Before disassembling the phone, remove the SIM card and the MICRO-SD card, if equipped.

Begin taking apart the device by prying apart the back cover from the assembly using the plastic opening tool.

Continue working around the edge of the phone using the plastic opening tool.

When all the edges have been lifted apart, use your hands or plastic opening tool to peel the back plate from the battery. There are small adhesive strips between the back cover and the battery, so take care not to crack the back cover while prying open.
