post. Its a great guide and you show all the sources from where your downloads come. As you said in another thread its better this way so people can trust your content more:

I am yet waiting for my Lenovo S5 to arrive but I will give this guide a try. I was about to follow XN logos (stupdroid) guide/software but I prefer yours. Just one question... have you checked whether the TWRP v3.2.3 (latest) from dmilz make proper working backups? Can I trust that a full backup will be loaded correctly after installing any unofficial ROM, to go back to stock if necessary? I made once the mistake of relying a TWRP and later I found out that one was ok for flashing but didn't create working backups. I asked him also the same question, but I guess you also tried yourself to make a backup and restore from it using TWRP.
Next step will be to flash an Android 8.1 or 9 GSI rom (did I already say I'm amazed by GSI/project treble roms? just found about them last days). I will update you about my luck following your guide
does anyone enable lte bands, 4 and 28?
just bought this phone, currently on shipping..
I'll first try with twrp + aosp 9 GSI
Hi man, have you upgrade to gsi

This means no rom is installed in your phone. Either you accidentally wipe system in twrp, or the rom is corrupted.
Download the deodexed stock rom below and flash with twrp. Should fix your problem.

Twrp gone
Hello sir thank you for this wonderful tutorial,
But I have a problem , after booting to TWRP , then boot to system after that when I try to go back to recovery mode TWRP , twrp is gone , stock recovery back
Since this device tends to bootloop easily and because I've seen lots of questions about it and information is spread across many threads and posts, I'm writing this guide to help you guys troubleshoot bootloops before asking generic "help me" questions.
I) Terminology
1) BROM - A readonly memory on the SoC that runs right when the device boots. Loads the preloader. SPFT talks to it after authentication.
2) Preloader - MTK firmware that resides on flash. It is loaded on the chip's SRAM. It is responsible for initializing DRAM, and is one way of authenticating SPFT (the other is authenticating directly with the BROM, but I believe the way thi is done is known only to MTK and OEM engineers, and not even to authorized service centers). It also loads LK. Its source is distributed to OEMs, but is otherwise unavailable. Plenty of leaks for other devices can be found on the internet (some from the OEMs themselves).
3) LK - Little Kernel. This seems to be the most common platform for Android bootloaders. Mediatek has its own proprietary branch. Same source status as preloader. As an android bootloader, it is responsible for loading recovery or usual kernel image, as well as fastboot flashing.
4) Kernel - If you're on these forums, you should know what it is. You can find it in boot.img
5) DTBO - The device tree for the linux kernel. It specifies which hardware is available on the device. On usual (x86) PC platforms, the BIOS and Option ROMs store device information and offer it to the kernel (through UEFI/ACPI). As arm boards do not have such those, the linux kernel uses dtbos which play the same role.
II) Boot process
1) The ARM cores on the SoC start and jump to the address of the BROM.
2) (I'm not very sure of this, there's too little information) BROM puts the cores into a known state, should listen on the in-build UART for some time (half a decade ago, some leaks said something about 150ms), and if it doesn't receive anything, it loads the preloader.
3) The preloader initializes basic stuff like DRAM (phone's ram), watchdog, USB, etc. If the phone is connected to SPFT, it talks to it and authenticates it (the (in)famous "Account not authorized for this operation" should come from a check in here). I believe it also turns on the charging light. On a normal boot, it further loads lk. I belive that it also shows the chinese menu on pressing the Vol- button on factory preloader, but I did not check this.
4) LK (the one that comes with factory preloader) checks if Vol+ is pressed, and displays the bootloader menu (the one with the 4 english entries). When selecting recovery, it loads recovery. If normal boot is selected, it loads boot.img and dtbo.img and I believe it makes some checks on them (possibly of signatures, see the kernel trees). It then loads the proper image from the logo.bin partition and displays it (note: I've checked Logo Builder; rebuilding the logo.bin partition with it makes LK reboot before showing any image - this is done after the boot menu); examples are the one where it shows "Unlocked" or the Fastboot background. It also checks vbmeta for verified boot. Then it boots the selected entry.
5) The linux kernel does some hardware init, mounts system and starts Android's init.
6) Android does its usual init, mounting vendor, loading modules and firmware, turning on stuff like wifi, bluetooth, gnss, etc.
III) Tips for diagnosing bootloops
1) When bootlooping, plug your phone in a computer and check for the following (this is from my experience):
a) Charging light turning on
b) Vol+ menu showing up
c) Redmi logo showing up
d) Charging light turning off
e) Boot animation showing up
2) Things to do based on where things didn't work as in (1):
If (a) doesn't turn on, you're most likely in deep ****, and I'm not sure who can help you. Edit: Try pressing Vol+ and see if a device with VIDID 0x0e8d:0x0003 shows up. That would be the BROM. If it shows up, try using SPFT (most likely won't work, but you have nothing to lose anyway).
If (b), try SPFT. If it shows "Account not authorized", you have the stock preloader. There's a couple threads here with some methods that may or may not work. Otherwise, ATM you'll quite literally have to pay for your mistake. Grab your wallet and your Windows VM. You'll need them. Be prepared to search for the least shady guy that can help you and have your usb passthrough (on the upstream hub) ready.
If (c) - i.e. you have the menu but no logo, this means you've got LK. Since the Redmi logo doesn't show up, it means something is not quite how lk likes it (and lk is very picky on this phone). If you can, you'll probably want to use fastboot and flash a known good image for whatever you changed. If not, use SPFT.
If (d) - i.e. you have the logo but the charging light doesn't turn off, this means LK didn't boot the linux kernel. Flash a different (working) kernel.
If (e) - the charging light turns off, but you have no boot animation, this means either the kernel panics before it can start Android or that Android failed to boot properly.
From here on, you can use /sys/fs/pstore/console-ramoops to diagnose the problem.
If you do get a boot animation or are close to it, you might also want to try using adb logcat (especially if you've turned on adb debugging, and your ROM can do it on boot).
3) /sys/fs/pstore/console-ramoops
You can access it on a normal boot on some roms (or mount it manually if you've got root), or it's usually mounted automatically on TWRP. This is the kernel log from the last boot and is theoretically stored in RAM (I have reasons to doubt that). Basically, it works like dmesg, but for the last boot.
While it is polluted by zealous MTK debugging info, scrolling through it can often show where the problem is. If you can figure it out yourself, great. If not, post it here, and I (or somebody else) might try to figure out what went wrong and put it on a list of known bootloop reasons and fixes below.
4) Recommendations on posting about bootloop problems:
I think it would help a lot specifying which step from above fails. Also, if the charging light turns off, please, please provide /sys/fs/pstore/console-ramoops. You can easily get it with adb pull from TWRP and it helps *a lot* in figuring out what went wrong.
Hope this info will help you guys getting your devices working again faster (and provide more accurate info when asking for help).
P.S.: Another reference on MTK boot, also around 5 years old.

