Hey guys I have a big problem ; I changed my primary video settings from bios after black screen of course. I downloaded y580 bios mod from here for use restore bios. I changed rom name and fn+r and flashed bip sound finished but didn't restart still I waited some after I shut it off. I wanted try again but laptop bricked I press to power button but no reaction. I think bios rom has a problem.. So what can I do?

I don't know if this works efi systems but on AWARD bios  you basically find the stock vbios or module part on the bios then replace it with your desired file and some trimming here and there so that the modules are where they are supposed to. Be prepared with at least a replacement bios chip and a soldering iron as it is highly probable that the product will be unbootable.are you overclocking the 660m ? slv7 has already made an unlocked bios with an overclocked vbios included as well :

 

Yeah I know but I wanted try best overclock for my gpu because you know chips are can be different

likely you have to use bios modding tools to insert the vbios failing that probably with hex editing software best left to seasoned bios modders instead as differing sizes and possibly starting addresses of the vbios and other modules even a different order of the modules is enough to cause the bios to be unbootable.   

How can I do it with hex editor ?

Idk, but you can flash the unlocked BIOS and overclock and undervolt using Inspector. No point in wasting your time with those settings anyway since they won't be stable.

I have unlocked bios already but I cant change voltage from inspector

Before flash, you need insert your mod vbios into system bios, and then flash whole bios. Unfortunately I am not a teacher, and I can't give training to you. I am sorry.

How can I insert ? Which program ? just tell the name of program please

Hey guys, take it easy!

 (10DE,0FD4,17AA,3977) - it is Lenovo G580, therefore vbios is a part of system bios. In this case he have flash whole system bios of laptop. A great way for him, in his case just read carefully this link:   https://www.techinferno.com/index.php?/forums/topic/1769-lenovo-y580-y480-unlocked-bios-versions/

Thanks but it is for Flash bios not vbios  I mean I cant put vbios into to bios flash file. I prepared just nvidia bios file not all bios file. So I dont know how to put inside bios file. When I tried ' Warning: The file does not contain enough data to completely fill
         the target write area! Continuing will truncate the Write
         Length to the File Length!
            File: "bios660m.rom"
            File Length: 89600
            Write Length: 4718592  İt says size is so less because just vbios not all. Can you help me ?
