Language / layout
Set your device's keyboard to a Russian layout, then type Cyrillic here — the device sends key scancodes like a real RU keyboard. Works on Android TV, Linux, Windows, macOS. Use the button to toggle the OS layout.
Plain Latin always works. For Cyrillic prefer the Russian layout mode (reliable everywhere). “Unicode injection” is a best-effort fallback for emoji/other scripts.
Flash the device
Plug the T-Dongle-S3 into a USB port. Enter your WiFi so it can come online right after flashing, then press Connect & Flash.
Advanced
⚠️ If the port doesn't appear or connecting fails: unplug, hold the BOOT button, plug in while holding, release after ~2 s — that forces download mode.
