GM CD70 Navi. Divorce

[bank]

Hi guys!

I have paired CD70 + CID.
I read out CarPass from CID, it's 3936.
Please help with divorcing CD70.
Here is a dump (https://mega.nz/#!FCYF2RYC!F3PMqKHdiT0871Vr7DynmELw_P4hKnme-HBHRwEtQqY)
As I understand using OpCom I can pair it again with 3936 and then unpair

Cd70 dies. :( It works only 10-15sec after plugging in. Then it disables.
I can do everything with it (even unpair) but during a short time (during it works after re-plugging).
Also, now it has "replace ecu" error.
Any ideas how to fix it?

After disabling during 15sec fan stays working, it can take and eject CD's without playing music, and there is no any communication with EHU after it disables

You change only eeprom from bottom? In these radio there are two 24C64, if you want to divorce you need to change eeprom from bottom only. Do you try to programm radio via original dump? There was 3936 code.

I change only bottom eeprom, I've successfully program radio with 3936 code and then successfully unpair. But, I was doing it quickly, in 10-15sec interval. Something blocks device after short time working. It was working normally before dump was changed

Hi guys! I solve my problem.
The root cause was in programmer EZP2010, which, as I understand incorrectly read or write a part of dump.
I took another programmer and write a dump of the same unmarried UHU. And it helped me to return to life EHU.
