Have you read thru the thread ? What phone are you using ? If you do it correctly, it only takes 15 minutes to replace acoustic driver for w810i.
yap..but still cant fix my prob..i use w700i..
let me teach you... its easy.. it just took me less than a minute to change the acoustic.
1st.. download the XS++(XS2 i dont know whther it will work or not)
2nd.. download the acoustic that u desire..and usb flash driver...
3rd.. when u install@extract the xs++, in the folder u will see there will be a folder name files_to_upload
4th.. in the folder files to upload, u create new folder and it should be like this.. files_to_upload/ifs/settings/acoustic/
in the acoustic folder, put the new sound driver@acoustic in it..
5th.. connect ur phone while holding 'c' button.... later you will be ask for driver and install it using the usb flash driver...
6th.. when ur phone is connected... there will be an option name FSX.. click on it, and u will find that there are button to start uploading.. click on it.. start uploading.. and its done.. easy as that.. no bruteforcing and no flashing your main.. i figured out this by myself as my phone is w810i cid49 brown.
if u still confuse.. just ask..
may this be helpful
