The great thing about the Android platform is that you can customize it anyway you want to. If you don’t like the stock ROM running on your device then you can replace it with any compatible ROM that you like. One prerequisite to this is that you must have a rooted device first.
After trying out other ROMs some Samsung Galaxy S4 owners may want to revert back to the original stock experience. If you own the Samsung Galaxy S4 GT-I9500 & GT-I9505 models here’s the procedure on how to unroot the device.
- Make sure you have installed the Samsung Galaxy S4 GT-I9500/5 USB drivers on your PC (the simplest way to do this is to install Kies)
- Enable USB debugging mode which is deactivated by default
- Your S4 should have 70-80% charge remaining
- Your S4 should be factory unlocked
- You should backup your important data first
- Make sure that Kies program is not running & disable antivirus
- Turn OFF your S4 then go to Download Mode by pressing and holding the Volume Down + Home Buttons together for few seconds followed by Power button then proceed with volume up.
- Download Odin then open it on your PC and connect your Galaxy S4 to your computer.
- Once your S4 is successfully connected to your PC, the ID:COM box on ODIN will turn blue (or yellow) and will show the COM port number.
- Unzip the downloaded firmware you will get a Home.tar file.
- Click on pda (in Odin) and choose the file “Home.tar”
- Check “Auto Reboot” and “F. Reset Time” options and make sure that “Re-Partition” is unchecked
- Click on Start button in ODIN window to start the flashing process. It’s going to take a few minutes to complete
