First, let me say that this is only an attempt to pull this information out from a lot of different threads that require a bunch of research and a lot of institutional knowledge of Android. The idea of this thread is going from 100% T-Mobile Stock 10.0.8 to Rooted Global Firmware.
Please take the time to read every step carefully. It'll explain a little bit as to the why behind some of the steps. PM me if I've missed anything.
This has been revamped as some of the steps are no longer required. Devices coming from 10.0.6 and below might have to try a different set of steps. Click here for the post with the old instructions
Requirements:
ADB setup and working
Global Fastboot ZIP Grab the latest version (10.0.8 as of 3/20)
For Root:
Magisk Canery apk
Modded-Boot.img From here or make your own pulling your own boot.img and using magisk to create a modded boot.img file
=-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-=
This group of instructions are going to walk you through on how to unlock your bootloader. This is the first general step in converting your device into a global device.
1. Either follow the rules via T-Mobile (paid off and 40 days on the network) or visit this thread and get the hook up from our friend (send him some cash, for real I did this and it worked hopefully he keeps up with this for a while!). This will allow you to use the Unlock App to permanently unlock your phone.
2. Open the "Unlock" app that's preinstalled on your phone and click on Permanent Unlock. If you have completed Step One correctly, it'll congratulate you and ask you to reboot your phone.
3. Reboot your phone and Enable Developer Settings. Check out the OEM Unlock button is now able to be switched off. Switch it off.
4. Be sure to also tick USB Debugging.
5. You'll now need to submit a request for an unlock_code.bin (could also be labeled unlock_token.bin) file from OnePlus via this link. It takes a week. Seriously almost down to the second. There's no avoiding this. I've read several people try (myself included) all met with the same fate. Wait. 7 whole days. You'll get an email from OnePlus containing the unlock_code.bin file. Download this file and save it to your ADB folder.
5a. Open CMD (with admin rights) and navigate to your ADB folder. I've heard users try to use Powershell and while it works mostly, ymmv. I stick with CMD and haven't had any issues.
Mine would be--
Code:
cd c:\adb\
6. Reboot your phone into fastboot--
Code:
adb reboot bootloader
Code:
fastboot flash cust-unlock unlock_code.bin
Code:
fastboot oem unlock
This will unlock your bootloader and wipe your device
=-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-=
Now that you've unlocked your bootloader, lets get to flashing the Global Rom--
7. Extract the contents of the Global Fastboot Rom zip folder directly into your ADB folder.
a. If you did this correctly your ADB folder will be filled with a bunch of new .img files. Like boot.img8. Open CMD (with admin rights) and navigate to your ADB folder. I've heard users try to use Powershell and while it works mostly, ymmv. I stick with CMD and haven't had any issues.
Mine would be--
Code:
cd c:\adb\
This will also wipe your data, be sure to save anything that you need prior to running the following command.
Code:
flash-all.bat
9. If you've never flashed via fastboot before, this is going to spit a bunch of information to you that might look like garbage. Your phone will boot a few different times including into FastbootD (link for explanation) But it's telling you what it's flashing and how fast it's doing it. There's a common looking error that happens every time you do this. It says "Invalid sparce file format at header magic". This is normal, just ignore it and keep waiting. Once everything settles, the device will reboot by itself. If it doesn't, like bootloops to the bootloader, start over and go back to Step 8 and try again.
10. You've now fully converted to the Global Firmware. Confirm this by going to settings > about phone and look at Build Number. Should say 10.0.8(as of the time of this post).
You're done! Continue on if you want to root your device...
=-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-=
If you're interested in root:
11. Boot the device from the modded-boot.img file to give your self temp root. Once this is done, boot the device.
Code:
adb reboot bootloader
fastboot boot modded-boot.img
12. Install Magisk Manager Canary from here
13. Check in the middle of the screen for "advanced options" and make sure Preserve force encryption and preserve avb 2.0/dm-verify are checked.
14. Now look under the first Magisk check and make sure that it's telling you there's an update to "Magisk" and run through that update via direct install.
15. Once that finishes it'll have you reboot the phone.
16. You've now fully converted to the Global Firmware and Rooted. Confirm this by going to settings > about phone and look at Build Number. Should say 10.0.8(as of the time of this post)

Shoutouts will go here soon.

