I have a K750 R1DB cid49 but i don't like this firmware.
It doesn't have camera zoom at 2mp.
It's acoustic and cam driver aren't good.
And also i want to move operator logo.

How can i patch this phone?
(Pls also write links..)

Why not flash it to a W800i?

Because i want to use "activity button"
When i do that i can't use it.

Any other help?

cid49 phones can't zoom in 2 mpx mode!
you want acoustic and camera drivers?? use xs or farmanager and replace them!
my recomandations:acoustic:hyper_t active beta
camera:sarmad 5.8

Thanks for your reply.
How can i install this drivers?
I used Far Manager with my "cid39 K750" but i don't know what to do with "cid49 K750".
