If that doesn’t work, use an unjailbreak app. The Universal unroot app available on the Play Store can unjailbreak many Android devices. Although you have to buy it for 20,000 VND, this software can be very useful. However, it is not available for Samsung devices (See next section).
Unjailbreak Samsung Galaxy
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/f0/Unroot-Android-Step-16-Version-4.jpg/v4-460px-Unroot-Android-Step-16- Version-4.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/f0/Unroot-Android-Step-16-Version-4.jpg/v4-728px-Unroot- Android-Step-16-Version-4.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Get the original operating system for your device. To unjailbreak your Galaxy device, you will need the original operating system for your device and carrier. You can find them in many places online. Use the search engine, type in the Galaxy model name, carrier, and the phrase “original operating system”. Unzip it after downloading and find the .tar.md5 file.
- Note: This method will not reset the KNOX counter, which is Samsung’s way of determining if your device has been jailbroken or tweaked. At this point, there is a way to jailbreak without making the KNOX counter jump. However, if the device is jailbroken using older methods, resetting the counter is completely impossible.
