all you have to do is root it, all rooting does is change permissions, there is no need for data wiping or cache wiping.

all you need to do is just root and continue to do what you do.

Unfortunately, the DInc2 can only be rooted on certain versions of the HTC Sense - Android software. You will need to check what version you are on and use the respective root guide. By downgrading, you will essentially be performing a factory reset on your phone.

Therefore, I strongly suggest that you use an SMS Backup tool (I use SMS Backup & Restore https://play.google.com/store/apps/details?id=com.riteshsahu.SMSBackupRestore&hl=en ) to make a backup of your text and picture messages. I would also use any in-app backup function (many have an option to backup your settings and/or data as well). Finally, I would make sure you have your phone set up to sync your settings with google. This will backup your wifi access points and more.

Once you have rooted your phone, I very strongly suggest you make a nandroid backup before doing anything else. This can and should be used as a "last resort, everything else failed" restore point.

If you have any other questions, please let us know.

I used PDANet to tether my computer so I could root my phone.
