- Perform a factory reset if necessary.
Safety Tips for Flashing OTA Files
- Always use a fully charged battery to prevent interruptions.
- Avoid disconnecting the cable during the update process.
- Use official OTA files only to avoid device bricking.
Why Choose the OTA Update Over Full Firmware Flash
The OTA update is typically smaller in size and easier to install compared to a full firmware flash. It preserves user data (when not performing a full wipe) and minimizes risks of flashing errors. However, if your device is severely corrupted or bricked, a full firmware flash may be necessary.
