Steps: 25 Steps
Ready to swap out your Samsung Galaxy S21+ USB-C charging port and daughterboard? Follow these steps and get your device powered up again! Heads up: keeping your phone water-resistant depends on how well you reapply the adhesive—after this repair, the official IP rating will take a little vacation.
Step 1
Oops! If you poked the SIM eject tool into the microphone hole by mistake, no big deal—chances are, the microphone is still perfectly fine.
- Grab a SIM eject tool, the tiniest bit you own, or even a straightened paper clip—whatever works! Find the SIM card tray hole on the top edge of your phone.
- Give that tool a gentle push into the hole until the SIM card tray pops out like magic.
- Slide out the SIM card tray and give yourself a high five. Nice work!
Step 2
Before you dive in, make sure your device is switched off. Let’s keep things safe and smooth!
A hair dryer, heat gun, or hot plate can come in handy, but keep it cool—literally. Avoid overheating the phone, since both the display and internal battery are pretty sensitive to heat damage. Use gentle, controlled heat and stay alert to prevent any mishaps.
- Warm up an iOpener and gently press it against the bottom edge of the back cover for about two minutes. This helps loosen the adhesive so you can get inside more easily. If you need help, you can always schedule a repair.
Step 3
If the back cover is doing its best impression of a spiderweb, the suction handle might not cooperate. Grab some heavy-duty tape to lift it, or glue the suction handle in place—just make sure to let it set before going any further.
If the gap’s playing hard to get, hit the adhesive with a bit more heat to make it loosen up. Keep an eye on the iOpener instructions so things don’t get too toasty.
- Stick your suction handle right at the bottom edge of the back cover—get it as close to the edge as you can.
- Give the suction handle a gentle lift to open up a tiny gap between the back cover and the frame.
- Slide an opening pick into that gap you just made. Keep it chill and steady.

Step 4
- Gently slide the opening pick down to the bottom left corner to cut through the adhesive. Go slow and steady, you've got this!
- Once the pick is in place, leave it there to stop that adhesive from trying to seal back up. No peeking until you're ready!
Step 5
- Pop a second pick in along the bottom edge—think of it as backup for your adhesive-busting adventure.
- Slide that pick over to the bottom right corner and slice through the sticky stuff like a pro.
- Let those picks chill in place so the adhesive doesn’t get any sneaky ideas about sealing itself up again.
Step 6
- Warm up an iOpener and gently press it against the right edge of the back cover for about two minutes to soften the adhesive.

Step 7
Sticky adhesive acting like it’s been to the gym and gotten all tough? Just warm it up again—pop a toasty iOpener back on the edge and watch it chill out so you can keep slicing like a pro.
- Start by slipping a third opening pick into the bottom right corner of your device.

- Grab a fifth opening pick and gently slide it underneath the bottom left corner to get things started.
- Then, glide that opening pick along the left edge of the back cover, carefully slicing through any remaining adhesive to free it up.
Step 12
- Start by removing the back cover of your device. During reassembly, it's a smart move to power on your phone and test all functions before sealing it up tight. Just make sure to power it down completely before continuing. Use tweezers or your fingers to carefully pick away any leftover adhesive chunks, and wipe away any residue with some high-concentration (over 90%) isopropyl alcohol. If you're using custom-cut adhesives, follow the specific guide for those, or if double-sided tape is your choice, refer to its guide. Need a hand?
