Yes it shows Error 28 Error 28: Protected Range Registers are currently set by BIOS, preventing flash access. One thing i want to ask about that: When i extract V1JV1X64.exe (Acer bios zip exe file) it extractes itself to %temp% folder with a BIN file, named isflash.bin This BIN file creates a platforms.ini file when i try to run InsydeFlashx64.exe (in temp folder) In this platform.ini file, password and clearcmos values are set to 0 Isnt it possible to correct that values 0 to 1 in isflash.bin file? I believe if they come with 1 value by default, it will flash password and cmos and will clear bios password... I tried to do that with a hex editor and flashed new bin file but it gave me an error "Invalid firmware image!!!" (i may did something wrong, i am a regular user, not an expert, but trying my best...) Am i wrong? If yes i am in the wrong way, tell me about SPI PGM, Whats the next? By the way, thank you so much for your efforts replying me...
Ok friend, don't use Capsulated Bios for Recovery It can brick your system !, so don't touch isflash.bin only way to use Capsulated Bios is by InsydeFlash ! The Backup Bios is only Bios Region so 4096 KB and without FPT is not possible to reflash ! Recovery works only using keyboard keys, so You haven't Keyboard and Recovery Mode don't start ! We have to ask to Serg008 and Thanh2h, may be They can help us ! I think that You can try using an USB Hub and Usb Stick and keyboard togheter on It trying if Bios listen Keys at start-Up to let work Recoery (but error 28 gives issue) ! You are sure that cannot Boot from USB Stick in Dos Mode to use FPT ? Regards
I can boot it DOS Mode, but FPT still gives me Error 28 if I use prr or prr2. I have Keyboard, I have a Lenovo Z50 Laptop. I know how to get into recovery mode but it doesnt flash. Is there a way to get a decapsulated bios out of the capsulated one to mod? Could you ask them? That would be nice because they don't know me and I don't want to annoy them
Hi BDMAster, I proceeded as it was written but I have been unsuccessful so far. When I start flashing it ends up with message PDR region does not exist GBE region does not exist Error28: PRotected Range Registers are currently set by BIOS, preventing Flash access. Any hints or tips, what to do to make the BIOS mod flashable and working ? Thanx for any advice.
