Worked on T-Mobile 11.0.6.8 KB09CB

Thanks a lot! Simple and effective!
[OnePlus 8T Guides, News, & Discussion] rohanhole:
Works Perfectly for my Indian Oneplus 8t 11.0.6.8 ( 7th Jan 2021) firmware.

whatever you store in /sdcard is not persistent , So dont forget to take img file to your local computer using Pull command.
[OnePlus 8T Guides, News, & Discussion] rohanhole:
Your next step would be

1) copy C:\Program Files (x86)\platform-tools_r30.0.5-windows>boot_b.img OR boot_a.img to Phone's internal memory using File transfer mode once android boots ( with connected USB).

2) Open Magsik ( if already installed ) or Install Magisk apk then after opening Click on install and Select and Patch file -> Select either boot_a.img or boot_b.img ( no need of to patch both files, concentrate on the current active slot one). You will get Output Patched file in Download Folder ( Magisk will display path)

3) copy that img file to to Your computer. then reboot phone with > adb reboot bootloader

4) fastboot boot magisk_patched_a.img or (b)

5) After booting into Android( which will be temp root) , open magisk and click on Install and direct ( recommended) method.

6) Reboot.

7) Profit.
[OnePlus 8T Guides, News, & Discussion] john.pszenny:
With the assistance of @magnefica for the SimUnlock, BIG THANKS! Followed directions in the OP post and worked flawlessly! NOTE: When booting the "patched" image, the boot process will take longer! Be patient!

I got my root back!! Apparently, my dumb self was rebooting the phone using the power button and not using adb reboot bootloader command. Geez.......sometimes, I need to "pump" the brakes. Thanks for the above!
[OnePlus 8T Guides, News, & Discussion] g96818:
if you say so. BTW, this is exactly the same as the very first rooting post.
[OnePlus 8T Guides, News, & Discussion] DavidUmana:
Hi, now that there is a new OTA incremental update (11.0.6.8) for the international version of the 8T (KB05AA), what would be the steps to update from 11.0.6.7, in order not to loose root? From what I see, there is still not a full rom available for 11.0.6.8.KB05AA.

Thanks in advance for your comments.
[OnePlus 8T Guides, News, & Discussion] Mpolo87:
I haven't tried updating yet, but there are universal steps in the other guides for keeping root (after you already have it). But if you do lose root after upgrading, this method should help you get it back without much hassle.
[OnePlus 8T Guides, News, & Discussion] DavidUmana:
Thanks for the info. The normal method that I have used before requires the Full Rom, to keep the Root. And because there is no full rom available yet for the international version of the 8T (11.0.6.8), I was wondering if there is a specific way to update with the incremental OTA and then use your method to get root back. The last time I updated with the incremental OTA it was kind of messy and after at least four reboots I got the update working without root, and then proceeded to use your method to root again. The part about being rooted and updating with the incremental OTA is the one that I am not sure how to do, without risking bricking the phone.
[OnePlus 8T Guides, News, & Discussion] demianrey:
The widevine is now L3 and cannot mount system, this root is bad
[OnePlus 8T Guides, News, & Discussion] Qnorsten:
The widevine status in related to unlocked bootloader, where devices with some systemids get downgraded to L3 on unlock, and some other keep L1. Seem to be related to something oneplus did when installing the widevine keybox to the trustzone.

Either way this is unrelated to the root method. Unless you find a way to get root with a locked bootloader.

What do you mean with mounting system? Mounting system in read mode should happen normally. Mounting system in read write mode isn't possible in any Android 10+ phones by design.

Couldn't find the best info but some mention about it here

https://twitter.com/i/web/status/1170404631865778177

. Either way this isn't related to the root method either.
[OnePlus 8T Guides, News, & Discussion] demianrey:
@Qnorsten Thanks for the info...

