hi
i had that problem,you must flash new camdrive to your phone.
try to do it with setools2lite
QUOTE
i used xs++ to transfer original cam driver no need to flash, worked for me
but i guess some people might have water damage, but its worth a try
and its free, just find original cam driver for you phone.

i had similar error message with my k610i, i reinstalled original camera drivers with xs++ that fixed it, i messed it up by installing newer third party cam drivers etc to improve picture clarity etc etc.
