[REQUEST] Lenovo Y40-70 (99CNxxWW) BIOS Unlock

[BDMaster]

I have a Lenovo Y40-70 that I am also looking to unlock the bios for. I found this thread, and from OP description, I have the exact same laptop that he does. From reading the thread, it looks like the BIOS has to be downgraded from 99CN28WW to 99CN24WW, then reflashed with the modified BIOS. Unfortunately, I cant find the old BIOS rom anywhere.

Because I know they will be needed...

Heres my current 99CN28WW BIOS rom:  www.sendspace.com/file/u9q9m0

Heres my AIDA64 Report:  www.sendspace.com/file/s5j30n

Heres the other BIOS Report: www.sendspace.com/file/8xzex2


Thanks for the help!!

Need help flashing BIOS or recovering it without a screen. Disabled intel gpu and npow nothing shows. I  removed the cmos battery for a while and still no luck. Help please.

Boot blindly into BIOS then press F9 enter F10 enter.
F9 will reset default settings, F10 will save and exit

Hey! I have the exact same laptop you have. 

Have you tried these steps? https://www.bios-mods.com/bios-recovery/...-recovery/

In the thread I started, you should be able to find the 99CN28WW bios.

As a side note, can you upload the 99CN24WW bios? I want to flash my bios with the unlocked one the other guy made for you, but I have to downgrade the bios first.

Anyone still out there? The thread has a ton of views, so it seems quite a few people are interested...
