Okay, I did it and it finally worked. Note that
- if you want to use FP2 OS over lineage, you have to wipe and format and stuff before running the batch-script
- the new FP2 OS refuses to connect to my WiFi, so I had to try again with fp2-gms-19.05.3-manual.
- lineage-16.0-20190819-microG-FP2.zip refused to connect to my WiFi as well. It just said “no internet”
So, now I have the older FP2 OS installed again, the freeze bug could be reproduced and this time I hope they’ll finally accept that they have to take it back.
