Guided Access mode after a reboot on iOS 9 vs. iOS 10 vs. iOS 11

iOS 11 Update: Just tested on iOS 11, and it stays in guided access mode after a reboot. Same with iOS 11.1.

Update: Just saw an iPad with 10.3.3 not get out of guided access mode after a reboot.

Just a quick observation based on testing:

If you're in Guided Access mode on an iPad running iOS 9.3.5 (say, an older model that can't install iOS 10 and above), and you do a forced reboot (hold home and power buttons until the Apple symbol appears), the device stays in Guided Access mode.

If, however, you're in Guided Access mode on an iPad running iOS 10 (and perhaps in future versions?) and do a forced reboot, the device gets out of Guided Access mode.

P.S. I was able to use this to help a student out who was stuck in Guided Access mode on an older iOS version—updated it to iOS 10, rebooted, and then the iPad was out of Guided Access mode, and a new Guided Access mode passcode could be set.

Troubleshooting “iTunes could not back up iPhone / iPad because an error occurred”

If you get an unspecified error when backing up your iOS device, there are a myriad of potential solutions (anything from looking for phantom apps on your iPhone/iPad to ignoring a local computer backup and going for an iCloud backup instead). Apple also has an official guide for things to try.

For the one user I saw experiencing this problem, none of those solutions helped. One simple thing did, though—using a different USB port on the laptop. The other USB port seemed to work fine for just about everything else, just not backing up the iPad to the computer via iTunes.

The iPad could not be restored. An unknown error occurred (9).

We've come across a couple of iPads that give you an error 9 when you try to restore them to factory settings, usually after the iPad gets disabled or has some other funky state that cannot be recovered.

Apple has its own official help page for errors, but we didn't find that much use (no, security software wasn't blocking anything).

In one case, the iPad hadn't been updated in a long time and wasn't able to jump up versions to 9.2 from whatever it was (more details on this type of situation at iOS 4.3.5 error 9 when updating to 9.0.2), and Apple stopped signing older .ipsw files, so you can't even manually download those and use those as intermediate updates to the final one.

In another case, it was simply a bad USB cable... or a perfectly fine USB cable for charging and general file transfers but apparently not good enough to do a factory restore on. I'd say for this type of recovery it's worth trying to find the newest, shiniest iPad/iPhone cable you can find.

Adding Google Apps “Other Calendars” to iOS

If you're using Google Apps for Education and add a Google account to Mails, Contacts, Calendars in iOS, you may notice only your primary calendars (and not "other calendars") showing up on your iPhone or iPad's Calendar app.

If that happens, just visit while logged into your GAFE account, and then check the box next to the calendar you want synced. That's it!

Get photos/music off an iPad or iPhone using Ubuntu Linux


These instructions work for iOS 8 (tested on both an iPhone and an iPad) using Ubuntu 14.04 (Trusty) and Ubuntu 15.04 (Vivid). The instructions will still likely work in other versions of iOS and Ubuntu, but your mileage may vary.

What's the problem?

If you take pictures with your iPhone or iPad and then plug your phone into your Mac, Photos (previously iPhoto) will import the pictures you took on your iOS device. It will not, however, easily allow you to copy random other photos that happen to be on your iOS device.

We recently had a user come in with an iPhone that had some pictures transferred from another computer with these pictures no longer living anywhere else, and so the user wanted the pictures backed up. Photos and iPhoto do not recognize and import random other photos that weren't taken with the camera.

There are plenty of paid-for utilities you can download that will allow you to copy photos and music off an iPhone or iPad, but if you'd rather save the money for other purchases, here's a little workaround that's cost-free.

Get Ubuntu Linux

Really, you can use any Linux distribution, since libimobiledevice is available for any Linux distribution, but we'll use Ubuntu for this example (and, handily, Ubuntu comes with libimobiledevice installed).

If you're a total Linux novice, you can read up quickly on how to get Ubuntu and how to make a bootable USB of Ubuntu. The instructions are a few years out of date, but the same basic procedure applies, and UNetbootin works on Windows and Mac OS X.

Using Ubuntu to rescue your photos (and music?) off your iPad or iPhone

If you're using Windows, make sure your BIOS or UEFI is set to boot to USB. If you're using Mac OS X, hold down the Option key at boot-up and then choose to boot from the USB stick (it may appear as just the word EFI).

You should get a boot menu similar to the following:

*Try Ubuntu without installing
Install Ubuntu
OEM install (for manufacturers)
Check disc for defects
You want to select *Try Ubuntu without installing. This will load Ubuntu into your computer's RAM and not affect your hard drive or SSD.

Once the live session is booted, unlock your iPad or iPhone, and plug it into the computer that has live Ubuntu booted on it. Ubuntu will throw you an error saying it can't connect to the iOS device, but that's because you have to say on the iOS device that the computer is trusted. Once you say the computer is trusted, you should be able to select the device from the file manager (you do not need to physically unplug and then re-plug in your device).

To find non-camera photos from a previous sync, go to nameofiOSdevice > PhotoData > Sync > 100SYNCD.

For previously synced music, go to nameofiOSdevice > iTunes_Control > Music. You'll see a bunch of folders labeled F##. Just copy all of them or the entire Music folder that contains them.

For Windows, Ubuntu can write directly to the NTFS drive if you want to copy the photos or music there. For Mac, you'll need a USB stick or something else to copy the photos or music to.
