It often happens that we mess-up our devices while doing customizations or just editing a system file for better performance. If something like that has happened with you, unrooting should be a solution for you. What unrooting does is get your device back to the stock firmware replacing all the customizations and the edited files with the original ones. That way, your phone should behave normal and it will be as pure as it was when it was bought from a retail store.
Here’s how you can go about unrooting your Samsung Galaxy J1:
Files You Need
1. Download the Stock ROM for your Samsung Galaxy J1 to your computer. It’s the whole operating system that runs on your device. You will flash this ROM on your device in the following tutorial.
2. Download Odin to your computer. It’s a small utility that helps users flash various ROMs on a Samsung device.
3. If you don’t already have, get the Samsung USB Drivers installed on your computer before starting to unroot your device. It should help your computer to detect your phone.
4. This should only be done on a SM-J100F device.
Unrooting the Samsung Galaxy J1
1. First of all, get the actual files extracted from the archives. To do that, right-click on both the archives you have downloaded to your computer and select Extract here. The files will be extracted.
2. Open Odin by double-clicking on its file.
3. Once it launches, click on PDA and navigate to where you have saved the stock ROM and select it.
4. Repartition must NOT be checked in the Odin as it can cause issues in your device.
5. You can, however, checkmark the boxes that say Auto Reboot and F. Reset Time.
6. Turn off your device.
7. Turn your device back on in download mode. To do that, hold down Volume DOWN+Home+Power buttons at the same time.
8. Hit Volume UP when a warning message appears and you will go into the download mode.
9. Use a USB cable to connect your phone to your computer.
10. When the phone is connected, hit Start in the Odin and wait for it to flash the stock ROM on your device.
11. Once the ROM is flashed, your phone will automatically reboot.
12. You are all set.
Your Samsung Galaxy J1 is now back to the stock ROM. It is no longer rooted and you can’t install any root-requiring apps on it anymore.
