yeah, i know donovan´s site... i think i had removed the whitelist by replacing the jnz (in assembler: jump if not zero) to a jz call (jump if zero) referenced where the text is loaded and a new subroutine were called... which locks the bootprocess...
but for now insydeflash is giving me with that mod a secure flash warning with invalid image description.. i´m not sure if i can bypass this to try this mod... if that´s it i will post the modded bios image to give you a try with that. Still working on this but have only this day for that...

So i have unlocked bios now on my Yoga 2 13 some pic´s:
Moderator Note; link to picture showing system s/n removed to prevent possible abuse
Gonna call BS on this. The problem is not unlocking or removing the whitelist (@the other dude, whitelist removal is simple).
In fact, for the Y2P, here you go folks:
0x918A4 Boot (0x54 from string package 0x0)
0x92624 Security (0x32 from string package 0x0)
0x92C84 Main (0x3 from string package 0x0)
0x93284 Power (0x396 from string package 0x0)
0x96A54 Advanced (0x144 from string package 0x0)
0xA5DB4 Exit (0x88 from string package 0x0)
0xA5FD4 Information (0xA9 from string package 0x0)
0xA6214 Configuration (0xBB from string package 0x0)
0920 : 74 5F to 74 00 jz short loc_180000981 to jz $+2
092A : 74 55 to 74 00 jz short loc_180000981 to jz $+2
0930 : 74 4F to 74 00 jz short loc_180000981 to jz $+2
0302 : 75 17 to EB 17 jnz short loc_18000031B to jmp short loc_18000031B
034A : 75 18 To EB 18 jnz short loc_180000364 to jmp short loc_180000364
I bet the pics quoted were emulated. They are not real. If they are, how did you flash a locked BIOS? please share.

Hi, thank´s for removing...
The pic´s are real, i had flashed it loaded the bios as OEM from there are the pic´s, i was playing around with the intel 7260 ac card with booting with the original card and plugged off the Intel card while booting windows... on next connected the battery off while boot and plugged in the battery and powered it up while holding Fn+F2 to enter bios setup "as OEM" you can see it on the "Debug" Tab in BIOS, same way while started the H2OFFT-W.exe in Windows before it rebooted plugged off the battery and hold down Fn+F2 key while powered it up again so flash has completed normallay without this secure flash warning, but for now this way don´t took me anymore for a succesfully flash procedure... with the new modded bios without the whitelist... so for now i´m looking to bypass the secure flash warning...

Again, please provide some videos.
Else, I will file this as BS. Trust me, I have tried and failed in this dept. Not to say you are not better but, I have some knowledge that most don't.

Please try to boot with enabled wifi in bios but without any card in the m.2 slot, while booting OS insert a non whitelisted card in the slot and put the batterycable out while loading, then put in ac adapter and power up the Computer while holding Fn+F2 keys.... For now you should be in an unlocked bios in OEM-Mode... same step to flash without signature check (without the secure flash warning...) i flashed it sucessfully... please give it a try...
So noone here can confirm that this is OEM Mode of the new bios V. 1.11 from Yoga 2 13??? Or can confirm that the Sata Adapter is pluggable to a standard Sata (S)HDD???
