Hp ProBook 470 G5 - Invalid Feature Byte - CRC failed

Model: Hp ProBook 470 G5
Motherboard: Quanta X8C, DA0X8CMB6E0, Rev: E
*******************************************************
Hello!
At the laptop mentioned above, the BIOS was corrupted. I reflashed the BIOS chip with a dump extracted from the manufacturer's website. After that the machine works, but I need to enter the DMI data to the new BIOS:

I couldn't find the DMI data in the old (original) BIOS, so I got them from the Hp "partsurfer" website by entering the machine's serial number.

The "Product Family" number was already factory entered and I managed to successfully entered all the other DMI data, except the "Feature Byte".
I can type "Feature Byte" into the field, but when I want to confirm it, I get the error "Invalid Feature Byte - CRC failed":

I double-checked that I didn't make up a typo while entering the number (including upper and lower case letters).
Any idea why it throws me the mentioned error?

I checked the entered "Build ID", "Serial Number", "SKU Number" and "System Board CT Number" one more time and I didn't find a typo.
I tried to enter the "Feature Byte" again, there is also no typo.

Yes, I have the whole machine and I'm probably the first one who opened it (excluded the RAM/HDD cover).
I checked all the stickers I could find, but I couldn't find the "Feature Byte" or "Build ID" on any of them.

No, there are no spaces in the "Feature Byte" I got from the Hp "partsurfer" website.

xamledyD ha scritto:Try to enter Feature Byte with extra spaces every fourth character, except the last five characters which you enter like "XX0.YY" (instead of 0 add space before dot).

The "Feature Byte" I got from the Hp "partsurfer" website has the following form: xxxxxxxxxxx#SBED#DBED
I don't know where exactly do you mean to add extra spaces.

xamledyD ha scritto:Have you tried updating BIOS to latest version

I updated the BIOS to the latest version now:

Unfortunately it throws the same error when I try to enter the "Feature Byte".
However after the BIOS update, a request for new DMI data appeared "SMBIOS UUID", which I don't know what to enter:

xamledyD ha scritto:and restore default settings?

I also reset the BIOS to the "Factory Defaults", but that didn't change anything.

And one more thing - I'm not sure about the "SKU number". I entered the "Product ID" number here (from the laptop bottom cover) without the "#BED" extension.