First, let me say that this is only an attempt to pull this information out from a lot of different threads that require a bunch of research and a lot of institutional knowledge of Android. This will be a living first post as I'm currently not able to successfully get rooted. The idea of this thread is going from 100% T-Mobile Stock to Rooted Global Firmware. Once I can replicate and get root stable on my phone I will finalize this post. I will also add in shout outs to where I pulled this information from, both thread post and user, as it was through our group that I was able to piece this together. All this will be updated and make to look nice later.
The reason we flash to Indian and then Global is because if you don't, wifi/data and camera will be broken. I can't explain why it works, it just does.
Ok. Now to the good stuff. Please take the time to read every step carefully. It'll explain a little bit as to some of the why behind the steps. PM me if I've missed anything.
Requirements:
ADB setup and working
Global OTA ZIP (download from here)
Indian Fastboot ROM(download from here)
1. Unlock your bootloader. Either follow the rules via T-Mobile (paid off and 40 days on the network) or visit this thread and get the hook up from our friend (send him some cash, for real I did this and it worked hopefully he keeps up with this for a while!).
2. Move the Global Rom.zip file to the root of your OnePlus7T. It'll save you time later. Do this now or there's a later step where I give you the chance.
2. Open the "Unlock" app that's preinstalled on your phone and click on Permanent Unlock. If you have completed Step One correctly, it'll congratulate you and ask you to reboot your phone.
3. Reboot your phone and Enable Developer Settings. Check out the OEM Unlock button is now able to be switched off. Switch it off.

7. Open CMD (with admin rights) and navigate to your ADB folder.
Mine would be-- cd c:\adb\
8. flash-all.bat
9. It will also ask you to wipe data. This is your call. If you followed Step 2, this will wipe out this file and you'll need to replace it once your phone has converted.
9. If you've never flashed via fastboot before, this is going to spit a bunch of information to you that might look like garbage. But it's telling you what it's flashing and how fast it's doing it. There's a common looking error that happens every time you do this. It says []. This is normal, just ignore it. Once everything settles, the device will reboot by itself. If it doesn't, start over and go back to Step 5 and try again.
10. Once the device boots up, you should now be on the Indian build for the OnePlus 7T.
11. You should have already moved the Global OTA to the root of the OnePlus 7t. If you haven't, do so now.
12. Go to settings > system updates and look for the gear on the top right-hand corner. If it's not there, something didn't flash right. Go Back to Step 2 and try again. Click on it and select Local Upgrade
13. Select the Global OTA file and it'll start to flash from within the update app.
14. Once that finishes it'll have you reboot the phone.
15. You've now fully converted to the Global Firmware. Confirm this by going to settings > about phone and look at Build Number. Should say 10.0.6(as of the time of this post, I'll try to update this as I can)

This is where we should be able to root. Once I can verify getting this setup and replicate it I will continue with the tutorial. Hopefully, everyone who reads this will find it helpful.

I'm having a issue when inflash globel my phone stays on Indian firmware
Are we 100% sure that WiFi/Data/Camera will be broken if you just go straight to Global? Because just this morning I flashed from TMO 10.0.4 to Global 10.0.6 using the fastboot flashable ROM with perfect VoLTE/WiFi/Camera...
Also fully rooted!
Edit: Updated to 10.0.7, kept root via Magisk Manager install to inactive slot.
Reserved for old instructions. Going from 10.0.7 and up the instructions were changed and certain steps weren't needed, like flashing Indian before Global.
Keeping these here just in case someone purchases a phone with older firmware and doesn't want to wait updating to the latest version.
Requirements:
ADB setup and working
Global OTA ZIP (grab the 10.0.6 from here)
Updated 10.0.7 OTA Build from hereas well
Indian Fastboot ROM(grab the latest from here)
Pre-Rooted 10.0.6 boot.img file here

