For your information, I upgraded a LK-9750 to firmware 7.0.7
Steps to upgrade to English firmware (for firmware version with language bug, i.e. korean menu only)
1. Use your PC or Mac.
2. Download your firmware here (all firmware support multiple languages).
3. Download qrlang.txt here
4. unzip all files and copy to the root of the larger SD card in your LUKAS dashcam.
5. eject the SD card from your computer, switch off your dashcam, insert SD card into your dashcam
6. turn on your dashcam, wait until the upgrade finished and reboot itself to normal operation.
7. you should see English logo during upgrade.
