Searching, no service, no sim

Yeah if your not expected I would tell you replace the logic board.

If you have any questions or concerns please comment below. Thank you!

If the "No SIM" message changes to "Searching", when you put your SIM card to your phone, there is a good chance to fix this problem.

Sometimes the SIM card just not connect to the SIM reader properly. Open up your phone, and gently push down the top of the SIM reader. If the phone find the network now, it is just a simple connection error. Remove the SIM card, bend the top of the SIM reader and put back the SIM card. The top of the SIM reader will push the SIM card to the pins of the reader.

If it not helps, try to change the charging block. The signal comes from the rear case, it goes through the charging block, and goes to the board. So if there is no signal and the sim connects to the sim reader probably, the faulty charging block is the problem. Sometimes the rear case faulty, but that is very rare.
