Hi guys,
me again.
Could it be that the issue preventing the notebook to boot does not resides in the chip we are targeting?
Or it simply may be that I need to try another BIOS image?
Thank you.
Cheers

Hi guys,
I did manage to get a successful write!
Unfortunately though, the laptop is still in the same situation, stuck in the "BIOS Self Healing backup progressing ...100%" screen 🤷♂️
A couple of notes:
- I had to use W25Q256JV chip type instead of 25R256JVEQ ... maybe this in an issue?
- I used flashrom that for W25Q256JV_Q has only an untested state
.... still that the write succeeded 🤔

Hi,
thank you so much!
I did a first attempt to flash the BIOS file, the tool reported back an error, but I tried to boot up the laptop anyway.
The result is that he did something different than before: "reading ME Firmware" ... but now it ended up in the same "BIOS Self Healing backup progressing ...100%" state.
I will try later to flash it again.
See attachment for details if curious.
Cheer,

Hi guys!
With the right clip I managed to read the chip consistently, so here what I extracted.
binwalk shows some content, which is promising I think.

Yeah, I think my SOIC8 clip is not the right one.
Now I ordered a WSON8 tester which should be better.
Talk to you soon.

Hi,
I managed to read something from the chip using the following:
[B]sudo ./flashrom --programmer ch341a_spi -c W25Q256JV_Q -r backup.bin[/B]
I read it twice and I got a 32MB file but the md5sum is different between the 2.
I don't know if this is "normal" or the connection to the chip (is situ with a SOIC8 clamp) is not stable enough...
I attach the 2 extracted files.
Thanks a lot.
Cheers,

I'm using "flashrom" ([url]https://www.flashrom.org/[/url]) on a Linux OS with the CH341a programmer.
I need to check NeoProgrammer ....

Do you have any suggestion about programmer+software that can read&write a 25R256JVEQ chip?
Thank you,

Hi, thanks.
Unfortunately it looks like with my CH341a programmer and flashrom I can not read this chip 🤔
I need to understand if this is supported or not

Lenovo x1 nano gen 1 -- bricked -- where to flash the bios/fw
Hello!
A few days ago I bricked my Lenovo x1 nano gen 1 while updating the bios/fw from linux.
No the machine power up, but it stuck in a recovery state and I can not do much.
Lenovo X1 Nano Gen 1
Type: 20UN - X021US
S/N: R9 - 10W2D9
I would like to flash a new BIOS/FW on the chip using a CH341a programmer but ... I actually don't know which "chip" on the motherboard to target 🤦♂️
So here I am to ask for help.
I opened the laptop and I found a chip that may be the target, on it I've:
