I had v2.07 BIOS on my Y580 and tried to make a DOS bootable USB to install Modded v8 BIOS. Installation completed successfully and then I used the same method to install original BIOS. That also succeed but when I reboot I have black screen and no boot. Fn+B method with v2 BIOS not working (I have done it successfully in the past). In need some help, Thanks in advance.

Hello, I own a Lenovo Y580 (Windows 7 and i7-3630QM Processor). Today I tried to upgrade BIOS with Lenovo utility but after a while screen went black and fan was working at 100%. Laptop remained in this condition for over an hour and I had to shut it down. After that laptop is not booting anymore. When I try to boot I can hear it working, power light is on, keyboard light is also on but nothing happens. Please help.
