Hi,
I wouldnt flash it by SEUS for 2 reasons:
First you have the best firmware available for the k750i. The newer firmware dont have megabass option and the volume has been decreased by one square.
Second, your CID will be updated.
I think its not being updated because your phone is BROWN

Change brown to red and Flash for any firmwere and ......... ENJOY :)