2. Go to Settings > System > System Updates and look for the gear in the top right.
3. Select Local upgrade and select the update file for 10.0.7.
4. Let it run through and finish, don't reboot.
5. Open Magisk Manager
6. Update and select direct install to inactive boot partition to update.
7. Once this finishes, reboot and you're now on 10.0.7 rooted.

Yup, tried to be slick by going straight to Global and ran into this problem. Data worked for me but Camera was super unstable and Wifi was the only solid no that I got. Required more research to discover that this issue is avoided by flashing the indian rom first.
Tell me more about this. What steps did you take to do this? I'm thinking that once you flash the global ROM to reboot, and then use the a image-new.img that boots a temp-magisk to then use magisk canary to install magisk on the inactive slot (should be a right?)
Click to expand...
Click to collapse
Hmm I'll watch and see if my Camera is unstable but it seems fine so far.
To root I flashed (not booted) a 10.0.6 Magisk patched boot img (fastboot flash boot patched_boot.img) that someone posted in the "how to patch boot with Magisk" thread and installed Magisk Manager Canary.
I used Oxygen Updater to local update to 10.0.7 (it says 10.3.0 because of a typo from OnePlus, see another thread. It says 10.0.7 in settings) but make sure to download the full 2gb update not the 200 something mb incremental one because it will fail.
Then when the update is done, don't hit reboot, go to Magisk Manager, make sure you're set to the Canary channel (unless you patched the boot img yourself with something else) and install and choose inactive slot. Then you can hit reboot in Magisk.
Perfect, means I was thinking correctly with an extra unneeded reboot. Updated info in OP.
Just now noticed this thread so I'll crosspost my applicable results from the MSM thread https://forum.xda-developers.com/showpost.php?p=81227253&postcount=113
I want to share my experience in case it might help someone else as I was quite confused for a while over the past few weeks trying to get off tmobile slow updates.
I can also confirm jumping straight from tmobile 10.0.4 to global 10.0.6 works. I didn't have the 10.0.7/10.3.0 downloaded and I have slow internet so I can't say if that would work but I have upgraded to it since via oxygen updater.
Basic steps how I got there is, assuming you know how to do stuff like enable dev mode and usb debugging
-sim unlock https://forum.xda-developers.com/oneplus-7t/how-to/t-mobile-free-op7t-sim-unlocking-t4014053
-request bootloader unlock token and wait 7 days https://www.oneplus.com/unlock_token
-unlock bootloader
-get fastboot rom https://forum.xda-developers.com/oneplus-7t/how-to/rom-stock-fastboot-roms-oneplus-7t-t3979213
-use all in one tool to flash flashboot rom https://forum.xda-developers.com/android/software/tool-tool-one-driversunlocktwrpfactory-t3358711
I told the AIO tool I had a oneplus 7 (7T not an option) and did "flash factory images", and chose wipe and reboot to be safe and just waited until the phone came back to factory setup screen
that's it. oxygen updater incremental update failed for 10.0.7/10.3.0 but full worked fine, I've never used oxygen updater until now so idk if that is fairly normal or not. VoLTE works, WiFi calling, etc all seem to be working as far as I can tell (although it seems the global doesn't have the quick select option to disable wifi calling like the tmobile rom did).
I've also now installed Magisk Canary, patched boot img and have certified play store now and google pay is fully functional and I have used camera for mobile banking deposit. Still no issues with wifi, camera, anything
Once converted to Global oos, will it support Dual SIM?

