Hi, i upgraded my bios to the latest beta version this morning and it has sent my pc haywire i keep getting bsod left right n center now.

ive set it back to default in bios and removed the battery, Qflash and @BIOS from app center but it tells me the mobo is protected from using this bios.

i want to try use the ftp dos-z87 way but after following the instructions to the letter i get an error saying please remove media or bootable something is missing please restart. what am i doing wrong cant find any guides or step by step on using ftp dos at all.

pls help
 
You can press F8 inside bios or END i think on boot up to enter the flash utility.
Just put the bios require on a usb stick.
 
It will not allow you to downgrade using Qflash or @BIOS it fails to re flash saying "this motherboard is protected from using this bios" I tried flashing the bios from a bootable flash drive using Efiflash but it keeps telling me the bios failed to flash.

Ive been trying to flash using ftp_DOS-Z87 but i cant get it to work following the guide i found all i get is boot manager is missing when trying to boot using ftp_DOS-Z87.

im lost now id really appreciate it if someone could help me with this

cheers

Much appreciated, its had me preoccupied all day trying to fix this!

Before flashing i had a rock solid overclock of 4.4ghz albeit 1.295v 70.c-82.c for everyday use and heavy gaming. Now it just BSOD when stressed even ater upping to 1.3v Gigabyte recon the user cannot reflash a previous bios?
 
you can flash back and forth to any bios version,but on some boards and certain bios's there's a certain way to do it,might be with flash efi im not sure
 
Try in Windows (x64) with:

FPT-Win64-Z87

or try to kick up Backup BIOS.

Edit:
Checked ftp_DOS-Z87 file and found that is in order.
Did you place renamed "bios.bin" file and unziped files from ftp_DOS-Z87 to your bootable USB stick?

sorry guys been out working all day.

Yes i tried ftp_DOS-Z87 and placed the renamed bio.bin file in but when trying to boot from flash drive it says boot manager is missing. Im not sure if it has anything to do with transferring the files to flash drive as it asks me if i want to copy or replace 2 files AUTOEXEC and MSDOS.SYS even when the flash drive it empty and after formatting.

Ive never had to flash a bios before using this method so i could be doing something wrong but definitely followed steps to the letter so im at a loss, how do i use the
FPT-Win64-Z87

cheers
