Introdução
If you have determined that faulty speakers are the cause of distorted audio, follow this guide to replace them. If you are unsure, follow these steps in the Troubleshooting Page to determine if the issue is caused by your headphones, the audio jack, or the speakers themselves. Removing the speakers is also necessary before replacing the battery.

Conclusão
To reassemble your device, follow these instructions in reverse order.
