I have a Linksys WRT-310n v1 that was previously running dd-wrt. I flashed the wrong TomatoUSB firmware (tomato-K26-1.28.9054MIPSR2-beta-Std) to the device; where I should have used the MIPSR1. Read properly, but clicked the wrong link from the download page. 100% my fault, but anyway, the damage has been done.
Attempted to TFTP a linksys firmware, but ping never works (even after 30/30/30 reset and then holding reset on power-on to get into recovery mode). Followed many guides, manually set my IP to 192.168.1.2, 192.168.1.25, 192.168.1.10, 192.168.1.100, etc. Manually added a static ARP table entry for the router's MAC address. Turned off firewall, antivirus, tried setting wired network card in 10/half-duplex as well as auto.
The router just sits there with the power LED constantly flashing. I can't seem to get it into recovery mode to TFTP the linksys firmware.
Is there anything I can do to rescue this unit? I'm not skilled enough to open it and go the JTAG/serial flash route.
