BIOS for Lenovo G50-80 i5 AMD Radeon

[Online_internet]

Hi,
A BIOS flash will be necessary on my Lenovo, where can I download the correct version of the file? I have only seen the .exe version on the Lenovo website.

Model: Lenovo G50-80
Processor i5
AMD RADEON graphics card

Motherboard model: ACLU3/ACLU4 NM-361 Rev: 1.0
5B20H14432
MBLG50-80W8SI5-5200UM330 2G1000

BIOS: 25B64BSIG

Programmer is CH341A

Hi,
Thanks for your support and guidance in the right direction. This is my first time with BIOS flash.

I didn't enter the serial number because my sticker on the case has long since fallen off. I picked up some knowledge from the internet and learned about the UEFItool program. I managed to rip the (probably corrupted) BIOS, checked it and saved it. I then pasted it into UFEItool in order to find the serial number, unfortunately, as I found out later, in the case of lenovo it is encrypted.

I also learned how to extract the BIOS batch exe. to .bin. The attempt was successful. Unfortunately, I am not sure which parts from my BIOS I should replace to the new one. I'm also not sure if I downloaded the correct bios from the lenovo website because, as I mentioned earlier, I don't have an SN.

Will you please direct me to the solution I need to properly flash my bios? Other than the fact that I need a good bios to flash, I would like to understand so that next time I can do it myself without troubling others to do it.

I add my BIOS as an attachment.

I checked the serial number of the laptop you provided a link to and it has different parameters:
Intel Core i3-5005U Processor(i3-5005U)
Intel HD 5500

Will everything be exactly the same in the case of my laptop?
