Hello, So I followed every step in this tuto in order to flash my y510p's BIOS. https://forum.techinferno.com/lenovo-ibm/4668-lenovo-y410p-y510p-unlocked-bios-wlan-whitelist-mod-vbios-mod.html . Operation successful. However I modified something related to video card (GT Voltage offset). Now laptop only shows a black screen, no windows, no bios, not even the lenovo logo. I tried putting the yx01.bin file in a flash drive, hold Fn+R and power on; the flash's led starts to blink for about 5 seconds and the laptops suddenly shuts down. Is my laptop dead ? is there a way to fix this please ? Thank you
