You can only root using the htc method. It is in the stickies and 87 other threads. If you google root 1.5 hboot evo 3d it brings you to the XDA guide

 

i'm about to try this guide here so i can finally root, but it warns me to back up my texts, etc since the HTC method resets the phone. how exactly to i back stuff up?

 

are the texts really that important .. it took me about 3 hours to unlock with the htc way 2 weeks ago and i still cant figure out how to gain superuser rights

 

well it said texts and everything else. so i'm assuming that means contacts, pictures, apps, etc?

and the guide i quoted is supposed to help you with that

 

pictures are saved in sdcard, go to contacts and export to sdcard, i would not worry about texts
