Root [Verizon] HELP unrooting

[Hardstyle]

I am trying to unroot my verizon s4 and i tried 2 different files and each of them fail in ODIN. Can somone PM or reply with a link for a stock ROM so i can unroot my S4 i need to sell it tomorrow. It won't let me do a factory reset when im rooted. IDK if this matters i originally rooted when i was on MDK then took the OTA update to ME7 so im currently on ME7. Now i cant turn my phone on it just boots to the screen that saysfirmware upgrade encountered an issue. please select recovery mode in Kies & try again.

You might have to take the phone to a participating Worst (Best) Buy to have them force a reload of the OS.
