# @ohos.enterprise.deviceControl (Device Control)

The **deviceControl** module provides APIs for device control, which can be called only by device administrator applications.

> **NOTE**
> 
> - The initial APIs of this module are supported since API version 10. Newly added APIs will be marked with a superscript to indicate their earliest API version.
> - The APIs of this module can be called only after a [device administrator application](js-apis-enterprise-adminManager.md#adminmanagerenableadmin) is enabled.

## Modules to Import

```js
import deviceControl from '@ohos.enterprise.deviceControl'
```

## deviceControl.resetFactory

resetFactory(admin: Want, callback: AsyncCallback\<void>): void

| admin | [Want](js-apis-app-ability-want.md) | Yes   | Device administrator application used to restore the factory settings.|
| callback | AsyncCallback\<void> | Yes| Callback invoked to return the result. If the operation is successful, **err** is **null**. Otherwise, **err** is an error object.|

**Error codes**

For details about the error codes, see [Enterprise Device Management Error Codes](../errorcodes/errorcode-enterpriseDeviceManager.md).

| ID| Error Message                                                                     |

**Example**

```js
let wantTemp = {
    bundleName: "bundleName",
    abilityName: "abilityName",
};
deviceControl.resetFactory(wantTemp, (error) => {
    if (error) {
        console.log("error code:" + error.code + " error message:" + error.message);
    }
})
```

## deviceControl.resetFactory

resetFactory(admin: Want): Promise\<void>

Restores factory settings. This API uses a promise to return the result.

**Required permissions**: ohos.permission.ENTERPRISE_RESET_DEVICE

**System capability**: SystemCapability.Customization.EnterpriseDeviceManager

**System API**: This is a system API.

**Parameters**

| Name  | Type                                 | Mandatory  | Description     |

| Type  | Description                                 |
| ----- | ----------------------------------- |
| Promise\<void> | Promise that returns no value. If the operation fails, an error object is thrown.|