OP, please add the infamous soft brick symptoms in detail, this maybe help someone in the future.
It shows redmi logo, it can enter vol + menu with some messages (I forgot the message), and it can enter vol - (bootloader), and it will ask for authorization when hooked to SPFT. And also link to that telegram post for work around.
And also, this is crucial info I found. Anything prior global 12.0.7 can be dirty flashed to anything prior that (even A10 to A9). 12.0.7 onward, 12.0.7 is the lowest you can get for dirty flash. I don't know for clean flash. Maybe work, maybe not.

What have you done prior brick? Do you do something like flashing global rom in a locked bootloader chinese flavor phone? If yes, do the unbrick with SPFT. If not, and you have unlocked your bootloader and access to fastboot, I think dirty flash will do the trick.
Sorry for being a lil' off-topic but I would love to ask how to prevent a bootloop after flashing back to stock recovery or/and boot. It happened twice - I used magisk+twrp, an update rolled out, I flashed the stock recovery for my official from (extracted from the official package) and ended up with a loop, did the mi authorized acc unbrick and it worked perfectly, now with the 12.5 rolling out I am preety sure i'll end with a loop again when I'll flash the stock boot or/and recovery.

you need to restore stock recovery and boot. and you can't install the update via updater nor twrp. install full rom via fastboot update or via mi flash (dirty flash is ok). but for 12.5 update, do it in twrp
from 12.0.7 onwards, downgrade without erasing data will lead to bootloop (just flash the correct build for remedy)
Thank you for your answer kekesed97.
Sorry, I made a small mistake. By saying that I used twrp means I had it installed not used for the flash. When the update came out, I thought that installing via ADB the stock recovery and boot will let me update the device like a completly unmodded model. Tried this Twice and always ended with a loop. Afterwards the only solution was updating via flashtools (it's bricked anyway so let's update manually hehe).
This will not work if your phone bricked after updating to Android 12. You should use the MSM in this case. This guide details downgrading to an earlier version of Android 11 FROM a newer Android 11. You have been warned.
This evening after updating my phone (installing to inactive slot + flashing with Magisk as I have done many times before), I restarted only to receive a Qualcomm CrashDump.
Unlike what I've read online, my one seemed to be a bit more severe. I could not boot into recovery mode (black screen; had to power phone off) and entering Fastboot did not fix the issue. After spending several hours reading through XDA, Stack Overflow, various other sites etc I finally managed to get it fixed. Not only that, but I kept ALL my data AND my root. It's like nothing ever happened.
The issues I faced:
- Mistakenly had USB debugging off (which cannot be enabled when your phone is soft bricked). This made using ADB for initial diagnostics virtually impossible
- Recovery mode showed a black screen; not accessible.
- Installing TWRP, only to find my device passcode (PIN) wasn't allowing me to decrypt my phone data so I could make a backup
- My phone was buggered
How I solved it: Given recovery mode was blank, I flashed TWRP to my recovery drive via Fastboot to bring it back. Because USB debugging was OFF and TWRP wasn't decrypting my data (meaning I couldn't back up any data or download the ROM to my internal storage without wiping it), I activated ADB Sideload within TWRP and then used this to downgrade my version of OxygenOS! After a reboot I received the Qualcomm error one more time, before it continued to boot into OxygenOS with all my data intact.
Your bootloader should already be unlocked. If it isn't, chances are you will be saying goodbye to your data
