These are the instructions to unroot Blu Studio 5.0 C HD smartphones. Once you are done unrooting your device, you can anytime choose to follow a rooting guide and grant those root permissions back on your device. In the mean time, you cannot install any of the apps which did require root like the ROM manager or the ROM Toolbox application. You may, however, still use the ordinary apps from the Google Play Store that are available to everyone.
- You must root the Blu Studio 5.0 C HD smartphone  before this guide is of any use to you. Without root access to the root file system, you have no reason to follow and unrooting guide. You should find your Android operating system is already locked.
- The following guide is made for the Blu Studio C HD only and will not unroot all other devices. The KingUser app can unroot more than one device; however, you’ll need to know that your device is compatible. The easiest way to know if your device is compatible is by knowing if you rooted with the KingRoot app or not. Those that did can also use this guide.
- You must still have the three apps on your device that you got when installing the KingRoot application. That includes the kingUser app and the KingMaster app. Those who deleted the three apps will need to install the KingRoot bundle once again and then open the new KingUser app.
BEFORE WE BEGIN

- You need not worry about the Developer Options menu being enabled, the USB Debugging Mode being turned on or the Unknown Sources box checked. You already have the KingUser app installed on your device from when you installed the KingRoot app. After installing the KingRoot one-click universal rooting tool, you got three new apps on your device — one of those is the KingUser which you need to open today during the guide.
