Why do we need to upgrade the firmware?
After a mobile phone is sold, hardware is maintained by the maintenance center and software ismaintained by upgrading the firmware. We optimize, add or change functions of the mobile phone by upgrading the firmware. By upgrading the firmware, you can obtain the latest and the better functions.


Would data be lost after the firmware is upgraded?
Firmware upgrade will not lead to data loss. However, in the following cases, ensure that data is cleared during the upgrade. If the data is not cleared, the mobile phone may fail to start up.
1.  The mobile phone has been downgraded.

2.  The mobile phone has been rooted.

3.  After security software was installed, the software was signed by the Android operating system to fix security holes.

Clearing the data will cause loss of personal data such as contact information. User data includes contacts, SMSs, applications and all content of the mobile phone except data stored on the SD card. Please ensure that important data is backed up and synchronized.
In other cases, there is no need to clear data before firmware upgrade. If user data is not cleared before the upgrade, the user data such as contacts, chat history and game progress is not lost after the upgrade. However, you are still advised to periodically back up data in case the mobile phone fails to be flashed or gets lost.

Preparation before flashing:
1. Back up important data.
2. Ensure that the battery is sufficient.
