I recently tired to root my s4 using the motochopper method. I soon realized when i opened superuser that it did not root especially when i used rootchecker to see if it had been rooted. Through more research I realized that there are no roms for MF3 or custom recovery yet. My question is what do I do know that I have superuser on my phone? Or what would I do when MF3 is ready to be rooted correctly? thanks for the help
