Help with Ideapad 310-15isk BIOS reprogramming

[movilico]

Hello.
I have a Lenovo Ideapad 310-15isk, with corrupted BIOS.
I have used CH341a programmer to make a backup.
I have installed from this forum a BIOS dump, but now I don't have the product, s/n...
I am not able to extract that data from my backup with the HxD program nor with UEFITOOLS.

How can I recover it?, I need help

I send my backup

Using HxD search for the text: LENV .The DMI is crypted,there`s 2 LENV areas to copy,use the offsets in the picture, copy from your backup and paste-insert into the same offsets in the new bios.

It took me several attempts, but in the end by copying offset 234000 to 235FFF, I did it!

Thanks a lot SMDFlea

Hi everyone,

I have a lenovo ideapad 310-15isk after a restart before or on the lenovo logo I held the power button to power it off. After I tried to power it on I had black screen, cpu fan working the laptops works for about w0 secs and then restarts automatically and the whole process repeats. I tested many ways and at last I found that the problem is the bios. I want to flash the bios using a USB flash drive.I have three problems and I really apreciate your help.
1. which file to use for ideapad 310-15isk A751 Rev 1.
2. what should be the exact name of the .bin file so that the computer can read the flash and the bin file when I connect the USB flash drive?
3. what keys should I hold before powering the laptop? (I hear fn+R, but I am not sure whther it works for this model of laptop).
If there is any other procedure I should follow,please tell me.


thank you so much for your time.
Hamid
