[HOWTO] Backup and Restore Data on Android Devices

I had TWRP on my FP2 and I guess the installation was easier back then, because now with my FP3+ I am struggling to install it.

Why do you want to install it? Just because you had it on the Fairphone 2? For your consideration …

@AnotherElk

on the Fairphone 3 you usually don’t install it, because installing it results in a changed boot partition, as there’s no recovery partition on A/B devices.
A changed boot partition breaks OTA updates when using Fairphone OS, and in case of using /e/ it will just get overwritten by /e/ updates with the LineageOS recovery (or future /e/ recovery) … so there’s not much sense in installing TWRP on the Fairphone 3, so the Fairphone 3 usually doesn’t have it in recovery mode.

Booting TWRP with fastboot works
