I can confirm that fptw64 successfully flashed my bios in windows 8.1 environment. However, error 28 still appeared. Only by using the sleep mode method that I got my bios flashed. (dos without the sleep mode method worked neither)

But wait, does this mean that i can now flash my bios from windows because i get protected range register error in dos mode on my toshiba sateliite c55-a5285. How did you flash it, I ran fpt/fptw64 with the command "fpt.exe -i" and got fpt passed "in dos btw", but the bios didnt get modified ?

I can confirm that Vodek has found the right NVRAM variable to unlock Error 28
and to show the Advanced - Power Tabs !
We have to check on all Acer VN7 series Laptop !

Why are You doing from Dos using FlashIt ?
What is the problem ?
Upload the Setuputility _670.ROM Module file !
Explain better what are You doing as It seems You haven't Windows . . .
Let me know

I made a pure DOS with USB-bootable stick and copy the "Modified" folder contents into the stick and boot in DOS mode and
run Flash.bat to update. But I also GOT THE ERROE 28 and then I attempted to use flashit ,but failed.
