The everyday reset on the RG405M is the standard Android factory reset in Settings → System → Reset options, which erases internal storage and returns the device to first-time setup. There is no simple on-device 'wipe' recovery menu like a phone; if the system is unbootable, the maker's method is to hold POWER + VOL DOWN + BACK to enter download (flash) mode and re-write the official image from a PC. A reset does not erase a removable microSD, but back it up anyway. This is a DRAFT for human review.

FAQ

How do I get into the recovery/flash mode?
From powered-off, hold POWER + VOL DOWN + BACK until a PC flashing tool shows a download/progress bar; from there you re-flash the official image.
Does a reset wipe my microSD card?
No. A factory reset clears internal storage only. Files on a removable microSD remain, but back them up before resetting just in case.
