My phone does not want to install it. After the reboot TWRP starts, but once it reboots after THAT, FPOOS is not updated to the newest version.
I assume this is somewhat related to the manual TWRP update I made in between, to be able to back up my encrypted data…
Trying to follow these instructions TWRP complains that the zip file is not correct somehow (I’ll add the exact message when I encounter it hte next time 
)
