1. RetroTINK-4Kの電源を落とした状態でSDカードを抜く。
2. RT4Kで使用するSDカードをパソコンのSDカードスロットに挿入する。パソコンにSDカードスロットがない場合は付属のUSBアダプターを使用する。
3. RetroTINK firmware websiteからファームウェアのZIPファイルをダウンロードする。
4. Extract the contents of the .zip file (the ".rbf" and "rt4kup.bin" files) to the SD card's root directory. Be sure to replace the existing "rt4kup.bin" file on the SD card, as this is used to determine which firmware to install.
   • If you intend to update via the RT4K's menu, do not delete the old *.rbf firmware file. If you do, you'll be forced to update via the Reset button method (see Step 6 below for how to do this).
5. Remove the SD card and insert it into the SD card slot on the RetroTINK-4K.
6. There are two methods for initiating the firmware installation. The RT4K installs firmware based on the "rt4kup.bin" file.
   • Option 1: Power on the RetroTINK-4K, then go to Advanced Settings > OSD/Firmware. In the Firmware update section, select "Check SD Card" to scan for the firmware file, then confirm that you want to install it.
   • Option 2: Hold down the blue Reset button on the back of the RetroTINK-4K, then power it on. The firmware installation will begin automatically.
   • If the LED blinks red, an install error has occurred. Check the files on the SD card and try again.
7. The RT4K will reboot for about 40 seconds, with the front LED flashing pink and then blue. Once done, it will power on again as normal with a green LED. You're done!

If you can't power on your RT4K or see the LED blink yellow, you've erased your current .rbf firmware file from your SD card. Please make sure both the .rbf and .bin files are on the root of the SD Card, and use the reset button method noted above.
