Infinite Restart Loop

My friend's iPad 4 has a problem. It keeps constantly restarting! The Apple logo comes and the screen turns black. Then, it repeats doing that!
If some one has advice on what to do, please share it with me!

Hello, zujojo.  
Thank you for visiting Apple Support Communities.  
Here is an article that I would recommend going through when experiencing this issue.

  • Accidentally deleted /var/tmp directory and I'm now stuck in an infinite restart loop

    So guys, I was poking around and I accidentally deleted that file. I am now stuck in a restart loop that sometimes ends with a white kernel stop sign in front of  a black screen. When that happens, I am forced to restart my computer again.
    Every time I restart, the loading bar is about 1/5 of the way there when a series of messages show up on the top left of the screen. I took some pictures of the message, and I have inserted it below.
    Again, the directory is /var/tmp, and I am not sure if it was /private or not. I'm sorry.
    The kind person who fixes this issue will get my undying respect.
    Again, thank you guys very much.
    I own a 2012 15 inch MBP, if that helps.

    In addition to what greg sahli suggests, also issue the commands:
    chmod 1777 /var/tmp
    chown root:wheel /var/tmp
    My commands and greg sahli's suggestions ASSUME that you did not delete other things essential for the normal operation of Mac OS X.
    Otherwise you will have to follow mende1's advice and reinstall Mac OS X.

  • 10.4.8 causes an infinite restart loop?

    Just ran the update and now my macbook is stuck in a perpetual loop. It tells me I need to restart my computer, i do, and it comes back the same window telling me to restart the computer. Endlessly.

    The MacBook is rather a catch-22 since one of the best utilities for fixing the directory is not yet Universal, Disk Warrior. I would get Prosoft Data Rescue on CD, and attempt to see if you can boot off the CD and restore data to an external hard drive that is Firewire of equivalent size. Once that is done, fix the directory and repair permissions with my FAQ:
    http://www.macmaps.com/directoryfaq.html
    If you are able to repair it with that, great, if not and you are able to boot the recovered backup, restore your backup after erasing the original. If you can't boot from the recovered backup, I'd take the machine to a data recovery facility.
    Always remember to backup your data first so issues like this don't happen as my FAQ says:
    http://www.macmaps.com/backup.html
    It is not a question of if hard drive will fail, but when. We don't know that you have had a failure of the drive, or the directory, or some other hardware. But unless we can be sure the directory is good, we can't isolate the potential for other hardware to be good or bad, except through the hardware test that came with your MacBook restore DVD/CD:
    http://docs.info.apple.com/article.html?artnum=303605
    If nothing shows wrong there, it may still be the RAM, but we have to isolate the possibility of third party peripherals and the directory.

  • Ipod nano ist gen- infinite restart loop

    So I've had my nano for about 5 years now. I also have a touch, but I use my nano when i go to the gym and whatnot. Anyways, just a few days ago I turned my ipod nano on and the screen said to connect it to itunes and restore, So I did and itunes told me to restore, and i did. When it said the restore was finished, i looked at my ipod screen, it had a loading bar, and then the message came up again.
    Solutions I have tried:
    -disk mode
    -rebooting
    -restoring
    -changing disk location
    -reinstalling itunes
    -checkdisk/defragment (it's worked for me before)
    -formatting
    Help would be greatly appreciated.

    That used to happen to me. Try too find another way to charge your ipod after about 10 minutes, plug it back into your computer. If this doesn't work then youi must have some other problem.

  • Windows 10 Upgrade infinite boot loop after reset

    I did a Windows 10 upgrade on an old computer with these specs:-Windows 7 Pro- 64 bit-Dell Optiplex 755-4 GB RAM-Intel Core2 Duo processor Everything ran fine after the upgrade. However I wanted to do a clean install. So I did so and chose the option to not keep any files or programs. It went through the process and was stalled at 99% for some time. I let it run over night. I came back and looked at it about 16 hours later and the 99% was gone, but the "hourglass" was still going. I pressed Escape and then CTRL+ALT+Delete to try to get it to respond. Now it is stuck in an infinite boot loop. It will reboot and then after several minutes it brings up an error message of "Your PC ran into a problem and needs to restart...- Inaccessible boot device." Then it restarts and the loop starts over.I've tried booting into safe mode using F8, but...

