hi... i have the POHD mini 2 and tried upgrading the firmware yesterday.. unfortunately, the upgrade just stops after the progress bar reaches 75%.. i left it for about an hour and still is not moving.. the thing i did next was to disconnect it from the power source (turned it off).. i have downloaded the other firmware versions but all are having the same issue... either stops when it reach 75% or worse right after 50%...

and now.. when i simply turn on the POHD it just shows the logo and hangs there... appreciate any help on this...

TIA...
