Hi!

In your laptop model, any modified bios can be flash using hardware SPI programmer only, exactly the same as described in the first post of this thread:  

 

So, for creating backup (dump) of bios you need to use hardware SPI programmer only.

 

 

Hello Klem,

Thank you for the instructions. But with CH341A I will get the same bin file which I flashed in my laptop. I flashed the BIOS using the file I share with this method only. So the dump will be the same file I shared with you. Do I still need to make another dump file??

Hello

I have a Lenovo G580 20157. My BIOS was locked and I tried to make bios dump using ftp, but it didn't allow me. Then I tried using CH341A and Pomona Clip. In the process I bricked my BIOS and My laptop was dead for 2 days. Fortunately I was able to reflash my BIOS using a bin file I found on internet and now my laptop is working fine. My BIOS is also unlocked.

I need help in whitelist removal, and unlocking advanced menu, if you can help me. I am attaching the bin file I flashed to my BIOS.

Hi, Thank you for your reply.

What if I downgrade or upgrade my bios to 62CN44WW or 5ECN96WW?

Will that be flashable without use of hardware?

I have made BIOS dump. Please help in whitelist removal. Lenovo G580 (20157). 62CN97WW
