I really need help

I changed the acoustics in my k800i to the w850, and it all worked well, the volume was loud etc. But when I made a phone call I found out I couldn'e hear anyone. So I've downloaded and installed the original k800i acoustics and the phone calls work but now the volume of my ringtone and music is very quiet (even on full volume)
**please help**

the software info says R1ED001 CDA102511/100 if this helps

thank you

use any other acoustics driver, which are loud in both.

There is lot's for acoustic available which has louder and better sound quality. Try to search it.

you can flash FW , phone is original

The best way is to perform full flash and return to original, then add the files you want.
