ordinarily, if you want to reinstall os X on your iphone, you just plug it into your computer and click “Restore” in iTunes.

Restore

However, restoring works only if iTunes recognizes your iphone. if that’s not happening, then recovery mode is the answer. Recovery mode lets iTunes know that the iphone is ready to be restored.

Restoring your iphone puts it into an almost completely factory-fresh state that includes the erasure of all data, including songs, videos, contacts, photos, calendar information, and any other data that was added to your iphone after its purchase. Because the loss of all your data can be inconvenient at best, restoring should be your last resort after trying any applicable troubleshooting techniques.

The only more drastic restoration beyond restoration is DFU (Device Firmware Upgrade) mode.

At times, you might want to use restore mode even when you’re not restoring. For d example, you may also be asked to enter restore mode by some hacking applications, because it puts the iPhone in a state where it waits for an application to talk to it, whether that’s iTunes or a less oficial app. And you can back out of restore mode easily. entering recovery Mode

There are a couple of ways to get into recovery mode:

1. Make sure that your phone is off. if your phone is working normally, just hold down power for ive seconds and then slide to turn off. if your device can’t boot or is hung, you’ll turn it off by holding power and home until it powers off.

2. hold down the home button.

3. connect it to your computer via UsB.

4. keep holding the home button until your phone displays a screen, then let go.

Exiting recovery Mode

If you change your mind about recovery mode, it’s easy to get out of with a hard reset. if you just leave the device for a while, it will power down, at which point you can simply turn it back on.

To speed things up:

1. Disconnect the iphone or ipod from the computer.

2. hold down the power and home buttons until you see the boot logo.

3. When you see the boot logo, let go.

It’s almost guaranteed that within your irst week of iphone hacking you will think you’ve “bricked” your phone. Luckily, it is very easy to ix. When all else fails to bring back your iphone’s functionality, look to the Restore function, either in recovery mode or DFU mode to solve your problem. This trusty technique should ix almost any imaginable hacking- or non-hacking-related iphone issue.

Fully restoring your iPhone to a factory state (including irmware) is called d virginizing. Restoring an iPhone, iPhone 3G, or iPod touch in DFU mode with an Apple-provided irmware image is all you usually need to do to virginize your phone.

Reinstall everything with Device Firmware Upgrade Mode

in the process of hacking your phone, you may get into a state where you just can’t get the os to boot. or you may get errors when attempting to restore your device. or you may be trying to unlock your phone and you need to replace not just the os (as in jailbreaking) but the bootloader irmware as well. DFU mode performs a similar function to restore mode, except that in DFU mode, the iphone never even tries to boot os X. it’s kind of like booting a pc off a restore disc, which then replaces your os with a pristine installation.

More likely, though, you’ll be trying to do something clever with your phone, and the instructions for that clever feat will ask you to enter DFU mode.

For all of these situations, DFU mode is the troubleshooting mode you seek. in DFU mode, your iphone never gets to boot to Mac os X. instead, it sits there waiting to have its memory and Bios completely erased and rewritten.
