Thanks for the video, I am sure it will help a lot of people. However, it has been known for a little while now that the Galaxy gear would be based on 4.2.2 firmware so it shouldn't be any surprise that it works with the AT&T S4.
SGH-I337 (AT&T) 32GB
P-ROM (1st Gen.), De-Odexed, AMDL
Auto-LOKI OUDHS CWM
Make sure you read and understand the "PINNED" threads in the "General" and "Q & A" sections of the AT&T S4 forum BEFORE you ask for help. Use the forum's "search" function to find posts with additional information. You should not expect others to help you if you haven't tried to help yourself first. Also, read, understand, and follow the "XDA" rules.
