HP 250 G7 : Can I flash microcode only?

[castillofr]

Yes! But laptop rebooted automatically after a few minutes, I did not count how many exactly?!

Here is the folder of the Bios updater
https://mega.nz/file/gJQEWCZY#UWcczqLIog...XCpf5tr7xQ
I do not know how the app decrypt the bios file and add the .s12 file to allow the flash...
H20EZE can edit the decrypted bios [by choosing in the GUI "copy the files"] with new microcode but failed to flash it due to lack of this .s12 file. May be by generating a new .s12 file using the tools inside the folder then the flash will pass ?!
What do you think?
