Thank you for reaching out. To address the problem you are encountering, we recommend trying the following steps:
Step 1. Connect your device to your computer using the USB cable provided with your device, and then open Smart Switch on your computer.
Step 2. If a software update is available, Smart Switch might automatically prompt you to update the software or will display an option to update.
Step 3. Click Update and use the on-screen prompts to download the necessary files.
Step 4. Click OK to proceed. Your device may turn off and on a few times during the update process. When the update is complete, the device returns to the Home screen.
You’re going to need a copy of Smart Switch installed on your computer and your mobile device. Using Smart Switch’s computer version, update your device with the latest software.