These steps may not work for everybody, but I wanted to give back what I learned from this, and it was rather unconventional and against the grain of what others have suggested. With that said, do so at your own risk.
This is a simple guide. I will explain the tools you will need and how to fix the issue. Anything beyond that (i.e. installing SDK platform tools) can be researched.
This is written assuming you are on Windows, although the steps are generally quite similar.
Tools Needed:
A computer to download and install:
- SDK Platform Tools/ADB (https://developer.android.com/studio/releases/platform-tools)
- TWRP for OnePlus 8 Pro (https://forum.xda-developers.com/t/...wrp-for-oneplus-8-8pro-official-beta.4341707/)
- OnePlus 8 Pro Drivers (You will need this installed if it isn't already for your phone to appear in SDK Platform Tools. You may need to disable driver signature enforcement on Windows 10)
- The version of OxygenOS you were running before the CrashDump occurred (https://forum.xda-developers.com/t/oneplus-8-pro-rom-ota-oxygen-os-repo-of-oxygen-os-builds.4084315/)
Steps to take - Initial Setup and Installation of TWRP:
1. Download everything above and then install SDK Platform Tools + OnePlus 8 Pro Drivers if you don't already have them.
2. Enter Fastboot mode on your phone and then connect it to the computer.
3. Ensure the TWRP .img file is in the same directory as your SDK Platform Tools install
4. Open up command prompt with SDK Platform Tools installed and type in
Code:
fastboot devices
Confirm your device ID appears along with "fastboot" beside it.
4. If the device is being recognised, we're ready to install TWRP. Note: Remember your Bootloader must be unlocked for the next steps. While in Fastboot mode, your phone will tell you if your bootloader is locked or unlocked. Now that we've confirmed it is unlocked, Type in:
Code:
fastboot flash recovery_a twrpname.img
followed by:
Code:
fastboot flash recovery_b twrpname.img
5. You can now boot into recovery mode! On your phone, use the volume keys to navigate and choose Recovery so you can enter TWRP
Downgrading to an older version:
When I installed TWRP, I was horrified to see that I couldn't decrypt my phone with my pin code. Apparently this is an ongoing problem with TWRP and the ability to decrypt your phone data varies between devices and builds of TWRP.
1. Now that you have entered TWRP, enter the "Advanced" settings and enable "ADB Sideload".
2. On the computer, type in
Code:
adb devices
. You should see your device appear.
3. Ensure the OxygenOS file is in the same directory as your SDK Platform Tools install
4. Type in
Code:
adb sideload updatename.zip
and let it flash to your phone.
And that's it! Reboot your phone. You may receive the Qualcomm error one last time, so kiss that sucker goodbye with a final reboot (I pressed power + volume up but then it continued to boot as normal; much to my surprise) and you should be good to go.
Hope this helps. This is my first ever guide, but my phone bricked itself this afternoon and it took me 3-4 hours of research to figure out what to do. This community played its role in helping me, and I'm sure someone out there will appreciate this information - definitely wanted to give back. I didn't see any information like this outside of wiping the phone entirely... I'm pretty stubborn and didn't want to do that.
This is definitely a "dirty flash", although given I couldn't even boot into the updated version, I would say a downgrade is definitely just fine in this instance.
I assume that you where using Android 11?
Because in the current situation with android 12 and hard bricking your phone with fastboot flashing this guide is potentially dangerous. As far as i know you should not flash twrp to android 12 right now.
Please correct me if i mixed things up here or if i am wrong. Its better to loose data and use MSM if you are concerned.
You might wanna include this guide in case someone needs to read it before doing anything.

