Hey friends i am new to TOP SONY and i have a problem. I have a K750i RED CID49 phone. I had R1CA021 and i foolishly updated it to R1DB001 using SEUS. Now the Mp3 quality sucks!! I can flash to W800i but i'll lose the ACTIVITY menu and i dont want to. So is there any way to revert my phone's audio quality and retain the ACTIVITY menu? Can acoustic profiles help? If yes then what is the procedure? Please help me guyz...
