what didn't you understand??write the bios on the chip from post #56..you also wrote the DMI interval there...what's the problem?...the bios is ok...

Ok thanks ♥️, I'm gonna write the bios I have just made.
Anyway don't want to be rude but the post #56.. doesn't contain any bios file put as attachment.
As you can see from my screenshot

Thank you for the file. Do I have to inject DMI into file ? Because i only got black screen. No post. Power light is on (no blinking) And the fan spins for a 5 seconds.

DMI has been fully added to the new file. Find hardware problems.

Hi,

As the rest of you here, I'm getting no screen output, caps and Fn-lock led's working and power button led flickering. Holding bios recovery button or novo button (small hole next to power led) results in two short beeps and nothing else.

Don't have access to old bios, and I don't know my way around hex editors so I would be grateful if someone could copy my DMI info onto a virgin bios. Thanks in advance!

P.S. I don't have a programmer at all. Is this possible to do with only a USB stick by forcing bios recovery mode somehow, or am I going to have to get a programmer and dump my bios old somehow that way then flash new using that DMI? (I was unable to access bios through every option like novo button, Fn+R etc., I corrupted my bios somehow after deleting windows EFI partition, which is odd as deleting SSD partitions shouldn't affect bios but whatever, all symptoms seem to be pointing to bios corruption)

As the recovery method hasn`t worked you will have to make a backup using an SPI programmer. The DMI can be transfered from your backup to a virgin bios.

Hello, since my last post I bought a CH341a Mini-Programmer from Ali-Express and I just now tried to read the old bios from it, however whenever I try to read, it gives back FFFF values, or ID Unknown Error (see screenshot). I read up a bit on this and after making sure that the clamp pins are correctly contacting the bios chip and after trying with every driver I found, I stumbled upon a video where the guy says that these values mean the bios chip is completely empty and there is no old bios on it. Any tips on how I should proceed?

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..
here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

The bios chip is 1.8V ,did you get a 1.8V adapter with the programmer. The ID Unknown Error is because the 74M12JW is not supported by the programmer software. Use NeoProgrammer or ASProgrammer software and choose W25Q128FW manually, don`t use the Auto-detect. Also read what peste said, if you have the tools to desolder the chip or solder wires instead you will have a better chance of making a good backup.

Thank you! I desoldered it however the video was a little outdated in my opinion so I found this one which helped me more, and might help someone else as well in the future: https://www.youtube.com/watch?v=z9uLPo9QAY8
I was able to read the chip (it ID'd it automatically without me finding it manually) and have attached the old bios in this reply. As a last request, I would be grateful if someone could transfer my DMI info, thank you again!

you have everything you need at post 56

the bios from post # 56 is virgin, use the HxD program (it's free on the internet), enter both bios into the program (your laptop and the virgin one),
select that interval mentioned in both bios, copy the interval in your bios and pass it to the virgin bios (copy - paste)....and that's it...

Hello, guys. I'm sorry, but I'm a complete idiot about it. I absolutely don't know how to modify bios.cap. I can handle how I get it on the chip. But I don't have a bios backup, as it turned off the laptop during the update.

IdealPad 3-14ALC6 (82KT)

I try one in this thread, but still dont work

Thank you very much

post the contents of the bios chip even if it is corrupted..

I believe, that you mean this

you have everything you need at post #52..

[Hugh Mungus]

Thank you. It works. But please how I can have my original serial number?
Plus now I can´t use more than 512mb for graphic (bios setup-I have 20 GB RAM). Before I could do it to 2 GB for graphic.
Thank you one more time and I will donate for 100%.

Copy your DMI to the new bios using the attached script, read the README.txt file for instructions.
