Conclusion
If possible, turn on your device and test your repair before installing new adhesive and resealing. Note: do not wear the earphone disassembled as the feedback loop / Larsen effect may kick in and produces a very loud sound.
To reassemble your device, follow these instructions in reverse order.
For optimal performance, '''***[[Battery Calibration|calibrate]] your newly installed battery'''***: Charge it to 100%, and keep charging it for at least two more hours. Then, use it until it shuts off due to low battery. Finally, charge it uninterrupted to 100%
Take your e-waste to an [[E-Waste|R2 or e-Stewards certified recycler|new_window=true]].
