Razer Blade Stealth 13" RZ09-023393 Bios downgrade request to 2.0.1

Is there any way to obtain Bios 2.0.1 for my Blade Stealth 8550U RZ09-023393? I am having some issues with latest firmware and would like to revert to stock. Also, is there anybody willing to help me by dumping their Bios? Should be a fairly simple and safe task: By extracting the latest Razer Update Utility with 7Zip or WinRar you should find a file AFUWINx64. http://drivers.razersupport.com//index.php?_m=downloads&_a=downloadfile&downloaditemid=2859 That's AMI Firmware Update Utility v5.09.04.1503 on Windows saving the code below as a .bat where the AFUWINx64.exe file is located and running it from and elevated CMD window: @echo off echo========================================= echo Backing up Bios... echo========================================= AFUWINx64 bk.rom /o if errorlevel =1 goto error echo= echo==========Bios dump success ~!=========== echo= echo= goto end This should create a .rom file with the backup, it's a read only operation so it's safe, I have tested this myself on my blade. Would really appreciate the help or any suggestions from support regarding this.

Seems that downgrading is possible but still facing issues, as if not all parts got downgraded.

Edit: My bad I forgot to write the boot block! All is good now, successfully downgraded Bios, will link details for anyone looking to do this (at your own risk!).

@danausx Thanks for sharing this. That said, the method shared above is rather risky, which is why we strongly dissuade people from doing so. There are way too many things that could go wrong. *Thread locked.
