This thread may look like another massive how to root your device by downgrading and bla bla bla..... But I have found a new app/solution that will help you root your device!
What to do:
1: Go to this thread: http://forum.xda-developers.com/show....php?t=2783157 And download the application called TowelRoot.
2: Install the app and open it and press the button.
3: Phone will reboot within 15 seconds.
4: When rebooted your phone has root. To be sure you can download the app RootChecker from Play store
From here you have 2 ways to install a proper SuperUser app:
1: Install a custom recovery see: http://forum.xda-developers.com/show....php?t=2649923
2: Download the SU from here: http://download.chainfire.eu/447/Sup...SU-v1.99r4.zip
3: Flash it via recovery
1: Download the SU .zip (see above)
2: Put it on SD card and unzip it
3: Install the SU app and update the binaries Normal
From now on you have full root so you can install a custom recovery and run apps that need root.

Q: Will this work on my C5302 or C5306
Q: Do I lose my warranty
A: No, depends on the way the service center handels this. So to be sure you can reflash the stock rom to fully remove root (or unroot via SU app)
Q: Will this work on any ftf
A: Yes, it will work on all ftf with a kernel that has been build before 3 june (see towelroot thread)
Q: SOS my phone is bootlooping!