My previous phone was a Black Shark 2 pro running Android 10 I had no problem making changes to the system folder (uninstall apps) anyway... I install a custom rom, will I have access to the system folder? If so, which rom do you recommend?
[OnePlus 8T Guides, News, & Discussion] Qnorsten:
I don't think it will work in any custom rom based on android 10 either. If you read https://android.stackexchange.com/a/220920

But take a look in the custom roms forum here and see what people say.
[OnePlus 8T Guides, News, & Discussion] demianrey:
thanks again (this doesn't work for me "mount -o rw,remount /") I will check if any custom rom is possible to modify system .. yes with bs2pro could, I have hope
[OnePlus 8T Guides, News, & Discussion] cuiltheory:
Hey guys, I don't know where I went wrong, but I can't make or receive calls, and it takes ten minutes for the phone to boot up. I have the tmobile variant, and followed the instructions without any deviation.
[OnePlus 8T Guides, News, & Discussion] Jon.StatiK:
I just want to give a HUGE thanks for this guide. Worked like a charm the first time.
[OnePlus 8T Guides, News, & Discussion] amcferrin90:
Confirmed that worked for me too on 11.0.6.8. If it's not working for some, are you getting confused once you boot the recovery.img and issuing fastboot commands still. I did at first and was freaked because it seemed like the TWRP screen would flash on then screen blank. If you do fastboot devices you'll notice no devices in fastboot mode. But if you do adb devices you'll see your device is in recovery mode. The adb commands worked like a champ. That was pretty slick.
[OnePlus 8T Guides, News, & Discussion] iankscorpio:
I was able to root with this method no problem at all. After the game I play COD mobile would crash randomly. I was wondering if maybe it's because the bootloader is unlocked. Can I lock the bootloader now that I have root. It's greyed out now in developer settings.
[OnePlus 8T Guides, News, & Discussion] iankscorpio:
I think trying another method than this, and my phone would be bricked already.
[OnePlus 8T Guides, News, & Discussion] Scott:
Mpolo87, Great guide! Used it to root an 8T and an 8. Thanks for the "broken" recovery. That also worked on both devices.
[OnePlus 8T Guides, News, & Discussion] Cryopier:
Why would you reenable OEM Lock?
[OnePlus 8T Guides, News, & Discussion] iankscorpio:
When you are done rooting do you then lick the bootloader again?
[OnePlus 8T Guides, News, & Discussion] iankscorpio:
Not really sure just thinking the experienced people here would know if that's nesacry or not.
[OnePlus 8T Guides, News, & Discussion] iankscorpio:
I was able to root my phone you seen the broken torque package to make a boot image but when I unlock the bootloader it did wipe my device and so I'm wondering now if I could backup my apps cuz I went ahead and unrooted it I restored it and loaded my apps back up cuz call of duty mobile kept crashing on me and I didn't know why
[OnePlus 8T Guides, News, & Discussion] Scott:
Not needed. As a matter of fact, I tried to re-lock. It caused phone to go to crash dump mode with error.
[OnePlus 8T Guides, News, & Discussion] iankscorpio:
Thank you
[OnePlus 8T Guides, News, & Discussion] lordxcom:
No, if you do, it'll wipe and factory reset,loosing root.
[OnePlus 8T Guides, News, & Discussion] ilMerovingio:
I can't understand this sentence:

What does it mean? If I want to root it is because I don't have root yet 🤔
[OnePlus 8T Guides, News, & Discussion] Mpolo87:
To modify the system boot.img to enable root, you have to have elevated permissions- which you don't have by default. Making a copy of the boot.img and then transferring it back to your device as a standard file without those same protections lets you patch it to enable su. Then you use adb to boot using the patched boot.img (without overwriting your existing boot.img) so that while you're temporarily booted with it you do have root access- at which point you just patch your internal boot.img using the same tool, giving you permanent root.

It's also possible to skip the step of temporarily booting from the patched boot.img and instead just overwrite the unpatched boot.img, but that's risky- it's better to try booting from it first so that if it's not working properly you don't soft brick your phone.
[OnePlus 8T Guides, News, & Discussion] cdragon1982:
thank you this worked without a problem. had to change two file names 1. the img to img.jpg so i could upload to my drive cause my pc wouldent see the file. 2.the img again magisk made magisk_patched_oMFtJ.img i changed it to magisk_patched_a.img . i am using an 8T KB2007 T-mobile. thanks again.
[OnePlus 8T Guides, News, & Discussion] cdragon1982:
its supposed to be within 7 days, they never got back so i used the chat lastnight to find out whats going on and it was done this morning. YES!
[OnePlus 8T Guides, News, & Discussion] replica9000:
Thanks for this guide. Very simple. Just rooted from my Linux laptop.
[OnePlus 8T Guides, News, & Discussion] yeyitin:
Regarding COD mobile crashing randomly, it is probably due to root. Activision implemented a root control a few months back. Since then, it controls if your device is rooted and if it does find it is rooted, it ends the game and forces close.

