X99E-itx/ac bricked bios

Unfortunately that failed and eventually got stuck on "Processing Crashless feature..." staying at 0% I have now tried downloading the instant flash files for pretty much all available versions - 1.10,1.20,1.40, 1.50, 3.10, as well as 3.11a and 3.20 from the Beta Zone - without success either. To give you an idea what I tried: I formatted an USB stick to Fat32 and simply copied the unzipped BIOS file onto the USB, plugged it into one of the USB 2.0 ports on the back and turned the PC on. With the 1.10,1.20,1.40 (X99EITX1.40) and 1.50 (X99EITX1.50) file, the ASRock screen will show up  and after freezes , finally the computer simply turns off. Trying the same with any of the newer files (X99EITX3.10, X99EITX3.11A, X99EITX3.20, and later until 3.60) will result in the ASRock screen not even showing up. I'm completely out of ideas at this point and wonder if there's anything I've been doing wrong or if there is another approach I could try.

Completely odd. The revisions of BIOS you've tried are somewhat at odds with what your DL pages times/dates suggest.

Please reply back the model number of the motherboard that is silkscreen below the PCIe slot.

When using Internet Flash, it is recommended to put a USB flash drive into a USB 2.0 port on the board's IO panel, which will cause the UEFI/BIOS file to be written to the USB flash drive. That helps when the Internet Flash has a problem, and the board can recover with the UEFI file on the USB flash drive.

If you are unable to flash to any UEFI version, it is possible to replace the UEFI/BIOS chip. The chip can be removed (carefully!) as it is not soldered to the board.

You can get a chip with a UEFI version already on it from places like eBay, or directly from ASRock:

An unrelated but important detail, you currently are using a Haswell-E processor (correct?) but are updating to a Broadwell-E compatible UEFI version. That's Ok to do, but you must also update the Intel Management Engine (IME) software before or after the UEFI update.

We don't know what version of Windows you use, but use the IME version found on the Windows 10 64bit download page for your board. That is the Intel Management Engine driver ver:11.0.0.1158:

Try clearing CMOS before updating. Also make sure that the flash drive is blank aside from the BIOS update. If that still does not work try a different flash drive. I have an old 4gb flash drive that I use for BIOS updates because it always works.
