Hi!...my 49225T-HN keeps switching to PAL by itself, loses all PTZ presets, and the time zone switches over to Beijing?!...Anyone experience this odd behavior? I don't have any ports open....when checking the log around the time this happens the only thing I see is "HOT SWAP"....and the microsdhc card seems frozen because I'm unable to reformat it through the browser interface...
is there any other way to force a reformat of the card?...I can tell the card is frozen because the storage numbers don't change.....is there another older firmware maybe I should flash back to?

Here's my current firmware:
SD49225T-HN
System VersionV2.800.0000000.4.R.R4.2510.9A.NR, Build Date: 2019-11-05
WEB VersionV3.2.1.810588
ONVIF Version18.12(V2.4.5.729857)
PTZ VersionV2.301.0000000.22.RHNZ_190923_33333


FYI I've tried total reset to factory and re-flashing of this particular firmware...this last time it went about 4 days before reverting back to this messed up situation.
