Please help me!
SIM don't work. :crying:
Does it say "Emergency calls Only" or is it blank??
If blank then try to search network in manual mode? Still no luck then you have to flash the latest .33 firmware.
Then flash either the CM11 zip or if you have Nandroid Backup then restore that.
Sorry can't help further.
Always remember after flashing a ROM and installing everything, adjusting all the setting, and performing all tweak take a Nandroid backup using your Recovery, its much easier than starting from scratch.
