HLK-RM04 wifi shield factory reset?

Ok i have this HLK-RM04

it came with no catalogue or manual all threads about it are in Chinese after when i found the configuration webpage and changing it to client it wont connect and i t stopped board casting hlink wifi how could i reset to factory settings ?

after very long search i found an English manual

what does Trst means ? i don’t understand what i must do to reset it !

Trst=TimeReset is my best guess. Like a short press on the reset button on your home WiFi-Router just resets it, and a longer press (usually 10-30s) is a hard reset.

// Per.

Just curious, was this ever fixed? I am having the same exact issue and need to reset to factory default.
