Locate the upginfo file inside the unzipped firmware folder on your computer. Open it with a basic text editor (like Notepad). You will see various parameters with values of either =y or =n .

The simplest way to update your Ddpai Z40 is through the official smartphone app. The manufacturer recommends this method because it is automatic and requires no technical steps on your part.
Power on the dashcam using a stable power source (such as your car charger or a 5V/2A wall adapter). The camera’s LED indicator will begin flashing rapidly, indicating the update is in progress. Do not cut the power during this time.
If the app is unstable or you are unable to connect to Wi-Fi, you can perform a manual update using a computer and the SD card 1.2.3 .
The app will push the downloaded firmware package to the Z40. The dashcam will announce that it is updating. Do not turn off your car or unplug the power cable during this process.
Turn on your car ignition to power up the Z40. Open your phone's Wi-Fi settings, connect to the dashcam’s Wi-Fi network, and open the DDPAI app.
Once you have the file, follow the appropriate set of instructions below.
