How to fix some mysterious problems.

I jailbroke my iPhone 4s and everything was going fine. I decided to take it off because it was slowing down my phone so I went to settings and pressed reset all content and settings which got me into a boot loop. I've tried everything when I put restore on iTunes it just says error (-1). HELP!!

You will need to DFU restore your device.

Connect your iphone to your computer.

Open iTunes.

Now on your device press and keep holding "Home Button" and "Power Button" simultaneously till the device switches off and then switches back on again.

As soon as the "Apple" logo appears release the "Power Button" but keep holding the "Home Button".

Shortly afterwards iTunes should say that a device is in recovery mode and you will have a image of a cable plugged into your device on the screen of your device.

Your device will now be restored to the latest IOS.

I hope you have a recent backup of your data saved on your computer?

Tried a different PC

Disconnected all other usb cables, so only IOS device is attached?

Error one is sometimes a sign of hardware issues.
