Black screen after failed firmware

[pro100umarchik]

Guys, who fumbles for android firmware? In short, I flashed Samsung through the Odin program, and almost at the end of the firmware, the computer passed out and the phone "grimaced". Just a black screen and no inscription. Maybe someone faced this, and do you know how to solve this garbage?

Try flashing your phone again, but this time using a more stable, reliable computer to be running the Odin utility on.
Can you reboot your Samsung phone back into Download Mode?

Попробуйте еще раз прошить телефон, но на этот раз используя более стабильный и надежный компьютер, на котором будет запущена утилита Odin.
Можете ли вы перезагрузить телефон Samsung обратно в режим загрузки?

Я ничего не могу сделать. Сначала был один ползунок посередине экрана, а теперь ничего нет, на подключения не реагирует и кнопочный запуск.

I can't do anything. At first, there was one slider in the middle of the screen, but now there is nothing, it does not respond to connections and button starts.

This is why firmware updates on any device some with warnings not to disconnect or shut down part way though, and why they won't run if the phone battery level is too low. A firmware update requires overwriting the existing firmware, and hence if you interrupt it at the wrong point there is a risk of something vital being rendered unusable.

Try charging it for a few hours, just in case the disappearance of this "one slider" is due to the battery running down while you've been trying to recover it. But if you can't get it into the bootloader/download mode your only option will be professional repair: a workshop with the correct equipment can probably get it going again (as long as there's no physical damage, which isn't what this sounds like).
