VIOFO-Support, perhaps you had to be more clear in your last post that the firmware you uploaded in there, is
NOT new, and has
NOT been specifically built by VIOFO recently to address the issue with random loss of settings, although I can see by the likes of your post that it has most certainly been taken that way by some users.
The reality is that the firmware version you uploaded above, is the fairly old test firmware v2.6T, build 20220215, which has been made available by VIOFO to the users out there long time ago.
The feedback I can give you right now is that this firmware version actually does NOT fix the settings loss issue. That has been reported by at least one user at the alternative forum, who had that version installed when it was first made available, and still reports periodical resets of the settings to their factory default values.
Sorry for me having to be a bad news messenger.
