Brand new R7000 out of the box. Log-in to it and try to upload the dd-wrt firmware. The status screen says it's uploading and the progress bar move accross the screen, but it never completes. After waiting 10+ minutes it still has the same status. I'm able to refersh the page and try again, but for some reason it's not actually updating the firmware.
What can I do to fix this?
Which firmware you presently have in your router? Which dd-wrt firmware are you going to flash?
Go to kongs site here.

read the read me file.
It tells how to go to dd-wrt from stock & how to revert.
