I have flashed my k550 to w610, So now I want to change acoustic and camera drivers
So, should i look for the ones for k550 or w610?
and tell me some good acoustics and camera drivers

the other problem is that how do i check if I have a DB2010 or DB2020 or anyother?

Plz.... Help!

Your phone is DB2020. And acoustics that are for W610 work on K550 in exactly the same way. And vice versa.

EDIT: That includes cam drivers too.

Should I use XS++ 3.1?

will u please guide me how to install the drivers?

and also do tell me which acoustic driver has the best quality?

Searching this forum can answer both those questions.
