SMHUB OS - Update & Restore Methods

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

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

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

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 or you need a clean reinstall.

How:
Connect SMHUB to your PC → Download firmware → run flashing script (flash.bat) https://smlight.tech/support/manuals/books/smhub/page/updaterestore-using-type-c

✅ Shows progress on screen
✅ Quick and easy if drivers/cable are OK
⚠️ May fail if USB drivers aren’t installed or cable is poor
💡 If this fails - use SD-Card method below

💽 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
⚠️ No visible progress - just wait patiently
⚠️ Remove SD before next boot (otherwise it will flash again)
