Encrypt phone with FairPhone Open OS

[AnotherElk]

Trying to encrypt with Fairphone Open OS 17.02.
After starting the encryption an Android picture was shown, then the phone rebooted immediately and is now showing the flashing “LOADING” since approx. 3 hours …
I would guess that the phone is not encrypting, or is it?

Edit: Took the battery out, put it in again and started the phone, seems like nothing happened.

Edit:

Or, even simpler:

Boot into recovery
Select ‘Wipe’
Select ‘Advanced Wipe’
Select data partition
Select ‘Resize’

This automatically resizes the partition to the correct number of 4KB blocks.

Thanks @sil-van, that did the trick … now on to struggling with an unresponsive touchscreen …

Edit: Ok, checked this touchscreen thread and it seems my charger is causing the touchscreen issue … but only after encrypting the phone … This feels like an adventure game, I don’t know whether I like this gamification trend nowadays …
