Other users have similar problems with either red or pink flashes. It is important to release the keys as soon as you hear the startup sound for the second time.

When i plug in my ipod touch (8gb, 3rd generation) it doesn't turn on and the apple logo flashes on and off. how can i stop it and turn on my ipod??????

when i plug in my ipod touch (8gb, 3rd generation) it doesn't turn on and the apple logo flashes on and off. before this it wouldn't turn on unless it was plugged in.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- 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.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Classic: will not recharge; apple logo flashes every few seconds then fades away; have tried the 'reboot' advice i.e. move hold switch on and off, hold menu and center button, no success. have tried this many times and kept connected for several hours.

I have tried this many times and kept the ipod connected for several hours. And I have tried two different cords, one connected to the desktop computer, one connected to electrical outlet.

Try leaving it on a charger? Might be low battery life.
Try a hard reset holding the Home button and sleep/wake button ( The circle button, and button on top)

How do i fix my issue: Apple Logo flashes on and off after iphone battery died during IOS update?

I've tried the methods I've seen on youtube and other iphone tech help sites but I am still having the same problem. Today while updating to IOS 7 my iphone 4 battery died and I didnt have a charger, now that I am home an I put in on the charger I notice the apple logo just flashes on and off. I've tried to restores using the DFU mode with the home and power button but that only seem to stop the logo from flashing and even then the iphone still isnt recognised by the pc to restore, Is there any other way i can go about fixing this problem!!!!

You can try the steps recommended in the User Guide. If they don't work bring your phone into Apple for evaluation.

My 16 GB iPhone 5 is stuck on a black screen. A white screen with the apple logo flashes occasionally. iTunes won't recognize the phone, and hard reboot failed. Can anyone help?

I just bought a gently used 16 GB iPhone 5. I set the phone up earlier today with no issues at all, installing backup data from my iPhone 4, syncing the new phone to my iCould, setting up my new SIM card, etc.
The phone was working fine (I was able to send and receive texts, use WiFi, manage apps, etc.) for the first hour or so. Then, without warning, it shut down. The screen is solid black, but every now and then it flashes white with the black apple logo.
I tried multiple hard reboots — all failed.
iTunes (on my MacBook Air, running Yosemite) is now unable to recognize the device, although it recognized it without issue earlier today.
I live overseas, so going to an Apple store is a bit inconvenient. If I can trouble shoot this at home (and in English), it would be really helpful.
Thank you in advance if you have any helpful tips or suggestions!
Best,

Gregseymour-
DO NOT STICK A PAPER CLIP IN THE HOLE!
There are two holes. One is a small one that has a microphone behind it. A paper clip would probably ruin the microphone. The other is a 1/8 inch hole where you plug in a headset. A paper clip might short-circuit something.
First connect the iPad to its wall charger for at least half an hour to be sure it has enough juice to get started.
Then if the iPad does not wake up when either the Home or Sleep button is pressed, press and hold the Sleep button for several seconds and see if the Apple logo appears. If it does, then your iPad has been turned off instead of merely being put to sleep.
Beyond that, look for an iPad repair center. The Apple Authorized Repair Centers may be more expensive. If you want to try them, look at <Apple Authorized Repair Centers>. There may be one in your city.

Ipod nano 6th generation apple logo flashing

I have an ipod nano 6th generation that when connected to the computer USB it flashes the apple logo. When not connected, it does not turn on at all. I have tried all the reset tricks with no impact. Also, my iTunes does not even recognise it as being connected to the computer. Any ideas I haven't explored yet?

Hi magostin,
Welcome to the Apple Support Communities!
In situations where your iPod nano is not recognized in iTunes, I would suggest the troubleshooting steps in the attached article. Please use the troubleshooting for Windows or Mac in the article depending on what type of computer you are connecting to.

Problem with iphone5 not switching on apple logo flashing

iphone5 wont switch on & apple logo just flashes. Cannot restore either. ?

Zemoj, if you have an Apple Retail Store, they can test your battery. It sounds like you battery is at the end of its life.
Mikewood25. Check for security software blocking iTunes from communicating with your iPhone. Sometimes you have to remove the security software completely—shutting it off doesn't do the job.

Has anyone seen a Blue Apple logo on the grey startup screen?

This morning I received a pop-up message on our Mac Mini that said we had to restart it by holding down the power button. The machine seemed locked, the mouse was gone, Command, Option, Esc would not work, etc. Not having any other option, I held down the power button and shut it down. After it was completely shut down, I pressed the power button again to restart it and that is when the normal grey screen appeared but the Apple logo in the middle of the screen was blue instead of the normal grey. Has anyone else seen this scenario? I'm concerned that it is an April Fools virus but have no way to diagnose it. Some details about our machine below:
Mid-2011 Mac Mini
OSX 10.7.5
Sophos Anti Virus

Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

IPhone 5 apple logo flashing when on charge.

My iPhone 5 randomly turned off last night and I was unable to turn it on. I then plugged it into a charger and the apple logo appeared and then went again. This flashing has been happening continuously - black screen for 5 seconds, apple logo for 10 seconds.
I found that if I held the power button 3 seconds, then also held the home button at the same time for ten seconds and the released the power button and held just the home button for another 10 seconds, the flashing stops and the screen goes black.
However, the flashing only occurrs when my device is plugged in to charge, if it isn't it is just a black screen, no matter what buttons I press.
I looked on the internet and they all say hold the power button and home button for 6/10/12/60 seconds, which does not help. Others say I have to restore it, but I havent backed up my phone in a while and all my important photos are on there that I do not want to lose. I then downloaded the software EaseUS MobiSaver which advertises that you can back up your phone even if it doesn't turn on. This also failed to work and the software cannot pick up that my iPhone is plugged in.
Also iTunes only picks up my device when its in restore mode but says I have to restore it before I can do anything further on iTunes.
Is there another way to fix it without restoring?
Thank you and sorry for rambling.

Hi there socko0603,
At this point, the next troubleshooting step is to restore the device in iTunes, there is no way out of Recovery Mode without restoring. Take a look at the article below for more information.

Apple Logo Flashing?!?!?

I just got this IPOD MINI the battery was very low, so I tried to charge it with the USB cable.
When i connected it, the apple logo appeared on the screen and just began flashing slowly. The ipod doesnt show in iTunes and i've been charging it for a while now over 2 hours. The flashing of the apple logo is getting faster now.
Does anyone know why this is happening?!?
btw, i downloaded the ipod updater, and it does not work!
plz help me thx!

Bring your ipods to an Apple service center. I tried EVERYTHING in the discussion boards and nothing worked. The technician recommended my mini for replacement within three weeks. I'm still waiting and hoping it will solve the problem.
The thing is, I recently found a post orpheusinhades, "Same problem as loads of other people HELP!" #8, 09:46am Sep 16, 2005 CDT
where a user said that even his replacement ipod isn't working properly.

Apple logo flashes with battery and exclamation point alternately

i have an ipod nano, everything was going fine until the battery ran out, when I plugged it back in the thing flashes the apple logo alternately with a battery and exclamation point. If the battery is completely dead then fine I will replace it but is that what it really is?

Have you tried connecting the iPod to different USB ports and/or another computer?
You can also take a look at this website, which may help figure out what's wrong with your iPod.

Finally, if your iPod is less than a year old, you can send it to Apple for replacement.
