Rooting in Android is the key to all kinds of system tweaking or optimization and visual customization. You need to have proper root access to be able to install root apps from the Play Store. In most cases rooting an Android device simply means losing the manufacturer’s warranty. However, people still root their device because they find the benefits of having root access irresistible.
The method of rooting devices from different OEMs differ in some way or other. It can be achieved using an automated script or an easy-root toolkit, by flashing a pre-rooted ROM, or by installing a flashable root package via stock or custom recovery. I have no idea what method you used to acquire root access on your phone or tablet, but if you have been facing issues with root privileges on your device, the tips provided on this page might be of some help to you.
Have you been facing “Root Access Possibly Lost” issue while trying to back up, restore a flash a ROM in CWM or TWRP recovery? Do you see “Root access missing” message on your rooted device when you open an app that requires root? Try one of the solutions suggested below to fix missing or lost root access issue on rooted Android devices
- First off, make sure that your device has been rooted properly. To verify root access on your device, try this free app:
- If you’re facing missing root issue just after rooting your device, open SuperSU and update SU binary if the app prompts you to do so.
- In case root permission issue is related to a specific app and it works fine with other apps, you might have accidentally denied root permission to that app. To fix it, go to device Settings> Applications> All> SuperSU and tap it. Then clear app data. Now open the app in question and grant root permission when prompted.
- Open SuperSU from your device’s app drawer, go to app Settings and try disabling and enabling it. Then reboot the device and try using root apps. If the lost root problem is not fixed yet, try the solution given below.
- Open SuperSU> Settings and tap the Reinstall option and select Continue.
- If your device doesn’t have a custom recovery like CWM or TWRP installed on it, you can try this solution.
- Download the latest version of Chainfire’s SuperSU flashable ZIP file: UPDATE-SuperSU-vx.xx.zip
- Unzip the file and open the extracted folder.
- Go to a folder called common and open it.
- Copy Superuser.apk to your device and install it. Then try using a root app to check if the problem has been solved.
- If you have a Samsung Galaxy device with KNOX on it, and you are getting issues with root access, the above solution might be helpful to you too. After installing Superuser.apk, open the app. When you see the following message, select OK: “Samsung Knox has been detected. This might limit root capabilities and cause annoying popups. Try to disable KNOX.”
- If your device has CWM or TWRP, download the latest SuperSU APK. Copy the zip to your device and flash it using Install option (in TWRP), or install zip from sdcard option (in CWM).
