Tried this and without any luck, and currently on the phone with support. Is CTRL / ESC the only two keys or is there other keys to be used? Does the USB drive need to be bootable? I've even tried to boot off my Windows 10 recovery drive without any luck.

3,6 blinks means "Recovery image not found" on the hard drive. So your only option will be recovery from USB.

Did you follow the instructions to reformat the USB stick as FAT32, copy the BIOS file onto it and rename that file as BIOS_IMG.rcv ?

You need to connect the USB to the PC before you power it on, power on, and press/hold both Ctrl and Esc until the recovery page appears.

1. Keep trying. Sounds like it's not completely bricked because it knows it needs a new BIOS loaded.

2. Follow the directions.

3. Not until BIOS is fixed.
