Just reflash MAIN R1CA021_CXC125952_EU_1_CL
K750_R1CA021_MAIN_EU_1_CL_RED49
You can use XS++ and DCU-60 cable to do this
After you flash MAIN, remove battery, put battery back, turn on phone, and enter "Unlock NCK" code manually
Press <**< (< means moving joystick left), and enter the NCK code given by the program
