I have flashed several custom roms with 4EXT as well as the stock ICS file with no luck..
When i try and search for network operators i just get a message that says "Error while searching for networks"...
Any help would or input would be greatly appreciated as i have now spent a few days trying to get this phone to work again.
"I have had this issue twice ... first time it happened maybe 9 months ago and stayed like that for 3 weeks with me constantly flashing and wiping and s-offing no no avail ... one day I pulled out my sim and memory card and when I switched on the device it says "no simcard" it never said that b4 so I switched it off and put back in the sim card and memory card and poof it was suddenly working again...
The first time I recalled not installing anything for months before that event other than one app..... "What's App" I installed what's app and used it fine for 2 weeks and the phone just dropped in the middle of a call and never regained signal.... so I said since that was the only app that I had installed its probably the culprit, so I will never use it again since the phone started working again.
Sadly 7 months later a girl i was talking to kept insisting that I install whats app because she wants to chat more... Against my better judgement I went ahead and did it and it worked for 2 weeks and one morning .... poof "no service" no imei .... and the culprit .....? WHATS APP!!! sadly I have been in this state for a month now with no sign of it fixing itself again... thank you whatsapp... let me know if whatsapp was installed prior to your loss of imei"