I had the same issue in my OP 5T and I solved it following these instructions.
[OnePlus 8T Guides, News, & Discussion] live4thamuzik:
Worked great, Thank you!
[OnePlus 8T Guides, News, & Discussion] dogmatism:
This worked well thanks op.

At start after booting the partially working twrp, my computer didn't recognize the adb connection. I simply switched to my original cable which had a c port for the computer as well, and there it appeared.
[OnePlus 8T Guides, News, & Discussion] mad4some:
Ok, brand new OP8t from swappa ($560!!) just followed this guide and success! :D much thanks OP. I probably should have taken an available update before doing this but did not....So if taking an OTA update will break root, what is the easiest to get it back, redo this guide? or something simpler?...
[OnePlus 8T Guides, News, & Discussion] yeyitin:
Check the end of this post from another thread, it worked for me.
[OnePlus 8T Guides, News, & Discussion] replica9000:
I've tried updating with the OTA. Wether I update over WiFi, or try to apply from a local file, it always fails. I've even tried booting while un-rooted. I've seen others have had the same issue. They were able to update only after re-locking the bootloader. I'd rather not as it would wipe the device again. It seems I may have to wait for OnePlus to release another full update for the KB2005 variant.
[OnePlus 8T Guides, News, & Discussion] mad4some:
Thanks much, it's looking to me like a rabbit hole with OOS updates and root so I am not going to go down it o_O.......I have tried on each oneplus phone I've owned (5 now) to like Oxygen but each time I end up right back to custom rom's. A big fan of crDroid and it's available, so I'll be going that route.
[OnePlus 8T Guides, News, & Discussion] xb360:
I just updated. I remove root (restore image) from Magisk first then reboot. After that the OTA can be installed. No need to re-locking the bootloader.

After that have to do the whole steps from OP again to gain root.
[OnePlus 8T Guides, News, & Discussion] replica9000:
I was able to update when the full OTA was released, but not the incremental OTA. After install completed, i installed Magisk to the inactive slot before reboot. After reboot I had root already.
[OnePlus 8T Guides, News, & Discussion] druguman:
What could be the problem?

c:\Android>fastboot boot magisk_patched-22006_1iG20.img

Booting FAILED (remote: 'Unrecognized command boot')

[OnePlus 8T Guides, News, & Discussion] druguman:
I found the answer:

fastboot boot only works from bootloader, it doesn't work from fastbootd.

anyone knows how to hide magisk?

when trying to hide the app i just get both magisk and manager instead of just manager.

also wanted to say thanks for the great guide. worked great on my kb2003 oneplus 8t.

just need to make sure drivers are installed correctly for the device to show up in fastboot devices.
[OnePlus 8T Guides, News, & Discussion] noitsbeckky:
Just go into setting and tap hide magisk, and rename it so other app such as banking app doesnt recognize it
[OnePlus 8T Guides, News, & Discussion] orma1:
after trying this few times it worked eventually. thank you very much!

sometimes when hiding magisk the phone just get stuck and i need to restart. weird.

Hi

I received my KB2003 - Build OOS 11.0.5.6.KB05BA. It suggest me to update to 11.0.8.12.KB05BA but it's only an incremental updates. I unlocked it. Is this guide the one I need to follow ? Should I do the update before to root it ?
[OnePlus 8T Guides, News, & Discussion] noitsbeckky:
I think you're better off using the other root method so you wont lose root evrytime you update your phone
[OnePlus 8T Guides, News, & Discussion] Petitsurfeur:
But the other guide works only if we can download full update, not incremental, right ?
[OnePlus 8T Guides, News, & Discussion] noitsbeckky:
You can download Oxygen Updater from playstore and get a full size update from there if you havent updated your phone already

@Petitsurfeur
[OnePlus 8T Guides, News, & Discussion] replica9000:
With the phone unlocked, incremental updates fail.

When a full OTA is released, just download the full OTA, then:

- Magisk > Restore Images

- Settings > System > System Update > Local Upgrade (wait till finished/successful)

- Magisk > Install/Update > Install to inactive slot.

After a reboot, you should automatically boot into the other slot updated and rooted.

Where is the pulled boot.img stored after being pulled via twrp?
[OnePlus 8T Guides, News, & Discussion] BillGoss:
It will be in the directory from which you invoked ADB.
[OnePlus 8T Guides, News, & Discussion] acocalypso:
Two weeks ago I performed that magisk method which were working fine.

