Samsung E251 no service - GSM-Forum

Crls2k · 05-09-2011, 21:30

Hi, I have a Samsung E251 without network signal:

I flashed, restore defautl EEPROM from the site, and nothing happens...

I got the phone with this problem, client say that before it has network signal, but after he try to unlock (putting any !@#$%^&* codes) the imei set in 00000.....). So I custom repair the phone, IMEI now is Ok, but no signal!

BTW restoring default EEPROM from the site doesn't work, here are the logs:

Selected model: E251
Selected com port: COM2
Selected speed port: 921600
Please, connect phone and press shortly power button
Phone Detected
Sending loader1... OK
ARM version 3721
Sending loader2... OK
Flash ID: 00EC2206000100000024
timeout
Send NOR - fail
Elapsed time: 89 second, sw ver: 3.5.0015

But when I read and write phone EEPROM, everything is Ok but network signal is out anyway...

Any idea?? I don't think is hardware fail, also I read in the forum some reference to the same problem?

Somebody from Z3x Team please help me??

Thanks in advance...