[GUIDE] How to Avoid Killing Your OnePlus 8 Pro / 8T / 9R with OxygenOS 12 / ColorOS 12
As You can see, recently we started seeing more and more threads complaining about OxygenOS 12 killing people's devices. I lost my 8 Pro the same way few months ago and we finally know what caused this! ANSWER - THE BOOTLOADER! Massive Update...

Thank you and you're right. I've added this warning to the top of the post!
Hey, I have rooted a few of these and helped a few people as well and feel confident I can help most anyone with the problems they face rooting this beast. Also I'm posting this to have a place I can send people I help so I don't have to keep retyping stuff. From what I can tell the steps to root this phone are almost the same as the last model.
For now I will just post rough steps and use this as a place to provide support to people.
STEPS: (Rough guide/ please use other sources of information also)
1.) Fully update your phone
2.) Download the bootloader unlock app from asus official website. Also download and install Magisk. I recommend canary release.
3.) Get a patched boot.img or learn with a search engine how to extract the boot.img from payload.bin which can be found inside the large firmware zip files on the asus website (same link as unlock app but click firmware). Follow a tutorial.
4.) Turn on adb settings, and roboot into fastboot. adb reboot bootloader
For me for windows I needed to download fastboot drivers and go to device manager and install/update them.
5.) Unlock the bootloader with: fastboot flashing unlock
6.) Flash the patched boot image with: fastboot flash boot magisk_patched####.img
7.) Download safteynetfix and go to Magisk -> Modules and install safteynetfix.zip. Then go to Magisk -> Settings and enable Zygisk, and Enforce Denylist. Then turn on airplane mode and click on Configure deny list. add apps that are not working with root here, then delete their storage in App->Settings and reboot, remove airplane mode, and force close the apps in question.
For example select Show -> system apps. and add Google Play Store and Google play services to the deny list. Then go to App->Settings and delete both of those app's storage. Then when you reboot and remove airplane mode and force close google play and reopen it and go to Google Play -> Settings -> About you should see at the bottom "Device is certified".
If this last step does not show certified you did something wrong or I described it bad, check with a tutorial how to set up safteynet + configure deny list. Or post here and I will help you.
FINAL NOTE: After this the OTA updates that ASUS pushes will not be downloaded by our phone. We need to go to the same website we downloaded the unlock app from and we need to download the firmware files (WW for me) and put them in /sdcard/UL-ASUS-Al2201....zip and reboot. We then need to repeat the root process and the Magisk module process. Also I think we need to do this for every update along the way and cannot skip to the most recent update but not sure.
Hi! Thank you very much for sharing and helping. I have Tencent edition, from CN to WW, but a couple of things don't work properly:
- Android Auto does not communicate with my car (phone detected and bluetooth connected) bit app stops.
- Gboard voice dictation does not work (google assistant yes)
Country is WW. Safetynet passed. Play certified.
..I followed your guide.
I flashed the posted xda raw throuh fastboot and the the Magisk patched .img
When I tried TO apply latest updates (160) the Same message error appeared.
There is spmething strange (or are least I think It strange):
When I start in "fastboot" (black screen with capital text single line) my device isn'r recognized by PC. Then I switch to "recovery" and then to "fastboot" and a menu (several lines) with title "fastbootd" appears and the phone is recognized by PC (fastboot devices). If I choose bootloader the first screen appears.
I tried to reflash the raw but either the phone isn't recognized or a message appears on the cmd window showing "not rog 6" (more or less) and stops. But the phone is recognized everywhere as rog6...
I miss my broken rog2, it was much easier to root
Do you have any idea what's going on? Or when the twrp boot will be released so that I can brutally flash any zip?

