Update firmware without remote controller on i3SIXTY 3

Need to update your i3SIXTY 3’s system firmware but don’t have the remote? No problem! This guide walks you through updating the firmware using just a USB drive and the display’s power button. This process is ideal for IT admins, installers, or anyone supporting i3SIXTY 3 displays when the remote is missing or unavailable. If your display powers on normally and you have a working remote, use the standard update method instead.

By the end of these steps, your i3SIXTY 3 will be running the latest system firmware. If the update process doesn’t start or you see error messages, check the troubleshooting section below.

Before you start

  • Use a USB 2.0 flash drive (SanDisk recommended), formatted to FAT32.

  • Download the correct firmware version for your display size (see the Files section).

  • Make sure the USB drive contains only the firmware file—no other files or folders.

Do not interrupt the firmware upgrade process

  • Do not touch the display (to avoid touch recalibration).

  • Do not disconnect power.

  • Do not remove the USB drive.

Prepare your USB drive

  1. Format your USB drive to FAT32 using your computer.

  2. Download the correct firmware file for your display size (see the Files section below).

  3. Copy the firmware file to the root directory of the USB drive. Remove any other files or folders.

  2. Insert the prepared USB drive into a USB port on the display.

  3. Press and hold the power button on the display.

The display will first update its main firmware, then automatically update the MCU. When finished, the display will reboot and be ready to use.

Troubleshooting

  • Update doesn’t start: Check that your USB drive is formatted to FAT32 and contains only the correct firmware file.

  • Display not recognizing USB: Try a different USB 2.0 drive (SanDisk recommended).

  • Error messages or failed update: Remove the USB, power cycle the display, and repeat the process. If issues persist, contact i3CONNECT support.

  • Remote available? Use the standard update method for a simpler process.
