use 'mtd' if its bricked by DD-WRT:

  1. Connect the router to a pc with an installed webserver providing the orig fw. 
  2. Reset to defaults may be useful. 
  3. ssh to your router 
  4. cd /tmp 
  5. wget http://yourpcwithwebserver/tp-link-wr1043nd-xxxxxx.bin 
     Attention! some firmwares containing "boot" in the name need modification - see scroogle!
  6. flash it via mtd: 
     mtd -e linux -r write tp-link-wr1043nd-xxxxxx.bin linux 
  7. Take a nap or do something else. 
     Be extra careful and read the mtd manual and the openwrt wiki for wr1043nd.
