Having trouble editing SPI ROM

[arghhh]

Trying to edit the SPI ROM in order to get the serial to match the case on a board I replaced. I have a TL866.

I used the read function in minipro and had to uncheck "Check ID" to get it to read. But when I dumped it into HxD and tried to find the serial, searching for "hwc" didn't pull it up and "c02" pulled up an invalid serial when I tried to verify it on everymac.

What am I doing wrong??

Here is the dump and what I did: https://drive.google.com/drive/folders/0BwIAaoowgCg6QmRFWnRUYkM5aG8?usp=sharing

Your file is not complete, it is only 2MB, it should be 8MB..................

Ok. Should I be leave "check ID" checked? Because it returns an error if I do.

 

[aprendiz]

which chip are you trying to read and what is the version of ythe software for TL866??

Stop messing with it if this is working. It will corrupt the checksum, although this has no apparent effect on operation it will fail ASD.
Who cares the serial does not match.

25L6406E... Fail. Thanks.

It has to go back to Apple because the anti glare is coming off, otherwise I wouldn't bother.

If you mess with it it will certainly fail AST and will be denied. I have never had issues with the case not matching the board. As long as the LCD is original to the board as the LCD serial is also stored in BIOS.
How old is this machine?

Leave it alone if the board and LCD are original. It WILL fail AST if you edit the serial and will be denied.

OK thanks, appreciate the info
