# Enable app ROOT

Grant ROOT to specific app packages on 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**: pushes the package allow-list to the device and, as a side effect, turns the ROOT switch on. **Nothing is stored by MoreLogin**, so the grant cannot be read back through the API.
- **Completion**: synchronous acceptance by the service. When ROOT takes effect on the device is device-specific behaviour; MoreLogin does not restart the phone.
- **Note**: there is currently no endpoint to revoke ROOT for individual packages. Use `/cloudphone/enableRoot` to turn the global switch off.

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.