I clicked on it and it worked, but I didn't check through mobile. Can you show me what happens when you try?
There is no link to request unlock file from OnePlus. Also will regular global OTA updates work? Or will I have to manually update every time?
Will this work for McLaren 5g?
I just followed the instructions in post#7 and was able to do this successfully as well (direct Tmobile->Global, without the Indian version flash in between). Note that the phone will reboot sometime in the middle of the flash, do NOT manually go into the phone and reboot yet again, just wait for it to complete.
Is waiting around for OnePlus to send you an unlock token really necessary to unlock the bootloader? I ask this because it's not necessary on the OP7 with the use of the MSM Tool (https://forum.xda-developers.com/oneplus-7-pro/help/how-to-convert-tmobile-op7-to-t3935947) Would this tool work on the OP7T or does it need its own?

i guess thats why i can unlock the bootloader and convert the Tmo 6T without asking the unlock_code.bin from oneplus. thank you kindly for the info
I got the unlock bin today I just flashed via fastboot received message the bootloader is unlocked, but the device status still states locked?

Hello Team,
Well, I wish that there was a special special section for the Honor 8X MAX, as there was so many things we can add to it, but well, let's post in this section
Most devices that came with Android 8.1 are likely to be Treble GSI compatible, so, the thng is that you just gotta find what Partition it uses.
For this device, it was kinda tricky as it was supposed to be A partition but I found out that it on EMUI 8 neither or AB worked, so after several tests, I found out that using any EMUI 9, we gotta use AB and not A, so I tried LOS 17.1 and worked like a charm but as TWRP is not the best for this device and I did not want to bother decrypt it, then root and install GAPPS, I preferred to install AOSP 10 from phhusson now and it works like a charm. The pros of this rom are that it is already "Rooted" and "Gapped", so I would highly recommend it :good:
Requirements::
* Unlocked Bootloader (Not explained here, so you need to use HCU Unlock and purchase a credit for that);
* Your Recovery has to be stock, so if you have TWRP, I recommend to reflash the stock one;
* Choose an ARM64 AB GSI Rom from here;
BUGS:
1. The device might show as not certified, so you won't be able to use any Google services until you register your device. Guide from Androidsage to help doing that;
2. Brightness seems to be at 50% when set at a maximum. This issue might be due to the Vendor Overlays (not a 100% sure though), I am investigating this, but I am using the device as it is and it is fine for me, until we find a solution for it.
Quick Guide:
1. Turn off your phone and then start it with Power and VOL+, until you see the message of the unlocked phone;
2. Wait until you see the Stock recovery not eRecovery;
3. Wipe and reset, Type "YES" and wait for wiping;
4. Plug the USB Cable to PC, reboot the phone while pressing VOL - ;
5. You should see the Android Fastboot now;
6. On Windows download ADB tools and Linux or Mac they can be added using terminal (You can find it easily by doing a simple search);
7. To make sure the phone is correctly connected, type in the CMD Line or Terminal: fastboot devices ;
8. You should see a series of numbers, so now you can flash by typing: fastboot flash system WHATEVERGSIIMAGEYOUCHOOSE.IMG ;
9. Wait about 2-3 minutes and then when the flash is finished, type: fastboot reboot ;
10. That's it! Your phone should now boot to your preferred GSI ROM with more or less everyhing working

Hi,
Great job, very detailed.
I've faced a situation when trying to flash many GSI img's (Lineage 18, Pixel Exp+, AOSP). The recovery (stock then TWRP) returned "image is too large for the partition". I've ARE-AL00C (4/128) with unlocked BL. Is there any workaround ?

Some images simply do not work, so you will need to check for other images simply.
Just install this one : https://github.com/phhusson/treble_...nload/v222/system-quack-arm64-ab-gapps.img.xz
root&gapps&backlight working
of course you'll need Device+ID.apk and register ID with Google but that's easy and simple
Device: Huawei 8x Max AR00
The Quack version works but sadly it is Android 10. I have found many Android 12L GSI roms that I would like to use but the brightness is an issue on all of them. Anyone know how to copy the Quack backlight vendor display and patch it to the newer GSI roms? Tried buildprop GSI wont boot (Crdroid, Lineage 19) Tried Dirty flashing, obviously didn't work. Can't seem to find the file containing the slider brightness limitations. Phherson gives rom backlight options and tried several combinations, and yes rebooted everytime none of them work. Any ideas?

