[Guide] Root Pixel 5 with Magisk Android 12.1

[soCram]

I found a solution for my issue.

For the others out there suffering the same issue with a non-wiped phone:

I obviously did have some modules activated which still caused the phone to bootloop even with patched boot.img and Magisk 23016. This is problematic because even flashing the current patched boot.img does not help here (even if you uninstall the magisk manager first). Magisk is still loading the modules which are causing a bootloop here.

You have to do the following in this case: flash the patched boot.img and start in safe mode. The, run adb shell and enter "magisk --remove-modules". This will remove the modules and reboot your phone. The phone will then boot flawlessly.

Edit: Just saw your post @Homeboy76: Thanks.

Maybe it makes sense to give this hint on the first page to people which updated to Android 12 some time ago and didn't get root after the update and are now using the opporunity to root with the new Magisk version?

Did you dirty flash Android 12, removed the -w from the flash-all.bat file?

Did you have Magisk installed with Android 11?

Were you on the Android 11 Stock Factory image or a Custom ROM before you upgraded to Android 12?

Did you disable/remove the Magisk Modules and unhide Magisk if you hid it before you upgraded to Android 12?

Assuming your bootloader is unlocked and you are using the correct version of SDK Platform-tools r. 31.0.3 and Magisk Canary 23016 is, currently, installed?

Try:
- Boot Safe mode, when it is fully booted Reboot
- Delete all magisk_patched.img
- repatch the boot.img for your Factory image
- flash the new repatched magisk_patched.img

If it doesn't work without bootlooping. I Suggest you flash the January 2022 factory image with the -w (Wipe) and start fresh.

You said January 2022? But you meant December 2021 correct?

You should be able to remove all the Magisk modules through the app without issue you just have to reboot your phone once you remove the modules and then un-hide Magisk and reboot and then remove Magisk and reboot and do it all from within the Magisk app.

Nope! I am referring to the next Factory Image update. We, currently, have the December 2021 Factory Image installed

I tried that but it didn't show me any modules there.

Okay I understand why you said it like that now.

That's strange

After typing in the command "fastboot flash boot --slot all boot.img" it's stuck on <waiting for lot>

The "waiting for lot" error occurred because you typed a single hyphen (-) in the slot all command instead of a dash/double hyphen (--) before the slot all. Thus the command should be written "fastboot flash boot –slot all boot.img" and not "fastboot flash boot -slot all boot.img" I could not find this error addressed elsewhere on XDA.

Between keep data or wipe data which option allows us to retain root when the new update comes?

please advice

Neither, please note the last comment of the Keep data and the Wipe data are the same:
• Go-to Root/Reroot with Magisk and Pass SafetyNet, •Patching the boot.img - to root/reroot.

Do Keep data to update the factory image. Then flash the magisk_patched...img, if you want to root/re-root your phone. It only takes a few seconds to flash the magisk_patched...img).
fastboot flash boot magisk_patched...img

Do Keep data then flash the magisk_patched...img. It only takes a few seconds to flash the magisk_patched...img).
fastboot flash boot magisk_patched...img

Not sure I am following. If I just want to update when the next android update is available, a re-root is needed?

 

[Homeboy76]

If you just want to update, your device, you have two options:
- Take the OTA
- Do Install/Update Factory Image Keep data or wipe data: To update the factory image.

Both options will remove root.

If you want root, yes you have to root/re-root.

I've read the original post but I'm still confused. If I take the OTA I do not lose root, right? And which is the method I use to download it?

He clearly stated Neither
In other words, you will lose root

Quote for reference:

Updating will always "lose" root, because the boot image is overwritten with the (new) unpatched boot image.

Fortunately, it's extremely simple to regain root: just perform the update however you want to do it, then patch the new boot image with Magisk Canary 23016 or later.

For the sake of clarity, we no longer have to worry about losing the ability to root. Magisk 23016 fixed this.

Try Settings Apps => See all => Google play store => Storage & cache => Clear cache and Clear storage => Reboot.

Ok, that's fine. But here is what I am struggling to understand that the guide is not clear on:
1) When I want to simply update my phone, what is the difference between a factory update/OTA update?
2) If I do the OTA update, can I download it directly onto the phone and run it on the phone, or does it need to be on the computer?
3) Once the OTA update is applied, do I then proceed with patching the boot image and editing the flash-all.bat file?

If you do the OTA update, you can download it directly onto the phone and run it on the phone.

Once the OTA update is applied, you then proceed with patching the boot image if you want to root your phone.

Notes:
- The boot.img you need to patch is in the Factory image file.
- Use Magisk- Canary to patch it.
