Where oh where did I go wrong ??

I have a WNR3500L I wanted to put Toastmans Tomato on.

I did my homework and got everything ready.

Did a 30-30-30 and flashed wit dd-wrt min. Did another 30-30-30 and ddd-wrt came up fine.

Used the dd-wrt mini for a day and it worked well.

Downloaded tomato-K26USB-1.28.7498.1MIPSR2-Toastman-RT-Ext.trx and changed the extension to .bin

Did a 30-30-30 and upgraded to Toastman via the dd-wrt mini software

dd-wrt said sucessful upgrade, did another 30-30-30.

When the router finished booting up (the boot light sequence looked normal to me!) I was unable to connect to the router.

A release /renew didn't help. Another 30-30-30 didn't help. An ipconfig shows no ip address issued by the router.

Am I bricked? Where did I go wrong? I was careful to follow all directions carefully.

Any chance of recovery without going the usb cable route ?

Thanks
