No ve do desolder a eprom from the board, the 24c64 , read same value from the original one and modify the new one values.
This is the single way

Сергей, я имел в виду считанного с другого радио тюнера, я купил блок в польше, но боюсь ехать с ним снимать защиту к офам.

TV tuner has CP too ?

[Audiadict]

from 640 to 680 Copy All.
TV tunner no CP.

[Vlasoff]

c 640 по 680 там нет CP..
тоже ищу по какому адресу CP в радио?

[Crash-100]

Че там искать, берешь два дампа и анализируешь.

[Vlasoff]

У меня есть два дампа радиоюнита но они с разным железом, один от Н52 другой от Н60, дампы очень разные..
Поделитесь в ЛС адресацией пожалуйста, надо радио поменять на более свежее.

Hello
Is anyone coud say if the eeprom is a TSSOP or SOIC ?
SOIC could be read with a clip
SSOP like eeprom MMI 3G or 3GP need to be desolder and put into a programmer ....

Due to the board design you cannot read the eeprom on board
When you power the reader it will provide power to the eeprom but that that is connected to vcc bus on the pbc so it will try to power other devices.
If you power the unit and try to read you will get bad data.
You will need to remove it. It was SOIC on all radios that i did till now.

Hello Congo
It is very nice to you for your response

I have read your post but do you think it very not possible ? When Audi dealer make the protection component the writing of the eeprom is done by OBD...So Is the VCC bus is blocked to program (and to read) this eeprom ?

PS : It is you who have done a tutorial PDF for upgrade MMI 1.6 in PDF ? good job
