I tried:
1) Reset option 30 seconds
2) Removing memory card
3) Reflashing to new, old multiple times
4) Taking apart and reseating the camera strip to the board
5) Plugging into to pc and other power options
nothing seems to be working unfortunately.
Stuck Logo isn't serious and can be recovered.
Never remove or insert memory card while power is on or while power LED remains lit after disconnecting power.
Never connect power cable to Rear Camera port.
Never use USB2.0 500milliamp port to power A129.
Very common Startup failure is low voltage or Amps, troubleshoot with no other devices sharing the same power source.
Disconnect power for 1 min and notice the power LED, if it stays on for more than 8 seconds the Firmware file is corrupted, suggest downloading new copy from official website link. Always allow power to drain before touching memory card slot, the capacitors must drain fully. Remove memory card then try powering from 1Amp or higher power adapter or power bank then
connect power to camera side port without GPS mount connected and without Rear camera connected.
If the vehicle momentarily disconnects power to A129 during ignition you'll have to set Startup Delay to 10 seconds.
Troubleshoot indoors using known good power supply or computer USB3 port without other devices connected on same shared port.
Copy new binary firmware file to root of known good memory card, then insert in dashcam, then connect power, now wait 60 seconds, what brand/size card are you using? can you swap other cards?
Once past Logo screen and Dashcam is operating normally scroll to bottom Menu and FORMAT the memory card, then select DEFAULT Settings.
