Bootloop after root atempt - Google Pixel 4a Questions & Answers

Hi,
I have a Pixel 4a from google store. I had the october update on Android 11.
I followed this tutorial to root my phone : https://android.gadgethacks.com/how-to/root-android-11-pixel-4a-every-step-covered-detail-0333038
After doing the step 16 (magisk), my phone booted with the Google logo for a long time.
Then I went to the donwload mode, I have the error message "Your device is corrupt. It can't be trusted and may not work properly."
What should I do to re install android and to get my phone rooted ?
Thanks

You had the wrong Magisk version, so it patched the boot.img wrongly.
On Android 11, one must use the newest Canary version of Magisk.
Get the newest Platform Tools (important!), get the newest Full OTA from Google's website, flash it via the flash-all.bat which is included.
Then repeat the rooting process with the right Magisk version.

Thank you for your answer.
I'm so afraid of downloading the wrong files and bricking my phone, would you mind sending me the links of the things you told me to download ?
Thanks

[TESTING] Flash Patched boot.img to achieve Systemless Root

WARNING:
Please do every preparation that could fix your phone to original state before doing this trick.
DOING THIS MAY VOID YOUR WARRANTY, DO IT AT YOUR OWN RISK
I managed to unpack the official firmware of Nokia 7 and 8, and patched their boot.img with SuperSU Systemless Root.
But I don't know if it works on them.
Patched boot.img can be downloaded at:
https://mega.nz/#F!igsBmarT!3rIjD4ZaZN8ueOTVmciGwg
Here's the method you need to do:
1. Install OST LA and patch it, and OPEN IT FROM INSTALLATION DIRECTORY DIRECTLY.
2. Flash required firmware before proceed. If you don't do that, you won't be able to access Wi-Fi after the boot.img flashed.
For Nokia 7, you need to use the firmware "C1N-0430-0-00CN-B05" which I haven't released to public for some reason.
For Nokia 8, you need to use the firmware "NB1-435J-0-00WW-B01" which released in this topic: https://forum.xda-developers.com/showthread.php?t=3678487
If you've already flashed required firmware before proceed, you can skip this part.

3. Use the Service Purposed Bootloader trick I've mentioned in the Nokia 6 Root Guide: https://forum.xda-developers.com/showthread.php?t=3702354
4. Type these commands:
Code:
fastboot-android flash boot_a E:\NB1-435J-Boot-Patched.img
fastboot-android flash boot_b E:\NB1-435J-Boot-Patched.img
fastboot-android reboot
For Nokia 7, use C1N-0430-Boot-Patched.img instead. I've attached the Firehose, rawprogram0 and patch0 for Nokia 7 in case you want to use EDL Mode on Nokia 7.
Click to expand...

5. If it's accepted by the system, the phone will reboot twice, and you'll see SuperSU appeared.
However, if "Verification Failed" appeared on your phone, then the trick failed. You have to flash original firmware to restore your phone to factory state.
If anyone know how to fix that in boot.img, that's a breakthrough of Nokia Android Devices.
You may want to use Flashfire to flash Xposed Framework or something else, but DO NOT RECEIVE ANY OTA UPDATES after your phone rooted.
I'm looking forward to a boot.img manual patcher on PC or Phone available, which could patch boot.img to achieve Systemless Root either SuperSU or Magisk and bypass Verification Boot.
This looks exciting. I have to look deeper into recovery options before I dare this kind of experiment...
Tried on a retail Nokia 8 TA-1052 running 00WW_4_35J_SP01
Boot passed but unfortunately no root
End up having to upgrade to 4390 using 4G
Update: Can't install 4390 even when I download the update multiple times. Flashed 435J using OST and tried flashing the kernel again but still no root.

Thanks for feedback.
I'll check if anything wrong.
Can you check if you can install SuperSU manually from Google Play?
After you installed it, is root available?

Nope. SuperSU said "Root not available"
Many thanks for your efforts on this patch, I would love to be able to root my Nokia 8.
Having an unlocked bootloader I am not really worried about, but having root access is a big feature for me.
Any chance this patch will become available to firmware version 00WW_4_390 which is the current latest? (And what my phone is currently running)
Not sure if I can downgrade it to NB1-435J-0-00WW-B01 or not, but I can try that if it is not able to be patched to the latest firmware image.
Thnx hikari_calyx for your hard work!

