If you get locked out of your Android phone by the Pattern Lock you can restore your system to factory settings. However, this will erase all of the data on your phone. There may be some options to unlock the phone. But, in the case that you cannot unlock it this tutorial may be helpful. This will allow you to copy files from your Android device to a computer. This tutorial will focus on Windows users but similar instructions should work for OS X or Linux.
What you will need:
- USB driver for your phone (should not be necessary for OS X and Linux)
- The Android Debug Bridge utility (adb):
- Included in the Android Software Development Kit (Android SDK)
The first thing you will need to do is install the correct USB drivers for your system. Some OEM drivers may be downloaded from developer.android.com. If you can’t find a working OEM driver you may be able to find a generic one from hexamob.com.
Once the driver is installed you will need to connect your phone via USB and put it in Field Test Mode (FTM). To do this first turn your phone off. Now press and hold the “volume down” button and the “power” button. The phone will begin to boot and you will probably feel a small vibration. You should be able to release the buttons after you feel it. If you did it correctly the screen should display “FTM” once it has booted up. If it is the first time you have connected the phone in FTM mode it may take a moment for the computer to recognize it. Once it is recognized it should show up in the computer’s device manager. Mine is displayed as “Handset ADB Interface”.
Now that the computer is connected to the phone we can access its contents with the Android Debug Bridge utility. Extract “adb.exe” from the zip file containing the Android SDK. Open a command prompt. If you did not extract “adb.exe” to a directory found on the system path (such as C:\Windows) then you will need to navigate to the directory where it is located. Create a directory for the files to be extracted (example: mkdir pulled). Photos and images taken by the phone’s camera will likely be stored somewhere under the directory “/storage”. Execute the following command to copy the files from the Android device: adb pull /storage pulled. This will take everything that is found in “storage” and copy it to the “pulled” directory. If you want to pull EVERYTHING that you have access to, not just pictures and images, then execute “adb pull / pulled” (without quotes).
