Dear Readers!! Here but I bring you a fresh update for you. In my previous article, I informed you the steps to Flash Android 5.0 Lollipop LXE22.39-6 to Motorola Moto X Pure edition XT1095. Now in this article, I shall let you know how to flash the latest Android KitKat VRUFNK1 Firmware to your Verizon Galaxy S4 SCH-I545 Smartphone. The firmware has been rolled in USA now and is expected to hit the other corners of the globe soon. The firmware is dubbed as I545VRUFNK1 and is available only for the users of USA based Verizon Galaxy S4 users. If seen from features point of view, this update is supposed to bring a few changes in your device. Also it will fix the existing bugs in your Galaxy Note if you experience any.

If you are a user of the said android device and residing in USA, then you can upgrade your device to the next level with the new KitKat firmware via both OTA and manual update methods. Remember, this update is meant only for the said countries and hence must not be used even for equal device in other region. Now question arises, how to update? Very simple. Since it’s an OTA update, the firmware will be pushed to your device over-the-air and then you can flash it in your device by downloading it and following the appearing instructions on the screen of your Galaxy S4 device.
