I must confess I am still on v26. I'll have a look at v91 as so soon as I can (not so soon).
Btw some newer versions than v26 had the very same offsets.

Edit: I just had a look at lenovo site and wasn't able to find v91, the last version they provide is v32 (9ACNxxWW), are you referring to 91CNxxWW bios? If yes please provide me a dump.
Here is the v91 BIOS I'm using on my Z50-70:

I am sorry but I can't provide a BIOS dump now, I will post it here as soon as I can.

Hi
I stuck in the first step with Universal Bios BackUp ToolKit 2.0 -
I run the recommended BIOS 9bcn26ww and changed bios to optimal defaults. I disabled WIFI in Bios because I already plugged in my new WIFI card.
In Windows 8 I am logged in as Administrator. The first strange thing is, that Win8 64Bit doesn't show the .exe in my BiosBackUp ToolKit 2.0 Folder. Win8 says the folder is empty while its not. In short - the only way to see the .exe is to navigate via network to the .exe file stored on my Mac. Then I can right click it, select "Run as Administrator" - The Applikation opens with an error, that I need to run it as Administrator. How wired is that!!! I have the Windows open then, but can´t do a backup ... I tried also to open it via USB Stick. But the same. The file is hidden.
An idea?

Can this same guide be used to remove the BIOS Whitelist on a Lenovo Y50? If not, can someone please explain how to.
Thanks in advance.

No need to remove the whitelist. You can use a Lenovo branded WiFi card. Read post #1 of the Y50 guide.

Could anyone reupload ftpw64.exe? As the dropbox link seems to be broken.

Can you please check the offsets that need to be replaced in the v91 BIOS?
I am using v91 BIOS and a BCM943602BAED (DW1830) wi-fi card now and I used the same instructions of this thread to make it woking.
What I needed to do was dumping BIOS on V91, patching it, downgranding to V26 (just to use the sleep bug) and flashed V.91 BIOS.
I could not flash the BIOS using ftpw.exe on V.91 - LENOVO fixed the sleep bug on this new version).

Patched v91 should be flashed on v26.

You must run command.exe with administrator privilegies.
