Best Cam Driver For W810i

[sannyo]

Hi! Maybe it isn`t the right place to post my message: anyone can tell me with FAR + SEFP before i upload the new cam driver i need to delete the old one (of course make a backup from the original) or just replace it...???

Edited: again a question :) i downloaded a few cam drivers and in a zip i found some verison to erom.. my erom is R3A005, but the package don`t contains it... ( have only to R2B001 and R1CA021) so if i install it can i make demage in my phone ??? or if the cam don`t works just change the cam driver with the original ???

thx to all
Alex
