Step 1
– Before you start, make sure to power off your phone – it’s an important safety step.

If your screen’s looking like a spider web, don’t fret! Stick some packing tape over those cracks to give your suction cup a solid grip. Let’s get this repair rolling!
– Grab a suction cup and stick it to the back cover like a pro.
– Give it a gentle pull to create a little space between the back cover and the phone’s frame.
– Slide an opening pick into that newly created gap and get ready to continue the adventure!

Step 3
Don’t be afraid to give that adhesive a little extra love with some heat if it’s being stubborn. Just remember, heat is your friend—force is not! And hey, if you’re feeling overwhelmed, you can always schedule a repair with us.
– Hey, you’ve got this! There’s a bit more sticky stuff along the top and around the camera, so be careful.
– Alright, now carefully cut along the left edge near the fingerprint sensor. It’s super important to be gentle here to avoid messing with the ribbon cable inside.
Step 4
Be careful not to shove the pick more than halfway into the phone while you’re working near the fingerprint sensor or cameras. You wouldn’t want to accidentally poke something important inside!
– Let’s get started by cutting the adhesive on the right side, working from the center out. Use an opening pick to carefully cut up and down the right side.
Step 5
Heads up! This corner is a bit fragile, so be extra careful. If the adhesive starts acting up, just crank up the heat a bit. You got this!
– Place an opening pick snugly in the upper-right corner to get things started.
– Grab another opening pick and carefully slice through the adhesive at the bottom-right corner.
– Keep that trusty opening pick in the phone for now; it’s doing a great job!
Step 6
– Ready to loosen up that adhesive? Let’s warm up the left side of the rear panel. Grab a heat gun or hairdryer (or maybe even a heated iOpener, those are cool, too) and give it a good three minutes of heat. This will make the adhesive underneath nice and malleable, making things a whole lot easier to work with.

Step 7
Watch out for those corners! The glass can be a bit fragile there.
Don’t get too wild with the opening pick on the left edge near the fingerprint sensor. You could accidentally damage the ribbon cable inside. If you need help, you can always schedule a repair
It’s totally cool if those opening picks decide to take a tumble as the back cover pops off. No worries!
– Let’s get started by inserting an opening pick into the lower-left corner of the rear panel – easy does it!
– Now, grab another opening pick and carefully cut the adhesive along the left edge of the rear panel. If you need help, you can always schedule a repair
Step 8
Grab your trusty iOpener, a hair dryer, or a heat gun and warm things up a bit where you’re slicing through that pesky adhesive. A little extra heat can go a long way!
– Now, with your trusty opening pick, let’s carefully cut through that sticky stuff around the top left corner of the back panel. You’ve got this!
– Time to finish up! Give that adhesive along the top of your phone a final snip. Almost there!

Step 9
Hold your horses! Don’t yank out that fingerprint sensor ribbon cable just yet.
The fingerprint sensor cover may still be cozying up to the midframe.
– First things first, let’s tackle that right side of the rear cover! Give it a gentle separation.
– Now, give the cover a little tilt upwards along the left edge so you can sneak a peek at the fingerprint sensor ribbon cable.
Step 10
– Now it’s time to carefully pry the fingerprint sensor ribbon cable out of its socket – use the tip of a spudger to gently lift it up and out. If you need help, you can always schedule a repair

Step 11
– Time to get that back cover off! Start by removing it carefully.
– Now, let’s get that back cover back on:
– Grab some tweezers and gently peel away any leftover adhesive that’s still clinging to your phone’s chassis. After that, give those adhesion areas a good clean with high concentration isopropyl alcohol (at least 90%) and a lint-free cloth to get everything ready for the new adhesive. No need to get every speck of adhesive off—just make sure to remove the bigger chunks.
– Before sealing everything up, power on your phone and give your repair a test run. Better to check now than later!
– Finally, apply the new adhesive to the back cover with care. Line up one edge of the glass with the phone chassis and press it firmly into place. You’ve got this!
Step 12
– Grab your heat gun, hair dryer, or a heated iOpener and give that fingerprint sensor a warm hug from the outside. We’re aiming to soften that pesky adhesive hiding underneath. Keep heating it up until it’s just a tad too warm to touch; we want it cozy enough for the adhesive to loosen up without putting up a fight.

Step 13
– Slide an opening pick beneath the back of the fingerprint sensor.
– Gently twist the pick to pop the fingerprint sensor away from the back cover.
Step 14
To get that fingerprint sensor up and running again, grab a pre-cut adhesive sheet and use it to replace the old adhesive – easy peasy! If you need help, you can always schedule a repair
– Time to ditch that old fingerprint sensor – carefully remove it from your device.
– Now, let’s get that new fingerprint sensor installed:
– Grab your trusty tweezers and gently peel off as much of the adhesive as you can. Next, use 90% isopropyl alcohol and a lint-free cloth to wipe away any remaining sticky stuff. If you need help, you can always schedule a repair
