HT4972 My ipods screen is black and wont turn on unless plugged into the wall

My ipods screen is black and wont turn on unless plugged into the wall not the computer but when i plug it into the computer and put it in DFU mode it wont restore there is an error 3194 and error 1602 and nothing i do helps

Here's what I found about error 1602:
Error 1600, 1601, 1602: Try the following steps to resolve this error:
Ensure proper USB isolation troubleshooting has been performed, and test with a known-good cable.
Follow the steps listed for Error 1604.
This error may be resolved by disabling, deactivating, or uninstalling third-party security, antivirus, and firewall software. See steps in this article for details on troubleshooting security software.
Error 1603: If you receive this error and the iOS device is not automatically placed into recovery mode, it may be necessary to do so manually. Refer to iPhone and iPod touch: Unable to restore for steps on placing iPhone into forced recovery mode. Also, remove the IPSW and attempt to restore again. If you do not want to remove the IPSW in the original user, try restoring in a new administrator user.
Error 1604: This error is often related to USB timing. Try changing USB ports, uninstalling and reinstalling USB ports, and other available USB troubleshooting steps (troubleshooting USB connections, device not recognized properly, computer won't recognize a FireWire or USB device). If you are using a dock, bypass it and connect directly to the white Apple USB dock connector cable. If the issue persists on a known-good computer, the device may need service.
This device is not eligible for the requested build: Also sometimes displayed as an "error 3194." If you receive this alert,update to the latest version of iTunes. Third-party security software or router security settings can also cause this issue. To resolve this, follow Troubleshooting security software issues.
Downgrading to a previous version of iOS is not supported. If you have installed software to perform unauthorized modifications to your iOS device, that software may have redirected connections to the update server (gs.apple.com) within the Hosts file. First you must uninstall the unauthorized modification software from the computer, then edit out the "gs.apple.com" redirect from the hosts file, and then restart the computer for the host file changes to take affect. For steps to edit the Hosts file and allow iTunes to communicate with the update server, see iTunes: Troubleshooting iTunes Store on your computer, iPhone, iPad, or iPod—follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > The hosts file may also be blocking the iTunes Store. If you do not uninstall the unauthorized modification software prior to editing the hosts file, that software may automatically modify the hosts file again on restart. Also, using an older or modified .ipsw file can cause this issue. Try moving the current .ipsw file, or try restoring in a new user to ensure that iTunes downloads a new .ipsw.
Error 3194 is also seen when somebody is trying to restore jailbroken devices.

Iphone 4s wont turn on unless plugged in

HHEEEELLLPPP......only bought the phone in Jan 12. Got iphone 4s. I havent used it or had it switched on for few weeks...then today tried to turn it on but it wouldnt...thought battery was low so connected to lap top but it didnt do anything. So i plugged it in to power supply and it comes on and said battery was almost full (86%) it kept turning itself on/off then as soon as unplug it it turns back off.
I managed to get it whilst plugged in to laptop to start restoring it but then it stops with error code 1602.....my iphone is now in recovery mode but still doesnt switch on or anything when plug into laptop until i hold power/home buttons together.....and comes on when plugged into power plug.
Any idea wat problem could be or how to fix it????

was kinda hoping would be able to get it sorted without doing that as there isnt a store that close to me :-/ ive booked a call back so hopefully they might be able to help

My 4month old Macbook pro wont turn on unless plugged in, but remains on after unplugged.

I got a brand new macbook pro 4months old. What happens is it does not turn un unless it is plugged in when I unplug it though it is fine and will run till it dies, BUT if I were to close it and put it to sleep it will not turn back on. I would have to plug it back in and turn it on then I can unplug it and it will be fine till it falls back asleep.
Once I do turn it back on, a pop up says that I need to re adjust the clock and another trying to search for the internet, even if I was already connected with is 5 min ago. Even apps like tweetdeck and facbook would reset and I would have to enter all my information again, where as before it would just remain there.
I have NO idea why it is like this and I am not really familiar with a Mac and its OS but any information would be greatly appreciate!
Thanks!
Yoshi

Bring it to an Apple store or AASP. You are under warranty.

