When you have troubles with updating your xbox, take out the harddisk and start the update. Put it back in and it should be working.
That is a good question! I think they will stop making games for the xbox 360 and ps3 because of the ps4 and the xbox 720. They already stopped making games for ps2 and xbox. i have an xbox 360 so even i'm not sure weather to keep xbox or get xbox 720.
You can leave your Xbox 360 on as long as you want. But doing this make your Xbox overheat.
take it to a game shop and get them to clean it
You can hack it if you want to, but the x-box might stop working or it won't stop working.
if it is not working, take it out of your XBoX and blow it and rub it on your shirt.
Take it to be repaired or buy a new one
Go to Xbox.com or call 1-800-4MY-XBOX and take your credit card information off the xbox or just take the xbox's power chord away and ground him or her
How did it stop working? If its 1 red light flashing, you can send it in for free if you've had your xbox for less than 1 year, if its three red flashing lights you can send it in for free if you've had your xbox less than 3 years. 1-800-4myxbox i think is the phone number.
long enough
It depends if your xbox is fast or slow!
about a hour
Nope. There is no problem for someone playing the Xbox 360 live. If the bandwidth is being took over by him playing on the Xbox, you will need to sort out something with him.
