# Enable or disable global ROOT

Turn the global ROOT switch on or off for a Cloud Phone.
- **Preconditions**: the phone must be powered on and not held by another member. Supported on compatible device models; on incompatible models the call succeeds but has no effect.
- **Effect**: unlike `/cloudphone/app/openRoot`, the setting **is persisted** on the phone's settings record and then pushed to the service as a device-wide switch.
- **Completion**: synchronous. MoreLogin does not restart the phone; when the change takes effect on the device is device-specific behaviour.
- **Retry**: idempotent.

Documented business errors: `33300`, `33301`. See [Error Codes](../Getting%20Started/error-codes.md) for what each code means. Any operation can additionally return the common codes.
