I’m starting this topic because I found it incredibly difficult to figure out what I was supposed to do to backup my Fairphone. All this talk of TWRP, adb etc got me really confused, when all I had to do was (I think):
Install adb tools on linux with:
sudo apt install adb fastboot
Run the following command:
sudo adb backup -apk -shared -all -f backup-file.adb
This creates a backup file which I assume I can then restore my phone from? Could someone please confirm that this is correct and I’m not missing something out. If it is the case, maybe creating a wiki for this would be useful? Apologies if there is one and I didn’t find it.
