problem in 6150 2nd Eeprom Checksum
 

I've 6150 i changed th IMEI by wrong with Twister and after that IT'S become Contact Service I'try to change Imei Back but no way when i use Eeprom Tools i Found the orignal Imei is different from the Imei i try full flash and dejan Twister to flash but it's still contact service when i ceck it by self test i got that 2nd Eeprom Check sum Faild i try to change the IC under CCount but it's still the same Imei i change the flash which "INTEL" but it's still the old Imei please help me to find the solution to solve this problem :confused:

make this algorithm:
1-flash the phone with full flash.
2-try eeprom tool program.
if not

Try other program as ddp to change serial number.
if the serial isn't adjusted there's problem in eeprom ic(HW fault).
