with which tool you have read and written?

[crteam]

Galletto v53 never a problem before

[leandro89]

you read in the bdm?

[crteam]

You read in the bdm

hello
maybe I should have it at work tomorrow guqrdo and I try to post it

the problem lies in the checksum that is definitely the cock in the phase of writing calculates evil, the flash you read individually, or you have a bachup of the ecu?

mo I know caxxi look here what he says evc when I know loads the file:
Question:
In the BDM project doesn't have an EEprom element / WinOLS message 'Virtual EEprom found'

Answer:
Normally the date, which changes very often, is stored in an EEprom. These kind of memories have the special property that it must not be erase to write a new value into it. The old value can simply be overwritten. That is especially important at the immobilizer. Some manufacturer use 'rolling codes', which changes, for example after every 10th starting process.
Now some manufacturer like Mercedes leave out this EEprom and simulate this function in the flash eprom. Therefore a special memory area is defined, which is much larger than the EEprom space. At first the EEprom contents is programmed at the start of this area. If something changes, the new contents is programmed behind the first one. This is done until the whole space is filled. Then the whole area is erased and the new contents is programmed at the beginning again.

For the tuner, the problem appears, that a readout original file is possibly not valid any more after the next starting of the engine, because the data in the flash eprom has changed.

Valid is always the last file, which has successfully started the engine !

the board of rewrite e2p more flash gold, and then try the starter otherwise serves a reprogramming with mb star

Check l I checked with ecm and goes bn and in writing, so I selected no to the calculation of the checksum. The bdm has only read the flash eeprom nn l read

quoto fully legendaryslave but perhaps a solution c'? forwards all let's be clear about the version of the file:
this is the HW 0281012435 SW 1037375626
or HW 0281012435 SW 1037505804
after you have determined the exact version let me know that you calculate the cecksum
