I`m sorry, you have to call Service if TV is under warranty....

I decided to remove USB hack disk from download area due the reboot issue.
I`ll open download as soon as the next version without bugs is released.

One of users reported - he could execute custom script from USB over Debug mode.
I can`t confirm it could help you.

Just for case, give please the debug log from the start of TV until it reboots.

this unreadable output shows that something is wrong with your connection settings, speed is wrong or might bad cable. Check it.
I recommend you to use putty as terminal.
Copy/paste the output and use

I`m not the psychic and i can`t say from your photos is cable good or not
