So I had to update the xreal glasses and it turns out that the stock USB C – USB C cable doesn’t work very well on windows for updating firmware so here are the steps I followed to update the firmware successfully to version 1110

  1. Connect your Xreal Air to your pc using another USB C to USB A cable (it worked for me using a USB C to Mini USB adapter and then any USB A cable) and plug it directly to the PC, don’t use any dongle or hub and avoid using the stock cable
  2. Open Chrome (preferably on incognito mode) and load the update website (https://ota.xreal.com/en/air-update.html )
  3. Follow the steps to download the firmware, connect the Air and click on the MCU Firmware update.
  4. It should update without trouble
  5. Once you finish click on update DP Firmware
  6. It will say that it CANT CONNECT or THE GLASSES ARE NOT CONNECTED
  7. Unplug your glasses from the pc and plug them back
  8. Click OK on the popup and it will show the connection dialog
  9. Select your glasses from it and continue the update.
  10. Everything should be updated (at the time of writing the xreal firmware version was “air_07.1.02.201_20230228.bin”
