Microcar Ligier JS50L BSI problem

[matekhr]

Hi,
I have a problem with a microcar Ligier JS50 BSI with 9C08DZ60 MCU.
I need to increase the mileage from about 5480 km to 8200 - 8500 km, so I read the eeprom area with UPA. My dump is attached.
At first I was able to verify the dump successfully, but later it started having 1 - 3 random verification errors in the hex range 74 to 86 (addresses 74, 76 and 86 in various combinations).
Then I made a fatal mistake - I tried to write the same dump back. UPA starts writing and always stops at address hex 71. The rest of the eeprom area is erased (filled with FF) and I cannot write it.
And that's not the worst - the entire flash space is empty (FFs) and I don't have a backup.
Can someone help me with the flash file and a suggestion how to restore the flash and eeprom?
I also need an eeprom file with about 8500km.
Just to mention, my UPA-UUSP has never failed before.


Any help will be greatly appreciated.

Huh, I'm running out of time. I believe someone have 9C08DZ60 flash backup....

Here are my updates:
Luckily, I was able to find needed flash file on the other forum, and it helped me to revive my BSI.
@perukeyservice: the file you posted is eeprom, not a flash file. But thank you very much, I used it to compare with my eeprom file (see the first post) to try to understand what bytes are to be changed.
My UPA programmer, as well as Orange5 are both working good, because I was able to write back my original eeprom file with both of them.

BUT (now comes the tricky part):
Addresses $70 - $79 and $80 - $89 only accept zeros or original values (?)
Any other hex value returns an error, both with UPA and Orange5 programmer.
Maybe because I'm trying to program it in-circuit? (I really wouldn't desolder a small 64-pin MCU)
