How can i unblock my internet and my xbox live on my xbox 360?

Ive had this problem too my xbox live account was blocked soo i unblocked it by changing the windows live ID password

And after i did that I got on my xbox 360 and punched in my email and password and it said Sorry, Xbox LIVE profiles can't be downloaded right now. Try again later. 80070026." PLEASE HELP

It depends on how fast your internet connection is. The internet explorer with my internet speed can almost keep up with my laptop. The Xbox 360 and Xbox 360 slim are going to operate at the same speed though

No I never answered my own question. If you read carefully, I said I know what to do to unblock somebody. Then I asked how can I unblock somebody when we've blocked each other? This means I explained that I know how to unblock somebody when he hasn't
blocked me. This means things are harder to deal with when we've blocked each other because if I send him a message, invite or friends request, he won't get either of them so that I can unblock him, same thing visa-versa if he tries to unblock me. I was
asking if there's another way to unblock somebody when he's also blocked me, such as, is there a block list for me to unblock him from or can I unblock him by contacting Xbox Live?

first we need to know exactly how the services blocked. Please provide error codes in as much detail as possible

I have my XBOX 360, my friends brought over theirs, now no XBOX 360 connects to the internet. Not a single XBOX 360 can connect to the internet at my house.
