After installing the 8901.4.A.0013.4 update, I’m unable to regain root through the Magisk method. Using the stock rom, no matter what Magisk Manager version I use, it shows “installed: N/A” and the only method shown is “select a file and patch”. However, even after patching the boot.img with Magisk and flashing it, the status “installed: N/A” doesn’t change and I do not gain root access.
By reverting back to to 4.A.0010 and doing the the whole “patch boot.img with magisk and flash it”-procedure, I can get root access again.
Did anybody manage to get root with Magisk under A.0013.4?
Edit: I have also carefully checked all the A/B slot possibilities and that I was always using the slot with the patched boot.img or installed it on both slots.
