Did you check your security software settings? http://support.apple.com/kb/TS3125
iTunes has to be able to contact Apple during the downloading and installing process.

TS3297 how i can fix error 1015 when i restore iphone 3g ?

how i can fix error 1015 when i restore iphone 3g ?

You can't. Error 1015 occurs when trying to restore a jailbroken phone.
Jailbreaking your phone voids any warranty remaining with Apple and forfeits your right to any assistance from Apple including from this forum.
You're on your own. From what other people have posted, it's extremely unlikely you'll ever get your phone working again.

Activation issues are typically the result of a device that has been hacked or jailbroken.
If that is the case, no support can be provided here.

Yes. iOS 4.2.1 requires iTunes 10.1 or greater, which requires OS X 10.5.8 or greater.

My 3GS phone is now a brick thanks to itunes!
After being forced to upgrade my iOs because I of an app I decided to upgrade to iOs 5.
The phone is in recovery mode but every time I tried it
Now it is a brick that is going to the pollution pile.
So I am in the Apple Brick club.
Yes I did the typical, Win XP reboot a few times. Changed USB port. Tried different PC.
I have administrator access on my computer.
The phone is out of warranty. Is Apple going to charge me for something that their software did?
I have a copy of the ipsw but have no way of verifying whether the backup file is corrupt.

How to update your iPhone, iPad, or iPod touch

After update my iphone 3gs ios 4.1 to ios 5.0.1 could not active my iphone,

pls, help

I think what he means, is when you know how when you update your phone, itunes has to restore your last back-up back onto the iphone, or ipod, and it it wont let this person. If so, im having this problem myself, i lost all my contacts and data saved on one of my back ups because itunes refuses to restore my phone from before the update, my 3GS went from 4.3.5 to 5.0.1. I hope my problem is the same here, but i have no solutions.
Im not supporting the idea, but ive heard that jailbreaks can Force the iphone to restore, but thats only what ive heard. sorry if my problem isnt the same. and sorry i couldnt provide a solution :/

HELP: Error 14 when update/restore to 2.2

Hi,
I've been unable to update to 2.2. Each time, it errors out with error 14. I'm on Vista running 8.0.2. I can shift-restore to 2.1 w/o any issues. I'm also using the original USB cable, and connected to my Lenovo T61p notebook directly.. Also tried on another Dell notebook w/ 8.0.2. I've also tried deleting the firmware that is already downloaded in the Apple folder. None of these work. Please advice. Thanks.
Here's an excerpt of the log file:

Could not restore - error 1000

2009-01-17 14:47:18.545 iTunes.exe[13412:56c]: iTunes: Restore error 14

I've already tried deleting the firmware file per my original post. I don't believe it is trying to backup/sync at the same time. I can't be sure when I hit the UPDATE or RESTORE from 2.1 to 2.2, but once that failed with error 14, iTunes immediately said it is in RESTORE mode.
So, after that, I turned the phone off, press the HOME and POWER for 10sec and release the POWER button. This should put it in DFU mode. And then I click SHIFT-RESTORE and pick the firmware file. Same results, error 14.
When I don't do anything extra, just clicking RESTORE, it still results in error 14.
I can SHIFT-RESTORE to 2.1 w/o any issues though.
