Reset iphone won't turn back on

reset iphone won't turn back on

Your post is extremely vague and several months old but hopefully this info can help others seeking a solution. I too had a problem with my iPhone (3gs in my case) not coming back up.
What happened -- I was using it normally and it rebooted and was stuck on the apple for a long time and wouldn't ever get past it. So I tried to reboot it by pressing power + home but it would just reset and never power off, and get stuck every time.
What I did to fix it -- I actually had to just remove the SIM card then reboot the phone. After it came back up I put the SIM card back in. It froze up for a short time after that as the service reactivated. But then it is back to normal now finally. Whew!

IPhone won't turn back on.

My iPhone 4S just randomly switched of on about 80% power and it won't turn back on. I've tried holding down the home and sleep buttons as well, but no luck. I put it into DFU made for recovery, and it did get discovered by iTunes, but the display doesn't turn on still.
It hasn't been damaged externally in anyway either.
Please help.

Sounds like a hardware problem. Make an appointment at an Apple store if there is one nearby.

My iPhone won't turn back on

I have an iPhone 5. The lock button doesn't work at all. I was going to restart it because it was being weird so I used the grey button thing on the screen ( I forgot what it's called) and turned it off. When I went to turn it back on it didn't do anything . Also I just took it off the charger so it was at 100%. How might I turn it back on?

You're going to have a hard time turning it back on if your power button doesn't work. Try putting it back on the charger. If it doesn't come back on, you're going to have to make an appointment to have it serviced at your nearest Genius Bar.

My iphone 4 fell off the charger and now it won't turn back on, it's stuck on the screen with the apple icon

HT4623 just updated my iPhone 4s to ios6, now my phone won't turn back on. The apple logo comes on and sits then shuts off. I have held down the home button and on/off switch several times to reset, but same problem persists.

Place iPhone on Wall Charger for at least 10 minutes. Then keep on charger and Reset, hold both home and power buttons until the iPhone begins to start, this can take about 20 seconds of holding both buttons while on charger. If still problem, open iTunes 10.7 on computer, connect iPhone to computer with USB Cable, hold both home and power buttons for about 20 seconds until iTunes recognizes iPhone in Recovery Mode, then click Restore button of iTunes. If still problem, try DFU Mode Restore, here are the steps. Open iTunes on computer. Connect iPhone to computer with USB cable. Hold both Home and Power buttons, after exactly 10 seconds release the Power Button, keep holding the Home button until iTunes recognizes iPhone in Recovery Mode, usually about 20 seconds time. If the iPhone screen is black, blank this is DFU Mode. Click the Restore button of iTunes. DFU Mode can be difficult to enter sometimes, just keep trying. DFU Mode is a black, blank screen with iTunes saying Recovery Mode. If still problem and there is Warranty or AppleCare make Genius reservation and take to Apple for resolution.

If wjosten's tip doesn't work try plugging it into a USB charger (not through your computer), wait about 30 seconds and it should come on. If it doesn't remove the cord from the phone and keep trying this. I've had this same issue and found a combination of the reset & charging cable tends to work. Sometimes it takes about 5 minutes for the phone to respond.
Best of luck.

Thanks for your help. I tried plugging it in but nothing happened, I actually still had battery power left. I was able to solve my problem by holding down the power and home buttons, which reset the phone and got it started again.
Thanks for trying

My iphone 5c turned off and won't turn back on. What do I do?

My iphone 5c turned off and won't turn back on. What do I do?

Try resetting the device: Hold down the Home and Power buttons at the same time and continue to hold them down until the Apple appears (up to 30 seconds). If the Apple appears, the reset is in progress, and the Slide to Unlock screen will display shortly.
Make sure the battery is charged. If you think it may not be charged, then plug the device into the charger and try resetting after 5 minutes or so.

My iPhone 5 just turned off and won't turn back on. It is fully charged

My iPhone 5 just turned off and it won't turn back on at all even when I put it on charge. It wasn't even dying but it just turned off. I need help ASAP

Try resetting it. Hold the on/off and home buttons together for about 10 or 12 seconds. Hlopefully you'll see the Apple logo (since you say it's well charged).

IPhone 5s shut itself off shortly after unplugging charger. Won't turn back on. Help!

I charged it for 15 mins, unplugged it, set an alarm, and 5-7 minutes later the screen was black and won't turn back on. The case/phone is still hot, and it still won't turn on after 2 hours. It hasn't cooled at all either, and my AC is blaring in this house.
When can I expect it to turn back on? That is, if it's even off at all.... Is there a reset button-pattern I can push to expedite the process? Is there anything I can do?
Should I just make an appointment for the Genius Bar? Help!

Turned off iphone 5 to preserve its battery and now it won't turn back on

Hello!
I've got my iPhone 5 16gb around 1 year now and today, i needed to preserve its battery life (97% remaining )so i turned it off. A few minutes in i needed to make a phone call but it won't turn back on. I've tried the recommended tips such as:
holding both home and lock screen button
DFU mode
Charging it
Nothing seems to work, i do not know whether the lock screen is broken or not or just whether its a battery or ios problem. Funny thing is that a few days before this incident, there was an 7.1.2 update so yeah idk. Please help. It will be a pain to buy another iPhone

Hey there iDopey,
It sounds like you are currently unable to turn on your iPhone on or it is on, but the screen is black. First determine if the unit is on but has a black screen with this:
Display has no backlight or dark screen
Toggle the ringer switch to see if the unit vibrates. If it does, it could be that iPhone is getting power, but is not displaying any image.
Try turning iPhone off and then on again.
While connected to the iPhone charger, try to reset the iPhone.
If the low-battery screen appears, charge the iPhone.
If this is the case follow the last step in this post. If not, then move on to this section:
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.

IPhone 4 turned off and won't turn back on.

My iphone was fully charged. It turned off by itself and it won't turn back on. I tried connecting it to my charger but it won't turn on. My lock button is broken so I can't hold the home + lock button to turn it back on. What can I do?

Get the lock button repaired. You need to reset the phone, which requires a functioning lock button.

My iPhone 3gs just randomly turned off and won't turn back on

I was just using my phone, and nothing happened. As of lately picture mail, and videos have been sending as a text message to other iPhone users even while connected to wifi. My phone just randomly turned off and won't turn back on. I just got it in July so its not very old and I have the hard protection case on it. Is there any way that I can reset it or something?

Hold the home and power button down at the same time.

My iphone 4 was acting up so i turned the fully charged phone off and it won't turn back on

my iphone 4 was acting up like th escreen wouldnt respond to my tough or the home button

and it won't turn back on
the screen did she the apple logo like it was about to power on but then it went black and hasent done anything since
i have plugged it in to my ocmputer and the wall charger and have had no luck

Plug it in to power for at least 15 minutes.
The, try resetting your iPhone by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.
