Just turned on my 360 after a few months of not playing and it now comes up with E71 error on the screen.
I have tried a few things to make it work already. I reset the hard drive and whipped everything off of it.
I downloaded the newest update and after the 360 resets it goes to a screen saying something is corrupted, so that does not work.
Is there a way for me to fix the E71 error or is it done for?

Console needs repair if removing the hard drive didn't fix the issue. Send it in or scrap it.
