Hi,

what version of firmware are you using ?
What is the path to the root-ifs.img (int the firmware) you dumped on your previous post ?

MHIG_EU_AU_P1531/MMX1/mifs-stage1/40/default/mifs-stage1.img
MHIG_EU_AU_P1531/MMX1/mifs-stage2/40/default/mifs-stage2.img

but the problem is probably the signature block at the and of the metafile
seems to me like a rsa signature
probably it is the metafileChecksum ...

Hi

i do not think the vin is in the eeprom
at least not in the eeprom of STG 5F

The vin is read from the car bus

but you are right - it has to be stored somewhere

maybe in the gateway EEPROM

does anybody know more ?

Well to clarify - we are talking about 3GP units ??

You changed 3GP Low (no HDD) to 3GP High (HDD) - right ?

Did you swap the control units in the middle of the car too ?
3GP Low has no Joystick button ?!?

Hi, this is what the GSM / UMTS Module Looks like.

Вложение umts-module2.jpg больше недоступно
if you open the unit - front side pointing to you -
it is located on the right side on the backside of the unit.
There is a small connector soldered to the board
where the module is plugged in.

Well, 56 is the radio unit RU
i did not change anything on that unit
if i swap main units MU (3gp <-> 3g)
sound changes from good to bad and vice versa

Du you really think there has to be done something on device 56 ?
B&O has its own amplifyer - it is device 47.
