You said you have CID52, but I see CID53. You can't flash CID52 firmware on a CID53 phone. Try :
C510_R1FA035_MAIN_GENERIC_KT_RED53
C510_R1FA035_FS_ADRIATIC_RED53 and customize with
C905_1209-4776_R6A_GENERIC_ADRIATIC (you must add the MAIN, then FS, then the .zip file to "MISC files" and make "one move" flash)