  • Iphone stuck in infinite setup loop

    My iphone is stuck in an infinite setup loop. Have reset phone a lot of times and it lets me set up all info. I get home screen for less than 2 seconds and the set up screen pops back up. Randomly the voice over will come on and the tripple tap to enter from kep pad/board comes on or goes off. HELP!

    Hello DebiSuzi,
    Not being able to use your device can certainly be frustrating. From what I can gather, it sounds like you're having issues restarting your device. After reviewing your post, I have located an article that can help in this situation. You may want to consider restoring your device to factory settings. After this is complete, I would recommend restoring your data from any potential backups you may have:
    If you can't update or restore your iPhone, iPad, or iPod touch
    Use recovery mode
    You might need to use recovery mode to restore your device in these cases:
    iTunes doesn't recognize your device or says it's in recovery mode.
    You see the Apple logo onscreen for several minutes with no progress bar.
    You see the Connect to iTunes screen.
    Learn what to do if you see the progress bar onscreen for several minutes.
    To put your device into recovery mode, follow these steps:
    Turn off your device and leave it off.
    Plug in your device's USB cable to a computer with iTunes. 
    Hold down the Home button on your device as you connect the USB cable. Keep holding down the Home button until you see the Connect to iTunes screen.
    When you see this screen, release the Home button. If you don't see this screen, try steps 1 through 3 again. 
    When your device is connected, iTunes will open. You'll see a message saying that iTunes has detected an iPhone, iPad, or iPod touch in recovery mode.
    Use iTunes to restore your device. Restoring in recovery mode will erase your device. If you previously synced with iTunes or iCloud, you might be able to restore from your backup.
    Get more help
    Learn what to do if you don't see your device in iTunes for OS X, or in iTunes for Windows.
    If you put your device into recovery mode by mistake, restart it. Or you can wait 15 minutes and your device will exit recovery mode by itself.
    Thank you for contributing to Apple Support Communities.

  • Java Console Stuck in Uninstall Restart Loop

    Hi! So, recently, I've noticed that I've been having issues that seem to be Java based, so I've decided to do a full uninstall/reinstall of Java. I uninstalled all Java based applications via control panel, assuming it'd be uninstalled from Firefox as well, allowing me to just reinstall.
    However, I have three versions of the Java Console showing up on my Add-ons page, and all three are stuck in an infinite "The add-on will be uninstalled when Firefox is restarted" loop. No matter how many times I shut down/restart Firefox (even as an administrator), it won't uninstall.
    I also can't manually uninstall because the extension folder is no longer in my Profile folder.

    BBSAK might be ale to nuke it so you can.
    Manual device OS upgrade instructions:
    1. First locate your carrier and the OS file you wish to use.

    5. This step is not needed unless there is an issue on next steps. Use BBSAK from BBSAK.org and wipe the device (after doing a complete backup) then after you get the error 507 (no OS installed) then proceed to step 6
    6. remove internet connection to PC and reboot PC.
    7. Plug in BlackBerry and double click on "Loader.exe." It's located in the same place as the above vendor.xml file was in.

  • How to out from infinite while loop in sub VI

    Dear Sir,
    how to out from infinite while loop in sub VI from main VI
    attached photo for solution but I can't understand it and i can't find the function in photo 
    please help
    Attachments:
    stop_subVI_frm_main.JPG ‏36 KB

    Asking how to get out of an infinite loop is like asking how to find the end of a circle. I'm not trying to be sarcastic but by definition, if there is a way out of the loop, then it is not infinite. I think what you are asking is how to avoid creating an infinite loop. Is there something about the suggestions you have been given that you do not like? My favorite suggestion is the notifier but maybe you just need an example. Turn on context help and read about the notifier functions in the code below.
    This is your top level VI
    And this is your subVI
    If this seems too complex then a global variable will work too. But what seems simpler can cause much more complex bugs. You can code fast and spend lots of time debugging or you can code slow and spend less time debugging. Personally I perfer writing productive code than looking for bugs any time.

  • Stuck in Restart Loop after Software Update

    I recently ran the update to 10.5.3 a few days ago, and thankfully, it's been working great... until today, when I installed two seemingly innocuous updates via Software Update: one for the latest version of Quicktime and another for Apple Brother Print Drivers 1.1. After restarting, everything fell apart. Several of my start-up apps unexpectedly quit after login, and other apps either failed to launch when I tried opening them, or they simply got stuck in an endless loop of bouncing in the dock. I couldn't even force-quit them because they weren't responding at all. Thinking this strange behavior to be symptoms of some permissions issue, I popped in the Leopard installation CD and ran a permissions repair. It fixed several cryptic problems, one for something to do with Java and another for the cups folder, which I assume has some relation to the printer driver update. I then tried selecting my start-up disk and restarting, but the problem only got worse. Now my iMac is stuck in a restart loop. I tried booting in safe mode, but that hasn't worked. If worse comes to worst, I'll have to revert to a Time Machine backup, or else run an Archive & Install, but I'm trying to avoid that. Any suggestions? I'm also curious to know if these two updates had any relevance to these problems, and if so, what the cause may be. I'm thinking the printer driver is to blame, but then again that's only a stab in the dark. Any help would be appreciated. Thanks!

    Thanks for the suggestions. I tried a Safe Boot again but unfortunately that didn't work, so I had to go ahead and do an Archive & Install. Now everything is up and running; however, I'm going to stay away from that print driver until I figure out exactly what went wrong. I did a little research and saw it listed on MacUpdate.com, where it was posted along with an interesting note: apparently, the update can only be applied if there is already a Brother print driver installed (in this case there was), and in addition to that, the printer must either be connected (and I assume on for the computer to know it's connected in the first place) or have an active print queue for the update to even be listed in Software Update. Strangely enough, neither of these conditions held true when I saw it in Software Update... so I think that might have been the cause, but I can't be sure. I was wondering if anyone else has installed this update successfully, and if so, what they did?
    Thanks again for the suggestions.

  • Macbook Pro stuck in restart loop with fresh install

    Hello!
    I have a Macbook Pro (Mid 2009) that I have been running Snow Leopard on up until now. I had been meaning to upgrade to Mavericks for a while, but had just never gotten around to it. Over the last month or so, my Macbook has been running really slow, hanging on the spinning beachball every few minutes for a few seconds (sometimes up to a minute or so). So I figured a clean start might be the best way to go, and while I'm at it, I might as well upgrade to Mavericks.
    I backed up all my data, and then I created a Mountain Lion bootable usb (I had trouble making a Mavericks bootable usb from Snow Leopard, and since I had bought Mountain Lion for my desktop, I just decided to do a fresh install of that, and then upgrade to Mavericks). I had no problem booting to the usb, erased my hard drive and did a fresh install of Mountain Lion. However, after the install on the usb, my mac restarted and got stuck in a restart loop. It will chime, show the apple logo and spinning gears for a few seconds, then the gears stop spinning, and then the mac immediately restarts (this time displaying a message saying the mac has recovered from a shutdown in a number of languages), and the same thing happens again.
    I was able to boot into the recovery partition, checked the permissions, found some that needed to be fixed, ran the repair permissions, verified the disk and was told the disk appears okay. Tried to then restart and same thing.
    I have reset SMC, NVRAM, and none of these change anything. I booted in single user mode and ran fsck -fy, and recieved a message saying modifications were made, rebooted, same thing.
    I have booted in verbose mode and the system restarts at the same point every time, right after displaying a message that says
    SMC::smcReadKeyAction Error: (and then something with "BEMB", it goes by really fast so its hard to read exactly)
    I have managed to boot into safe mode, but this has not made a difference. On one of my boots into safe mode, I went ahead and made a Mavericks bootable usb, and restarted the process: wiped the drive, installed mavericks, but I am in the exact same situation. I can still boot into safe mode.
    I have seen some other issues that people have posted, but most involve the system freezing after the apple screen (not restarting) or do not involve freshly formatted HDs.
    I'm just tying to find out if this is a hard drive issue, or if my mac itself needs to be retired. It has had a pretty long life (being 5 years old), and one of the RAM bays doesn't work (it is only running 4GB of ram, not sure if that can cause a problem with the boot cycle).
    Sorry if thats a lot of information, I've been trouble shooting this for a few days. But thanks for any help you can offer!
    A strange note:
    -when booting from the mavericks usb, I got stuck in the restart loop a couple of times. I managed to get past this by clicking the mousepad a few times right after the gears finished spinning. The mouse became visible, the apple screen shifted color a bit (went from a bluish gray tint to an orangish gray tint), the mouse became visible, and I got to the reinstall menu as normal. As far as I can tell the clicking may have been coincidental, but it was the only time I was able to boot the usb, and I wasn't going to risk restarting to test that, and then not be able to boot again.

