With this tool, you can completely backup your device without root or unlocked bootloader.

I have tested it so far only with my Galaxy Nexus, but it should also work with other devices running Android 4.0+.

So you can unlock your bootloader without losing your data.

With version 1.1, not all parts of the program will be downloaded, only the necessary.

The most tools in the "Tools" section are for the Galaxy Nexus, but more devices will follow soon.

Now the final release of v2 is out!

The UI is complete, it's much easier to use.

If you use v1.2.2 you don't need to copy the UBT to platform-tools.

It would be nice if someone would do a tutorial for v2 :)
