Debricking

See the second post in the above thread.

Reset

There are several methods to reset to default settings (clear NVRAM).
DO NOT "30-30-30" Reset ARM Devices!

Hardware reset button: When DD-WRT is running, holding the reset button for 10 sec.

DD-WRT GUI: Use the Restore Factory Defaults option:
Administration -> Factory Defaults (select radio button, then apply settings)
...or select the Reset to Default settings option from the Firmware Upgrade drop down menu:
Administration -> Firmware Upgrade (select the firmware file and "Reset to Default" from dropdown, then Upgrade

Telnet/SSH (CLI): Login and run `nvram erase && reboot` for Hard_reset_or_30/30/30#Erasing_NVRAM build 35770 and later.

Reset notes: In Feb. 2015 Kong announced a reset is required for certain upgrades as well. Do NOT restore an nvram backup as it will undo the reset.
