- Fixed app store loading issue.

1. Put it on microSD

Copy the main firmware .bin into /OTA-Firmware-Update/. Keep only the intended update image there.

2. Start from Settings

Open Settings → Firmware Update → From SD Card. The updater verifies the image before changing boot state.

3. Let recovery finish

Keep battery power stable. The independent recovery image can restore the main partition if an update is interrupted.
