[REQUEST] acer bios file Aspire 5 A515-51G-C97B

I'm trying to make a bios mod for my acer, I'm trying to get the bios file. I got an isflash.bin file, but when I'm going to make some changes in it from the error and some applications to make modifications says it's not compatible.

I got the file running the application C5V01121.exe made available by the own acer on her site and going in the folder:

 C:\Users\flavio\AppData\Local\Temp\7zS3007.tmp/isflash.bin


I believe this is not the actual bios file because it has 9.2mb

I would also like to know if anyone can unlock it there for me. I've got some hidden options on the bios, but I do not know how I did it.
