My nephew has had an XBox 360 for years but recently it started getting the RROD red ring of death.
As a temporary measure he has been using his girlfriend's XBox - he took the hard disk out of his XBox 360E and put it into her XBox 360S and has been using that successfully for a few weeks.
We bought him another 360S - but when he started using it last week it no longer signs in.
He enters his email address and password, after a couple of seconds a "user <his username> signed in" message pops up at the bottom along with his avatar, but the cursor is still showing the spinning circle busy animation on the right.
Nothing else happens for ages, at least 5 minutes but possibly longer.
Eventually it then shows error 80072741, bit it can't be fully signed in so cannot play any games that he has downloaded. He can't even watch Netflix or other online things since he has to sign in to his XBox Live account first.
I think they need to work on having more descriptive/useful error messages, and actually showing the progress of what it is trying to do!
He has tried putting his hard disk back into his girlfriend's XBox - exactly the same issue.
I found this on MS website:
If you get this message and status code, it could mean one of these things:
Some Xbox LIVE features are not available because of system maintenance or a temporary Xbox LIVE issue.
You can't access some Xbox LIVE features because of a network configuration issue.
There might be a problem with your credit card. For example, your billing information might be incorrect, or your credit card might have expired.
A network test performs successfully.
All XBox live features are currently working (according to their website test).
Nothing has changed with the internet/network configuration, all other devices in the house still work.
The credit card has not expired and nothing else has happened to invalidate it.
My sister even rang up Microsoft UK (where we are) and after ages on the phone waiting and taking various options she was told that they "cannot help with Microsoft Live sign-in issues"!
We haven't been able to find much to help by searching, except someone suggested deleting his profile and cache from the hard disk - but he is very reluctant to do that since he thinks it will remove all of his saved games/progress.
thanks for reading, hoping that someone can help!
