Samsung E251 no service

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...

same problem,please help

Post here log,according to your log it shows writing fail.
