Since the Samsung Galaxy S Advance (I9070) was upgraded to Android 4.1.2 Jellybean, many clients updated their phones. Others also went ahead and rooted their devices so that the warranty is reinstated since rooting a device deems the warrant void. With time though, users may want to return to stock which means they’d have to unroot the device.
How to Unroot Samsung Galaxy S Advance (I9070)
- Ensure that the device you want to unroot was previously rooted and that its battery is fully charged. Have a PC with you and a USB cable.
- Back up all the essential files that you do not want to risk losing.
- Download the following files from the links given and save them to your desktop:
a) Stock Firmware from HERE
b) ODIN from HERE
- Now to the main unrooting process, extract the files from STOCK FIRMWARE and ODIN and place them separately on your Desktop.
- Launch the ODIN executable file by double-clicking on it.
- Select the Stock firmware you extracted from the archive by clicking on PDA button in the tool.
- Ensure that the Auto Reboot and F. Reset Time are the only options checked in the tool. That means you uncheck the Repartition box if by any chance it is checked.
- Switch off the phone and reboot it to ‘download’ mode. To do so, press and hold the VOLUME DOWN, HOME and POWER buttons together.
- Turn on the USB Debugging on your device by following the path ‘Menu>Settings > Applications > Development > USB debugging’ and ticking the USB Debugging option box. Using the USB cable, connect your device to the PC.
- Flash the firmware by clicking on the ‘start’ button in the ODIN file.
11. Your device should automatically reboot and that should conclude your unrooting procedure.
