It's always best that the device has the correct info, so I just moved your DMI from your dump file to the working BIOS from post #14.

Now you shouldn't face any problem.

This one is corrupted, I believe my dump corrupted this part but the other one (for V15 G2) worked perfectly! thanks!

flash bios on lenovo ideapad 3 15ACL6

Hello,

i'm new here, so i hope im correct here.

My lenovo ideapad 3 (Mainboard HS461&HS561&HS761 NM-521 REV2.0) is broken and i will try to flash the bios chip new. But my problem is, that i found only one chip called "winbond 74M12JWSIQ" is this the correct chip? Because normally all bios chips should be started with 25*** or i'm wrong?

Yes, it's the correct chip, (16MB-1.8V).

Re: lenovo ideapad 3 15ACL6 bios request

Read post #20

.

I read literally every post, on every thread, that was even remotely relevant, which unfortunately, was hundreds. It got all jumbled up in my head.

Post 20 says to read post 4, the copyDMI guide. It also says to remove the header but it's unclear if I remove the header from the "oldbios" AND the "newbios."

The "newbios" is the bin file made after unpacking the Phoenix TDK file, mentioned in a different thread on this site? Does it matter that my original bios ("oldbios") is 16,384 kb and the "newbios" is 8,192 Kb? attached both.

Sorry if these sound like stupid questions. Thanks for your help!

Reading all related posts is not enough, you must try to understand all the information in that posts otherwise you just read some text which obviously is not very fruitful as you (and I) can see.

Slow down - first of all old bios is needed for copying the DMI information in it - nothing more, nothing less, so all the modifying we must do is related to the new file i.e. new bios. Secondly if you try to read the guide more carefully you will see that you must remove the header from the bios.cap file extracted from the bios update executable downloaded from the manufacturer support page.

The "newbios" is the bin file made after unpacking the Phoenix TDK file, mentioned in a different thread on this site?

That's right - after extracting the bios.cap file from the update executable we must cut it to have the new (virgin) bios dump, and after moving the DMI information from our old dump to it we have the finished file ready to be programmed to the bios chip.

Does it matter that my original bios ("oldbios") is

16,384

kb and the "newbios" is 8,192 Kb? attached both.

Don't want to be rude but that's B.S. Both old and new file must be 16,384 KB each.

Post #4 is about 41 version (GLCN41WW) of the bios, so first things first, the link for you to download this update executable is:
https://download.lenovo.com/consumer...s/glcn41ww.exe
Download the file, extract the bios.cap file from it, attach the file in your next post when ready, and we will continue to talk after that.

I didn't use GLCN41ww because that's a very old version. I used GLCN52WW.

I figured it out. I was following the post about extracting TDK files and it says to select/copy 0-800000 but my chip is 16 not 8. So, I made the adjustment and got the DMI info in. So, I am ready to hook up my programmer. I was making it much more complicated than it needed to be.

Thanks!

Re: Hs461 hs561 hs761 nm-d521 rev 2.0 bios plz

The flash worked fine but my issue still exists. I have a motherboard virus that apparently can"t be removed. Flashing the spi was the last resort. I guess I will be throwing away a laptop I bought less than 3 years ago.
