[EMUI Tips & Tricks] S-Susan:
When you click the title above and start to read this article, I guess you may have run into a trouble: Your smart device cannot be powered on? You have to recover the software system after a failed ROM flashing? You want to switch from a third-party system back to Huawei system after a successful ROM flashing?

Don't worry. Huawei provides you with eRecovery that excels at recovering the software system easily and successfully. If you fail to start your device because of a software fault, try eRecovery.

If your device system works, you are not advised to use eRecovery to update the system. At present, eRecovery is only available for some regions and models, and will be available for other regions and device models after some time. Please wait for your surprise.

*Note: It’s not supported for USA users and Docoma users in Japan.

Pay attention to the following points before system recovery:

1.	If you can enter the main system, please back up your data. All your personal data will be erased after your system recovered if you didn’t meet the following conditions when entered eRecovery system.

(1)	The data partition is mounted read-write mode. If the mounting fails and data clearing is required, a prompt will be displayed for you to know.

(2)	Your device is locked.

(3)	Your device has sufficient space in an internal or external card. If the space is insufficient, your device displays a message indicating that you need to empty the internal card or insert an external card.

2.	Ensure that a Wi-Fi hotspot is available (eRecovery supports some authentication modes, such as WPA-PSK, WPA2-PSK, WEP, and open system now).

3.	Keep connecting your device to power (A powered-on computer can also provide power).

Now, let's get back to the fixing:

1.	There are three ways to start eRecovery:

Method 1: The software system detects a startup failure, and your device automatically enters the eRecovery system;

Method 2: The software system automatically detects a fault (for example, your device uses a third-party system after ROM flashing), but the device can be started and displays a message on the UI. You can press and hold the volume up key for more than 3 seconds to enter the eRecovery system;

Method 3: You can initiate the process of entering the eRecovery system (by pressing and holding the volume up key for more than 5 seconds while your device is connected to power).

2.	Tap Download latest version and recovery on the UI to enter the download confirmation UI.

3.	Tap Download and recovery and waits for the software system to restart the Wi-Fi system and scan available hotspots.

4.	Select an available Wi-Fi hotspot and enter the password for connection.

5.	After your device is connected to the Wi-Fi hotspot successfully, the software system automatically obtains and downloads the upgrade package. You don't need to do anything at this stage. The package has a large size and may take some time.

6.	After the download is completed, your device automatically installs the upgrade package.

7.	After the upgrade is successful, your device automatically counts down and enters the software system. Voila! Your device works now.

After reading this article, you can recover your device no matter what happened to it before. If you think eRecovery is powerful, don't hesitate to share it with your friends.
