Re-installing OS on Samsung S4

[UltraJ]

The OS recently was corrupted on my AT&T Samsung S4. The solution is to reinstall the OS which is what I had a cell phone repair shop do a couple of years ago to a Samsung S4 Active. I've been phoning repair shops and most of them don't know how to reinstall the OS and they tell me that they will be google the solution after I leave my phone there.

I've never installed a a mobile OS before but from my research the tool to use on Samsung phones is the Odin3 software. I've been trying to find a suitable Android 4.x (ideally 4.4.4) OS to install on my phone but each 1.x GB download I've tried has failed. Where can I find the binaries to restore the phone? Could I install an OS from the Android Open Source Project (https://source.android.com/)?

Any help would be greatly appreciated.

Welcome to Android Central! Are you looking on SamMobile? https://www.sammobile.com/firmwares/. Here are steps to flash using Odin: http://forums.androidcentral.com/am...w-flash-stock-rom-via-odin-new-interface.html

Also, have you tried bringing the phone to your nearest Best Buy and asking the Samsung rep if they can reflash the firmware?
