Citroen C8 DTC erase history issue

Good day!
I have the following issue with my Citroen C8 with edc15c2. Service history shows 57 entries but 50 is maximum value. I'm unable to erase errors nor clean service history. Only configuring ecu erasing errors and service counter rise by one over the limit. Now its 57.
I've found that editing the eeprom file could help this. It's said that editing value at 154 cell will clear the service history.
I've read the eeprom in bootmode on the table, but I've doubts if it's correct. There is only ff's after 230 cell. Is it normal? Can I write this bin back?
Here's bin file.

It actually works. I've put 01 in place of 39 at 154 cell and errors history counter went 01.

Because 39 (Hex) = 57 (Dec)

Did you use my file?

I've done by myself at the time. I didn't rely on someone's help here actually. People hold their secrets tight.
