FAQ’s before you install the I545VRUFNK1 4.4.2 Verizon Galaxy S4 Stock Firmware

Will this trip KNOX warranty void flag counter to 0×1?
Nup, this is an official and signed firmware from Samsung, so flashing official firmware will not trip KNOX.

If your device is currently rooted you will lose root after flash, but you can still root it again anytime you want.

Disclaimer: Use of this method is solely at your own risk! Please proceed with precautions, for we will not take any responsibility if anything happens to your device by using this guide.

• Make sure to recharge your Samsung Galaxy S4 SCH-I545 is or at-least still have around 40% remaining battery power.
• Stock Firmware packages comes in two formats the ‘Full-Wipe’ (delete your stored data after flashing) and the ‘Non-Wipe’ (it doesn’t delete your stored data) but it is highly recommended to make a back up all important files stored from your phone’s internal memory – contacts, messages, etc. before flashing no-matter if it is Full-WIpe or Non-Wipe, just to be safe and ensure that your stored data are in safe if something went wrong during the flashing process.
• Use a PC or laptop that runs in Windows OS, with a good and perfectly working USB serial port. Odin will not work on MAC OS.
• Use the supplied USB cable for your Samsung Galaxy S4 SCH-I545.
• Enable USB debugging from your phone’s settings –  Settings>>About Phone>> then scroll down to the build number and tap that number for around 7-times ’til the Developer option appear.

Run and Configure Odin
