How to Russify the DVR Xiaomi 70mai 1S: 4 working methods

The Xiaomi 70mai 1S DVR is a popular device among Russian drivers due to its combination of price, quality and functionality. However, many users face a problem: the default registrar comes with Chinese or English firmware, where Russian is either missing or works with errors, a problem that is especially relevant for devices purchased on foreign sites like AliExpress or Gearbest, where sellers do not adapt firmware to local markets.

In this article, we will discuss all the current ways to Russify the 70mai 1S, including official updates from Xiaomi, manual language change through menus, custom firmware installation and alternative methods. Each method has been tested on models 2020-2023 and is suitable for firmware versions 3.1.0 and later. If your registrar is released before 2020, some instructions may not work due to hardware limitations, in which case we recommend you refer to the section with alternative solutions.

1. Check the current version of firmware and language

Before you start Russification, you need to make sure that your 70mai 1S supports Russian at all. In some batches of devices (especially 2019-2020), Russian localization is absent at the iron level, and it can only be added through informal firmware.

To check the current settings:

1. Turn on the recorder and wait for the main screen to load.
2. Touch the icon "Settings" (cog in the upper right corner).
3. Go to System → About (or System → About if the menu is already partially Russified).
4. Pay attention to the Firmware Version (firmware version) and Language (current language) fields.

If the list of available languages (Settings → Language) does not include Russian, but the firmware version is older than 3.0.5, you can try to update officially. If the firmware is outdated (for example, 2.9.x), you will need to manually install the new version.

2.Official method: Update firmware through the 70mai application

The safest and most recommended method is to upgrade through the proprietary 70mai app (available for Android and iOS), which is suitable if:

• 📱 You have a smartphone with Bluetooth 4.0 support+;
• 🔋 Registrar charged at least 50 times%;
• 🌐 Access to a stable Internet connection (Wi-Fi or mobile network).

Step-by-step:

1. Download and install the 70mai app from Google Play or the App Store.
2. Connect the Registrar to your smartphone via Wi-Fi: On the Registrar: Settings → Wi-Fi → Enable access point; On the phone: connect to the network 70mai_XXXX (password 12345678).

"Update firmware."

Do not turn off the registrar power during the process!

After updating, check for Russian in Settings → Language. If it is not available, proceed to the next method.

💡

If the application does not find updates, try to change the region in the smartphone settings to "Russia" or "China" and restart the application.

3. Manual firmware update via MicroSD

If the official update didn’t help or isn’t available, you can install the firmware manually, which requires more action, but is guaranteed to add Russian if you choose the right version of the software.

You'll need:

• 💾 MicroSD card (up to 32 GB, formatted in the form of a microSD card) FAT32);
• 🖥️ Computer with Internet access;
• 🔗 Firmware for 70mai 1S Russian language (see table below).

Download the current firmware with Russian from verified sources:

Installation instructions:

1. Turn on the registrar – it will automatically detect the firmware file and prompt you to update.
2. Confirm the installation with the “OK” button and wait for the reboot (about 3-5 minutes).

4. Alternative methods of Russification

If neither the official nor manual updates helped, there are two options left:

1. Install custom firmware (for example, from the 4PDA community);
2. Use of a menu interpreter (temporary solution).

Castom firmware is created by enthusiasts and may contain bugs, but often add support for the Russian language even on older models.

• 🛠️ ProshiVka_RU — Russification + supplementary;
• 🔧 70mai-Mods — Firmware with patches for different regions.

⚠️ Warning: Installing unofficial software can lead to loss of warranty and unstable operation of the device. Before firmware, back up important records from the registrar.

Temporary solution – use of the menu interpreter:

• 📱 Install the Google Translate app on your smartphone;
• 📸 Take a picture of the registrar screen through the camera translation function»;
• 🔤 Point the camera at the text of the menu – the application will show the translation in real time.

💡

Custom firmware can add not only Russian, but also new features: improved stabilization, night mode or support for memory cards up to 256 GB. However, the risk of "bricking" the device is higher than with the official update.

5. Frequent errors and their solutions

When Russifying the 70mai 1S, users often face typical problems.

⚠️ Warning: If after a failed firmware, the registrar stopped turning on (black screen, no button response), try a hardware reset:

1. Turn off the registrar from power;
2. Press the “REC” button (record) and, without releasing it, connect the charging;
3. Hold the button for 10-15 seconds until the 70mai logo appears.

6. How to save the Russian language after resetting settings

If you reset the registrar to the factory settings (Settings → Reset), the language may change back to English or Chinese.

1. Before reset, check the current firmware version in Settings → About the device;
2. If the firmware is Russified (for example, 3.5.0_RU), After the reset, the Russian language will remain on the list;
3. If the firmware is not Russified, do not reset - it will return the original language.

If the reset has already occurred, repeat the Russification process (see section 2 or 3).

💡

To avoid accidental reset, disable the Auto Reset option in the settings (if it is in your firmware).
