Hello there.
I have the Asrock Z77 Extreme4 motherboard and I have updated the bios because my motherboard does not see any running hdds (v2.90). With the new bios and ssds, when I connected the hdds while the system was running, the LED on the motherboard gave the A2 error. I've taken the previous version of the Asrock site, L2.21 version number bios (bios over instant flash with) I waited in half was expected to wait but I was not completed. Now when the PC turns on F9 error, there is no image on the screen, when I insert the USB, the image comes up and the Uefi Recovery screen opens, but it comes down to the quarter and freezes there and doesn't let me do anything.
I tried to recover;
Clear cmos key on the back of the motherboard, flash memory with ms dos on autosetup flash, motherboard cd, bios battery disassembly etc. none of them unfortunately did not work.
Sorry for bad english.
