    did you tried the official tool with official firmware?

      Yes, it was my second flash ROM.

      1) Finless 1.5 ROM. Flash OK. Sitck dead
      2) Factory ROM with factory (?) tools. Flash OK. Stick dead
      3.4.5.6) Other mixed options, including Mask ROM...no success...

      All the times the flash process went OK (like LOG I posted), but no results...

        Did you tried it in other TVs, and with other PSU (5V2A minimum).

        P.S. - daqui a pouco mais vale falar em PT já que a ajuda nestes fóruns (mini PCs) tem sido pouco dinâmica...

          Lourenço...LOL

          O problema é que a luz azul acende...e apaga-se logo.

          O unico "erro" que detetei ao longo de todos os flashes foi que nas instruções sempre diz que após carregar no botão de reset duas coisas deviam acontecer:
          1) O pc reconhecer o device - OK
          2) A luz apagar-se ao entrar em modo reset. Isto nunca acontece...O PC reconhece o device, mas a luz azul nunca apaga quando o stick está ligado ao pc via porta otg...isto é esquisito.

          Ontem desmontei o stick e chantei os pinos 8+9 da NAND, o pc reconheceu...mas a p*ta da luz azul fica sempre acesa.
          Só está acesa qd não preciso lol...

            probably it is better to keep writing in English as it may be against forum regulations (?).

            Mine doesn't turn on the LED at all. In fact, the first and only time I flash it I had to put it in the flash mode (pressing the hidden button that is, in fact, a VOL+ button - LOL - I wonder where is the VOL-) when it should have been recognized out of the box.
            The unit still switches the HDMI HUB (5-port) in my TV setup but noting on screen.

            Did you installed the driver correctly? (you should have a RK30 device in device manager) also, it seems that these devices are very sensible to the PC/USB ports - did you tried on other PCs? - I know I have (netbooks, notebooks, desktop PCs, ...) - also, try other USB cable (a branded one like SONY, LG, ... maybe with a ferrite core) the usb cable shipped is most probably crap.

            In your case I believe that you're going to be able to flash it. (hopefully)

              Tonight I'll uninstall the driver and I'll start (again) from the beginning.

              I notice that RockusbDriver.zip (link in apad.tv) could be different from Finless driver package.

              So I'll start again, but always with a doubt on my mind...wtf is GV20 ????

                The flash tool shows no errors so I doubt seriously this is a ROM flash issue. What the issue probably is, is you dont really have a stock ROM for this and none of the other ROMs will work on this unit.

                    I have no clue! This is the problem with some of these clone devices. Sorry...

                          No you're looking wrong at it - no external antennas. At least your seems to be one of the first units. In fact, initially, I've heard that GV-20 was the device that was cloned by others (and now it seems we have clones of clones)

                            In that case, my GV20 is what ? MK808 ? MK808B ? MK808B fake/clone ? I'm LOST....

                              I might be wrong but would say GV-20 was the first model and it is what you've got (or close). BUT, that don't mean anything because china manufacturing can be very imaginative in what they call their product and what they fit inside the boxes.

                              Your pictures are definitively different from my MK808.