If you have a locked bootloader, you can't do anything.
Magisk and root is separate to TWRP on this phone. This image will help you get Magisk installed.

Hi a1291762, as a noob could I ask you a few questions please?
Wanting to downgrade from Q to Pie, could I used your 10.0.20.0 vanilla boot with the Mi Flash Tool using the steps here, and then if I wanted to add root I could use the 10.0.20.0 patched boot with the guide here?
Thank you!

You might want to check that people have been able to downgrade. I know that pie-oreo caused a modem issue.
You need a fastboot image to downgrade. Unless MiFlash has magic (I have never used it).
https://forum.xda-developers.com/mi-a2-lite/how-to/fastboot-xiaomi-mi-a2-fastboot-images-t3824871
Looks like you'll have to downgrade to 10.0.18.0 and then apply the 10.0.20.0 update, since I do not see a fastboot for 10.0.20.0.
You won't need the vanilla boot image because it is in the fastboot image.
One you have 10.0.20.0 installed you can use the 10.0.20.0 patched boot to install Magisk.

Much appreciated, I had thought your vanilla boot and the fastboot images were the same things, once I downgrade to 10.0.18.0, how would I apply the 10.0.20.0 update as I assume the next xiaomi system update would skip straight to the latest Q build?

I'm not totally sure...
There are links to the OTA zips around. A thread about Android 10 showed how to install one using the stock recovery... I guess the same works for 10.0.20.0?
As a Linux user I would be inclined to try and use command line tools to install the OTA zip... But I don't even know if that's a thing

Thanks dude, I did find it here in the posts, I guess the OP isn't updated anymore, I've just had too many problems with Q, it sucks imo, once I back up everything I'll give it a go, by any chance do you know any good app and general backup apps that make things easy?

I bought titanium backup pro a long time ago and still use it. Back in the day, the free version was annoying for whole device restore. But it's let me move across 5 devices and saved me from losing data on many occasions so I consider it money well spent.
I backup and then rsync /sdcard to a computer daily (CLI tools from cron). For restore I copy the files back (if needed) and then restore.
I only backup user apps, call history and SMS. System apps don't restore properly these days.

I just checked my 4a with the Check for Updates button under settings and Android 11 is there waiting for me to d/l and install.
I successfully applied the OTA update, then extracted the boot.img from the full image (both versions matching RP1A.200720.011), patched with Magisk, and then flashed it, but now phone wont boot. Just getting the G startup logo for over 10 min now. Has anyone had success with this method? Is there a better way to do it?
Just updated with no issues, but I'm not rooted yet. Only thing I really want is custom accent color (red), so not sure if it's worth rooting.
Sent from my Pixel 4a using XDA Labs
hate to say it but I think at this point that Magisk 20.4 (Manager 7.5.1) cannot root Android 11 on this phone. I have posted this finding on the rooting thread asking if anyone has had success:
https://forum.xda-developers.com/pixel-4a/how-to/guide-unlock-root-pixel-4a-t4153773/page4
I unrooted, applied update, installed Magisk Canary build, patched boot image from downloaded Factory Image, fastboot flash boot... and have successfully rooted my 4a on w/11.
Well I got an email from Google saying that android 11 was waiting for me to download. So I checked updates and it says my device is up to date. So I guess maybe verizon does hold up updates.

where did you find it? nvrmnd https://github.com/topjohnwu/magisk_files/tree/canary
@tcat007 @fronto
For anyone looking to root, you need magisk canary, latest build at time of writing (20424) works fine for me. Took the OTA from 10 to 11 following the magisk OTA update guide here worked like a charm: https://topjohnwu.github.io/Magisk/ota.html
However, somethings seemed to have changed in 11. For audio apps like jdsp and v4a, you'll need to run this in terminal (only needs done once):
Code:
su -c settings put global hidden_api_policy 1
Also note that sbin is gone too (least on pixel 4a) so v4a app install won't work properly (it's being worked on)

You only need Canary to create the patched boot file. After it's been flashed, you can run Stable.
Just flash the pre-patched boot file and keep stable:

Yeah I dont like that canary Magisk so I used your advice and flashed the patched boot.img and then went back to stable Magisk. I am a little underwhelmed with Android 11 maybe its just me.

Thank you for the upload. Can this be flashed in magisk? I presume no.
Can you clarify the steps? I'm already on android 10 rooted.
1. Uninstall magisk / Restore image
2.. Download install Android 11 / no reboot
3..... ? Then with patched boot.

