[REQUEST] Lenovo Y50-70 (9ECNxxWW) BIOS Unlock

[Da Vinci Code]

I think win 10 is reason of all fails. So in future i never do mods before downgrading win 10 to 8 or 7...
Did you unplugged wifi adapter, mini-pcie slot must be empty?

i didnt unplug wifi adapter since i dont know which one is wifi adapter ! all stuff in lenovo y50-70 are so soldered which make unplugging really tricky for me.

i just removed the battery and the CMOS battery connector, then pushed the power button for like 30 sec (as it was explained in another thread) and then power it on, and even checked the bios setting afterward and "date" was reset to 2013 which is a sign of successful CMOS reset procedure.

if it's really necessary to unplug the wifi adapter, would u kindly walk me through which unit is wifi adapter

ok i should take the whole wifi adapter out ? or just take the antennas out ?

and when i did that, i should make CMOS reset again ?

dettach antennas, unplug adapter. Clearing CMOS not needed
NOTE!!There is big mistake at video!!
You must dettach battery and AC Adapter first before disassembling laptop!!

thx for the note
so after complete detachment of wifi adapter, then i should plug the ac adapter in and turn the laptop on while still the wifi adapter is detached ????

(i'm gonna try this in the morning since it's really late now and i'm gonna let u know of the result)

Try to disable UEFI mode and enable Legacy, disable Secure boot and boot from usb stick with mod and flash it!

i just tried that man, didn't work !! system seems have a problem to boot in general, nothing boots

even i made my usb windows 10-bootable to see if it can boot from windows installer, didn't work either !
