IdeaPad 3 14ADA05/15ADA05/17ADA05 Lenovo V14-ADA/V15-ADA Bios

[peste]

Hi everyone,
In my case the notebook (15ADA05) failed to start after BIOS update E8CN41WW
I got the motherboard model and release, but as the system doesn't start anymore how can i find the S/N ?
I still have a backup of the former BIOS. Can i write it using the USB key and Fn+R procedure ?

Regards

Chris

post S/N, full name and model, motherboard model, TYPE,etc.
You can find the s/n on the label on the case.
post the contents of the bios chip even if it is corrupted..
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..

you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

A picture is better then one thousand words.

The rules override what you think is right. We can copy text easily, why should we who are giving help have to look at a picture and type it ourselves. Very often the pictures that are posted are too small, rotated 90 degress left or righ, upside down or blurry. In such cases rather than being worth a thousand words it doesn`t mean anything and wastes our time.

There`s a number of reasons why we ask for the serial number -

We can find the bios/update at the manufacturers support site.
We can check the laptop model type (lenovo) or configuration (Dell)
We can check if the posted serial number which is usually on the sticker matches with the serial number in the bios, or EC.
Asking for the serial number might put off some from posting at all if the machine is stolen.
We can check if the bios has already been posted by someone else, or by the same member using a different account asking for the same bios to try and get help quicker.

I pulled the bin file off the bios chip but I can't seem to find where the password is located to translate it from a hex editor.

I have found Password string in binary file (offset 0x00310529) and set to 0x00 somme bytes inspired by another patch I found on the site but it didn't change anything. In the example I found there were two Passwords to patch, for me only once.