For this device, it was kinda tricky as it was supposed to be A partition but I found out that it on EMUI 8 neither or AB worked, so after several tests, I found out that using any EMUI 9, we gotta use AB and not A, so I tried LOS 17.1 and worked like a charm but as TWRP is not the best for this device and I did not want to bother decrypt it, then root and install GAPPS, I preferred to install AOSP 10 from phhusson now and it works like a charm. The pros of this rom are that it is already "Rooted" and "Gapped", so I would highly recommend it :good:
Requirements::
* Unlocked Bootloader (Not explained here, so you need to use HCU Unlock and purchase a credit for that);
* Your Recovery has to be stock, so if you have TWRP, I recommend to reflash the stock one;
* Choose an ARM64 AB GSI Rom from here;
BUGS:
1. The device might show as not certified, so you won't be able to use any Google services until you register your device. Guide from Androidsage to help doing that;
2. Brightness seems to be at 50% when set at a maximum. This issue might be due to the Vendor Overlays (not a 100% sure though), I am investigating this, but I am using the device as it is and it is fine for me, until we find a solution for it.
Quick Guide:
1. Turn off your phone and then start it with Power and VOL+, until you see the message of the unlocked phone;
2. Wait until you see the Stock recovery not eRecovery;
3. Wipe and reset, Type "YES" and wait for wiping;
4. Plug the USB Cable to PC, reboot the phone while pressing VOL - ;
5. You should see the Android Fastboot now;
6. On Windows download ADB tools and Linux or Mac they can be added using terminal (You can find it easily by doing a simple search);
7. To make sure the phone is correctly connected, type in the CMD Line or Terminal: fastboot devices ;
8. You should see a series of numbers, so now you can flash by typing: fastboot flash system WHATEVERGSIIMAGEYOUCHOOSE.IMG ;
9. Wait about 2-3 minutes and then when the flash is finished, type: fastboot reboot ;
10. That's it! Your phone should now boot to your preferred GSI ROM with more or less everyhing working

After trying many different gai variants and versions I found they all have an issue with browsers. Both chrome and edge freeze after scrolling a bit. I'm wondering if this because the GSI uses too much storage space and cannot buffer? Tried to port GSI onto other partitions such as cust, prod didn't work. Even Magisk flashes successfully but does not appear in the rom. The a and b is confusing like EMUI uses both and the TWRP does not decrypt and no Verity commands don't work either. The havoc rom seems to work the best with gapps pico flashed.
~ Android 12 backlight issues had to revert to android 10
~ All GSI have the common browsers freezing. Have to use VIA browser (basic)
~ Magisk won't install have to port to ramdisk, but isn't that the TWRP recovery?
Hello, which one is the Qualcomm driver to be installed for sdm660?
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.
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.

