How to update the firmware on the video recorder Xiaomi: the full guide

Modern car gadgets require constant attention to software, and DVRs Xiaomi or 70mai are no exception.Developers regularly release patches that fix bugs, improve recording stability and add new features such as road sign recognition or improved night mode. Ignoring these updates can lead to malfunctioning of the device at a critical moment.

The process of updating firmware can seem complicated only at first glance. There are two main methods: automatic via a smartphone and manual through a memory card, the choice of method depends on the model of your device and the current situation with the Internet connection.

In this article, we will discuss both methods in detail, paying special attention to precautions that will help to avoid turning the registrar into a “brick”, you will learn how to properly prepare the medium and what to do if the process goes wrong.

Why You Need to Update Registrar Software

Many users mistakenly believe that if a device works properly, it is not worth touching its settings and software, but video processing algorithms are constantly improving. New versions of the firmware often include optimization of the camera sensor, which directly affects the readability of car numbers in difficult weather conditions.

In addition, updates often close vulnerabilities in Wi-Fi protocols, because the recorder creates an access point to transmit video to the phone, the security of this channel is critical. Outdated software can contain holes through which attackers can theoretically access data.

⚠️ Note: Installing beta versions of the firmware for testers can cause unstable operation of the device. Use only stable releases from the official website or from the application.

Also worth mentioning is compatibility with new versions of mobile applications Mi Home or 70mai. Sometimes after updating the application on the smartphone, the old registrar stops synchronizing correctly, and the only solution is to upgrade the internal system of the gadget itself.

Preparation for the procedure: Version verification and backup

Before you start any manipulation, you need to know the current version of the software, this is necessary to understand whether it is relevant, and in case of problems, you can return to the original state or report accurate data in support.

To check, go to the app, connect to the registrar, and go to the settings menu. Usually, the path is: Settings → About device → Software version. Write down these numbers or take a screenshot.

The next critical step is to save important records, and although the update process doesn't usually affect user files on the memory card, there's always a risk of damage to the file system.

Also make sure that the device battery (if built-in) is at least 50% charged, or connect the recorder to an external power source during the upgrade.

• 📱 Charge your smartphone to a minimum 40-50% stable operation of the Wi-Fi module.
• 💾 Make room on the memory card (it is desirable to have at least one). 10-15% free-space).
• 📶 Make sure the internet connection on your phone is stable (for example, OTA-update).
• 🚗 Carry out the procedure in a parked car with a silenced engine to avoid interference.

Method 1: Update via Mobile Application (OTA)

The easiest and most common way to do this is to use the official Mi Home or 70mai app, which is called OTA (Over-The-Air), and allows you to upgrade your device without having to remove memory cards or use your computer.

Launch the app and connect to the DVR. If the new version of the software is available, a notification will appear on the home screen or in the settings section, and the system will check the compatibility of your model and the regional version of the device.

Once you click the Update button, the data packet will start loading, and the speed depends on the version of Bluetooth and Wi-Fi modules in your registrar, and during this process, stay in the app and hold your phone next to the device.

⚠️ Warning: Do not attempt to play video or change the registrar settings during download and installation of the update.

When the download is complete, the installation phase will begin, the recorder will restart, and the indicators will flash at a certain rhythm, which can take from 3 to 10 minutes, and after successful installation, the device will sound an audible signal or a voice message.

Method 2: Manual installation of firmware through SD-map

If the automatic update doesn't work or you want to install a specific version of the software, you'll have to use the manual method. It requires a computer and a card reader. First, find the official firmware for your model on the 4PDA forum or manufacturer's website.

A firmware file usually has a.bin or.miu extension. It needs to be placed in the root of the memory card. Importantly, the card needs to be formatted in the FAT32 file system. Using exFAT or NTFS can result in the registrar simply not seeing the file.

Put the memory card in the recorder off. Connect the device to power. It will automatically detect the update file and prompt you to start the process (or start it automatically, depending on the model).

Once the process is complete, the registrar will overwrite the system partition and restart the firmware file on the memory card, which can be automatically renamed or deleted, indicating the successful completion of the operation.

Compatibility table and (Frequent problems)

Not all models support the same upgrade methods, and users often have similar difficulties. Below is a table that will help you navigate the main features and solutions.

The Chinese firmware versions (CN Version) may differ from the global versions, and installing Chinese firmware on a global device (and vice versa) can lead to loss of functionality, such as voice control or changing the interface language.

If the device is acting strangely (heating, often turning off) after the upgrade, try a full Factory Reset, which will return all parameters to factory values, eliminating possible conflicts of old settings with new software.

Diagnosis and recovery after a failed update

In rare cases, the process may not work properly. If the recorder has stopped turning on or only the red indicator is on, don't rush to throw the device away. Often, a "hard" reboot helps.

Try to pinch the reset button (usually a small Reset hole) for 10-15 seconds when power is connected. If that doesn't work, you'll need to flash it again through the memory card, possibly using an older, stable version of the recovery software.

💡

Use high-quality Class 10 and higher memory cards from well-known brands (Samsung, SanDisk, Kingston). Cheap cards are the main cause of write errors and failures when updating firmware.

Some models have a Recovery Mode, which requires a certain combination of buttons (e.g., OK and Power) to enter before power is connected, and in this mode, the device can accept firmware even when the main system is damaged.

💡

Regular firmware updates are not just a whim, but a necessity for data security and record quality. Always check the status of the software at least once every six months.
