Where do I find BIOS firmware for HP 15-bs1xx?

[zennith]

Howdy!

I ran into BIOS updating issues a while ago and in which resulted in bricked BIOS. The BIOS chip was flashed with some compatible generic BIOS in order for PC to boot again.

These are my specs or at least what used to be

These are the current specs

I'm looking for BIOS firmware for HP 15-bs1xx and I only can find firmware for HP 15-bs100 in the drivers page https://support.hp.com/ph-en/drivers/laptops

I want to rollback to f.34 because of TPM 2.0 issues (Doesn't appear) or some other that may work better, but also don't brick my system.

Please, help!

If remember correctly, the latest BIOS firmware version on the shared link is the one whom bricked my BIOS chip. In this case I'm trying to install the closest BIOS version I had (f.34), but the update tool says the BIOS update isn't compatible with device.

Motherboard additional info

BIOS firmware f.34 bin files

Is baseboard product and motherboard id the same thing? If so, I can't find the matching ID on the bin files. If I could find the matching ID maybe I'd try to update/rollback BIOS using HP Hardware Diagnostic UEFI.
