Hi. First Post .

I downloaded the official bios and programmed that with CH341A.
Now pc powers on for a second then off. Hopefully just incorrect image.

PC is Lenovo M710Q Type:10YC

try post #2...

Hey again.
Just a quick update, flashed the file above and still unfortunately not booting.
It basically powers on for 2 seconds, then off etc. This happens non stop. Left it like that for 5 minutes.
I flashed the original Chromium image back, and it boots straight to the Amazon log in screen without problems.
Any other ideas please?

Thanks again

look carefully on the board, do you have two bios chips? or one?

Re: M710q Please my bios clean me

I believe I have the same issue as Psychomaniac, I have a M710Q 10YC, but the motherboard is the IX2QIH v1.1 (and not the v1.0 that others have), so yes, I believe it has 2 BIOS chips, a Winbond and an MX25L12873F.

When I flash the MX25 with the modded file from step 2 in this thread, I just get a black screen when powered on. Flash back to original BIOS and Amazon Chromium comes back on.

Sounds like there is a 2nd chip to flash with this model? Should I post the Winbond file? Let me know what I can do and I'll post it.

post the original bios..

Mine's presenting the same symptoms as @rgorbie. However, I did not flash the backup back onto it. I don't see any other chip on the board.

I couldn't specify the chip as per the label on it:

Reading flash...done

The md5sum of the 2 separate backups matched. So did the md5sum of the bios read after flashing the bios in the second post of this thread i.e. it's successfully flashing. Just not working/booting. Any ideas?

Re: Please my bios clean me

try..

Thank you for this. I have an m710q 10yc s00p00 motherboard v1.1 and read my bios chip(locked to Amzn)with a raspberry pi and a chip clip(generic pamona clip)@ 16,777,216 bytes. I tried to flash the bin from the Lenovo firmware package on their site and only got an error with flashrom.
Error: Image size (8388608 B) doesn't match the expected size (16777216 B)!

So I used the one in post #2, it kept failing to verify the image to the W25Q128.V chip but it did allow me to boot from a USB memory stick that I had set up to install Tiny10, used Tiny10 to run the Win10 firmware flashing utility from Lenovo site to make sure that the firmware was correctly and completely installed then reset to factory defaults. Now the system is working properly with Ubuntu 23.04 installed. Once 23.10 ISO is finished I will actually install that.

Thank you so much for posting!

For those that also get a failure, make sure that you have your USB installation media set up properly and ready to go, I was surprised that it worked even though verification didn't work and the sha1sum of the dump afterwards was different than what was written it still got the job done, so don't give up.

On mine pressing F12 while booting was used to select the boot media.

Not sure if posting my original firmware file would do any good but if needed let me know.

Try using the latest version of flashrom, earlier versions didn't detect my chip properly.

That wasn't so successful:

Please run "flashrom --help" for usage info.

Broke my clamp in the process. FML. Now I wait for a replacement.

Re: M710q Please my bios clean me

It seems that all the knock-off clips/clamps are generally junk, if I were doing this more than once I would get a Pomona clip. I got lucky with my el cheapo version, I actually bought a ch341a_spi kit that I ended up only using the clip from.
After reading this I had decided not to use it: https://libreboot.org/docs/install/s...not-use-ch341a
So many have had success with it though, so who knows, but I didn't want to risk it.

I ended up using a Raspberry Pi 3B to do the programming with the latest version of RaspiOS (bookworm) and used the flashrom that was in the repo.

While we have the same machine 10YC and version 1.1motherboard, I also have a different model number on my label.

I attached a picture of the motherboard with the chip I flashed circled in green.

Hi , technically my first post here, I am trying to bypass the Amazon Chromium firmware for multiple M170q's
I Used the bios file in this thread ( by peste) and 6 of the 7 PCs worked fine , they are all identical with minor differences in bios chips, the 7th PC won't post , it powers on as soon as I plug in the DC jack , I tried to flash the bios many times with the exact same file I used for the rest 6 PCs but no luck , any ideas?
I Used the CH341A programmer

Update : turns out its a dead bios chip , replaced with other 128Mbit / 16 MB and worked just fine
