Before i had version F20b which was perfectly fine and no problems at all.
ok, i found a way to downgrade to previous version, so works fine now
you need FPT Z170 Tool for DOS (with bootable USB)....https://www.mediafire.com/?p66jhts7cfi26y8-download this first.-then make bootable usb stick with , in my example "rufus".-copy those files from link above to usb stick + bios file you want to downgrade.-i have used backup file (saved old bios bin) which is already named "bios.bin", otherwise rename original downloaded bios file to bios.bin.-boot from usb (bios settings)
I see, the only difference was that i have copied bios.bin to usb stick, which was created before upgrading to newer version, so, it was saved-backup file of older bios which was already named bios.bin.
I tired to downgrade bios F20 and now my PC won't bout.. I did the steps but was it right to put f5 file I wanted to flash to bios.bin, or should I put f20 to bios.bin? Really shouldn't play with these settings..

Really shouldn't play with these settings..Hi !After you have created bootable USB stick with , in my example Rufus,copy all files inside FPT Z170 Tool for DOS directory to USB stick , then copy also bios version you want to install.For example if your bios version is named "Z170D3H.F20" rename it to bios.binIf you want to downgrade to F5 version , then rename Z170D3H.F5 to bios.bin and put this file to USB stick where are also other files located. This is example for my motherboard model.Then boot from USB stick and downgrade should start automatically.You still have option to install F20 version back in BIOS , if computer won't boot. But ofcourse you'll need that bios file on your USB stick to do that or if it's located elswhere (external hdd...)I mean original downloaded file, for example Z170D3H.F20.I hope it helps.
