Here is the full Odin flashable Android 4.3 build I545VRUEMJ7 stock firmware for Verizon Galaxy S4 (SCH-I545). The I545VRUEMJ7 was rolled out on October 28 and brings new features like Samsung KNOX and several bug-fixes. This is only for those who wanted to restore back their devices to original factory stock firmware. The stock is useful for fixing unwanted bootloops caused from any modified ROM.
So here you go: VZW_I545VRUEMJ7 Link
Device: Samsung Galaxy S4 SCH-I545
Version: Android 4.3
This stock firmware came in single file format, so you may only load it on Odin’s AP slot. You may used Odin3_v3.09 for flashing the 4.3 stock firmware.
Again, use of the stock firmware is solely at your own risk! Don’t ask me any issues about flashing. This should be for advanced users only, and I am confident enough that they already knew the drill and knows exactly how stock ROM to be used for.
