HP 15-bs058nf Corrupted bios

[KoSLoW]

Hello,

I'm looking for the correct BIOS for my HP 15-bs058nf laptop.

The official update from HP bricked my system — the screen went black and I'm unable to recover it using a USB drive.

I extracted the BIOS files from the official InsydeFlash executable and ended up with the following files:

• 084D4.bin (8192 KB)
• 084D4.sig (1 KB)
• 0832D.bin (8192 KB)
• 0832D.sig (1 KB)
• 0832E.bin (8192 KB)
• 0832E.sig (1 KB)
• 08328.bin (8192 KB)
• 08328.sig (1 KB)
• 08445.bin (8192 KB)
• 08445.sig (1 KB)

Unfortunately, I didn't save the original BIOS because it was already corrupted by the update, so I erased the chip using my T48 programmer.

Here's what I've tried so far:

• 0832D.bin → no fan spinning, no boot
• 0832E.bin → no fan spinning, no boot
• 084D4.bin → no fan spinning, no boot

Can anyone help me identify the correct BIOS to flash?

Motherboard reference: CSL50/CSL52 LA-E791P Rev: 2.0
I use T48 programmer with Xgpro v12.88

Thanks in advance!

Try this bios.

SMDFlea Sorry for the late reply. I just flashed your BIOS and it works!!
However, I get an error at startup: "Manufacturing Programming Mode is in Unlock Mode."

I saw a video about using the HP BIOS Configuration Utility to fix this.
I checked the TXT file, and the SKU (part number) doesn't match the one I found on HP PartSurfer:
https://partsurfer.hp.com/?searchtext=CND808427S

In the TXT file I get: SKU Number: 2PW31EA#ABU
But on HP PartSurfer it shows: Product Number: 2MG02EA

or do you think i can try recovery usb key to attemp a perfect setting ? (The computer's battery is dead, which might be the reason the update failed.)

What should I do?

Huge thanks again for your help!!

Change the info in the config.txt , save it then lock MPM

Everything is working correctly now. Thank you for saving my BIOS. I've made a PayPal donation for a drink. Much appreciated! ✌🏻
