If you are faced with the problem of an iphone that wont turn on either due to bricking or after you attempt resetting to factory settings / state, then try the following steps to get your iphone up and running.
1. Turn It On/Restart It
If you iPhone won't turn on, the
first thing you should do is check to make sure that it's not
off. To do this, just hold down the Hold button at the top
right corner on the edge of the phone for a few seconds. If
the phone is off, it should turn on. If it's on, you may get the slider that lets you turn it off. If it was off, let it boot up. If it was on, restarting it by turning it off and then turning it back on is probably a good
2. Press the Hold and Home Buttons
If your iPhone wasn't turned off or won't restart, hold down the Hold button and the Home button on
the bottom center of the front of the iPhone at the same
time. Hold them both for at least 20 seconds (there's nothing wrong with holding for 30 seconds or more, though if nothing has happened at that point, it probably won't). In
many cases, the silver Apple logo will appear and the phone will boot up.
3. Charge Your Phone
Again, this may seem obvious, but it's actually pretty
common. If your iPhone's battery runs very far down, the
iPhone won't turn on. That's because it's using its remaining
battery life to preserve your data and settings.
So, your iPhone could be refusing to turn on because its
battery doesn't have enough juice. In that case, plug your
iPhone into a wall charger or into your computer (plug it
directly into the computer; some USB ports on keyboards
don't have enough power to charge iPhones). Let it sit for
10-20 minutes. If it was low on battery and needed a
charge, when it's got enough juice to power the screen, it
will turn on and show you its charging status, starting with
the red battery icon.
If you suspect your phone ran out of battery but this
technique doesn't work, it's possible that your charger or
cable is faulty. Try using another charger or cable and see if
During this process, you may also want to make sure there's
no lint packed into your cable or the iPhone's dock connector.
This isn't a hugely common problem, but a lot of pocket lint
could interfere with the iPhone getting a charge.
4. Restore / reset to Factory Settings
If those options don't work, sometimes your best bet is to
restore your iPhone to its factory settings. This erases all
the data and settings on your phone (hopefully you synced it recently and backed up your data), but it can solve a lot of problems. Normally, you can just sync your iPhone and click the Restore button in iTunes, but if it won't turn on, you need a different technique:
1. Plug the iPhone's USB cable into the dock connector, but
not into your computer
2. Hold down the iPhone's Home button
3. Now plug the other end of the USB cable into your
4. This will open iTunes, put the iPhone into recovery
mode, and let you completely restore the iPhone.
5. Put your iphone in DFU Mode
In some rare circumstances, the issue might not be so much
that your iPhone won't turn on as that it won't boot up
properly. This often takes the form of the phone trying to
start, getting to the silver Apple logo, and then restarting
itself. This is most common after jailbreaking or when trying
to install an iOS update without enough battery life.
If you're facing this problem, try putting your phone into DFU
mode and resetting it.
Putting a device into DFU mode is similar to recovery mode,
but not quite as easy so don't be discouraged if you can't
make it work right away. Most likely your problem is coming
during step 4 so be very patient at that stage.
1. Begin by connecting your iPhone or other iOS device to
2. Turn off the device by holding down the sleep/power
button in the top right corner and the Home button on
the front button of the device
at the same time. A red slider will appear. Slide it to the
right to turn off the device. Alternatively, keep holding
both buttons even after the slider appears and the
device will turn off. Let go of the buttons when the
device powers down.
3. With the device off, once again hold down the sleep/
power and Home buttons at the same time.
4. Hold these buttons for 10 seconds. This is the crucial
step. Be patient and slow with your count. If you count
too quickly and let go before 10 full seconds have
passed, you'll enter recovery mode instead of DFU mode.
5. After 10 seconds have passed, let go of the sleep/
power button, but keep holding the Home Button.
6. The Apple logo will appear on the device's screen, but
keep holding the Home button until the recovery mode
warning pops up in iTunes. Then you can let go of the
7. If your device's screen is black, you're in DFU Mode. It
may appear that the device is turned off, but it's not.
8. If you're in recovery mode (indicated by a graphic of a
cable connecting to the iTunes icon) or have booted up
your device, repeat these steps.
Other means to enter DFU Mode include non-iTunes
How to Exit DFU mode
To exit iPhone DFU Mode, you can just turn off the device. Do
this by holding down the sleep/power and Home buttons
until the slider appears or, if you hold it longer, the device
turns off and the screen goes dark.
6. Proximity Sensor Problem
Another rare circumstance that can cause a problem with
some iPhones is a malfunction in the proximity sensor that
turns the iPhone's screen on and off when you hold it up to
your face to make a call. This malfunction can cause the
screen to be turned off even when the phone is on and not
near your face.
If you're facing this issue, it can usually be solved through
software, rather than repairing or replacing the phone. In
this case, hold down the Home and Hold buttons as outlined
above to restart the phone. When it restarts, the screen
should be working. If it is do the following:
1. Tap the Settings app
2. Tap General
3. Tap Reset
4. Tap Reset All Settings. This erases all your
preferences and settings on the iPhone, but won't
delete your data.
5. Confirm the reset. This should resolve the proximity
