Step 5

Insert the spudger between the midframe and the display assembly.
Gently pry up the midframe.
When working with electronics, it's important to choose a tool that's ESD-safe to avoid accidental damage to the device. The metal spudger is great when you need serious prying power, but the regular black nylon spudger or a plastic opening tool should be used whenever possible.

Step 6

Where the battery rested before, you will find a small clip that holds down the midframe.
After the rest of the midframe is detached, from the phone place the flat end of the spudger beneath the clip.
Gently lift up on the clip until it comes free.
Remove the midframe from the phone.
