how to fix E71 error

Guys,

I turned on my XBOX 360 like after almost a year, and as expected, as soon as I turned it on, I got a pop-up for software update, and I promptly did it, but soon after my 360 turned on and I got a E71 error.

I tried the Towel trick, removed my HDD and restart, and I still continue to get the error. Can someone please help.

I am currently in India, and I bought my 360 from the US. When i spoketo MS customer service, they told they do not support international warranties and cannot fix my 360.

So I am left with no other option but to fix it myself.

Please let me know if any of you guys have faced a similar problem and have found a fix for it.

Thanks,
