I followed your guide and everything went smooth. I also installed a dual band WLAN card which works just fine

Thanks, I really need this Bios

For those who don't like the restrictions Lenovo put on their system, here's a BIOS mod that will get you back at least some of the freedom you should have over your own hardware.

Features:

• WLAN card whitelist removed, any (hardware-wise compatible) card should now work
  
• hidden BIOS menus unlocked
  
• VBIOS tweaked for more performance and better tuning possibilities
  

Keep in mind that not necessarily all of the BIOS options available with this mod will be fully functional, so use the new available settings with care.

If you're unsure about something don't change it and ask here, someone might be able to help.

Available for v1.07 / v1.09 / v1.10 and v3.05.

v2.04 and v2.07 added (only whitelist removal as for now)

If you have a different BIOS (or more specific, a BIOS newer than 3.05) I will need a copy of it in order to make it work for your system.

Instructions for flashing the modified BIOS v3.05:

You need a USB stick prepared to run DOS, here is a guide you can follow in case you don't know how to do this:

Guide by @StamatisX - thanks!

>>> Before continuing make sure the AC adapter is connected to your laptop and your battery has at least 20% charge remaining. <<<

• (0) - NOTE: This step is Only necessary if your system isn't already using BIOS v3.05
  Update to the official v3.05 BIOS provided by Lenovo
  .
  
• (1) - Create a backup of your own BIOS (now v3.05) by using this tool.
  Extract the files and run the included .bat file from an admin command prompt.
  .
  
• (2) - Download the files for the v3.05 mod, put the files of folder [1] to the root of your prepared USB DOS stick.
  Let the BiosFixer prepare your BIOS for flashing by drag and dropping your backup file on it. Put the created "v305mod.bin" file to the root of your USB DOS drive as well.
  .
  
• (3) - Now you need to downgrade the firmware back to v2.07 in order to flash the mod.
  .
  
• (4) - Boot from your USB DOS drive, when you see the command prompt type BIOS and hit enter. Wait until the BIOS is flashed (you can safely ignore warnings about non-existing regions).
  .
  
• (5) - Once the BIOS flash completed with no errors, type EC and hit enter. Wait until the EC is flashed. Then reboot.
  .
  
• (6) - Go to the BIOS setup menu, load the default settings, apply and reboot.
  Done. In case you're using an ultra bay GPU follow the instructions in post #2 and flash the vbios..
  

NOTE: It's crucial that you flash both, BIOS and EC. Having different EC and BIOS versions can in certain situations lead to issues.

IMPORTANT: If you want to go back to stock v3.05 you can do that easily by simply using the official update from Lenovo. That's it, nothing additional required in this case.

Old instructions for users with v1.07 / v1.09 / v1.10 or v2.04 / v2.07 who for some reasons don't want to update to v3.05:

• Create a backup of your own BIOS by using this tool.
  The archive contains the files of the program and a .bat file that will create a backup of your BIOS. You need to call the .bat file from an admin command prompt.
  Don't delete your backup file, you will need it in case you want to go back to the stock BIOS some times. Also don't share it since it contains your personal Windows key including activation.
  .
  
• Download the attached BiosFixer, simply drag and drop your BIOS backup on it and it will create your personal mod for you.
  .
  
• Flash the modified file with the tool from the first step, use the command below:
  

  fptw64 -f v1xxMod.bin -bios

  
  .
  

• Wait for the flash process to finish, if you don't get an error reboot. (You can safely ignore warnings about non-existing regions).
