Installation

The methods below are mutually exclusive, choose one that matches your setup and follow only those steps.

Tip

Regardless of which installation method you choose, you can pre-configure options before flashing by setting system properties on the device. For example, to enable a longer live setup timeout:

adb shell "setprop zip.google-sync-addon.LIVE_SETUP_TIMEOUT 8"

Via custom recovery

  1. Transfer the flashable zip to your device’s internal storage or microSD card.

  2. Reboot into recovery (hold Power + Volume Down β€” exact key combination depends on your device).

  3. In TWRP, tap Install, navigate to the zip file and select it.

  4. Swipe to confirm the flash.

  5. Follow the on-screen prompts for the live setup (e.g., choose which optional apps to install).

  6. Once the flashing is complete, tap Reboot β†’ System.

Via ADB sideload

  1. Reboot into recovery.

  2. In TWRP, tap Advanced β†’ ADB Sideload, then swipe to start.

  3. On your PC, run:

    adb sideload google-sync-addon-*.zip

  4. Follow the on-screen prompts for the live setup (e.g., choose which optional apps to install).

  5. Once the flashing is complete, reboot the device.

Via zip-install.sh (ADB or terminal, root required, no recovery needed)

This method installs the zip from a running Android system using zip-install.sh.

  1. Connect your device via USB with USB debugging enabled (ADB only β€” skip if using a terminal app on the device).

  2. Open a shell: run adb shell on the PC or open a terminal app directly on the device.

  3. Transfer the flashable zip to your device’s internal storage or microSD card.

  4. Run:

    cd <path/to/my_folder/>
unzip ./google-sync-addon-*.zip zip-install.sh
sh ./zip-install.sh ./google-sync-addon-*.zip

    The script will flash the zip directly on the running system, without using the recovery.

  5. Follow the on-screen prompts for the live setup (e.g., choose which optional apps to install).

  6. Once the flashing is complete, reboot the device.

Uninstallation

To uninstall re-flash the zip, enable live setup and select Uninstall.
