How Can I Root My GS4 Without Bricking It Again So... I've rooted all of my devices in the past: tablets and phones and 2 months ago I tried rooting my Galaxy S4 and bricked it, even though I followed an XDA video on how to root. 

I followed all of the steps exactly as instructed and still bricked my GS4. 

So... Is there any way/video/method that can help me root my new GS4 without bricking it this time? Or should I just forget about it?

I have the T Mobile SGH-M919 I believe
You cannot really root a bricked phone. However, assuming your phone is not currently bricked, there's a very straightforward tutorial by wwjoshdew that you can follow.
