Video recorder Xiaomi 70mai Dash Cam 1S It gained popularity due to its compact size, Full. HD-It's easy to shoot and manage it through a mobile app, but many users have one problem: the default device comes with Chinese or English firmware, which makes it difficult to set up. In this article, we will analyze all the current ways of Russification of the registrar - from official updates to alternative methods using third-party software.

It is important to understand that the Russification process depends on the firmware version of your device. Some 70mai Dash Cam 1S models (especially those released before 2022) may require manual language pack installation, while new batches often support multi-channel interface out of the box. We tested all methods on firmware v3.8, v4.1 and v5.2 — the results are summarized in the comparison table below.

If you have never updated the registrar firmware, start with the official method. It is the most secure and does not require technical skills. Alternative methods (through ADB or modified files) are suitable for experienced users who are ready for possible risks. Devices with serial numbers starting with "DM1S21xx" are Russified only through the 70mai application - this is a manufacturer's restriction.

1. Official Russification through appendix 70mai

The easiest and most recommended way is to use the proprietary 70mai app (available for Android and iOS), the manufacturer regularly updates the language packages, and Russian is included in the standard configuration of the latest firmware.

1. Install the 70mai app from Google Play or the App Store.

2. Connect the registrar to the Wi-Fi network (click Menu → Wi-Fi → Enable the access point on the device).

3. In the app, select Add Device → Dash Recorder → 70mai Dash Cam 1S.

After synchronization, go to Settings → Language and select Russian. If you don't have an option, then your firmware is outdated - update it through the same menu section. Note: when you update through the application, all settings are reset to factory ones, so save important files from the memory card in advance.

• ✅ Pros of the method: safe, does not require a PC, retains the guarantee.
• ❌ Cons: It only works on newer firmware v4.0.
• ⚠️ Limitation: Some batches of devices (e.g., with AliExpress) may have a blocked region.

2. Russification through a memory card (for firmware v3.8–v4.2)

If your registrar does not support Russian through the app, try installing the language package manually.This method works for v3.8–v4.2 firmware and requires a memory card up to 32 GB (formatted in FAT32).

• 📁 Firmware file with Russian language (you can download on the official website or forums like 4PDA).
• 💻 Computer with card reader.
• ⚡ Charger (update process takes place) ~10 minutes).

Instructions:

1. Download the archive with firmware (for example, DM1S_RU_v4.1.zip) and unpack it.
2. Copy update.bin to the root directory of the memory card (not to folders!).
3. Plug the card into the recorder and plug it into the power, and the device automatically detects the file and starts updating.
4. Wait for the reboot (the indicator will flash green) and check the language in the menu.

Critical moments:

• 🚨 Do not remove the memory card during the upgrade – this will lead to a knock (inoperability) of the device.
• 🔄 If the language has not changed after the update, repeat the procedure with the file. recovery.bin (It is present in some archives).

Alternative method: use of ADB (for advanced users)

If the standard methods didn’t work, you can try changing language settings via Android Debug Bridge (ADB), a method that is suitable for Android-based firmware (e.g. modified versions) and requires command line skills.

You'll need:

• 🖥️ Computer with drivers installed ADB (download).
• 🔌 USB-cable (preferably original).
• 📱 Enabled debugging mode on the registrar (activated via Settings) → The phone. → Assembly number (press 7 times)).

Command sequence:

adb devices # Checking the connection


adb shell # Entrance to the shell




setprop persist.sys.language ru




setprop persist.sys.country RU




reboot

⚠️ Attention: Misuse of the right ADB If the registrar does not turn on after the reboot, reset via adb reboot recovery (if supported).

💡

Before working with ADB, back up your current firmware with the adb backup -apk -shared -all -f backup.ab command. This will help restore the device in case of an error.

4. Problems after Russification and their solution

Even after a successful language change, users may face some problems, including the most common ones and ways to fix them:

• ⏱️ Dates and time are lost: Go to Settings → Date and time and select the 24-hour format. Time zone set manually (automation often works incorrectly).
• 📱 The app doesn't see the registrar: Remove the device from the list in the app, reboot the registrar and re-pair the pairing. If it doesn't, reset the settings through Settings. → Reset.

If after Russification, artifacts appeared on the menu (hieroglyphs instead of letters), then the language package is not fully installed.

2. Repeat the update procedure through the memory card.
3. If the problem persists, go back to the English version of the firmware and wait for the official update.
