Indeed, I was thinking on what I had done back in the day, since I try to be as safe as possible in these things, my bad for not saying it .MagiskHide on for SafetyNet - yes
Hidden / renamed Manager - not necessarily
Easiest / least fraught way to recover device:
If you did 'nandroid' backup (Twrp backup) of partitions before you rooted, simply do TWRP Restore of boot partition. (If you ever tried Direct Install with Recovery mode selected -should NOT be used on your device - you may need to restore recovery also, or just reflash TWRP.)
Get ADB working on a PC
Download full ROM package from OEM.
flash from PC using 'fastboot flash boot boot.img' ADB command.
I have checked the phone and both PCs in which I know I did the rooting steps looking for any kind of backups, without avail. Only OEM version I found is 31.02, and then the subsecuent updates for the firmware, which only contains boot.img.p.
I'm not sure if I should try to just use the stock 31.02 boot.img, since I can't remember which firmware version I had before the bootloop (Yeah, I will never do this kind of stuff without writting everything down, learned it the hard way ...)
tusch00101 backups from the upgrading progress are sadly offline too. Would be safe to use the stock (31.02) boot.img with twrp recovery?
I still have the Magisk manager and Magisk .zip versions I used a year ago as last resort, although I would like to know if using current Magisk.apk renamed to Uninstall.zip on TWRP could help on fixing the bootloop in case the boot.img I have is risky to use, and if doing so what I would loose or have to be wary off (Deleted folders, OS overwriting recovery partition, etc) to prepare ahead.To re-root, ensure you have uninstalled ANY Magisk Manager or App (especially renamed instances). See release notes re changed hiding methods / incompatibly:
Try re-rooting with latest Magisk App. Recommend Patching Image method, but can rename apk to zip to flash from custom recovery.
In the (likely at present) event of issues with your device, re-flash UNPATCHED boot.img, download older (working) Magisk zip installer, and flash from TWRP. If Manager is not installed in that process, install the corresponding Manager for that build, not newer App.
Also, be sure to read official Installation Instruction page:
Thanks again for everything, I'm starting to see the light after the tunnel
