[EDIT]
Resolved, She's back from the dead. Details below in my last post. Still extremely happy with this box and I hope Android 9 will do as well as 8 did. Ematic was very helpful and even offered to update the box for me.
My Jetstream 4k (AGT418) has finally died. It refuses to boot, flashes the blue led for a second or two then goes back to red. Anyone have advice on how to resurrect this box? It's been good to me for a long time and hate to see it die this kind of death. I've tried using the reset pinhole between the USB ports - does nothing. Wanted to crack her open but didn't find any obvious screw holes, do the halves just snap together? Tried to connect with ADB via IP address but that failed too - I'm not sure if ADB was enabled or not.
Maybe you can check the power supply by using a different one.
