[mitxi]

Hi, I’m trying to recovery de BIOS on a bricked notebook, because doesn’t boot and
BIOS don’t save changes.

The BIOS download file is:

https://download.lenovo.com/consumer/mob...cn21ww.exe

With Phoenix tool I don’t found the file name. I try UEFITool_A45 and search for
.bin and .fd and only found isflash.bin but no lucky.

My current bios version is c2cn19ww (v2.00)

File names that I’m write too:

WinAIWZ0202.bin
AIWZ0202.bin
AIWZ0.bin
BAIWZ0.bin
C2_Crisis.bin
isflash.bin

and some others forms with .fd, and .rom

Thank you by your help.

Hi
try
Broadwell.fd

Thanks for your reply.
Sorry, I forget to write that name.  It not worked, but I’m trying a second time, in
all usb ports.

I have a 512 Mb pen drive, fat32 formatted. I’ll post the results..

Finally I bought a SPI Programmer (MiniPro model) + SOIC8 Clips (Pomona).

I'd flashed bios ROM, but the latest Lenovo's version C2CN21W (2.02) doesn't work.
(Blank screen and not boot)

I try a old ROM (Ver. 1.0) that I found in another web forum
(https://www.badcaps.net/forum/showthread.php?t=59939) and it works.

My bios chip was a Gigadevice (Model G25Q64C for the Minipro).
Now I have the notebook working again.

Thanks Dudu2002 by the hint.