hello..
So... /sys/fs/pstore/dmesg-ramoops .. is not there .... /pstore do not exist :-\
and /proc/last_kmsg.. neither :-(
i have.. lineage-14.1-20190213-nightly-asanti-signed install it....
He will be generating them elsewhere???
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).
AT THE END OF THE DAY (week actually) this won't work for U.S. based phones as far as I could find. Huawei partitions etc. are all ****y and I can't update firmware beyond EMUI 8 because the sites are all down/gone so RIP me and my week of working on this dumb ****. Save yourselves, don't attempt if within the U.S.
I tried a billion things, but eventually I ended up taking my phone apart and getting access through the dev test point and potatoNV. Once fully unlocked I attempted to flash various images, but end up in boot loops until I reinstall EMUI. I'm presuming my problem is with finding a proper image? Let me know if you know otherwise, but I'm looking for latest Android version with GAPPS that will work on the Honor 7x please!
If you're reading this, just ditch the phone or deal with what you have. Leaving the following info in case anyone is stubborn enough to give it a shot, but I highly do not recommend it.
Taking notes for myself if no one comes out of the woodwork
I managed to reach the 313 logo (ducks), but froze there with https://github.com/phhusson/treble_experimentations/releases/tag/v313 (aonly GAPPS)
Still would love assistance/input. I've tried a bunch of different images including 'a only' and android 10, but still hitting issues. Not sure if SparseConverter is helping or hurting either
Tried
system-squeak-arm64-ab-gapps.img.xz
system-roar-arm64-aonly-GAPPS (chunked and not)
system-arm64-aonly-gapps-su.img
dotOS-R-v5.2-arm64-ab-GAPPS-OFFICIAL
system-quack-arm64-aonly-gapps = new android logo boot screen loading forever
Havoc-OS-v3.12-20201230-Official-a64-aonly - spooky, never got out of bootloader
For anyone else doing this, items I've read say that factory reset should be done before AND after flashing system.
I feel like there is a RAM limitation on some of these later android OS, but here's some more info
honor7x is KIRIN 659 arm64 a-only partition
POST FLASH INSTRUCTIONS
After entering the reboot command, your 7x will reboot and you will see the warning screen where it tells you that your device is unlocked. On that screen "PRESS AND HOLD THE VOLUME UP KEY" to boot into erecovery to perform a Factory Reset. If you do not, the phone will boot loop until it forces you too.
per https://github.com/phhusson/treble_experimentations/wiki/Huawei-Honor-7X#post-flash-instructions
I have been scrubbing the asshole of the internet to find this information.
honor7x is KIRIN 659 arm64 a-only partition
adb shell getprop ro.treble.enabled = true
HOWEVER
the device isn't fully VNDK-compliant (https://source.android.com/devices/architecture/vndk), and the device can use only the GSI for the same on-device OS version. For example, an Android 9 (API version 28) device that isn't VNDK-compliant can load only an Android 9 GSI image.
per https://developer.android.com/topic/generic-system-image
so we're (allegedly although I've seen otherwise) stuck with android 8 Oreo (in my case U.S.)
no TWRP download for 7x specifically...using 7 = 3.1.10 then
installed magisk https://forum.xda-developers.com/t/...10-mate-10-pro-huawei-treble-devices.3749280/ is a useful guide
Installation

topjohnwu.github.io
https://androidfilehost.com/?fid=673956719939832043 = boot.img
adb push -p BOOT.img /sdcard/
(on the pull they ****ed up the _ and -)
device does not have a separate vbmeta partition, JUST KIDDING found one at /dev/block/platform/hi_mci.0/by_name when checking for boot
adb reboot fastboot
trying with recov because boot gave me partition length get error...
(img1)
idk at this point because a lot of people have TWRP that I'm unable to get because of this^ and I don't think this garbage phone even has a boot partiton? (img2) but has two recovery partitions per https://forum.xda-developers.com/t/honor-7x-bricked.3973247/

probably a type III device for magisk...
adb pull recovery_ramdisk
adb pull ramdisk
didn't work
grab path for twrp
/storage/sdcard0/Download/twrp-3.1.1-0-plank.img
flashing recovery gives same partition length get error
fastboot flash recovery_ramdisk twrp.img
STOP HERE pretty sure this is the step where I screw myself and at least my phone still uses safe mode, but I don't have a recovery.img
imagine drowning phone by holding vol +, vol -, and pow. get spooky err screen (no recovery img failed)
got emui screen
hold pwr vol + to get normal (not ereco) recovery. Still ****ing boned so trust pmMeYourFlipFlops at this point.
I'm currently on emui 8 vendor
