To ensure successful Modified Firmware installation follow the 10 Step Guide above. Consider always using a small 16-32 GB FAT32 partition MicroSD card which has been erased or recently formatted for all Firmware Updates. Larger 64-128 GB memory cards formatted as FAT32 work the same. Always use a stable power source and do not interrupt the 60-70 second update process. If the Update fails erase or format the memory card and load official firmware for recovery. Remember to Reset Default Settings after all updates.
Drivers in hot climates/seasons should avoid running Dashcam at 60fps and consider using only 30fps to reduce internal heating. In extreme temperatures under full Sun it's advised not to use Parking Mode for hours which can exceed 70C internally even with stock firmware.
A129 Duo owners must be aware enabling WiFi not only generates extra heat but also reduces bitrate to 8 Mb/s in dual camera mode decreasing image detail. Always disable WiFi setting before driving for best quality.
When using 25 Mb/s bitrate or higher suggest setting Loop Recording at 2 mins to prevent video file size from exceeding 500 MB and prevent file corruption on slower memory cards. If possible use faster 64-128 GB U3 write speed memory cards.
