Can't login into W10 after May '22 BIOS update to F13; also F14 update ID doesn't match Motherb. ID

[MorganeFRA]

Good afternoon,

On May 19th, 2022, as I was shutting down my HP Pavilion Gaming laptop (15-ec0004nf, running Windows 10), a BIOS update got installed on my laptop automatically, to version F.13 Rev.A.

When starting up my laptop again later that day, I found that, although Windows 10 booted, I couldn't login into my session anymore. My password (a locally-stored password) is not recognized by the system anymore; and a second login option using a PIN number (which I never used before) shows me the following message: "Your PIN is no longer available due to a change in security settings on this device."

Several attempts to flash the BIOS (by hitting the Windows+B keys while turning on the laptop) were unsuccessful.

1st question: from that point, what should I do to access my files again?

Perhaps I could try reverting to the previous version of the BIOS (F.12 Rev.A), or perhaps I could try installing the latest BIOS update (F.14 Rev.A). Therefore, I downloaded these two versions from the HP website onto USB sticks, to create "recovery USB flash drives".

When I tried to apply any of these to my laptop, I found that the file carried in the BIOS versions is named "086D4.bin" … which doesn't fit my system board's number (it's 86D5). Because of this difference, I did not apply any of these two BIOS versions.

2nd question: can I apply either of the BIOS versions (F.12 Rev. A; F.14 Rev.A) without endangering its integrity, in spite of the mismatch with the system board's number?

Thank you very much in advance. And nice Thursday to you!
