I got a SG9665GC in 2015 and have used it for a long time with a 32 GB card. August 2019 I bought a SanDisk 400 GB card, which didn't work at first, then I upgraded the firmware and formatted the card in the dashcam and it worked fine until yesterday. Starting yesterday, if I have the 400 GB card in, the dashcam just repeatedly bootloops (still works fine with 32 GB card though). When I plugged the 400 GB card into my windows computer, Windows prompted me to scan and try repairing, then it reported that the card was fine and I'm able to read files off of it. Plugging it back into dashcam still causes boot loops though. Maybe I need to reformat the card in the dashcam? But not sure how to do that given the boot loop.
