I updated to kitkat 4.4.4 last night this morning I noticed that my note 3 was not finding the sim card. I have tried repairing many times but with no luck. Its a verizon Note 3 but currently using it in Mexico. Is it possible to downgrade to 4.4.2? or root it to sim unlock? or can I buy a code? HELP. I am new to the android world (previous iPhone user). I cant afford to be without a phone. Is there any solution to get the phone to recognize and red my mexican sim card or have I bricked my note 3?
