What does Team ID 4 mean and how do I recover the RCK?
Team ID 4 is SkyCoach's default, unconfigured state. A crashed or reset RCK reverts to it.
The fix is Delete storage — NOT "Clear cache", and NOT "Restore app" (neither of those fixes it):
- Fully close the SkyCoach app.
- Long-press the SkyCoach app icon → App Info → Storage → Delete storage.
- Reopen the app. You should get a login screen.
- Log in while on a WiFi network with real internet (a phone hotspot is fine) and with the ethernet cable unplugged.
- After login: turn WiFi off, plug ethernet back in.
If no login screen appears you can either provide a QR code to login the RCK or install the latest version from the internet.
