D415 root needed Towel root not supported

Hi everyone,

just tried to root my Tmobile USA, D415. however it says device is not supported. Did lolipop break root via this method? Any alternative methods?

While I am reading all the threads on how to do this, I want to make sure I'm not blindly using an outdated method. A pointer would be greatly appreciated.

Also, which method of installing a custom room would you guys recommend for installing a custom recovery?

I will continue to read for possible solution.

Thank you in advance :D
