Great ! Thank you ! It took some tries to program it right with my ch341, but it finaly succeed.
I was able to boot the laptop with this file .

There is still a major issue, that sometime it boot, and most of the time not: just some led are on, but no fan, no screen, no boot . I ll try to flash again once it start, but I suspect another issue.
Will see...

Hi guys,

TL;DR – I’m trying to get into electronics repairs and bought a couple broken laptops. A couple start but get into a short boot loop before Caps Lock becomes responsive.
Here’s one of the little troublemakers:

Make: Lenovo
Model: Legion 5 15ACH6H – Type 82JU
Motherboard: NM-D562 Rev 3.0
S/N: PF3D52R7
Bios Chip: Winbond W74M12JWZPIQ

Symptoms:
- Boot loop with no image.
- Esc+Caps Lock key LEDs lit, with Caps Lock unresponsive.
- Fans spin at the start of each loop.
- There’s voltage on every rail.
- No shorts that I could find, but not really an expert; just getting started.
- Pictures and exported BIOS attached; hope it helps.

Obs.:
- I went trough the guides and failed miserably both on Linux and Windows in my attempts to extract the correctly sized BIOS from the packager. I did try following the guide in the forum, which took me to a guide in Github, which led me to seek ChatGPT for extra help (and ended in a loop myself with the damn thing), all while a day and a half passed and the .bin is still not the correct size.

Attached () you’ll find:
- photos of the cursed board
- the .exe packager taken from Lenovo for my serial
- the decompressed.bin taken through Linux wih the “help” of ChatGPT
- the BIOS.fd I managed through Windows 11 (VM through Linux)

I’d love to understand the process, as I’d raher do the fishing myself than just eat he fish, but this one is driving me nuts as no instructions I’ve seen matched the straightforward result expected from following them. =/

Apologies for the wall of text. =)

post merged...next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread..

Thanks, qayyum786!

I faced two issues with the flash - first, flashrom didn't manage to backup two identical bins; which didn't bothered me since the laptop is currently in bricked state, so that bios wouldn't do me any good.

But, the worst part was the failure to flash the chip with the bios you provided. Any idea what could cause this? Is the chip itself damaged and the reason for the laptop to be bricked in the first place?

flashrom v1.6.0 (git:v1.6.0) on Linux 6.16.7-2-cachyos (x86_64)
flashrom is free software, get the source code at https://flashrom.org

Found Winbond flash chip "W25Q128.W" (16384 kB, SPI) on ch341a_spi.
Reading old flash chip contents... done.
Updating flash chip contents... Erase/write done from 0 to ffffff
Verifying flash... FAILED at 0x0004025e! Expected=0xfc, Found=0xec, failed byte count from 0x00000000-0x00ffffff: 0x3fc
Your flash chip is in an unknown state.

Sorry needed to order new clip to dump the 3 bios.
From now i do not know yes most of time the UB2 only got corrupted but some years i got a legion with the video bios and EC corrupted.
I tried the different UB2 available but none of them worked and my model is a 5600h 3070 with serial number different from the one available.
🤦♂️ sorry for new thread "post merged...next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread"
Thanks
