I changed my friend's K550 camera driver with camera driver mod by Chris and it ended up with camera didn't work at all.Each time I opened the camera,it said 'application is running'..I uploaded the original one and it didn't work too..The K550 has CID53 so I uploaded it by using JDFlasher coz XS++ didn't support it.Please I need help...Thanx.

A reflash will work.

But you sure you got an original camdriver? It should be fixed if it is original.

that message appears when no camdriver0.dat exist.

check the correct name for the file (camdriver0.dat)

and correct path ( IFS\SETTINGS\CAMERA )

Make sure the camera driver is 100% K550's camera driver and make sure it's not broken. i used to have a broken camera driver and when i open camera, i cannot open for the 2nd time till i restarted the phone

Yeah,I uploaded it into IFS/Settings/Camera n It's original K550i camera driver with the name "camdriver0.dat". I downloaded it from TopSony. It seemed weird coz If I restarted FarManager,the camdriver0.dat was missing in the phone FS. But I'm really sure that I've uploaded it there.
Can anyone give me your camdriver for your K550? Thanx for all the replies.

try this
k550 original camdriver... should work... give it a try... or why dont u try a w610i camdriver??

w610i cam driver

as i told you

If you have the Main & FS files in your hard drive, just make a full flash and finalize the phone, that's it! you'll have the original cam driver, acoustic etc... back in your phone!

Thanx for all the replies...U guys are really helping me.
