Galaxy S4 SPH-L720 Will not turn on

[AC Question]

I was trying to transfer apps and data to and external SD card so i could have more room on my phone. However, when i tried to open the app my phone would say that the apps aren't downloaded. I used TWRP and used a backup. Now my phone says could not do normal boot. ODIN MODE. I ruined the warranty by rooting it and Best Buy won't accept it. Please Help!!!

So can you boot into Recovery? Try flashing the stock ROM using Odin: http://forums.androidcentral.com/am...w-flash-stock-rom-via-odin-new-interface.html
