2. Preparing for a Firmware Update

Before updating, spend a few minutes preparing the dash cam and your Android phone. This reduces the risk of failures or data loss.
2.1 Ensure Stable Power
Interrupting power during an update is risky. To stay safe:
-
Perform the update with the engine running or while the ignition is on, so the dash cam has a stable power supply.
-
Avoid updating when the vehicle is about to be turned off or when the battery is weak.
-
Do not unplug the power cable or remove the SD card during the update.
A stable power source is the single most important requirement for a clean firmware upgrade.
2.2 Back Up Important Footage
Most firmware updates do not erase video files, but it is still wise to back up any critical clips first:
-
Connect your Android phone to the dash cam via Wi-Fi.
-
Use the 70Mai app to download important videos (especially accident footage, parking incidents, or other evidence) to your phone.
-
Optionally copy them from your phone to a safe place such as a computer or external storage.
Once your important clips are safe, you can proceed with less worry.
2.3 Check SD Card Health
Firmware files are often stored temporarily on the SD card:
-
Use a high-quality, high-endurance microSD card.
-
If the card has frequent errors or old formatting, consider:
-
Backing up important files.
-
Formatting the card from within the dash cam menu before updating.
-
A healthy card reduces the chance of incomplete or corrupted firmware files.
3. Checking Your Current Firmware Version
