The AHM27292U will present a serial console after boot, the dmesg

sudo picocom -b 115200 /dev/ttyACM0
And issue the command: firstboot && reboot now
and confirm y
in the console:
root@HaLow_STA:/# firstboot && reboot now
This will erase all settings and remove any installed packages. Are you sure? [N/y]
y

Wait around 3~5 min till the reset process finish.
