Here's a full backup of the mmc on 3.3.1 (a3d24621e), because the full mmcblk0.bin file was 28GB I removed userdata.img and compressed it with 7z so it's only a 1,92GB file. I don't have any accounts on the device, so I'd be surprised if you somehow got any personal data from me.

Maybe you could flash everything?
I'm making a backup of my device now on 3.3.2 (991cdce0). If the the above doesn't work, I can factory reset it, boot Magisk (without flashing it) and make a full stock backup of the device, then restore my backup.
