Are you on 4.2.2? If so, the only way to root at the moment is to follow the pwnmymoto steps 100% PERFECTLY. And when you say you tried using ADB do you mean you tried to push the files(pwnmymoto.jar + su) to your sd using ADB and then use telnet and all that fun crap?

Anyways, but if your phone's version is less than 4.2.2 I believe the app should install as a normal one would.
