Step 12

Be careful to not damage the battery during this step. If it appears you are using too much force to separate the battery from the frame, you may need to heat the phone to soften the adhesive holding the battery to the phone.
Starting at the bottom left corner of the battery, use the wide end of the spudger as a wedge to get underneath the battery.
Insert a plastic opening tool into the space created by the spudger and CAREFULLY begin to pry around the edge of the battery.
Once the battery is separated for enough from the phone, use your hands to fully remove the battery, using the wide end of the spudger to scrape off adhesive where necessary.

I want to clarify that in step 4 you don’t want to try to separate the back cover in the actual sim card slot but above it between the back cover and the top of the slot.
