Ohh how unfortunate. You might have two options:
1: Install the 1.6 OS Version with unified partition update.
2: Boot into recovery mode and perform a wipe data / factory reset.
I’m not sure if they work out alright. You might get some better help in the xda forum.
Again: Any bugs and feedback is best shared with the develloper in the xda thread (link see above) as Chris isnmost likely not active in this forum.
