I was using iphone 102, i upgraded it to 111 following a procedure i found in the internet. I was able to upgrade it to 111, now it is 111, but the problem is that it is not giving signal. I put it to recovery mode then tried to restore, iTunes just gives me error messages. Now my iPhone is on the "Activate iPhone" state and the keypad is not working, if i click on the (i), it shows unkown IMEI and ICCID. What should i do? Please somebody help me. Hoping for somebody to reply, THanks in advance.
