strong SRT 4930 hd problem

[mozaxpro]

Hi everyone..
I have a strong srt 4930 hd receiver and it boots showing zero channel but after 10 seconds it freezes and shows only a zero on it without the ability to use the the remote control.
I want to flash it with a USB but I don't know how and I searched a lot but found nothing. any help would be appreciated. thanks.

You can turn it on with other electronic devices such as smartphones. You try what I say.
