Automatic method It is convenient because it does not require user intervention, but it does require a stable router signal. Manual method This is necessary in cases where the device has lost connection with the server or requires a rollback to a previous version after an unsuccessful experiment. It's important to understand that interrupting data recording can lead to a software failure.
In this guide, we'll cover both options in detail, as well as address common issues users encounter. You'll learn how to properly prepare your device for the procedure, where to find the latest firmware files, and what to do if the indicator lights are flashing abnormally. Technical support These steps are often referenced when diagnosing problems, so knowing this information will save you time.
Preparing your device for a system update
Before performing any manipulation of the software code, ensure that the battery is charged to at least 60%. If the charge is lower, the system may block the installation process to prevent complete discharge and memory corruption. It is recommended to place the cleaning robot on the charging station 30 minutes before starting the procedure, even if the indicator shows full charge, to equalize the cell voltage.
It is also critical to check the stability of your home network connection. Wi-FiThe device should be located in a strong signal area, ideally no more than 3-4 meters from the router, with no physical obstructions. Concrete or metal walls can significantly weaken the signal, resulting in connection timeouts while downloading data.
- 🔋 Charge the battery to above 60% for safe recording.
- 📶 Make sure the Wi-Fi signal at the installation location is stable and strong.
- 📱 Close the app on your smartphone to avoid synchronization conflicts.
- 🧹 Clean the sensors and wheels from dust before starting the procedure.
⚠️ Caution: Do not attempt to update if the robot is in cleaning mode or has just completed a cycle. Allow the electronics to cool and enter standby mode.
Ignoring the preparatory stage often results in errors that users perceive as hardware failure. In reality, firmware It simply can't write new files correctly if the power supply is unstable or the connection is intermittent. If you plan to update via USB, prepare a short, well-insulated cable in advance.
☑️ Ready for flashing
Automatic updates via mobile app
The most common and safest way to update is to use the official smartphone app. When developers release a new version, a notification usually arrives automatically. Open the control interface, go to the device settings, and find the section for the software version.
If a new version is available, the system will prompt you to download and install it. At this point robot cleaner The device will enter a special mode, locking the control buttons on the device. The smartphone screen will display a progress bar indicating the percentage of the operation completed. The entire process can take 5 to 15 minutes, depending on the package size and your internet connection speed.
- 📲 Open the app and select your device from the list.
- ⚙️ Go to the settings menu (usually a gear icon).
- 🔄 Click on "Software Update" or "Firmware Update".
- ✅ Confirm the action and wait for the installation to complete.
It's important not to close the app or move far from the router during the process. Although data transfer occurs via the cloud, a disconnection between your phone and the server may interrupt the file integrity check. After successful installation, your device will automatically reboot, and you'll hear a distinctive beep or voice message indicating completion.
Manual firmware installation via USB cable
Situations vary, and sometimes the wireless method doesn't work due to server errors or network issues. In such cases, manual installation via a wired connection. To do this, you'll need to find the latest firmware file on the manufacturer's official website or on trusted forums specializing in smart devices.
Unzip the downloaded archive onto your computer. Next, connect the robotic cleaner to your PC or laptop using a USB cable. Some models require you to press a special key combination while connecting to force the device to enter bootloader mode (Download Mode). The computer should detect the new hardware.
Path to firmware file: /Fujida/Karma_Bliss/Firmware/latest_v2.4.binOnce connected, use a dedicated firmware update utility, if provided by the manufacturer, or follow the instructions to copy the file to the root directory of the internal memory. After copying the file, disconnect the device and perform a factory reset. Upon boot, the system will detect the new file and initiate the update process automatically.
⚠️ Warning: Using firmware from unverified sources may cause irreversible damage to the controller. Always verify the checksums of the files.
What should I do if my computer doesn't see my device?
If your computer doesn't make a connection sound or display the new device when you connect a USB cable, try replacing the cable. Often, the problem lies with cables that are designed only for charging and don't have data lines. Also, check Device Manager for any unknown devices with a yellow exclamation mark.
Troubleshooting common upgrade errors
Even if you follow all the instructions, glitches may still occur. One of the most common issues is freezing at a certain percentage of the download. This may indicate a full app cache or a version conflict. In this case, it is recommended to completely uninstall the app, clear the smartphone's system cache, and reinstall it.
Another common error is the "Not enough space" message. Although the built-in memory is large, temporary logo files can take up a significant amount of space. Performing a full factory reset before trying again often resolves this issue. Reset deletes all user data, so the room map will have to be recreated.
| Error code | Description of the problem | Solution method |
|---|---|---|
| Error 101 | No connection to the server | Check your router's DNS settings |
| Error 204 | The file is corrupted | Redownload the firmware again |
| Error 305 | Low battery | Charge up to 80% |
| Error 404 | Server not found | Check the date and time on your device |
If the error persists after all attempts, the problem may lie in the flash memory hardware. In rare cases, reflashing the firmware via the debug port is required, which requires disassembling the case and using a programmer. This is a complex procedure that requires a qualified engineer.
Factory reset and reset
Sometimes a new version of software contains bugs that interfere with normal operation, or the user simply wants to restore the original state. There is a procedure for this. Hard Reset. On the body of most models Fujida There is a hidden hole with a reset button or a key combination that needs to be held for 10-15 seconds.
After resetting, your device will return to its out-of-the-box state. This means you'll have to reconnect to Wi-Fi, log in to your account, and set up a schedule. However, this ensures that any conflicting configuration files that may have accumulated over time are removed.
