Modern car DVRs, such as the Xiaomi 70mai Dash Cam Pro, are complex electronic devices with their own operating system. During active use, especially when working in continuous recording mode or using memory cards with a high filling rate, the gadget can encounter software failures, this can manifest itself in the form of an interface freeze, a refusal to record video or errors on the screen.
Reboot is the universal and most effective method of eliminating temporary software errors. Unlike a full reset to factory settings, a simple restart does not delete your video recordings and personal settings, allowing you to only clear RAM and restart system processes. Understanding the different methods of restarting the 70mai Dash Cam Pro is necessary for each owner to quickly solve problems along the way.
In this article, we will take a look at all the available ways to restart a device, from a standard power outage to forced reset via hidden buttons. We will also look at typical scenarios where a conventional shutdown does not help and a deeper intervention will be required.
Standard procedure for restarting through power outage
The easiest and safest way to restart the Xiaomi 70mai Dash Cam Pro is to physically disconnect the device from the power source. Since this recorder does not have an integrated battery and operates exclusively from the on-board network of the car or Power Bank, breaking the power chain is equivalent to turning off the computer, which requires removing the USB cable from the device’s connector or disconnecting it from the lighter.
Wait at least 10-15 seconds after the power is turned off, and it takes that time for the capacitors inside the electronics to be completely discharged and the residual current to disappear. If you turn on the device right away, some processes in the memory may not clear and the error persists. Make sure the screen is out completely before you resume the power supply.
Reconnection must be made to a serviceable USB port with sufficient current. Often problems with cyclic reboot arise precisely because of unstable power supply or use of poor-quality cables. If after switching on the device booted correctly and recording began, then the problem was temporary.
⚠️ Warning: Do not pull the power cable sharply and forcefully so as not to damage the Micro-USB or Mini-USB connector on the recorder body, as it is subject to mechanical wear and tear.
Forced resetting with the Reset button
In situations where the 70mai Dash Cam Pro touch screen has stopped responding to touch or the device has got stuck, a standard power outage may be inconvenient or impossible without removing the mount. In this case, the Reset hardware button comes to the rescue. It is located on the device body and is designed to force reboot or reset settings.
To perform a soft reboot (without losing settings), you need to find a small hole, usually signed as Reset. You will need a thin object, such as an unbended clip or a special needle, coming with a kit. A short press (about 1-2 seconds) before the moment of vibration or sound signal will cause the system to restart.
It is important not to confuse short-term pressing with long-term retention. If you press the Reset button for 5-10 seconds, the device can go into recovery mode or perform a full reset to factory settings, which will delete all user data.
- 🔹 Find the Reset hole on the lower or lateral face of the body.
- 🔹 Use a thin metal object to press.
- 🔹 Press and hold. 2-3 second-to-beep.
- 🔹 Release the button and wait for the logo to load. 70mai.
Reboot when the interface freezes
One of the frequent problems of users Xiaomi 70mai Dash Cam Pro is the hanging of the GUI. The screen may burn, but stop responding to swipes and clicks, or the image is frozen on the last frame. In such cases, the system often continues to work in the background, recording video, but control is blocked.
Before you resort to radical measures, try a "soft" reboot through the menu if the touchscreen is partially responsive. Go to Settings → System settings → Reboot. However, if the sensor completely ignores commands, the only way out is a time-experiencing power cycle.
Sometimes freezes are caused by overheating of the processor. If you notice that the problem occurs after a long stay in the sun or in hot weather, let the device cool before re-energizing. Overheating can cause trottling and software failures that are corrected only after the temperature normalizes.
☑️ Actions when getting stuck
Solving the cyclical reset problem
The 70mai Dash Cam Pro is constantly turned on, shows the logo and switches off again, called a cyclic reboot loop, a serious symptom that can indicate damage to the memory card file system or a critical error in system files, and ignoring this problem can lead to complete failure of the device.
The first step in the boot loop is to eliminate the memory card from the equation. Remove the microSD card and try to turn on the recorder without it. If the device boots up and gives a message that the card is missing, then the problem is in the drive. Most often the memory card has sector errors or does not meet the requirements for write speed.
If the device is not doing well without a memory card, you need to format the drive. It is recommended to use formatting through the menu of the registrar itself: Settings → Memory settings → Format. This will create the correct file structure necessary for the 70mai Dash Cam Pro to work.
⚠️ Attention: Cyclical reboot may be caused by memory card incompatibility. Use only class cards U1/U3 up-to-volume 64 GB (for old firmware) or 128 GB (for new), from proven brands like Samsung or SanDisk.
The table below shows the main causes of cyclical reset and methods for their elimination:
| Symptoms. | Probable cause | Method of decision |
|---|---|---|
| Download to the logo and turn off | SD File System Error | Formatting a map in a device |
| Permanent restarts without a card | Power supply failure | Replacement of cable or adapter |
| Shutdown in 10-20 seconds | Overheating or software failure | Refrigeration and flashing |
| Screen blinking at start | Lack of tension | Checking the cigarette lighter's contacts |
Reboot after firmware update
The process of updating the Xiaomi 70mai Dash Cam Pro software is a critical step that often requires manual restarts to complete the installation. Once the registrar downloads and installs new files, it may not turn on automatically or require confirmation to apply the changes.
Usually, after a successful update is installed, a notification appears on the screen. In most cases, the device will suggest rebooting yourself. If this does not happen within 1-2 minutes, you must perform a forced shutdown. Do not interrupt the update process if the indicator flashes or the progress bar is displayed on the screen.
After the first turn on after the firmware, the system can work slower than usual, as the files are re-indexed and new parameters are set up. Give the device 5-10 minutes to stabilize the operation. If the recorder is unstable after the update, it makes sense to reset to factory settings to eliminate conflicts of old configuration files.
Failure prevention and proper operation
To minimize the need for frequent reboots 70mai Dash Cam Pro, you should follow a number of rules of operation. Electronics of automotive gadgets work in extreme conditions: temperature changes, vibration and voltage surges in the onboard network negatively affect the stability of work.
It is recommended to check the status of the memory card once a month and format it if necessary, and also make sure that the power cable is securely fixed and does not overflex, as poor contact can cause micro-breaks of the circuit, perceived by the system as commands to restart.
Regular firmware updates via the 70mai app on your smartphone help eliminate known bugs and improve compatibility with various memory card models. Automatic updates can be configured in the menu to avoid worrying about new versions of the software.
- 🔸 Use original power cables or certified analogues.
- 🔸 Avoid overheating the device, do not leave it under direct sunlight without the need to.
- 🔸 Periodically clean the lens and body from dust and contamination.
- 🔸 Keep an eye on the memory card, although cyclic recording should control this.
