The modern DVR is a complex computing device that, like any gadget, requires periodic software updates. Devices from Xiaomi and the 70mai sub-brand often ignore notifications about new firmware versions, which can lead to unstable work or lack of new features. Regular installation of current versions of software is not just a whim of the manufacturer, but a necessity for ensuring the stability of recording and correct operation of video compression algorithms.
The upgrade process can vary dramatically depending on your device’s specific model. Some devices, such as the 70mai A500S or A800S, support OTA (Over-The-Air) functionality, which allows you to download files directly over Wi-Fi. Other, more budget-friendly or specialized models may require manual intervention through your computer and memory card. It is important to understand what method is applicable to your gadget to avoid errors.
In this article, we will take a look at all the nuances of the process, from preparation to elimination of critical errors, you will learn how to use a mobile application correctly and how to flash the device manually if the automatic method does not work. Data security and file system integrity are a priority, so following the instructions will help to avoid turning the recorder into a brick.
Why you need to update the firmware of the video recorder
Many users mistakenly believe that if a device is stable, it is not worth tampering with its code. However, manufacturers including Xiaomi regularly release patches that fix security vulnerabilities and fix bugs that can only occur under certain operating conditions, such as an update that can fix an error that causes the recorder to stop recording sound or displays time incorrectly.
In addition to bug fixes, new software versions often include improvements in image processing algorithms, such as better noise reduction at night or better license plate recognition, sometimes adding support for new languages or expanding voice control functionality, making it more comfortable to use the gadget.
⚠️ Note: Using an outdated firmware version may lead to incompatibility with new versions of the mobile application, which will deprive you of the ability to view the archive through your smartphone.
Also worth noting is the optimization of memory cards, new recording algorithms help extend the life of the drive and reduce the risk of losing important video files at a critical moment, and the stability of the system depends on how relevant the software installed in the device’s memory is.
Preparation for the renewal procedure
Before any software manipulations are initiated, a number of preparatory steps must be taken to minimize the risk of failure and ensure the process is completed successfully, first of all, make sure that the battery of the device (if any, as in the 70mai Dash Cam Pro Plus+) is charged, or that the recorder is connected to an external power source.
The second critical step is to check the status of the memory card, the file system should be in order and the free space should be sufficient for temporary update files, and it is recommended to format the drive through the menu of the registrar before starting the procedure.
- 🔋 Make sure your battery is at least 50% or connected to the network.
- 💾 Check the memory card for errors and free up at least 1 GB of space.
- 📱 Install the latest version of the application 70mai from Google Play or AppStore.
- 📶 Stabilize your internet connection on your smartphone if you plan to upgrade over Wi-Fi.
☑️ Preparations for renewal
It is not superfluous to back up important settings or video files if they have not been previously copied to the cloud. Although the upgrade process does not usually affect the user archive, reinsurance is never superfluous when working with electronics.
Automatic updates via 70mai app
The easiest and most common way is to use an official mobile app, a method that is suitable for most modern models equipped with a Wi-Fi module. To begin, open the 70mai app on your smartphone and make sure that the registrar is on and on standby.
Connect your smartphone to a Wi-Fi network that the DVR gives away. The password is usually indicated on a sticker on the device body or in the instructions. Once successfully paired, the application will automatically check for a new version of the software. If the update is available, you will see the corresponding notification on the home screen or in the settings section of the device.
Menu: Device profile → Settings (cogs) → Software updatePress the Update button and wait until the boot is finished, at which point the recorder may reboot several times, and the indicator may flash in different colors, interrupting the process at this stage is unacceptable.
What to do if the update button is inactive?
Once installed successfully, the new version will be confirmed by a voice message (if a voice packet is enabled) or a change in the version number in the interface.
Manual installation of firmware through a computer
In situations where automatic updates are not possible due to server errors or connectivity issues, the manual method requires a computer, a card reader and a memory card, which is considered more reliable for advanced users.
First, you need to download the current firmware file from the official manufacturer's website or a proven resource. It is important to download the file specifically for your model, since the firmware from the 70mai A200 will not work for the A400 and can bring the device down. The file usually has the.bin or.sig extension.
Copy the downloaded file into the root directory of the memory card. Don't put it in folders, otherwise the registrar can't find it. Then insert the memory card into the recorder off and turn the device on, and the system automatically detects the update file and prompts you to start the process.
| Model | File type | File name | Way |
|---|---|---|---|
| 70mai A500S | .bin | M500V1.0.0.bin | root of the map |
| 70mai A800S | .bin | A800V1.0.0.bin | root of the map |
| 70mai Lite | .bin | LiteV1.0.0.bin | root of the map |
| 70mai Pro Plus+ | .bin | PlusV1.0.0.bin | root of the map |
💡
The manual method allows you to bypass server limitations and update the device, even if the automatic method gives a boot error.
During manual firmware, the recorder screen (if any) may turn off or blink. This is normal behavior. Wait until the device sounds complete or restarts on its own.
Solving common problems and errors
Even if all instructions are followed, there can be unforeseen complications, such as the “Update failed” message or the endless download cycle, often due to a memory card that is not working properly or a firmware file that is damaged when downloaded.
If the update hangs on a certain percentage, try replacing the memory card with another, preferably from a well-known brand with a high speed class (Class 10 and above), and it is worth checking the integrity of the downloaded file by comparing its size with the one listed on the site.
- 🔄 Reset the Registrar settings to factory before trying the update again.
- 🔌 Use another power cable or power supply with sufficient current strength.
- 📱 Try to perform the procedure from another smartphone or through an access point.
In some cases, cleaning the 70mai app cache on your smartphone helps. To do this, go to Android settings, find the app and select Clear the cache. After that, restart the app and try to connect to the registrar again.
If neither method works, the problem may be hardware, such as overheating the processor during recording, so let the device cool down and repeat the procedure in a cooler room.
