Q: i updated my iphone 3G but why i cannot Restore the software?

What happens when you try?

I'll ask again... what happens when you try?

Was your phone jailbroken or hacked to unlock it?

Sorry, either find someone who can translate from English to your native language so you can answer the question, or post in your native language.

If you can't tell us what happens when you try to restore, including the exact text of any messages you get, there is absolutely no way we can help you.
