Hi, I've just got a new Viper 4K V30 and I wanted to update it to OpenATV 7.0
I tried to flash the last image I found, but after two loading screens with OpenATV logo the screen become black and the box is unresponsive.
I tried to flash a new image then, but I can't flash anymore. On boot I press green button, the word UPDT appears, but nothing happens.
Can someone help me?
