Hey, I deleted all the partitions of the device before flashing. Did you try flashing again? Because I did not face any such problems. Sound is a bit quieter, but that's pretty much it.
Yes, I merged the 2 partitions and also installed the binary blobs... I've been using alternative ROMs for my Android devices for some years, so I know the drill. I even tried installing a couple times, but the issues persisted.
