R7450 Brick?

[Sboda2012]

I tried to update the firmware this morning and it appears to be corrupted. Power light only blinks now. I have tried for 3 hours to flash it with tftp but that fails out as well. Has my router bricked? Hate to go buy a new one especially if this one can be fixed.

I suggest contacting support if the router is still under warranty.

Sometimes it takes a few attempts as its a short window when you use tftp. I usually use the windows built in client successfully. 

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.

and if that doesn't work, you can try using nmrpflash
