Step-by-Step Process
Step 1:
For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.

Unplug any chargers/peripheries and power off your phone.
Step 2:
If the rear glass is cracked, be sure to [guide|140533|tape over the glass panel|new_window=true] before moving on.
Step 3:
Use a hair dryer to lightly heat the perimeter of the rear glass.
Additionally, heat the top-right corner, as there is adhesive further inside of phone in that one spot.
Do not hold the hair dryer in one spot on the phone for too long to prevent damage to internal parts of the phone.
Step 4:
Apply a suction handle as close to the bottom edge as possible.
Pull up on the suction handle with strong, steady force to create a gap between the glass and the frame.
If you have trouble creating a gap, apply more heat to further soften the adhesive.
Insert an opening pick into the gap.
Step 5:
Slide the opening pick around the perimeter of the rear glass to slice the adhesive.
Insert additional opening picks as you slice the adhesive to prevent the adhesive from resealing.
If the adhesive becomes hard to cut, it has most likely cooled down. Use your hair dryer to reheat it.
Step 6:
Carefully lift the rear glass up and off of the phone.
During reassembly [guide|113604|secure the rear glass with pre-cut adhesive|new_window=true] or double-sided adhesive tape. After installing the rear glass, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.
Step 7:
Use an opening pick or tweezers to carefully peel back the adhesive on the bottom of the wireless charging module.
Step 8:
Pry on the bottom of the flash module off using a pick and use tweezers to get under the module without ripping it.
Be careful unplugging the module as the cable is very delicate.
Step 9:
Use a Phillips #000 screwdriver to remove the eleven 4.8 mm-long screws securing the motherboard cover.
Step 10:
Pry around the phone with picks to remove the motherboard cover.
Step 11:
Lift off the motherboard cover.
Step 12:
Pry up and disconnect the press connector ribbon cable in the top right with a spudger.
Make sure not to damage them in the process.
Step 13:
Use a spudger to disconnect the two interconnect cables from the motherboard by prying the connector straight up from its socket.
Step 14:
Take care not to bend or puncture battery during the removal procedure—a bent battery may leak dangerous chemicals or cause a fire.
Remove the battery from the phone by slowly pulling up on the red tabs.
If you're having trouble lifting the battery out of its recess, apply a heated iOpener to the screen side for two minutes to loosen the battery adhesive.
A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the device.
