[plemans]

1. use caps lock appropriately. tough to read when everything is capitalized and I feel like your shouting. 

2. What led is yellow? 

3. power dying during an upgrade can be an issue. 

You can try recoving it with tftp or nmrpflash.  

are you on windows? if so, follow this guide

just make sure you enable tftp

and here's a video walk through using a tftp client. Use the built in one for windows 10 though. the video is more of an example of how its done.
