But I can't read flash. Same problem I have with original ECU that came with car (BEX)

Both ECU-s are IMMO off. Also I tryed on an bench with no success

Galleto give me change speed error

I put video im first post. Ignoring waring and still won't read ECU.
When this ECU was on ATW flash, I could read it with galleto without problems.
But now when BEX flash is in it I can't read it.
Same is with BEX original ECU.
Maybe some protection, so it can only read via boot mode

Did you meam,someone else's file like from some tuning company??  I am using this file, found on this forum

you should be able to read in bootmode if a riser chip isn't on the board(maybe you can with some)
you can read with 800 memory method even if the flash is a 400 considering you just split the flash in half with a hex editor because all it does is duplicate the flash.
