Upgrade Android OTA File via ADB

This guide explains how to upgrade an Android-based SBC (Smart Control Panel) using an OTA (update.zip) file via ADB.

1. Connect the Android Device

You can choose one of the following methods to connect the device to your PC:

Option 1: Connect via USB

Connect your Android smart control panel or SBC to the PC using a USB data cable. Run the following command to confirm the connection:

adb devices

Option 2: Connect via WiFi

Ensure both the Android device and the PC are on the same network. Connect using:

adb connect <device-ip-address>
adb devices

Replace with the IP of the Android device.

2. Push OTA File to Device

After connection is successful, push the OTA update file (xxx_ota.zip) to the device:

adb push xxx_ota.zip /sdcard/update.zip

3. Start OTA Upgrade

Open an ADB shell:

adb shell

Then trigger the OTA upgrade via broadcast command:

am broadcast -a com.smatek.ota.download.complete --es com.smatek.ota.download.path /storage/emulated/0/update.zip

✅ Note: Replace the OTA path if you used a different location or filename.

Result

After the broadcast, the device should begin processing the update. You may observe a reboot or system update UI depending on your firmware integration.