Its not flashed in Magisk. Its flashed using fastboot via a computer connection. With that file, you never need to touch Canary manager.
1. uninstall Magisk but you keep Magisk Manager
2. update to Android 11 via OTA or with full image provided you revise the flash-all to not wipe, or just manually issue each command.
3. make sure your 11 is up and running
4. reboot to bootloader, connect PC
5. fastboot flash boot magisk_patched_sunfish-rp1a.200720.011.img
6. reboot and open regular stable Magisk Manager
enjoy
I've rooted my 4a with magisk with the Aug factory image (android 10). I have the both Titanium Pro and Mybackup Pro - Do either of those programs create an image backup similar to the image I create of my PC using a program like Acronis, so that I could just re-install the Android 10 system if I don't like Android 11? If those programs don't do that is there any program that will do that?
Has anyone else noticed x google enrollment then updating message every (re) boot? I must have done something wrong. I got magisk working nicely. Can install itself, modules, ctsProfile is true, whatevs... But nothing else gets a su toast. Not too worried with it this first week or so.. I'll stab again weekend after next.

Accidentally OTA updated my pixel, all fine but root gone

So i accidentally updated my pixel firmware via official OTA update (security patch 5. january 2021). First i was scared of a bootloop but it all went fine and booted.
Of course my root is gone now, but i want to root it again. Bootloader is still unlocked. Does anyone know, if i can just flash the magist boot.img again and it will boot fine? Or is there a risk that maybe THIS will cause a bootloop?
Thanks!

No you don't. You only have to repatch the new boot image when a new major Android revision comes out. For example going from Android 11 to 12. I've updated my Pixel 5 every month a new update comes out. And I've always used the same boot.image file. No need to keep wasting your time patching that file. When you look through the OTA files you'll notice that none of those files in the zip file are a boot.image file. Meaning it doesn't touch it when it's doing the OTA.

That is kind of useful, thank you for sharing. Can someone confirm this?
@hanni2301 Have you succeeded in getting root back ? I got the same problem today....
Why do you ask me?
I always patch the actual boot.img out of the monthly factory image with magisk (beta or Canary) first and flash then the factory image, reboot, flash boot boot.img and afterwards the custom kernel.
@xT29c said that you can reuse ure patched boot.img from last month, as it changes only between different mayor Versions.
So you can save some time, but the process is still the same.
IMO, yes, you should always patch the new boot.img from each months new factory image in Magisk when re-rooting.
Do you need to? i suppose that's up to you. However I think you should want to.
Essentially, you're missing out on any code changes/fixes, etc that Google may have added to the new months kernel.
~ Maybe an idea for a new thread to upload the Pixel 5 stock boot.img from each months new OTA, along with a Magisk patched boot.img. ~
Same issue losing root. But when I try to open Magisk manager app, it says "upgrade to full Magisk Manager to finish the setup. Download and install?" I click "OK". But the next time I try to open it, it just keeps doing the same thing.

I am not sure, but this may be because Magisk Manager is no longer..

How to Root OnePlus 8T Build 11.0.6.8.KB05AA

I previously had Magisk installed and rooted my 8T with Build 11.6.5.KB05AA. I followed some instructions on how to install an OTA update. I uninstalled Magisk and ran the OTA update. The instructions advise me to install Magisk on the inactive slot. However, I do not have this option. Instead, I only have Preserve AVB 2.0/dm-verify and Recovery Mode. I don't have TWRP installed so I don't think this will work. I've tried selecting Preserve and not selecting Preserve and selecting Next in Magisk. My next option is to "select and patch a file". I downloaded the bin for 11.0.6.8 and extracted it using payload_dumper and Python and copied it to my phone. However, whenever I try to patch it, Magisk states installation failed.
So, I figured I would finish the install of 11.0.6.8 and rebooted the phone using the update installation reboot button. I figured I'd just start from scratch and root following the original root instructions. My bootloader is already unlocked. I copied the boot.img from 11.0.6.8 to my phone and tried to patch using Magisk (again, I only have the options above). Again, it failed.
What am I doing wrong? Why won't Magisk patch the boot.img file? Shouldn't it work like an original attempt to root it?
Thanks.

