My asus rt-n16 stopped working after firmware upgrade!!!

My 2 months old asus rt-n16 was perfectly until yesterday night when i uploaded to latest firmware Version 3.0.0.4.260 from
Version 3.0.0.4.220. I was upgrading wirelessly, it upgraded successfully after which it said to reboot the router manually. After i did that router stopped working. Now the power led has started blinking. I m unable to connect to it. I have tried putting it in rescue mode after which i tried restoring it via asus firmware restoration utility, but after i start the power led is permanent or i does not light up at all. After it uploads firmware and it does recovering image, after 100% it says unable to connect to wireless device, plz check if it is in rescue mode. i have tried this like 10-15 times but it fails, either power light is permanent or it does not light up at all.

I put the router in rescue mode after pressing restore button for 5 sec and then connect power.

I have also tried 30/30/30 reset but it also fails.

I have tried calling asus fools to get foolish answers to make me fool.

Plz help

P.S - I have never installed any 3rd party custom firmwares.