Today I wanted to update my phone and screwed it up as the latest stable magisk version was hiding the install to inactive slot method...

I had to reboot and magisk was gone... I tried it again - pulled the boot.img from the active slot, patched it with magisk and now I want to boot it with fastboot. After the boot animation the phone vibrates and goes to stock recovery.

Boot Reason: Rescue Party

Anyone tried that for the root method in this thread?
[OnePlus 8T Guides, News, & Discussion] replica9000:
I used this thread as a guide to root my phone.
[OnePlus 8T Guides, News, & Discussion] baxtex:
Yes but for updating OTA I mean? Or do you have to root for every OTA?
[OnePlus 8T Guides, News, & Discussion] replica9000:
You only need the guide in this thread once to get root initially. Once a full OTA is available, download it, then follow the steps in my post #91 to update without losing root.
[OnePlus 8T Guides, News, & Discussion] xb360:

Can you help me with this?View attachment 5348641

I know right? Thank god it didnt brick or anything after I restart but I had to redo the root but its good now
[OnePlus 8T Guides, News, & Discussion] baxtex:
I don't understand how to update. I have downloaded the full OTA.

What does the first step mean? Magisk > Restore Images, I cant find that option in the magisk manager app.
[OnePlus 8T Guides, News, & Discussion] replica9000:
When you open Magisk Manager, there's an option to uninstall Magisk. You can "Completely Uninstall" or "Restore Images"

I successfully rooted in OnePlus8TOxygen_15.E.24_OTA_0240_all_2103221851_61b94dd7e29

Retained root at the following OTA

Forgot the empty slot thingy for OnePlus8TOxygen_15.E.26_OTA_0260_all_2106020020_df4b6755d48e470a

Any ideas anyone ?

I updated to version to build 11.0.10.10.KB05BA and for some reasons install to inactive slot wasn't available.

anyhow I pulled the boot image and patched it with magisk.

After installation OS is no longer booting with bootloop at bootlogo....

I tried to use the ALPHA version of twrp from this thread https://xdaforums.com/t/recovery-11-alpha-teamwin-recovery-project-8t-kebab.4302449/ where gui is working.

I tried to flash magisk (latest) and got the same issue ...

It seems I'm stuck with the new ota and without root :(

Edit: while in bootloop open up adb shell.

magisk --remove-modules

this will fix the issue.

Absolutely brilliant rooting method, thank you so much for putting this together. I was able to very easily and quickly root the OnePlus 8T KB2005 on the latest firmware downloaded OTA, Oxygen OS 11.0.10.10.KB05AA.

SafetyNet was a bit of a pain, ctsProfile kept failing. But I used the XPrivacyLua method of circumventing it and it works great now.

Just followed your instructions to the letter and it worked like a charm.

Had to re-use this method today as I applied to new OTA and completely forgot to do the necessary Magisk steps. All is well again!

I thought I could cheat and set the active slot back to the previous rooted OTA to save time. Don't do it! I ended up in Qualcomm CrashDump mode and had to figure out how to get back to fastboot to set the active slot back.
[OnePlus 8T Guides, News, & Discussion] frankthetank5421:
Hello, I am hoping someone will be able to help me out. I have browsed the replies on this thread and another and I am a bit confused about the update process. I am rooted using a method very similar to the one in this post by extracting the boot.img and patching it; KB 2005 running build 11.0.9.9.KB05AA.

I attempted to run the OTA update by uninstalling magisk, selecting restore images, downloading the OTA, got to the page where it says "restart now", went back to magisk and installed to inactive slot, rebooted.

When I rebooted it looks like it didn't take the update. When I go to system updates the new update 11.0.10.10 KB05AA is sitting there waiting to be installed with a "restart now" button. I'm not sure what I did wrong, I'd like to install the new update and keep root, but I don't know how to proceed. I believe I have the original boot.img from before I rooted if I need it. Any help would be greatly appreciated, thank you.

( i posted this in another thread but posting here too for visibility, hope no one minds)

edit: after posting this I (stupidly) tried to repeat the steps with the OTA and installing to inactive slot, seeing if it would take the second time. This caused my phone to only boot to recovery. I went ahead and used the MSM tool to fix it, updated to 11.0.1.10, and repeated the necessary steps to patch the boot img and root. All is well now. However, I am interested to know what I may have done wrong when attempting this OTA update, so I know what to do for future updates.
