Software version is 18.104.22.168
I found instructions here: http://kfsowi.com/guides/root
If I understand them correctly, it is replacing the boot image with the older software version one.
Then rooting it.
Then replacing the boot image again.
My question is does replacing the boot image wipe the device?
I'm trying to root so I can either backup the clash of clans data with titanium backup to move it to another device.
Or so I can associate it with a google+ account.
So obviously I don't want to erase the data in the rooting process.
I tried backing up the data with Helium but it wouldn't backup clash of clans.