My iPhone is stuck in recovery and wont restore error (9) what do I do?

My iPhone is stuck in recovery mode. I have updated my Mac I tried to update iTunes but thats when i got the can not restore unknown error (9). I tried another cord I tried to update iTunes again but nothing kept getitng error code. I Then deleted iTunes and was going to try and reinstall it but apparently there are major issues with it and you can not download it right now. So basically I am stuck with a phone a can not use. Is anyone else having this problem?

Well, as a start, Recboot hosed the network database on your computer, which could be the problem. Especially if you had used it at some time in the past. Look in /etc/hosts, and if you see any lines containing "gs.apple.com" delete those lines.
From your profile you are also using a version of OS X that is not compatible with iTunes 10, which is required to update iPhones. You need OS X Leopard 10.5.8 as a minimum.
See: http://support.apple.com/kb/TS3694#error9 for other tips. You could have a bad or dirty connector on the iPhone also. Try cleaning it with a soft, dry toothbrush.

Iphone wont turn on unless plugged in

I went to get a ZAGG invisibleSHIELD done on my iphone, after the installation, my iphone keeps rebooting to the apple logo without going into the menu screen, and the power button (top button) doesn't work.
However, everything works perfectly when it is plugged into a power source (both the wall plug and to a computer). It turns on fine, with as if nothing is wrong. I don't even need the itune to boot it.
Now if unplugged it works fine until the screen turns off automatically. If I were to turn on the phone within seconds then its fine, but if left "off" then the phone refuses to turn back on, until it is plugged into a power source again.
(sometimes it goes back to the apple logo, and does the whole boot up/turn off thing.)
I assumed that some liquid seeped into the phone since nothing was installed, or "changed", but what i don't understand was why the phone works perfectly if plugged in.
I left the phone to "dry" for 24hrs, and now the top power button works, and it was working perfectly fine all afternoon, till an hr ago where it refuses to turn back on again.
So is it some "bug" in the system or is it really that some moisture seeped into the phone?

well the headphone moisture sensor is white. i can't locate the docking port one however i dont see anything pink or red.
well the update on the phone is that after the 3rd day, the phone works perfectly fine now, however the power button is only 1/2 as sensitive as before. it needs to be pressed down hard to turn on, while sometimes the button remains non responsive.
So im guessing that some liquid was dripped into the power button causing the phone to malfunction because it was receiving random power on/off signals.

Ipad wont turn on unless i put it in dfu mode, and then it still turns off within a few minutes, ipad wont turn on unless i put it in dfu mode, and then it still turns off within a few minutes

my ipad 2 turns off by its self, it works perfectly fine otherwise, the condition is very good and it has never been dropped or anything. it turns off by itself and then i have to put it in dfu mode and recover it to turn it back on otherwise nothing else works. once i put it in dfu mode, the ipad turns on once fully recoved and restored to orginal settings but a few minutes later the process repeats, and turns off again. any helpp?

If your iPad is jailbroken, we can't help you.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem (very likely), make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem. Likely a bad battery.

Why does my iPhone 4 turn off when plugged in?

My iPhone wont turn on unless plugged in, so I plug it in and it turns on..it says it's Wednesday Dec. 31 , 4:01 and thats wrong. It also says the battery life is at a 100% but I know that isn't right as well. It shuts off and then powers on again and repeats the same thing. I tried plugging it in to my Mac and the apple logo comes up and then goes away and that repeats over and over if plugged in.

Hello StephanieeLovezYou,
Thank you for the details of the issue you are experiencing with your iPhone. I would be concerned too if my iPhone was only turning on when connected to power. I found an article with steps you can take when you encounter an issue like this. I recommend following the steps below:
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.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
My issue is still not resolved. What do I do next?
Contact Apple Support.
