Q: iPad 2 keeps crashing rebooting after ios 8 update

Try some basic troubleshooting:

(A) Try reset iPad

Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears

(B) Try reset all settings

Settings>General>Reset>Reset All Settings

(C) Setup as new (data will be lost)

Settings>General>Reset>Erase all content and settings

FORCE IPAD INTO RECOVERY MODE

1. Turn off iPad

2. Turn on computer and launch iTunes (make sure you have the latest version of iTune)

3. Plug USB cable into computer's USB port

4. Hold Home button down and plug the other end of cable into docking port.

DO NOT RELEASE BUTTON until you see picture of iTunes and plug

5. Release Home button.

ON COMPUTER

6. iTunes has detected iPad in recovery mode. You must restore this iPad before it can be used with iTunes.

7. Select "Restore iPad"...

Note:

1. Data will be lost if you do not have backup

2. You must follow step 1 to step 4 VERY CLOSELY.

3. Repeat the process if necessary.

How much storage doe you have on your ipad2?  And how much of it is free?

Hardware issue my ***. After updating to IOS8 I got exactly the same issue. The iPad has been functioning fine for the past 2 years and is rarely moved from its location but now it crashed on 2 occasions and got caught in a reboot loop for 30 minutes. I noticed the 2nd crash was caused by an iMessage coming in while I was using another app. Possibly Notification Center tripped up the code. ps. I work in software testing and app development and this problem was most definitely software in origin. If it was hardware it would crash at any time but both crashes were caused by code being triggered.

There are several problems that many iPad 2 owners (including me) that have updated to iOS 8 are experiencing. Just do a google search and you will see. Another common one is loss of cellular access. Some suggested solutions may offer temporary fixes, but then the problems reappear. The only real solutions are downgrading to iOS 7.1.2 or waiting for Apple to figure out what is wrong with iOS 8 and releasing an update that addresses the errors/issues.

My iPad2 is also toast. itunes will not recognize it - either turns on and shuts off or simply shows the logo for 3 minutes then shuts off.

It's dumbfounding they could have messed up an upgrade this badly...all the other ones were very smooth for me.

After doing a factory reset and restoring from my itunes backup, my iPad 2 has become more stable and is not freezing up so far. Prior to this I was getting a random black screen. If I tried resetting it would go the the Apple startup screen and then to the black screen and remain there. Programs were crashing and freezing as well.

The cellular No Service problem has not been fixed. Turning the iCloud Drive on and off does seem to be a temporary fix. I will have it set on "on" and it the cellular connection will work for awhile. Then it will stop working and I will get the No Service again. At this point if I switch the iCloud Drive to "off" the cellular service will be restored for awhile. Then eventually it will lose cellular service at which point I switch iCloud Drive back to "on" and service is then restored.

Using the connect to iTunes procedure with pushing the home button while connecting the cable was able to complete a recovery.

I'll post again if I run into significant problems later in the day.

Basically I think the original iOS 8.0.2 install didn't work and that caused a hanging reboot.

II'm seeing the same issues on my iPad 4, no problems before IOS 8 upgrade. Won't ever upgrade so quickly again!

See this forum for some hopeful news and ideas for ipads2 owners:

Re: My ipad 2 ran great on with IOS 7. Now with IOS 8 it is slow and choppy and full of error messages. Is this Apples way of forcing my IPad2 into obsolesence?
