The iRecovery Stick shipment box contains the iRecovery Stick and a USB cable that is compatible with the iPhone 3GS, 4 & 4S.The iRecovery Stick is compatible with Windows XP and 7, and provides an easy-to-use user interface. The iRecovery Stick does not support vmware/virtualbox environment and Linux &Mac OS X operating systems. Also, it is mandatory to turn off the antivirus software running on the Windows OS for better data recovery. The iRecovery Stick is a portable and simple-to-use USB flash drive which contains the recovery software iRecoveryStick.exe. Recovery software included in the iRecovery Stick can be installed on to the hard drive or it can be executed directly from the USB drive. The image below displays the contents of the iRecovery Stick USB drive.
Installation of the iRecovery software is well documented in the iRecovery Getting Started manual located in the USB flash drive.
Data Acquisition and Recovery from the device
The iRecovery Stick is very simple to use. Simply connect the iPhone to a Windows-based computer with the USB cable and then connect the iRecovery stick to the same computer through a USB port. Once the two devices are connected, run the iRecoveryStick.exe program. The Welcome screen of the iRecovery stick software is shown in the image below:
Once open, click on the Start Recovery button (highlighted in the above image). Then the recovery software prompts to choose connected device as shown in the image below.
Click on the device to start the recovery process (shown in the image below). The data recovery process will take several minutes to a few hours to complete based on the size of the iPhone disk. During a test on an Intel i5 2nd generation processor laptop, it took 14 minutes to recover 256MB data from the iPhone 4.
The recovery process acquires existing data and recovers deleted data from the iPhone, but the majority of the data will be the normal user’s data which has never been deleted. Once the recovery process is completed, then it immediately displays all the data recovered from the iPhone (shown in the image below). The recovery process downloads the existing contents of the phone such as contacts, call history, text messages, calendars, notes, pictures, multimedia and all other data like Safari history, Safari bookmarks, GPS history and application cookies. It also recovers different types of deleted data including text messages, contacts, call history, and calendar entries. The iRecovery Stick is not capable of carving the file system, so it can only recover the deleted data from the Sqlite database files and does not recover the deleted files from the file system, i.e. it does not recover deleted photos.
The user interface also provides an option to generate an easily readable report or to export the recovered data to Excel sheets. During a test, the export to Excel option took more time than the actual recovery process.
The iRecovery Stick does not have the capability to bypass the iPhone passcode. So if the device is protected with a passcode, unlock it before connecting it to the computer for recovery.
Data Acquisition and Recovery from the backup
The iRecovery Stick can also recover data from the iTunes backups. In general, the iTunes backup contains a copy of everything on the device like contacts, SMS, photos, calendar, music, call history, notes, network settings, Safari bookmarks, cookies and application data, etc., so the iRecovery stick recovers the same types of data that it can recover from the iPhone itself. To recover data from the backups, run iRecoveryStick.exe and load the iTunes backup files created in Windows. The Welcome screen of the iRecovery Stick software is shown in the image below.
Click on Start Import from iTunes Backup button (highlighted in the above image). Then the recovery software prompts you to choose the specific iOS version as shown in the image below.
Clicking on the specific iOS version prompts the user to open the existing iTunes backup as shown in the image below. In general, iTunes backup gets stored in these locations:
Windows XP – C:Documents and Settings[user name]Application DataApple ComputerMobileSyncBackup
Windows 7 – C:Users[user name]AppDataRoamingApple ComputerMobileSyncBackup
Once the backup is selected, the recovery process starts. The data recovery process will take several minutes to a few hours to complete based on the size of the backup files. During a test on an Intel i5 2nd generation processor laptop, it took 15 minutes to recover 300MB data from the iTunes backup.
Once the recovery process is completed, it immediately displays all the data recovered from the backup files. The recovery process extracts the existing contents from the backup such as contacts, call history, text messages, pictures, multimedia and all other user data like internet browsing history & application cookies. It also recovers different types of deleted data from the backup including text messages, contacts, call history, calendar entries and notes.
The iRecovery stick can only recover data from the iTunes normal backups and it does not work with the iTunes encrypted backups.
