My mobile phone Samsung SM-G3588V will be displayed when the system is updated after I get root (your device has been modified and the software cannot be updated.

According to the situation you described, after the Samsung mobile phone is rooted, the permissions of the mobile phone have been changed when it is connected to the Kies driver software, and it is usually not supported to upgrade the system software. If the previous system software was refreshed by a third-party software, the permissions of the mobile phone have been changed, and it is impossible to restore the permissions of the mobile phone again. Therefore, in order to protect your rights and interests, we recommend that you do not obtain root permission. If there is a problem with the system, please bring the purchase invoice, maintenance card and machine to Samsung Service Center, and the engineer will check and handle the machine.
