how to recover broken/damaged/bricked wrt54gl router

If you accidentally damage your wrt54gl, for example, by directly upgrading stock router with Standard Generic instead of Mini Generic (and then follow by Standard Generic), you can recover your router as follow.
  1. Download stock firmware from linksys's website.
  2. Using tftp to flash the firmware.  Execute these commands in tftp:
    > binary  > rexmt 1  > timeout 60  > put dd-wrt.vXX_XXX.XXX
  3. Hard reset the router: Power on + push reset button for 30 seconds, Power off + still keep pushing the reset button for 30 seconds and Power on + still keep pushing the reset button for another 30 seconds.

fail to determine the codename of the release

alt + f2
mount /dev/sdc1 /cdrom
alt + f1

This is a bug.  Debian installer expects files under /cdrom/.
