Unrooting your Samsung Galaxy Core 2 is useful in many cases. For instance, you may have apps crashing too often on your device and you believe it is all because of some modifications that you did to your device when you rooted it. Such issues can be resolved by unrooting and flashing back the stock ROM on the device.
Here’s how you can go about unrooting the Samsung Galaxy Core 2:
Files You Need
1. You need a Windows based computer to do this tutorial.
2. You should have Samsung USB drivers installed on your computer. If you don’t, download and install them first.
3. Download Odin to your computer. You’ll use it to flash the stock ROM on your device.
4. Download Stock ROM for the SM-G355H to your computer. It is what you will flash on your device.
5. This only works for the SM-G355H device.
