Spirit:
SETool Lite still claims it's network locked,
Even if the phone is unlocked by patch, it will 'think' that the phone is locked, because it reads the locks info from GDFS but the patch alter the MAIN firmware. So it is absolutely a normal behavior.
and I can't used my sim
What is the error message do you get?

mba2431:
i test SIM_lock_remover patch generator for R4EC001 in k510, but it not work.
Please give us more details. SIM-lock Patch Generator is unable to generate the patch? What CID has your phone? Or SETool2 Lite gives you some error message?
