Hello!
Your mod cannot be flashed
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.
Let's try to bypass it. Set your laptop to suspended mode and wake up it after few seconds, then run tool again.Check results81.png for red text.

Hi Da Vinci

I try manipulating a few times but I still get the error 28 , in my opinion the bios 1.48 is very locked.

thanks a lot

I'm trying to figure out how to flash 1.46 BIOS with all the sweet upgrades and I just can't figure it out and my Google-fu has failed me. When I run the .bat file (from command prompt on Windows 10) it runs WINUPTP.EXE -s then does nothing. If I'm missing something obvious then let me know. Maybe that's all its supposed to do?
Edit: got it to work. Do the BIOS posted here by BDMaster also included the egpu fix?

Can i downgrade my bios from 1.48 to 1.46 by using winflash or using another method? Thank you for your help.
