Bricked my R7800?

I was having wireless speed and reliability issues with dd wrt so I decided I was going to go back to stock firmware or maybe to a different firmware (but back to stock first). I was running kong's build and these are the instructions: "Flash R7800-factory-to-ddwrt.img build from Netgear firmware. Once dd-wrt is running you have to use ddwrt-netgear-R7800.bin to flash future updates." So I downloaded the ddwrt-netgear-R7800.bin and flashed it from the existing dd wrt. Now my router has solid amber power led with the lan port showing traffic when my PC is connected. In that state it is completely unresponsive and will not take pings, telnet or any communication. If I put it into router management mode (hold reset on boot up until power led flashes constantly) and I make my PC have a static IP I can then ping the router. I get ttl=128 though and tftp2 has not worked at all. Telnet also does not work when the router is in this mode. I'm stuck and don't know what to do at this point. Am I going to need to use serial or jtag? Is there any other ways I can fix this? Thanks for any help in advance!

I know I'm a few days late on

I know I'm a few days late on this and I hope you got help, but if not here are some instructions

I never had luck using a TFTP GUI for this, so use the TFTP command in your Windows command prompt like this  tftp -i put dd-wrt.vXX_XXX.XXX

change the dd-wrt filename to the correct file name for what you are trying to flash.
