Thank you @philipp !
I under stand part 1 as to download and flash the new firmware for the baseband.
What I don’t get is step 2, what’s flashed there? “Fastboot” isn’t that part of a FW?
Reading through part 3 I sense one will loose all important data, basically doing a full wipe. So far so good, but while I have my personal data saved in my nextcloud instance, is there a way to migrate applications, settings?
Step 2 is flashing the ROM.
Fastboot is a tool for flashing ROMs on devices, which are running in fastboot mode.
As I used the flash_all.sh script here, every data was deleted. I wanted to do a clean install, so don’t forget to make a backup first.
It should also be possible to use the other script with keeping your data.
I have no experiences with backup and restore app data, as mentioned above, I did a clean install, including all apps and settings.
