paul thank you to tell me the right procedure
but my question original was another....
i mean the "literature"...what does it mean "swap file" and what this operation do teorically
thank you in advance

If you mean byte swop, then take a hex string eg.

AB 3D FB 35

swop bytes would be

3D AB 35 FB

so swop file mean reverse 2 couple of numbers...
ok
but...why this? and what do this?

it means reserves the whole file like that.

if you want to know more google big endian little endian

ok i saw now what mean swap file and different ways...but....
why i have to make a swap?
why eeprom don't have to be programmed exactly in the same way as it was read?

When a file is swap the transponder entered data are quite different.

Example

OK = 00 11 22 33 44 55 66 77 88 99 AA BB CC DD EE FF
SWAP = 11 00 33 22 55 44 77 66 99 88 BB AA DD CC FF EE

ok thank you
but... why file is swap? this is my question and why eeprom read data well anyway?
i no understand the sense of swaping...sorry....

google big endian little endian and learn why if you want to put the time in to understand else dont worry about it

[Belloriccoefamoso]

i saw on google i saw but i didn't understand well
maybe i'm too stupid to understand
i would know why swap, why on immo eeprom and why my file didn't work, just to solve in future alone
just to understand, to solve myself problems...
thank you anyway

There are two types write data (big endian and little endian). The programmer does not know which type is used. You need to know looking at the dump when you need to replace bytes.

The programmer always reads and writes in one of these systems.
UPA reads fine. GQ USB Universal Programmer doing swaps.

When there is a problem, it is good to read fault codes BSI. When there is a problem with the EEPROM (soldering) do not log in pin code, no keys, no VIN number, and so on.

i have seen a problem like this before there was a broken key taped up to theb aerial so writing new keys in didnt work because it didnt recognise the old key taped to the aerial

the only thing i can see different is the key number it should have stayed as 2 not 8

in the dumps posted the bytes need swopping
