Serial Recovery
Misflashed units may send out BOOTP requests upon power. Using a BOOTP+TFTP server (I used this one on an old XP machine), you can assign it an IP and give it a firmware file to reflash with.

No success was had using the HTTP emergency flash recovery ("Wrong Image File is Selected!"), even after going through all the voodoo recommended here.

For debug solder console at Router PCB (TX-RX-GND) to view system messages while upgrading firmware.

Connect Router console over COM-USB adapter to PC USB.

Run HyperTerminal or Putty to communicate with Router. Select port speed 38400/8bit.

PowerOn Router. When booting stops, remember MAC address of router in console.

Remember, you can not solder console and try use MAC printed on the bottom of Router. But Attantion! Last digit of printed MAC usually grater by 1, ie if console prints 27, paper stick and web admin interface says 28. This bug not fixed in all FW (2.5 too). You must use paper-stick last digit minus 1 = console MAC last digit.
