https://www.bios-mods.com/forum/Thread-R...5#pid80695

AutoMod (thanks to all modders and to CodeRush an extra)

Using CodeRush Tool UEFIPatch + Patches.txt, We can do the Mod by ourself, in any time and wherever We are !!!

Just use the right Patches.txt for the own Bios Version, so for your Bios use this one !!!

How to use ?
It's easy, just do a biosbackup.bin file and drag&drop on UEFIPatch.exe (the Patches.txt file has to be togheter at tool)
It will reply with a file patched, then rename that file as bios.bin, put It into modified folder where are all rest tools
to re-flash the Bios Mod and copy all files from modified folder to an USB Dos Formatted Bootable Stick and Boot from USB !
Then, reboot the laptop and at CLI Prompt Comand run flash.bat That's It all !

CodeRush Tool (above)

Modified folder with all tools to re-flash Bios Mod from USB, follow instructions (above)

Update from pure DOS with USB-bootable stick (You can use Rufus also)
See how to make one here:

http://www.howtogeek.com/136987/how-to-c...usb-drive/

https://rufus.ie/

Copy the "Modified" folder contents into the stick and boot in DOS mode and
Run Flash.bat to update.

Don't touch Video Settings or Disable Video Card It will Brick laptop !!!

Please post results.
This mod for your PC only!!!

I hope It will become the New Mod Way !!!

Here Patches from 31 to 52 (above)

BDMaster studied, searched, used and explained to friends, how to generalize a bios , so it's possible to flash using Intel FPT Tool , without any backup Wink
Also used the CodeRush Tool to fiind a way to get free all users to self-make a Bios Mod , using the Patches files Wink
I have a lot of guides and notes which I wrote about the Bios Mod where all is explained and sooner or later, I will publish them here Wink
Sovem (GREAT bios modder ) applied all in this one

Generalized version for all Wink

WL removed
Menu unlocked

Hi, I tried to flash your moded BIOS. But getting this error during the process:

Error 28: Protected Range Registers are currently set by BIOS, preventing flash access.
Please contact the target system BIOS vendor for an option to disable Protected Range Registers.

I have exactly same issue as you with overheating problem, is there actually any option for controlling the fan speed in BIOS after flash?

If anyone needs to control the laptop fan speed, just use this app:

Hi, I just replaced the screen on my Lenovo Z500 Ideapad and I'm having trouble with the brightness control. It would be great if I can remove the whitelist. Here's my result.rar:
