I have the anwser for you all gsm hacker.

How to change the imei that's not that easy but i have just cracked it i like this.

all you must have is a epprom programer for the chips and shematic for the pin on the chips in the phone :=)

step 1. the epprom dump have a imei change it.

Step 2. the flashprom have a imei wery hard to crack the adress to the imei security bytes but i did it

step 3. the MCU have a stored imei change it that area is wery hard to crack the security byten in imei area but i did it

step 4. in the MCU there is a area called RAM the ram checksum adress must be the same as the other checksum adress just correct them and you don't have to crack the security byt's there

after you have made all dos changes you have to upload the epprom dump's BUT do not power on your phone after that.....

Step 5. then you must download the flash dump from the phone in the flash dump you must find a stored imei and the security byte's for that is not hard to crack

Step 6. then upload the flash dump and correct the checksum not hard at all

Step 7. after that just power on your phone then the phone is 100% working and with a new imei number

Hi,
It's visible that you're talking about NSE.
If you check the Service Manual you'll see
that every hardware change should be supported with reprogramming. I think for change of the IMEI you have to reprogram serial eeprom and Cobba. The Flash chip is not immportant. Also you're talking about MCU RAM - maybe you mean the internal eeprom
or some redister, not RAM. MCU use that memory only when the phone is on and you can't store anything manual!
About this MCU internal eeprom - yes it keeps some phone info, but restoring factory defaults with WinTesla, clears the old values and creates new( after change of Cobba and the serial dump).

So, how did you manage to reprogram Cobba?

Regards

Hi,
All the answers are in the WinTesla DLL's. Reprogramming, Flashing and everything. So somebody, able to 'read' these files can say
how they doin' that. I can't.
