Hi!
I downloaded it from another thread in this forum, but I don't remember exactly from which one.
The one posted previously by some gentleman in this thread was not working for me.
Good luck.
Cheers...

For the records, I managed to recover my X1 Nano using the attached bios firmware using flashrom
[B]sudo ./flashrom/builddir/flashrom --programmer ch341a_spi -c W25Q256JV_Q -w X1_Nano_Gen_1_Laptop_ThinkPad_-_Type_20UN.bin[/B]
Thank you for the support!

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.

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:
