Apple logo screen changing colours in a loop

My phone randomly went in a loop of the apple logo (with the white background) changing colours (sometimes red, blue, grey) and I can't restore it or connect it to my computer!
Please help!

Hi gzhu22,
To troubleshoot this issue where your iPhone will not boot past the Apple logo and is showing different colored screens, please follow the directions below.
If your device gets stuck during startup
When starting up, you might see the Apple logo or a red or blue screen for a long time, or your device might restart again. Try these steps:
Make sure that you have iTunes 12 or later on your computer.
Put your device in recovery mode.
When you get the option to restore or update, select Update. This will reinstall iOS without erasing your data.

If you still need help after trying the steps above, contact Apple Support.
If your iPhone, iPad, or iPod touch doesn't respond or doesn't turn on - Apple Support
Take care,
Alex H.

Frozen Ipod/ Ipod keeps rebooting at black apple logo screen (on loop)

Frozen Ipod/ Ipod keeps rebooting at black apple logo screen (on loop)
-I've already replaced my old 60 GB Ipod in exchange for an 80GB, I bring it home, sync it up with Itunes v7.02 and everything works fine for a while. Not even 24 hours later I go down into my artist/song directory to play a song, and it freezes again. I do the menu center key soft reboot a few times to bypass it and it works for awhile. I've tried looking for current updates for software on it, Restoring it, Resyncing and now It gets to the point everytime I unplug the ipod from charging I get back to the menu and try to play a song or video and it does nothing, it freezes everytime.
There has to be an explanation as to why my first one did it and why my new 80GB is doing it.
I've already ran a diagnosis on all the files in the ipod all of them come back clean.
Help me out.
If you know how to resolve this issue reply and/or email me

My ipod is having a similar problem. The black apple logo has been the only thing I see on my ipod. I went a step farther and held the select and play/pause button to get it into disk mode. Once I am here I cannot proceed. I do not have computer that I hook it up to and have transferred the desired songs from an ex-girlfriends computer which I do not have access. What can I do once I have it in disk mode if I do not have a computer available?

Single-User Mode Copying Files/System Does not Boot Past Apple Logo Screen

I have a Macbook 2.0GHZ, 2GB RAM, that recently tried to download a secuirty and keynot update. Following the download the system will no longer boot past the Apple Logo Screen with the spinning wheel. I do not have access to a OS disk yet or to a firewire cable either. I've have seen posts from others that describe how to use traget disk mode to reinstall the secuirty update manually and then they can boot their computer. Safe mode will not work. I did boot into single-user mode and run the disk utility there and it says my HD is OK. Since I do not have a firewire or an OS Disk, I am wondering if there is a way to copy those files i need to a USB pen stick then install them onto the computer via single-user mode, considering this is the only way I can boot and manipulate the machine at this time. If this is not possible please let me know so I can find a way to scrounge up a firewire cable or disk. Thank you in advance for any assistance.

Thanks to Limnos and BDAqua I know you guys have helped others with these kind of problems from the other posts I read. I just want to list what I did exactly in case anyone wants to try to do this with a usb drive or does not have access to a boot disk or firewire cable.
1: Install security update on a pen drive
2: Boot in single user mode, CMD-S on startup
3: /sbin/mount -uw /
4: mkdir /Volumes/usb (usb can be any name, name of usb drive or anything you want)
5: ls /dev (you need to get the drive listing for the usb drive to mount it appropriately, it should be disk#s# but this is close to what the HD and Cd drives are listed as so you may need to list once before you put the usb stick in and once ater. I had issues inserting the usb drive in single-user mode and it would freeze up the root drive)
6: /sbin/mount_msdos /dev/disk1s1 /Volumes/usb (this mounts the usb drive, i had to use msdos because of how my usb drive was formatted, you may need to check your usb drive format, hfs is the apple format for usb drives but it did not work for me)
7: cp /Volumes/usb/SecUpd2009-001Intel.dmg (this copies the files from the usb drive to the root drivel, at this point you no longer need the usb drive)
8: hdiutil mount /SecUpd2009-001Intel.dmg (this mounts the disk image)
9: cd /Volumes/"Security Update 2009-001" (after i mounted the image this is how it appeared in the Volumes directory, you might need to do ls /Volumes to get the name, the quotes are important to get the whole file directory changed)
10: installer -pkg SecUpd2009-001Intel.pkg -target / (this installs the acutal update, i used the SecUpd2009-001Intel.pkg and it worked though I think you might be able to use "Security Update 2009-001" with quotes as well.)
11: reboot
i hope this helps anyone looking to do this. Thanks again to those who helpes and all the other posts that had information that helped me identify and then fix my issue! I still love my mac.

My 2011 IMac will not boot up past the White apple logo screen with the whirly circle

My 2011 IMac will not boot up past the White apple logo screen with the whirly circle. I have tried various commands but to no avail. does anybody have any advice?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Imac 5k stuck on apple logo screen after latest update

Hi - i have a magazine deadline and a major issue:
i've been having loads of kernel panics (see thread here Brand new imac 5k kernel panic) and having seen there was a new update figured it would be worth installing it to see if it fixed them as nothing so far suggested by apple support has helped. Once it had downloaded the update the OS said it needed to reboot to finish installation. It got half way through the loading bar on the apple logo screen and got stuck. I left it an hour, came back still nothing. Left it another hour and it was still just stuck half way. I rebooted into diagnostics and ran that and it said everything was fine but further reboots just get as far as halfway through the bar. I'm now stuck as the computer was only a month or so old and i hadn't yet set up back up on it. I was still in the process of getting everything configured and over from my old machine. Problem is I have a bunch of photos that were transferred on to it that i shot 2 weeks ago and I need them for a magazine deadline tomorrow and apple support options could only call me back on Thursday - if anyone can suggest anything i will be VERY grateful. I've already tried SMC and PRAM resets.

I did that, a fresh OS install and it worked for about 4 hours then i got a kernel panic

PowerPC Mac Mini gets stuck at grey apple logo screen, wont start

I have a bit of a problem and would appreciate some help, im not especially good at this stuff.
My Powerpc Mac Mini froze up recently, having left it on for a few days without shutting down/resetting. I impatiently turned it off with the power button at the back. When I turned it on again, it only got as far as the grey apple logo screen, it now refuses to go past this screen despite numerous power resets, and unplugging at the power.
I have reset the PMU and the PRAM as suggested by the troubleshooting, to no avail - the PRAM did work as it changed the resolution of the apple logo, but still got stuck at the grey startup screen. Its out of warranty so I have to pay for technical support. Can anyone help?

If you have the original install disk that came with your mini, the first thing to do is to insert that, and then boot the system holding the C key down. This should force it to boot from the install disk rather than the internal drive. The reason you want to do this is two-fold: firstly that if it boots OK that way, it shows the basic hardware is OK, and secondly, it's possible that the hard drive has developed errors (likely directory damage) and the tool to check for that and attempt to resolve it is on the install disk.
Once you've got the system booted to the install disk, exit the installer and run the Disk Utility application. That should display the internal drive (and the install disk) on the left. Select the internal drive and then click 'Repair Disk'. If no errors are found, the drive is fine and the problem lies elsewhere. If errors are reported and the disk is fixed, then you should be able to reboot normally afterwards. If errors are found and Disk Utility reports 'error on exit' not having fixed them, then run it again just to be sure, but otherwise it means the drive is damaged sufficiently that Disk Utility can't fix it. A third-party application such as Alsoft's DiskWarrior will then be needed if you want to try and fix the drive and recover data, or you can simply elect to do an erase and install, meaning the drive will be reformatted and a new copy of MacOS installed. Do not do this if you have data you need to get off the drive!!

5G iPod stuck at apple logo screen - will not finish booting, just restarts

I just got off the phone with Apple.
Has anyone had this occur.
I had to reset my iPod a few hours ago, it never made it past the brighter apple logo. It looks like it's about to turn back on and then decides "let's try that again" and clicks back to the fainter logo screen. It's been looping like that for over two hours now. I need to let it drain now, but the apple tech didn't sound too hopeful.
just wondering if anyone else has had an iPod die this way...

IPhone 4 stuck in Apple logo screen

I have an iPhone 4, that I had to replace the LCD, power switch - proximity sensor cable, and home button on.
After I had made the repairs (after making sure everything was reassembled correctly) I then proceeded to turn the device on.
Now it will only display the Apple logo at startup.
When I turn the phone off (via the Home + Sleep/wake method) it will sometimes revert back to the Apple logo screen.
I have reset the phone (gone through recovery mode) at least 5 times to correct the issue, yet it still is not working correctly.
The only software change that had been made to it, was that I had updated it to the most recent version of iOS. And that was approx. 2 weeks before the issues with the phone.
Is there another solution to fixing this phone, or is it basically done?
(If I can, I really need to get this phone fixed (if at all possible).
Thank-you.

Thank-you for the reply.
I have checked the charging port. It checked out to be good.
I then checked the following flex connectors:
Digitizer - it checked out ok
LCD - While it did check out ok. I wonder if it might have a defect in it. (because it does flicker)..
Earpiece - checked out ok.
Front Camera - checked out ok.
Power switch / proximity sensor cable.- Bad...
During my testing of the phone, any time I would turn the power on to the phone. If I unplugged the connector for the power switch. The iOS would continue to load, but if I left it plugged in. Then it would stay on the Apple logo.
I will reply to this thread after I receive the replacement part, and I have had a chance to check it out (to make sure that takes care of the problem.

Hello samueljacob,
Thanks for using Apple Support Communities.
If your iPad isn't booting up completely and is stuck on the Apple logo, then I'd like you to please start with resetting the iPad.
Restart or reset your iPhone, iPad, or iPod touch - Apple Support
If the issue persists, then please follow the steps outlined below.
If your device gets stuck during startup
When starting up, you might see the Apple logo or a red or blue screen for a long time, or your device might restart again. Try these steps:
Make sure that you have iTunes 12 or later on your computer.
Put your device in recovery mode.
When you get the option to restore or update, select Update. This will reinstall iOS without erasing your data.
If your iPhone, iPad, or iPod touch doesn't respond or doesn't turn on - Apple Support
Take care,

My iPod is stuck on the black apple logo screen

I was using a texting app and all of a sudden, my iPod went to the apple logo screen and froze. The apple on the screen is messed up, it doestn't look right, like there was a glitch. I tried restarting it by holding the home button and the button on the top. It turns off, but when it comes back on, the apple is still messed up. I tried this multiple times, a few times there were thin pink, and sometimes blue, lines all across the screen. I also tried hooking it up to my computer, but it doesnt show up on my itunes, and the screen doesnt change. My iPod was charged and was working like normal before this happened. What should I do? Is this fixable? Is it the app's fault that this happened? Any help would be greatly appreciated.
P.S. My warrenty has run out

Typically, this happens when a Touch is "jailbroken" - but I suspect that isn't the case, here.
The you've saved all of your data on iTunes, correct? Then, you next step will be to reset the Touch (pressing the start and power buttons at same time for ten seconds or so), until your Touch resets. It will recompile your library, and can take about an hour. Make sure your Touch is fully charged, of course.
When you're up and running, you might want to nuke that texting app, too.

Frozen on Apple logo screen

I reset my iPod Touch by pressing both the Home and Sleep/Wake buttons. The Apple logo appeared as expected, but the iPod stayed frozen on this screen. Every so often the screen briefly "flashes" (like it's about to change to the welcome screen) but then it returns to the Apple screen.
I tried letting the iPod run out of power until the low battery icon appeared. When I connect it to either a Mac or a power supply, and once it charges up enough, the Apple logo appears again and it is frozen.
The iPod does not show up in iTunes. It is a 32Gb 2nd gen iPod Touch running 3.12 (I think) and has LOTS of applications.
Any help greatly appreciated!

Thank you! The recovery procedure you linked to seems to be working, though it was slightly different for me than on the Apple site.
Specifically, when I held the Home and Sleep/Wake buttons, my iPod would eventually return to the Apple logo screen, rather than turning off. I found that if I held both buttons and waited for the screen to briefly go black, I could release the Sleep Wake button, and connect the iPod to my Mac, while continuing to hold the Home button.
It took a few tries, but eventually I got the iTunes dialog box (about recovery mode) and was then able to restore the iPod to its factory settings.
I am in now the midst of restoring my iPod to its most recent backup, and I'm hopeful that you've solved my problem. Many thanks!!

See if you missed anything here:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

DESPERATE PLEASE HELP So my mother got herself an iPod touch 5g for Christmas and barely asked me to set it up last night, (BRAND NEW NOT OPENED YET).. I set it up not plugged into iTunes (directly on iPod). I was setting up a new iTunes account for her (got passed Wi-fi set up and location services) and as I was doing that, it mysteriously froze somehow. So I held the home button and power button down simultaneously, which I thought would restart the iPod/shut it down.. so it did, and it was on the apple logo screen for a LONG TIME.. and when I checked after a long time, it was black. I tried to turn it on, charge, and plug it into itunes (iMac computer) and it won't turn on!!!!! PLEASE HELP
