Pro Tips
You can perform quick updates through the Firmware Finder and download the latest firmware for your device using this application. The software does not require any root privileges or an unlocked bootloader. In addition, using it is almost impossible to install the wrong firmware version on a smartphone. Before any firmware, make a backup, fully charge the phone and connect to fast Wi-Fi.
For advanced Android users, there may be situations when you need to flash a Huawei modem, but only with certain files from an OTA update. For example, if the device accidentally became bricked, and the user knows exactly what he was flashing, he will be able to do the wrong actions and restore the device.
Reasons why Android phones freeze:
- The installed application is not compatible with the phone's operating system.
- Error reading data from SD card.
- Opening corrupted files, APK files, or application files stored on external media such as an SD card may cause your phone to freeze.
- Viruses or malware. This is one of the most common situations that affects the systemphone security.
- Errors due to incorrect ROM installation.
Huawei Android phones are great for ROM customization and flashing, however, using the wrong, incompatible, or badly coded ROM with many bugs can significantly affect the stability of the phone, so the user will need to be extra careful.
