Hello there! Since I bought this phone I've always had sound problems while using camcorder. I used the first and, probably, the only method to fix it (change number ACDBID 545:2 to ACDBID 528:2), but it wasn't good enough. The sound was too quiet...
Finally I get the rom to work...
For clarification, here is what I did:
0. starting from CM based 4.4.4, rooted, UB
1. flash the official .ftf in flashmode
2. flash a kernel (boot.img) incl CWM recovery. I used this one: http://forum.xda-dev...
Remove battery, plug usb in PC, and back battery with press volume down.
