I'm attempting to recover a DG834v1 that fails to boot. It started exhibiting the flashing power/check LED symptom after being powered down and up again during a site relocation. Prior to the power down, it was working. I attempted to use the Netgear Recovery utility and it appeared to successfully go through the motions of flashing a new image, but on reboot, the same symptoms prevail. I have tried as many images for the DG834G as I can find on the net, but to no avail. I am assuming that the upload works because the version numbers reported by the upload tool differ.
As the standard year warranty had expired, I opened it up, found an unpopulated serial interface (JP603) and wired it to a MAX232 chip as per the instructions for the v2 of the same router on this and a few other sites. Booting the router with a PC connected and a terminal session at 115200 8N1 gives me the following sequence of events every time:
1. internet link led (i) comes on orange
2. power led comes on green and internet link turns off
3. The following comes out the serial interface:

Download.
Copying download from b0017000 to b40200004. 5 seconds later, power and check leds flash alternatively green and orange respectively
This is the same for all versions of the firmware images I have tried. Trying to send keypresses has no effect.
Another note is that I have only ever loaded official Netgear images onto the router.
Anyone have any suggestions?
