Yes after I posted my last reply I realised my stupidity and it is now unlocked, however the k800i have developed a problem, the backlight stays on while your using it from switching on but after it goes into standby the backlight does not come on through normal key pressing, and its a case of switching on and off to get the backlight back on. Is this a hardware or firmware problem.

The firmware I used during the unlock process was K800_R1JC002_MAIN_GENERIC_WI_RED52

Anybody got any ideas.?
