I dont know the screen lock pin for my huawei phone help?
If you know the Gmail address and password that was used to initialize the phone, you can use Google's Android Device Manager to erase and reset it. Without these credentials, you will have to use the phone's external softkeys to restore it to factory settings.
Google Android Device Manager
Google's Android Manager is able to find, lock and erase the Huawei smartphone through the use of locating features on most Huawei Android phones. Sign into the Web app using the Gmail address and password (link in Resources) and -- if there is more than one Android device registered to the account -- select the correct device name from the drop-down menu at the top. Click the "Erase" option once the phone has been located by Google. This won't work unless you've registered the phone with Android Manager in the past.
Without the Google Credentials
Without Google account access, however, you'll need to reset the device using its external buttons. This procedure varies based on model, but typically involves simultaneously holding down a combination of buttons until the device enters Recovery Mode. Huawei's Valiant and Vitria models, for example, both require you to push the "Volume Up" and the "Power" keys for several seconds until an Android robot with a red error sign appears on the screen. At this point, you can navigate the recovery meny using the "Volume Up," "Volume Down" and "Power" buttons, and select the option to erase the device.