I previously had Magisk installed and rooted my 8T with Build 11.6.5.KB05AA. I followed some instructions on how to install an OTA update. I uninstalled Magisk and ran the OTA update. The instructions advise me to install Magisk on the inactive slot. However, I do not have this option. Instead, I only have Preserve AVB 2.0/dm-verify and Recovery Mode. I don't have TWRP installed so I don't think this will work. I've tried selecting Preserve and not selecting Preserve and selecting Next in Magisk. My next option is to "select and patch a file". I downloaded the bin for 11.0.6.8 and extracted it using payload_dumper and Python and copied it to my phone. However, whenever I try to patch it, Magisk states installation failed.
So, I figured I would finish the install of 11.0.6.8 and rebooted the phone using the update installation reboot button. I figured I'd just start from scratch and root following the original root instructions. My bootloader is already unlocked. I copied the boot.img from 11.0.6.8 to my phone and tried to patch using Magisk (again, I only have the options above). Again, it failed.
What am I doing wrong? Why won't Magisk patch the boot.img file? Shouldn't it work like an original attempt to root it?
Thanks.

Make sure you download the latest canary magisk manager. It sound like you might be on an older magisk version.

I seem to have the Canary Update channel set already (I thought it was set to Stable, but I guess not). Doesn't that mean I already have the latest Canary build? Manager shows that latest is 6951d926 (21402) (16) but Installed shows 658d74e0 (21402) (16). I assume this means they are different? Install doesn't seem to update it. Maybe grab the latest APK from Github? Thanks.
Later: Can I install it on my phone by download Magisk v21.4 zip and changing extension to APK and installing it? I thought I read everything is now in the zip/apk? Thanks.
FINAL UPDATE: OK, I downloaded the latest MagiskManager, not the one from Canary. I was then able to patch the boot file. The phone rebooted, but it's not working just right yet. None of my icons show up on my home screen, although if I press the recent apps list, it shows a bunch of apps, although selecting one doesn't do anything. I might have to put the original boot image back on just to get it to boot and worry about rooting later. Sigh. It's always something.
Have you tried following this guide it should work perfectly

In the latest canary apk released today he moved over to that the apk bundle magisk as well and don't need to download it anymore but it shouldn't matter for this case. There is no working custom recovery for Oneplus 8T right now. But if there was and it was updated you would be able to flash the apk.
You did not have to uninstall Magisk. When you would complete the OTA, instead of rebooting you should go into Magisk and select install to inactive slot. As you uninstalled magisk, you're not getting this option. Uninstalling magisk is different from disabling the modules.
Now you need to root it again using the same method given in other thread. Rooting 11.0.6.8 is no different from the rooting process for previous OOS versions.

I was able to patch the new boot image and flashed it but when I rebooted nothing worked quite right. None of my apps would run. I could get into settings but couldn't get out of it. I flashed the unrooted boot image and am able to use the phone. I'll try again tomorrow.
The instructions I followed said to uninstall Magisk first. Now wish I hadn't. I suppose worse comes to worse I can figure out how to reinstall 6.5 cause I was able to root that. Thanks for the reply.

I was looking at a different guide, but will try the one you recommend. I'm aware there is no TWRP for the 8T. I did use that method for my prior OP6. I did patch and flash the patched boot image, but none of my apps appeared on my home page so I flashed the unrooted boot image so I could at least use the phone. Thanks.

The instructions definitely lied to you...
Now:
1. Take the 11.0.6.8 boot image
2. Patch it with magisk (latest beta is fine, you don't need alpha anymore)
3. Boot the patched image
4. Install magisk manager in case it's not installed
5. Check it for root, if all is fine do install --> direct install
6. Reboot

When you say Boot the patched image, I assume you mean fastboot flash it to the device?
I tried updating Magisk using a beta channel, but then manager wouldn't work at all. I just wouldn't run. So I reinstalled Manager 8.0.7 from the APK I downloaded and now I don't have Canary as an update channel. I keep alternative between having a Magisk icon and a separate manager icon. Weird. I'm trying to only wind up with latest manager installed so I can re-root the phone. Thanks.
LATER: Success! I followed the steps here: https://forum.xda-developers.com/t/guide-oneplus-8t-easy-root-for-all-unlocked-variants.4210775/. And everything worked (which was linked in a prior message). Thanks to all!

I figured out that's what you meant when I followed the instructions linked in another message. I had never booted that way previously. Thanks!
I am about to root my 8t using the guide someone linked above. My question is.. I'm on ver. 11.0.5.6.KB05AA will I still be able to root if I update or will it take away the ability to root.. also, will it affect the quality of the root ? Thanks in Advance.
