[CLOSED] Android 12 Upgrade Discussion

[V0latyle]

Hi ! I'm on A12 november clean install & disable verity & verification Root magisk canary.
But after flash a mod I loose the root

For Root magisk again I do flash before the original boot image and restart to remove correctly the root.
But do flash disable verity & verification vmbeta before ?

And after restart install manager flash boot img. And on fastboot flash vmbeta disable verity & verification and flash boot img modified it's right ?
Thanks

There is a known issue where Magisk may "disconnect" from root in the kernel due to a signature mismatch; the way to avoid this is to perform "Complete Uninstall" within Magisk itself.

If root is lost because of a module or some other problem, there's no way to really clean up the Magisk installation so that root will work again, unless you perform a factory reset.

You do not have to reflash vbmeta if you're restoring the factory boot image. Vbmeta only needs to be flashed if you are updating.

Is anybody else getting prompts to update to Android 12 after they've already updated to Android 12?

Yeah, it just popped up on mine an hour ago.

Curious. ... Well I think I will wait on this before acting on it.

 

[kfhughes]

It's being reported in other places.

Some Google Pixel phones are being prompted to download the full Android 12 update again.

I'm currently on .003 and still get the update notification even after a clean install.

During the 11-->12 OTA, I managed to keep root by:
flash boot patched_image, reboot (FAIL)
boot patched_image, reboot (FAIL)
flash boot stock_image, reboot (OK, no root)
boot patched_image, reboot (ok, have root).
Following these steps with the Nov. OTA, the final step seems to silently fail and boot with the stock image (no root).
Is this the expected behavior and I'll have to gain root the hard way?

Yes. There is currently no way to be able to keep your data AND root after upgrading to Android 12....with the exception of booting the patched image for temporary root.

Thanks. Just to be clear, booting the patched image only worked once, and now fails to gain temporary root. For me, anyway...

Sorry to hear that, no idea why that might be happening.

Hello All -

Thank you @V0latyle for all your hard work for the community here. I have been running A11 rooted and had been pushing off upgrading to A12 for weeks / months (not sure) until last night I decided what the heck let me try to upgrade. BIG MISTAKE!

I spent hours last night trying to get A12 rooted on my device without a full wipe (which now I know from this thread isn't possible). I sideloaded the A12 OTA with platform tools and I mostly followed the instructions here to try to root it. I spent 3 hours got every error possible from corrupted, no boot image, to endless bootloop all to no avail. I tried patching with both Canary versions and stable versions of Magisk and even tried to do the temp boot into the Magisk patched which didn't work either. Thankfully I was able to rescue my device by using the flashall.bat without -w in an elevated command prompt (must "run as administrator" or doesn't work properly)

Currently I am on A12 without root and I don't want to hassle with clean wipe right now (no time or patience) and not so enthralled with the new look of A12 especially the quicksettings huge tiles.

My question now is what is the best and safest way to "downgrade" back to A11 and then re-root like I had before? I am thinking to just sideload the A11 OTA but figured I would post and ask here first.

Thanks!

The most foolproof way to downgrade would be with the Android Flash Tool. However, downgrading generally requires a wipe. You can try dirty flashing, but again, it's likely you're going to have to wipe your data anyway.

and @V0latyle I am willing to try any other "tricks" or ideas you may have...

The ideas I had were mainly for upgrading to Android 12 to see if there might be a way for someone to go from A11 > A12 > root without wiping data. So far nothing has worked though.

What do you recommend trying for dirty flashing? Sideload A11 OTA? or flash the full factory A11 image with flashall.bat and remove -w?

Thanks @V0latyle for all your sage advice. I was forced to do a full wipe to either get root working on Android 12 or to downgrade to Android 11. I went ahead and did a full backup and then wiped and used the Android flash tool to install Android 12 again. Now I have Android 12 with root. However, my safety net doesn't pass. I am going to have to search through the threads to see what I need to do about that... Any links handy?

Again, I recommend you use the Android Flash Tool.

Do not sideload the OTA to downgrade.

Latest Magisk Canary + Universal SafetyNet 2.2.0. It's working for me.
