Check the imei status via *#0011# At the bottom if it shows "NG" = No Good, well then it's no good lol This can be usually fixed by writing a good cert then reflashing the phone with a full stock firmware, and factory resetting it. At the bottom if it shows "MIPI Test" = Fail, well then it has failed This can be fixed by either an EFS reset or replacing the charging port (yes it can be caused by a faulty port board). If still not working then it's a main board issue, so replace the main board. Both of the above items have to be good/pass before you can get a signal. Finally make sure you run an online check on the repaired imei though all your carriers to make sure it's not blocked. If it's blocked, then try to repair it with a new clean one. You can check your current imei via *#06# Good luck. Last edited by BillA; 03-26-2019 at 20:49. | |
