There is no software utility that will backup the bios,the only option is to use an SPI bios programmer

Read the rules in the sticky thread and post the service tags ! https://www.badcaps.net/forum/troubl...before-posting. Clearing the 45000 region does not always work.Compare a locked/unlocked bios with a hex editor and you might be able to work it out

Thanks for your help. Anyway somehow clearing 4000 bytes starting from 45000 address worked. I was doing it a bit wrong. youtube video if someone needs. https://www.youtube.com/watch?v=UAxdl59j7u0

I followed the instructions in a youtube video to edit the hex code and it worked!
Here is the youtube video:
