Hey guys, i read my spare ecu (me7.5 4B0906018AA)yesterday and called the file "READ FROM SPARE 4B0906018AA STOCK.bin" i also read the EEprom 95040 using ARGDUBs tool to have both backup files if i would need them later.
Today i read the spare ecu again just to confirm that the first files i read yesterday are correct.

But to my surprise, as i compare the flash BIN file from yesterday with the files i read today they differ on every OTHER byte.
There seems to be a pattern, every OTHER byte is offset by 1.


ALL the files i read today are exactly the same. but the one from yesterday differs from all the others.
I have a chinese clone galetto v54 and i am not confident that it reads correctly.
I used bootmode k-line to read everytime.

Not offset, stuck low.

You're grounding a data bit. Possibly holding the bootmode pin low while reading?
