Device: OnePlus7, Android 10
What happened
Device was rooted with October security patch updated, custom kernel installed and Magisk Manager hidden (to prevent root detection by an app). All working fine. No problem.
Updated Magisk Manager to 8.0.3 successfully but it shows Magisk not installed
But device is properly rooted and all rooted apps work fine.
I can see the hidden Magisk Manager in app drawer but tapping it doesn't help. Nothing happens. It tries to open, shows Magisk logo and disappears.
I can't access the Manager menu to see if I can fix something from there.
What I tried
Flashed Magisk again from laptop. No use.
Restored stock kernel from backup made by kernel manager app. No use.
As suggested by Didgeridoohan's guide tried these
Cleared data of Manager. Uninstalled and installed Magisk Manager. No luck.
Uninstalled manager, installed canary manager and set channel to update to canary hoping that may help. Doesn't help.
Device still properly rooted
- Saw this Github issue, Not applicable.
Things to try
Flash Magisk uninstall zip and root again.
Try manual patching of boot image and flash
Dirty flash stock ROM - not possible because device is rooted and would result in boot loop.
Any other simpler option?
