How to Downgrade the BIOS on your Lenovo ThinkPad T430/X230

Hello So say you want to do some Mods or remove the whitelists for WI-FI or something on your T430/X230, BUT you are on say a too new version of the BIOS, well you¬ out of luck! Now the installer that Lenovo provides you with will refuse to downgrade as you already have a newer version. With my tutorial you can get round this by Flashing the BIOS directly via command prompt getting round any checks to see if you are on a newer BIOS. In this case, i wanted to remove the WIFI Whitelist but i was on Version 2.82 and for the WI-FI Whitelist removal i would need to be on 2.64. This may work on say the, T420 and X220 but do this at your own risk. Confirmed this does also indeed work on the X230. I downloaded my BIOS from here: T430 BIOS Downloads from Lenovo UK T430 BIOS Downloads from Lenovo US: X230 BIOS Downloads from Lenovo UK X230 BIOS Downloads from Lenovo US: If you found this helpful, please subscribe and let me know your thoughts.
