I tried to flash my Netgear DG834 Router Modem. I am now the owner of a brick. Is there any way to get it back to life again..
With my experience with Netgear routers, there is only one thing you can do and if that fails you're stuck with a brick.
However, before you do anything you should try to reset it with the 30/30/30 reset procedure. Essentially it goes like this:
1. Disconnect all cables except power and hold the reset button for 30 seconds.
2. Without letting go of the reset button, unplug the power, and then hold reset for another 30 seconds.
3. While still holding on, plug the power back in and hold the reset down for another 30 seconds.
After this, let go of the reset button and let it sit for 10-15 seconds. Then unplug the power again for 10 seconds and plug it back in.
Now, if the resetting doesn't work, the only chance you have is the TFTP method which is described here.
Actually, scratch what I said about being the only way. If you're really desperate, this could work as well. I haven't tried it before, but it seems some people have had success with it.
