HP 250 G9 6F1Z8EA

[Cicciotest]

Hi everyone,
Thanks for your wonderful forum. After a reboot for the update, my laptop wouldn't boot. I'm pretty sure the BIOS was corrupted during the update:
- HP 250 G9 6F1Z8EA
- SN cnd2362vfk
- PID 6f1z8ea#abz
- BID 08A1E (Seen on the BIOS page before doing any operation)
- Chip W25R128JVSN (i've chosed a W25Q128JV inside neoprogrammer with CH341A)

Now, upon startup, a blue window says "Manufacture programming mode is unlock mode," then another blue screen says there's no HDD inserted. If I enter the BIOS and then exit, saving or not saving, I get a black screen with a solid white line in the upper right corner.

I've already tried flashing the 08A1E.bin file extracted from the .exe file downloaded directly from the HP website. But nothing, it doesn't change anything. It seems to me that these files are missing some critical partition (ME, descriptor, rdata) or the flash isn't complete. Can you help me?

I'm attaching the original backup of my laptop (made before flashing the HP one) and the one extracted from the HP executable.

Hi peste thank you so much.
I've tried the 08A1E.bin that you sent to me that, actually, it's different from the one I downloaded. I compared them with a hex editor. So thanks for giving me the file. I flashed it now with the programmer.

However the laptop shuts down immediately with this file. I press the button, the power LED lights up, and then the laptop shuts down immediately.
What do you recommend I do? Flash another variant?

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

yes yes I have the ch341a, the clip is perfect and connected.
I made a mistake when copying the block with Hxd.
Now i modified the bios correctly to the offset you suggested, it is recognized and starts but the problem persists, the end is a black screen with a blue windows that say "BOOD DEVICE NOT FOUND"
Already tried different ssd, so I have to deduce that we have a problem with the southbridge.

thanks for help!!

Try version F.70, peste gave you F.06 when your old BIOS is F.69 (not listed on HP website, they skipped F.68 to F.70..., maybe only available via Win update)

Yeha, thanks, i've already tested more than one time 😂 the bios is (was) pretty OK, sems i have a serious problem with another hardware component, i think is the southbridge (intel chipset) becouse it do not reckognize the pcie line of storage and network too (wifi+BT mini sata component).
i'm stuck at boot with a blue windows that say "Bood device not found" but any ssd nvme i put, it do not reckognize it.
Only USB works for now.
So i tried to boot with a bootable USB stick with linux live and test many command line to check hardware and sems thre is no response to lspci, lspci | grep -i storage, lspci | grep -i network etc...
