I successfully flashed DDWRT to my router, but upon returning from holiday, someone has done something to it: I cannot ping it, log in or use the firmware flashing tool. All lights flash on and off every 2 seconds or so. It appears bricked!

Can anyone kindly guide me through the necessary steps to attempt recovery?

this will give you a idea how to get started.after you take it apart solder a 3pin header or wire to your router board header to the usb to ttl adapter and config putty and get something like this.

Powered on router.
Waited for "Autobooting" message in log.
Quickly typed "tpl". Got into the U-Boot command prompt.
Set PC IP to 192.168.1.100

tftpboot 0x80000000 ddwrt.bin
erase 0x9f020000 +0x3c0000
cp.b 0x80000000 0x9f020000 0x3c0000
bootm 0x9f020000


the ddwrt.bin will be the factory flash for your router,None of the ddwrt builds have the boot loader so serial flash it it will work i do the same with gargoyle.
I have unbricked the WR941ND,WR940n,wr841n.wr740n,useing these steps.also read these forms will help.
