SMHUB OS - Update & Restore Methods

Your SMHUB can be updated or restored in three different ways:

1. OTA (recommended) – simple updates directly from the Web Interface

2. Type-C Cable – full recovery if the device doesn’t boot via computer

3. SD-Card – full recovery if the device doesn’t boot without copmuter (more reliable)

Below is a quick overview to help you choose the right method 👇

🟢 1. Regular Update — OTA (Over-the-Air)

The easiest and safest method for normal updates.

How:
Web Interface → Settings → Updates & Restore → Check for Updates

What happens:
SMHUB downloads and installs the newest version automatically.

✅ Simple — no cables, no drivers
✅ Keeps your data and settings
⚠️ Works only if your system boots normally

⚡ 2. Restore via Type-C Cable

Good when OTA fails, if you need a clean reinstall, or if you want a quick setup without dealing with command-line environments.

How: Connect SMHUB to your PC via Type-C → Download and run the standalone smhub-flasher → Click to flash.

✅ Zero Configuration: No terminal commands or manual environment setups required.
✅ Always Up-to-Date: The interface automatically fetches and downloads the latest online images directly.
✅ Visual Feedback: Shows real-time progress right on your PC screen.
⚠️ Connection Requirements: Ensure you use a high-quality data cable and that your system detects the USB device.
💡 Alternative: If this fails or you prefer a different route, check the SD-Card method below.

⚠️ IMPORTANT: If the flashing process does not start, please disconnect POE and other Add-ons (4G/Z-Wave).

💽 3. Restore via SD-Card (Full Recovery Method)

Use this if your SMHUB is “bricked” or not responding at all.

How:
Copy 3 files (emmc.img, fip.bin, partition_gpt.xml) to a FAT32 SD card → insert into SMHUB → power on → wait ~5 min → power off → remove card → power on again

✅ Works even if device doesn’t boot
✅ No drivers, no software, no cables
✅ Visible progress - just wait patiently
⚠️ Remove SD before next boot (otherwise it will flash again)

IMPORTANT: If the flashing process does not start, please disconnect POE and other Add-ons (4G/Z-Wave)

🧭 Which method should I use?

In short:
🔹 Use OTA for normal updates.
🔹 Use Type-C if you need to reinstall.
🔹 Use SD-Card to fully recover a non-booting device.