I cant really help as I can't reproduce those problems. My phone was originally WW, but did you try to apply the non latest update? Then work your way up to 160?

To answer some other stuff, did you try looking in Device manager and maker sure your android device/asus rog is listed without an exclamation? I was having similar issues on windows until I installed the usb drivers. You should be able to run fastboot devices from within the bootloader menu.

Hi there! I flashed raw .134 and then the magisk patched boot .img as dedcribed in one forums guide, then tried to upgrade to .160 when I saw it on the asus support page. I was thinking of using edl and hard reset the phone and start again (in the next few days as it take times). I found a guide and tools (don't know if I can post the external link here). Do you think that could work? I downloaded raw .160 from the asus site (then i'll reflash the magisk patched boot).
To be honest it tickles me to try out this things (hoping not to end up with a brick of course)

I fortunately have several pcs so i switched to the one with no drivers issues. As written I can only use fastboot commands when the phone is in fastbootd mode (sort of recover looking screen). The bootloader mode (one line, capital letters) is not recognized by pc..that's why I was thinking about EDL and reflashing the first level boot. Is it hazardous?

I would continue to try to get my PC to recognize my Phone in bootloader mode using the drivers I linked. After helping 2 people who had windows, on both of their machines, I had to install the drives. On linux is just worked.
Also the raw image that I linked is of 93 so you should have needed to download 95, 97, 134, and 160 from asus. Then after 160 I repatched the boot img and re-rooted.
There is another person who said after tencent -> WW she was able to update to 134 where she had some problem. But I don't know how to reproduce that stuff Hope you figure it out though.

Phone looks certified, country WW, safetynet passed and upgraded to .160. Only 2 problema left: voice dictation of GBoaed and Android auto not working.
I tried several ways but they didn't solve. Voice dictation worked and then stopped: I guess something interferes... Android Auto app crashes although phone connects to car and is recognised.
Very strange behaviour...
Do you have any idea on how to reflash last .160 zip without twrp? Once installed it gets ignored by system when saved in home directory...
Everything else is working properly.
Isn't Android Auto no more (i.e discontinued).....?

what?!? where did you hear that? It'just something causing problems (compatibility issues with app or setting: magisk, modules, adaway, skipad, disabled system apps and so on). If I could manage to reflash the stock rom it'll work again (I hope)

Keep spamming flashall_aft.cmd until it works or try flashing other raw.
This worked for me if your able to get fastboot devices listed in adb firstly

I only have raw for .143 but I updated to .160*...can I use the previous version or do I get bricked? I don't trust anti roll back mechanism. I can live with this 2 "limitations" waiting for twrp and then be able to flash zip with no hassle.
*I downloaded source code from the Asus site but not sure how to use it (and unzipped is around 10 gb )
Thank you for this! I've been out of the root game for years but noticed with your post that I can hide root from Google Pay and my banking apps, so thinking of trying this. One question though - you mentioned that official updates need to be manually downloaded and the phone re-rooted. Would this wipe the phone each time?
fastboot driver doesnt support win64
Will the phone do a factory reset after unlocking the bootloader?
Anyone know if I root my phone following these instructions, will it factory reset or wipe my data partition? Sorry it's been a while since I rooted any phone, and I am excited about going this route

Yes, if you unlock the bootloader using the bootloader unlock app (which is a step that is missing in the original post), your phone will perform factory reset.
Troubleshooting
Once you boot into the bootloader with the adb reboot bootloader command, stay on the screen with the green START. Do not navigate to the fastbootd.
Use the side USB port to connect to your computer - not the bottom one.
Run the adb and fastboot commands in Command Prompt as Administrator.
Before you reboot into bootloader, remove Lock screen in Settings.
If you execute fastboot flashing unlock and you got FAILED (remote: 'permission denied'), just ignore it.
It's always better to install the latest updates, then download the firmware to your PC from ASUS Webpage and extract the boot.img and patch it in Magisk in the phone using this tutorial.
Thanks for the guide! Should add that you have to use the side port for fastboot to see the device. Was stuck for a while trying to figure out why neither mac nor pc couldn't find it when it was in bootloader mode - it was because I was using the bottom port lol!
Also if you want to disable verity and verification for the verified boot images, you have to do for both vbmeta.img and vbmeta_system.img. Didn't boot for me until I did that, and had to do an additional factory reset from recovery because of this.
