Duration: 30 min.
Steps: 24 Steps
Hey there! Just a heads up: once you pop open your device, the IP certification (that nifty shield against dust and water) will be on borrowed time. Keep that in mind as you dive into your repair adventure!
Get ready for a fun little adventure! In this easy-to-follow photo guide, we’ll walk you through the process of swapping out the USB board all by yourself, step by step. Let’s get to it!
Step 1
Before diving into the repair of your Galaxy S21 5G, take a moment to run through our handy checklist to test its basic functions. This little step will help you see if your repair efforts hit the mark later on!
– Give that side button and volume down button a friendly squeeze together for a few seconds. They’ll appreciate the attention!
– When the menu pops up, just tap on ‘Power off’ and confirm with your unlock code. You’ve got this!
Step 2
– Warm up the edge of the back cover by smoothly gliding the hot air tool over it. You’re doing great!
Watch out for those fingers! After heating, it’s important to keep it cool enough to touch. Heat the back cover just enough so you can handle it comfortably.
Alright, let’s tackle that stubborn back cover! It’s glued on there pretty tight, so first things first: we need to give it a little love with some heat. Grab your trusty hot air tool, whether it’s a heat gun or just a regular hair dryer, and warm it up! This will make it easier to get that cover off without any hassle.

Step 3
To create a snug little space between the back cover and the display unit, grab yourself a flat, stable tool. We suggest the iFlex, as it boasts some impressively sharp edges that slide right in with ease. Happy repairing!
– Grab a suction cup and stick it to the bottom edge of the back cover, then gently pull it upwards. While you’re at it, slide the iFlex tool between the display and the back cover for a smooth separation.

Step 4
– Carefully run your tool all the way around the back cover to gently loosen it, piece by piece. Take your time, and enjoy the process!
– Insert flat picks underneath the back cover at regular intervals. This will help keep the glue from sticking back together. You’re doing great!
Hey there, just a friendly reminder: when you’re working on the camera module, make sure you don’t push your tool in too deep. We suggest using a hard plastic pick here—it’s designed to keep things safe and sound, so you can’t go wrong with it!
To keep your device’s case looking sharp and avoid any nicks from the iFlex’s pointy edges, it’s best to switch to a plastic tool like the iPlastix as soon as you can. You’ve got this!
Step 5
– Now that you’ve successfully popped off the back cover, it’s time to say goodbye to those plastic picks—remove them all with care!
– Once that’s done, give them a little unfold and set them aside for a moment. You’re doing great!
Step 6
5 × 4.9 mm Phillips
Keep your screws in check and avoid the dreaded screw loss! Grab a handy storage solution like an old sewing box to keep everything organized. For an extra boost, our top-notch magnetic pad ensures that nothing goes sliding off the table. You got this!
– Start by loosening those five Phillips screws holding down the charging coil cover. You’ve got this!
– Once you’ve got them free, place them on your magnetic pad so they don’t go wandering off.
Step 7
Be sure to unplug that battery connector right away to keep any pesky short circuits at bay!
– Gently lift the metal cover of the NFC antenna like you’re unveiling a surprise!

Adding a new adhesive frame? That’s totally up to you! If your current one is still holding strong, there’s no need to swap it out. But if it’s showing signs of wear or isn’t sticking like it used to, we suggest putting in a fresh adhesive frame for the best results. Remember, if you need help, you can always schedule a repair.
