![]() Prerequisites for creating a backup with Finder As a previous step, check whether the apps installed on the user?s device will require manual configuration after the restore process is performed. This is required because Finder also stores the device state in the backup, so, when you restore the device data, you also restore the previous, non-supervised state of the device.įinder does not store the settings of all the apps that exist on Apple Store. ![]() Finder: If the user does not use iCloud or wants to keep apps or types of data not supported by Apple?s cloud, you must create a backup of the mobile device by following a veryspecific protocol.If iCloud does not store all the types of data you want to keep, use the Finder app as explained in this article. To verify whether iCloud stores in the cloud all the types of data you want to recover after having enabled supervised mode, see this article. After the device has been formatted and placed in supervised mode, the user simply has to use their Apple ID to regain access to all their information. iCloud: If the user uses Apple's cloud storage service, it is very likely that you will not need to create any backups manually in this case, their documents, photos, and other items are not stored on the mobile device but are automatically stored in the cloud.To avoid this, you must use a backup and restore method that will vary based on the type of data stored and the backup software used: As a result, all apps and data stored on the device by the user are lost. When you configure an iOS device in supervised mode, you reset it to factory-default settings. Panda Security recommends that you use this procedure in a test environment and at your own risk before you try it in your live infrastructure, a s it contains multiple references on how to operate with a third-party manufacturer. The aim of this article is to provide you with a set of instructions to help you keep your iOS device data before you enable the supervised mode. I guess these devices aren't really usable until repaired anyway, so maybe Apple doesn't care.IMPORTANT INFORMATION YOU MUST READ BEFORE YOU START! I'm not sure whether or not this behavior is intended. In iOS 14.8 and earlier, these keys would quickly return with either empty or missing values, but in iOS 15, it seems to hang for way too long and eventually times out. Ideviceinfo hangs afterwards because there are certain lockdown keys related to the baseband / IMEI that hang whenever you try to get their value. The behavior is consistent regardless of whatever software is used to restore the device to iOS 15. Swiping up from the Hello screen opens up a blank white page instead of the usual Language selection screen, and after awhile, the setup assistant crashes or restarts itself. The phone lands back at the setup assistant, but as of iOS 15, the setup assistant actually breaks. I think iTunes / Apple Configurator do the same thing, or at least something similar. The baseband update fails at the end of the restore process, which I was ignoring in order to let the restore finish. Seems like these devices have baseband issues which exhibits new behavior in iOS 15. Would be interesting to hear if anybody else has seen this issue again it may not be related necessarily to idevicerestore if it turns out to be a problem within iOS 15. This has not failed yet, but that won't be an option anymore as soon as iOS 14.8 becomes unsigned. The only consistent solution I've seen so far is to downgrade the device back to iOS 14.8. ![]() ![]() However, after restoring it again via iTunes and later again with idevicerestore, the phone is back in this state. I have been successful in 1 case, using libimobiledevice, to restore one of these devices to iOS 15 and the phone regained its functionality. The device does not recognize this host". After an iTunes restore, iTunes will error out with "iTunes could not connect to this iPhone. Restoring these devices to iOS 15 using iTunes / Apple Configurator doesn't seem to alleviate the issue either. Interestingly enough, pairing with the device and using idevicesyslog seems to work fine, but ideviceinfo breaks along with other Apple tools that read device info. The restore is successful, and the phone lands back on the "Hello" screen, but ideviceinfo times out in idevice_connection_receive_timeout after 30 seconds. I have seen multiple scenarios where a device, after successfully restoring to iOS 15, can no longer retrieve device info via ideviceinfo, iTunes, Apple Configurator, Finder, etc. I'm not really sure if this is an issue associated with libimobiledevice, but I wanted to see if anybody else had experienced something similar ever since the release of iOS 15. ![]()
