Amazing all you guys hacked on this thing... on my device i got stuck at the Copyright screen and does not respond to anything, i've updated the firmware, replaced the elgato binary modified licences and still can't pass that screen, had anyone came across this problem and might have a clue on how to fix it?
Thanks!

The symptom is not specific. It's probably the "elgato" fails to initialize (possibly due to some hardware problem). Try to gather more information (messages, logs, diagnostic web pages* ). Despite the UI is not started the device still can be accessed through the Ethernet and console ports.

* The ones you gеt by accessing the device via http.

Hi @kirill_ka yes, i can access via telnet without a problem, the web interface is unstable for me, sometimes work, sometimes doesn't and when it works it does not log in.

if i give it a ps aux i get this

but the fault is still the same. device stuck at copyright screen, no web interface and no remote access app response.

Thanks

In case my box is completely dead i'm using it to run Doom.

well on a closer look running elgato via telnet i found that i have license problems of which my elgato.lic is completely missing, replacing with a generic one from this post does not help since my hostID is other. is there a way to recover the hostID?
