OK. TWRP restart needed.

Unfortunately, I created the problem myself. I made a ROM FF ZIP file with Ricky's amlogic customization tool, flashed by TWRP, and after restart box stopped on atvxperience logo (after boot animation|). Something can be done about it? Unbricking methods?

You must "Short the Pins" of the Nand Chip to get the device to be able to burn a firmware image through only using the Amlogic USB Burning Tool. I don't know why people try to flash firmware image's through TWRP, don't think there is any tool available that properly makes a twrp_firmware.zip that flashes and installs correctly.

Sidenote, try Nayam's new tool to modify firmwares, see this post: viewtopic.php?p=8372#p8372

Only using the Amlogic USB Burning Tool? What about sd card?

Unnecessary my fun with device = technical death. The computer can not see the box (USB Burning Tool). I do not know which pins to shorten, although I searched the entire Internet. I tried many pins combinations but no effect. The device probably to rubbish.

The USB Burning Tool can not see my box, so I will be grateful for answering a few questions. Should the USB Burnig Tool program see my box immediately after connecting the usb cable or also after shorten pin ? Should I disable the antivirus program? Can Windows 10 be a problem (driver signing is turned off)? Or maybe the problem is the length of the USB cable - more than two meters.

UBT program must be running, also USB cable must be connected, now you short the pins and you should see connection successfull message

Perhaps, check in device manager if WorldCup drivers are correctly installed.

Appropriate cable should be less then 1 meter long, USB 2.0 type and thicker.
