I installed tomato on my router from original firmware using tftp method, and I successfully log in to web UI of tomato. Then I erased NVRAM (thorough) under Administration/Configuration/Restore_Default_Configuration, after that my router went into brick. Doesn't respond ping except the power up second, and UI also can't be logged in. I have a serial connector, but don't know what to do next step. Hope someone can help me fix it. THX@@ I would post any info I could get if needed.
