I have used the EasyInstaller and followed it’s instructions. I believe I didn’t do wipe cache/Dalvik as it wasn’t said by the EasyInstaller instructions.
I had few problems however during partition change (not sure what is it changing to)
repair or Change file system reported some red failed messages, so I looked at and did the part with exfat and ext4.
If red error messages show up, your phone is probably encypted but TWRP can’t decrypt the /data partition (it’s a common issue on Samsung phones).
Yes my phone was encrypted. Did I do that part wrong? Maybe, because it is not very clear what exactly should I do with exfat and ext4.
I can try it all again if you think it’s worth it…