    Hey, thank you for your reply! I didn't have everything backed up, but I have a lot of my important stuff saved, though, so that's somewhat of a relief..
    As far as my hard drive is concerned, would I have to send it in somewhere to get it fixed or would I just have to get a brand new one? If so, how much? Sorry if I seem a bit amateur, but this computer is my first personal computer, and I'm really lost without it!

  • Win 8.1 goes into restart loop

    I have an hp touchsmart tm2 2100 notebook. It originally came with win 7. Now I have installed win 8.1 but it does not give a display on multimedia ( i am a teacher and have to do a lot on multimedia). when I upgrade the driver, it goes into a restart loop and continues for a while. At the end, it gives a restore or advance repair options. I go into the safe mode and uninstall the intel graphic driver. It comes back to its originla position.
    Please any suggestions on how to sort this out.

  • Macbook Restart Loop when trying to install OS X Yosemite

    I've tried to update my 10.8.5 to Both Mavericks and Yosemite but in both cases it gets locked in a restart loop. This happens when I press install and it say that it will now restart the computer.  My Macbook pro is from late 2008. is that the problem?
    I pressed Command+R and restarted the macbook and it went back ro 10.8.5 again.
    So what can I do to install the OS X Yosemite. Any body know?

    Hold on.
    7,1 is a mid 2007 model (20 or 24")
    It can run Yosemite, make sure that you have at least 4GB of Ram.

  • PRS-T1 stuck in infinite reboot loop after failed firmware update

    Hi,
    I tried to update the firmware, but failed when updating to version 1.0.07.05070. Tried to 2 times. The first time it failed I simply tried again. The second time, it took a lot longer to reach the failed to update message, but it did cause the ereader to reboot.
    Now, it's stuck in an infinite reboot loop on the "Opening book" page. The progress bar on that page stays completely empty, lasts for about 30 seconds, and reboots again. This will go one until the battery is dead or indefinitely if plugged in. 
    I have tried pressing the Home + Menu buttons, but they seem to have no effect.
    Please advise if there is anything I can try to revive it?
    Thanks in advanced.
    David
    Solved!
    Go to Solution.

    Kiroken,
    Here is what I have observed:
    - After a hard boot (reset + power button during 3+ seconds), if I don't do anything, it will reboot every ~30seconds.
    - If I press and hold the Home and Menu buttons, no effect. The same as if I didn't press anything.
    - If I press the Forward + Back buttons (2 & 4), it does not reboot after 30 seconds. Instead, the orange light on the power button blink every ~2-3 seconds.
    - Any other key combinations that I have tried have no effect.
    I have tried with and without several rescue sdcard. No difference. No improvement. In every case, the computer never sees the reader. If plugged into the power outlet, it seems like the battery charges alright. It does not appear to charge if plugged into USB port.
    That's all I know. If I can't fix it, I might be forced to turn it into a coaster or maybe a cutting board for the kitchen.
