Thx Scooter2014, i know this topic and i was follow it:

Android
Prepare/Create a USB disk Format FAT 32 8 GB or larger and copy Android install files.
Plug in USB disk with Android on it
As system boots tap continually F7 key
Small Boot Screen.
Use arrow key to select BOOT and select UEFI:BUILT-IN EFI SHELL, press ENTER
Unit will drop to shell and boot from USB commands will appear to run auto

Should see Shell > efilinux-eng.efi -f droidboot_b.img appear then away it goes.

but

1. no auto run
2. nothing happens in UEFII SHELL. there is no <efilinux-eng.efi -f droidboot_b.img> command in shell
so i cant install android


The same with Windows after created bootable usb stick.Box restarting and i see LOGO only over and over again.

I dont think that my box has been bricked but how to restore.
