Install M919UVUFOH3 T-Mobile Galaxy S4 SGH-M919, The Stagefright Fix Update

Stock firmware build M919UVUFOH3 that's the T-Mobile Samsung Galaxy S4 SGH-M919 update to fix the recent Stagefright vulnerability. If weren't to the said Android security flow, this device might not get any update anymore. As we've started  covering this phone way back two years ago, and so we'll have to finish it until it last.  An update is any update anyway, and I believed that there are still many folks out there still rocking this phone.

By the way, the ;M919UVUFOH3 is still in Android 4.4.4 KitKat base, and not the an Android 5.0 Lollipop. The T-Mobile Samsung Galaxy S4 SGH-M919 is the only device in the United States that did not get any Lollipop update. So those who might want to manually install the M919UVUFOH3 update, then just grab the stock firmware below.
