I am trying to do a full system image backup of a Samsung Galaxy Tab 4. It is unrooted at present, and is running Android Kitkat 4.4.2 . I have no desire of rooting it as of now.
I have tried creating a full image backup of the device using the ADB (Android Debug Bridge) method (adb backup -apk -shared -all -f C:\backup.ab), which looks like it works, but when it completes, no backup files are created (Although the backup process is shown as having been completed).
Can anyone either offer advice on why the adb method doesn't work, or present an alternative solution to this? The end result should be a full backup image (including all apps and data) that I can use to restore the device back to its exact backup state.
