[REQUEST] Lenovo Yoga 500 (BDCNxxWW) BIOS Unlock

[PIRATA!]

Does the tool comprehend FPT?

yes, FPT 11.x.x.xxxx

I run cmd as admin but I don't get any biosdump.bin created and I find this error in the fptinfo.txt :

Code:

Intel (R) Flash Programming Tool. Version:  11.0.0.1160

Error 366: Fail to load driver (PCI access for Windows).
Tool needs to run with an administrator priviledge account.
PMxdll.dll DebugMsg: Call to PMXDestroy()

Update!!!
From DOS:

Hello, I'd also like to request unlock for the latest bios version for yoga 500: https://pcsupport.lenovo.com/vn/en/produ...s/DS102775

If I understand correctly, you also need a dump of bios that's already present on the machine. Dumb question but I wasn't able to figure that out from this thread since most of the links are dead -- do I need an eeprom programmer to get the dump or can I get it through some software utility, possibly one from the Modding tools section? Thanks in advance

I have exactly the same BIOS. I will try to read it later today and upload here.
My issue is I have replaced the wireless card for an AX200. Wifi works great but bluetooth does not get detected by device manager. Not sure if its a UEFI whitelist issue or a hardware issue with the card.
What are your thoughts?
