Error Erasing MTD Block during firmware update. 3500lv2

I bought a router second hand that was running shibby's version of Tomato.  I wanted to wipe the router and update to the AIO firmware.  When I attempted to update the firmware it began fine, but then it suddenly stated "error erasing MTD block" and attempted to rebbot.  When it attempted to reboot it wouldn't completely boot up.  I have tried to reset it using a hard reset and a 30-30-30 but still just the power lite blinking green.  Any help would be great!
