ok, so you put the quick access. Now you need to put the unlock patch generated by my tool:
First generate an unlock patch. Run my tool, select the MAIN firmware(K800_R8BA024_MAIN_GENERIC_WI _RED52.mbn) and press Make patch button.
In SETool2 Lite select your phone type, tick 'Use "quick access" patch' checkbox, select the generated unlock patch(Remove_SIM_lock_K800_R8BA024.vkp) in Misc files and click Write SCRIPT button.
