	DBox read-only? « on: July 06, 2017, 02:35:29 AM »

Hi,
I have a DBox ECU, where obviously a new 29F800 with a tune was soldered in. I was able to read the ECU via MPPS and Galletto Bootmode.

When I try to write a stock MBox file on it, Galletto1260 and V54 showing writing error at 0%. MPPS and Kess are also not able to write.

Could it be, that the soldered flash has some kind of write protection?

Regards,
Patrick

By d-box I assume you mean 8D0907551D?

If so, nothing on the flash can prevent boot mode flashing from working, unless somebody physically lifted the write pin.

Yes, Euro S4 8D0907551D

which one is the write pin?
Could the EEPROM prevent bootmode flashing?

@marty, I tried bootmode on my desk. Reading works, writing not...

The Chip does not seem to be 29f800 but PA28F800. Could this be the reason?

Should be fine unless it is defective or on a riser (obviously).

Yes, it is exactly the same issue. Galletto says "Erasing...OK" and then "Writing...Error". Reading is still possible, so nothing is erased...
The Chip is not on a riser, but directly soldered.
