Hello, guys!
I tortured mine a little bit too much, apparently... It gave up...
So, now it seems I may need the following:
-Download HiTool (tool for rs232) here: https://mega.nz/#!0zRERTAC!HbM…bmI1Uo7D9BcWFDWheGCAQq4GA
A newer version 5.06 is here: https://archive.org/download/HiToolSTB5.0.6
You need the appropriate cable and for this box the connectors are on the motherboard itself, so open it up and connect only (my case below: https://www.adafruit.com/product/954 ):
grd (black)
rx (white)
tx (green)

H9S has Hi3798MV200 Main chipset
These settings and files might not be for your machine!!! It seems like a lot of experimenting should go on, as I could not see anything PRECISE and EXHAUSTIVE on the net... It seems I must dig into this...
