Tried to flash multiple roms, Usb burning tool detect box ok and flash process finish without errors (100% success).
When connect to tv there is just logo and nothing else.
Logo changes according to rom that i flashed (Beelink, AlvaTech...) but cannot pass that.
Leave the box connected to tv half an hour but only logo remains, nothing changes.
Tried with SD card method but all the same.
There is no sticker with serial number on the back, but i will post some images of the board itself.
Maybe someone can recommend some rom or what else to try.
Thanks.
