[Guide] Flash Magisk on Android 12

[jshbrmn]

There are other methods that will likely be developed and supported, but this one will remain an option for the finished version of 12.

Do this:
You don't need the Android flash tool. I have been manually flashing full images for a long time:
I don't like things done behing my back.

For beta 3:
I flash both sides hence the skip secondary - it saves a few seconds.
When flashing - watch what's scrolling by. The vbmeta.img is modified on the fly.
No need to copy from another build or someone else's hack.
Below is what I use. Successfully.

Modify the last line in the flash-all.bat or.sh
fastboot --skip-reboot --skip-secondary --disable-verity --disable-verification update image-redfin-spb3.210618.013.zip

Ach right, so you can pass the arguments to a fastboot update command and not just flashing vbmeta. Hoped so, but did not find a single hint on Google about it actually working. Haven't tried it yet though.

Do you think this will be necessary once the finished version of Android 12 is out?

Probably. How hard is it to modify flash-all.sh?
I apply the monthly updates myself, I always modify the shell script.

Keep --disable-verity --disable-verification in the fastboot command line. You don't need the others I'm showing, it's just how I approach updates. I flash the current slot, no reboot, change the slot, flash again. That way I flip flop slots each month. Just my OCD showing. The --skip-secondary option is my preference when flashing both a and b slots. I'll reboot myself when finished.
I wouldn't recommend the --skip-secondary when only flashing the current slot.

fastboot --skip-reboot --skip-secondary --disable-verity --disable-verification update image-redfin-spb3.210618.013.zip

For those of you who don't have safetynet working, here.
All credit goes to @kdrag0n, I just modified the shell scripts for B3

Pull request done if you don't want my zip.

I did - you'll be good to go. And I have safetynet.
Google Pay is set up, no rejected cards, but I haven't made a purchase yet. Confidence is high.

Can this be installed over the official magisk app (canary) ?

Can this be installed over the official magisk app (canary) ?

Need to replace App to see Alpha channel (it's not John's).

I had no issues just installing app with Canary App installed; you can try. Others needed to uninstall it first (due to different signing keys?).

Nb. Data / modules / settings are not lost or affected simply by uninstalling App as they remain in /data/adb unless Uninstall (full) is run from App or recovery. PW

Tried it on a Pixel 4a 5G. I am on Android 12 beta 3, never disabled verity because I don't want to wipe it.

I still get the same error at boot : failed to load/verify ...

could I do this with ota?

No, I recommend a flash.

No, I recommend a flash.

Ah okay. Will this wipe my data? I'm trying to avoid wiping data

You may have to. Going with a flash from 11 to 12 may pose problems with stability if you don't wipe. There is an example command line a few posts up that show how to disable verity and the command line I displayed excludes the -w for wiping. You may get lucky and have a good running phone. You may run into issues. If you do you'll have to wipe. I fully recommend backing up your sdcard data before doing anything. Simply taking the ota or sideloading it will be fine until you apply magisk. Then you'll pull your hair out. If you do a full flash, modifying the last line in the flash.bat or sh as shown will give you success. Read up on fastboot and the command line options. As I stated in an earlier post I flash both a and b slots, then manually restart. That's what my example command line facilitates. Read up on switching the active slot as well. My command line isn't for everyone, it's how I flash. It's an example. If you do use my example, you must flash twice, once on the current slot, then on other.

Anyone has done the latest update and kept root ?

Full flash,as always. No wipee.

Full flash of the latest system image or the OTA only ?

I followed the process I posted on page 4 to move from 3 to 3.1 without issue....just to be clear:

- extract boot.img and vbmeta.img from downloaded beta of your relevant device
- add boot.img to phone (if downloaded, and extracted on another device)
- patch boot.img in magisk (i like to rename it to patched_magisk.img)
- move patched_magisk.img to desktop
- download and install latest beta from the OTA provided
- tap the reboot button on the OTA install screen once completed
- once the reboot begins and your screen turns black hit the power and volume down button to get into fastboot
- run
fastboot --disable-verity --disable-verification flash vbmeta path/to/vbmeta.img (you can drag img from location)
- then run
fastboot flash boot path/to/patched_magisk.img (you can drag img from location)

This has worked flawlessly, maintaining root while also keeping all my data.

This is only confirmed working from version to version (and subversion). I'd imagine it would work even while skipping a version, but it is untested.

My phone won't boot
it keeps going to fastboot

fastboot -w should fix your issue

 

[Eiad Ajam]

100% working

Easy update and root and keep your data

You can always update to the latest build and keep your data

Like the first time installation with more 1 step

1. Make sure USB-Debugging is enabled in developer-options and you have authorized the pc you're using on your phone.
   
   
2. Boot your phone into fastboot mode.
   You can do this by turning it off and then starting it by holding Power + Volume Down
   until fastboot mode appears or just adb reboot bootloader
   
   
3. Go here and click on the link for the Android Flash Tool.
   (I didn't copy the link directly so i don't have to update it everytime google releases a new update)
   
   
4. It should ask you to allow the website to access ADB Keys. Click Ok.
   If the website somehow doesn't work, try using Google Chrome.
   
   
5. Select your Pixel 5. If it's not showing up click add device.
   
   
6. Click on the edit symbol (pen) in the box where the selected build is shown.
   
   
7. Make sure Wipe Device, Disable Verity and Disable Verification are checked.

8. make sure Wipe Device , Lock Bootloader , Force Flash all Partitions are unchecked .​

9. Install and boot the phone when it's finished.

and finally Patch & flash boot.img

This is working perfectly with me
thank you
