No longer booting with Magisk installed

[user822]

Hi,

I have a rather odd problem:
My phone simply does not boot when Magisk is installed


Installed Magisk 20.0 on Stock 10.0.1-GM21BA a while ago and everything was fine.

Today it won't boot any more (stuck on the warning that my bootloader is unlocked, then bounces to fastboot)
As soon as I uninstall Magisk from TWRP it boots again
Then I Install Magisk 20.1 from TWRP, it does not boot.
Then I uninstall Magisk 20.1 from TWRP, it boots again
Then I flash the pre-patched boot image from here and it does not boot again
Then I flash the stock boot image from here and it boots again
I also tried installing Magisk without dm-verity (only forceencrypt), still not booting beyond unlock warning and fastboot

Does someone know what is going on with my phone
Can I root it without Magisk?

Thank you for any help

Try TWRP 70

Maybe you're on twrp v71... Try reverting to the older v70

had same problem.i reflashed stock and locked bootloader back to offical, andriod 10 lets twrp work but not masgik. i even used magisk manager to patch file and flashed that file to have no more root

Thanks for the ideas, did not fix it unfortunately
Guess I will stay without Magisk for now

do you have any modules hanging out?

https://xdaforums.com/apps/magisk/module-tool-magisk-manager-recovery-mode-t3693165

you could try that.

Hmm.
Try this with twrp v70
1. Boot to twrp
2. Flash the full a10.0.1 rom
3. Flash twrp v70
4. Reboot to twrp
5. Flash magisk v20.
Reboot
Thats what i do if something is wrong.. i always reflash a rom..

Re flashing a rom also saved my friend's phone..after flashing boot.img for rooting purposes..he always boot without a wifi. So we dirty flash a rom.first . Then using that same rom that we flashed.. we extrscted its boot.img then patched it with magisk. Then re flashed.. then boom.. its working now..
Reflashing the full a10.0.1 rom.solved the issue..

My idea here is that
Flash the rom..
Then using the rom that you just flashed..
Get its boot.img.. then patch it then flash it again.. it will now boot. I havent tried directly flashing a patched boot.img without reflashing the rom first..

I met the same problem this morning. Did the following thing to let phone boot with magisk.

1. install magisk 74
2. install Magisk-uninstaller-20200110.zip
3. reboot magisk
4. install magisk-v20.3.zip
5. boot system

do you mean in step 1, Magisk Manager v7.4.0

Did anyone figure out how to fix this issue? I have tmobile and after updating to 9.5.5 and installing magisk it works until I reboot again and then it hangs and goes to fastboot. I try to narrow down the problem and it happens after I install adaway maybe after I choose system less. Or after installing YouTubevanced. Idk what I'm doing

Did anyone find a fix to this ? I'm having the exact same issue.

Flashing magisk 20.4 gives a bootloop. Uninstalling via TWRP allows me to boot to system. No overlays no modules etc,everything uninstalled but still cant boot with magisk. Have I missed something? The only solution I can find is factory reset and begin again, which I can do but as a last resort.
