Problem:

After being powered on, the phone automatically enters Recovery mode. In addition, the Reset phone icon is grayed out and can't be touched.

Solution:

You can Reset phone in Recovery mode by following the steps below:

Resetting your phone may cause all of the data on it to be erased, so please exercise caution when performing this operation.

1. Make sure that your phone is powered off and not connected to a USB cable.
2. Press and hold down on the Power and Volume up buttons until Recovery mode displays, as shown in the following figure (if there is no Volume button on your phone, press the Power button five times in succession to enter Recovery mode after the phone vibrates during a power-on).
3. Select Clear data > Reset phone (some phones may require you to enter "yes" to confirm the operation).
4. After resetting your phone, touch Back to return to the Recovery mode screen, and touch Restart to access the home screen.

   

If the issue remains unresolved, back up your data and take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance.
