ThinkPad T420 1.48 modded BIOS WANTED

[HEYZOOS]

As we all know its quite hard to downgrade from 1.48 to 1.46, so can anyone have the ability to do a white-list bios mod OR an easy downgrade option.
Thanks in advance.

Hey, thanks for the reply!
Yeah still having issues, Am I being dumb, I have the original and modded 1.46 BIOS for downgrading from 1.48 and i'm struggling to make this solution work even though i'm told on here it's the solution?! Any help would be much appreciated. Thank you all once again

I tried to flash from msdos creating a bootable USB as shown in this tutorial,https://www.bios-mods.com/forum/Thread-HOW-TO-FLASH-MODIFIED-OR-ORIGINAL-BIOS

but it only works if you have the BIOS.WHP file,I can not continue, I have not found that file ( bios.whp ) in any modified bios I downloaded ( I've tried 3)
