In the following steps you will be releasing the clips holding the phone's cases together. However, the back case is also secured with an adhesive pad. After separating the clips you will use an iOpener to allow the case to fully open. Do not attempt to fully open the phone before loosening the adhesive.
Insert a plastic opening tool into the seam between the front and rear covers near the SIM card slot.
Slide the plastic opening tool along the seam toward the upper corner.
Run the opening tool along the seam around all four sides, separating the remaining clips holding the cover on.
The plastic on the front cover is thinner near the buttons, and the buttons may move around. Go slowly to avoid damaging the buttons or the front cover.
Do not push the opening tool deep into phone, or you may damage internal components.
Starting from the SIM slot side, carefully peel the back cover off of the phone.
The back cover is very flexible, but you don't want to damage any internal components by being too hasty.
There is a chance that the NFC coil may remain stubbornly adhered to the back cover. If that's the case, stop peeling the cover and reapply a heated iOpener to the back cover.
Do not separate the back cover entirely; it is still connected to the phone by the camera flash cable.
The flash cable is attached on the power/volume button side of the phone.
I was able to follow this guide, but the T3 Torx was too small. The T4 Torx was also too small. Fortunately I had a T5 Torx which worked perfectly. During removal of the back I damaged my NFC antenna and can't use my Moto Skip anymore. Be careful with that component.
NO seriously I have done a ton of electronics projects and getting a torx screwdriver that actually works with most electronics has been a struggle this is the new version of the husky 8-1 I have the old version I believe they are the same. This thing has caught thread on screws where I had given up hope
This is insane. I'm a computer tech, I build computers for a living. I repair components. Fixing this little crappy phone is crazy complex. Look at all the comments saying "be careful of x because I destroyed it accidentally". Not a one says "wow, that was incredibly simple".
I personally wouldn't try it -- I'd just get another phone and have it swapped onto my account. And then I'd stop doing whatever I'd done to break the first one.
