I guess this comes a bit late, nevertheless:

Set a static IP to your computer:

Computer IP: 192.168.1.5
Net mask: 255.255.255.0
Gateway: 192.168.1.1

The way of putting the router in recovery mode is pressing the red little button for 15 sec, keep pressing it and then press with a pen the recovery button, keep pressing both for another 15 sec, release the red button, keep pressing with the pen until you get TTL=100 or the power LED blinks slowly (instead of fast blinking).

If Asus restoration tool does not do the job, try this in cygwin:

tftp -4 -m binary 192.168.1.1 -c put dd-wrt.v24-14929_NEWD-2_K2.6_mini_RT-N16.trx

Then:

mtd erase nvram
mtd erase ddwrt
mtd erase linux
reboot

Then it pings again with TTL=100 (it does this by itself).

Then again:

tftp -4 -m binary 192.168.1.1 -c put dd-wrt.v24-14929_NEWD-2_K2.6_mini_RT-N16.trx

After 5 minutes cut the power off from the router. Wait 10 sec and do the power back on.

Then flash build 21530 (choose reset to defaults). Then flash a recent K3.x build (don't reset the settings).

Basically, you should not ever reset its settings. If you do and gets bricked, do again what is written above.

For me I just hold the "restore" button for about 3 seconds while plugging the power in. Recently had to do it a few dozen times because it seems that in addition to not running `nvram clear` from the CLI, you also should not do "Restore Factory Defaults" from the UI, as that also hoses it, and to recover you have to do the `mtd erase` stuff.
