iPhone 4s – Replacing the Wi-Fi antenna

- You need a pentalobe screwdriver to open your phone.

- Remove the two pentalobe screws at the bottom of the enclosure. They are located to the right and left of the dock connector. Put the screws in the same compartment of your organizer tray.2 x 3.6 mm pentalobe screws

- Use your thumbs or the palm of your hand to push the back cover of your iPhone about 4 mm away from the bottom of the phone where the dock connector is (see figure 1).

- Then you can lift the back cover at the end that’s sticking out past the phone (see figure 2).

- First things first: if your iPhone is still on, turn it off by holding down the standby button for about five seconds and following the prompt on the display.

- Remove the two Phillips screws on the battery connector using a Phillips screwdriver (see figure 1). Put the screws in the same compartment of your organizer tray. You'll need: 1 x 1.5 mm Phillips screw, 1 x 1.3 mm Phillips screw. Be careful, as the contact point on the logic board could come off. If it breaks off but the soldering points are still intact, you can solder the contact point back on.

- Now carefully lift off the battery connector by inserting the pointed ESD spudger slightly below the silver cover plate (see figure 2). If you don’t have a spudger, you can also try using your fingernail.

- For the rest of the repair, you can also use the metal laboratory spatula instead of the spudger. This may make some steps easier for you. However, we explicitly recommend using the ESD spudger produced specifically for precision electronics. Need help? Schedule a repair with us!

- Time to get your hands dirty! Remove the antenna cover, which is hiding under the battery connector. Store it safely in the same compartment of your organizer tray as the Phillips screw you removed earlier. (Check out figure 1 for a visual guide).

- Time to get started! Remove the Phillips screw on the antenna cover (see figure 1). Store the screw safely in a separate compartment of your organizer tray. 1 x 1.5 mm Phillips screw.

- Now you're free to remove the cover of the antenna cable (see figure 2). Put it with the screw you removed before.

- Use your trusty spudger to disconnect the antenna connector below it (see figure 3).

- Let's kick things off by removing the Phillips screw that’s keeping the Wi-Fi antenna snug in its spot (check out figure 1 for a visual aid). You’ll need 1 x 2.4 mm Phillips screw for this.

- Next up, grab your spudger and gently disconnect the antenna connector (see figure 2). You've got this!

- Now, it’s time to lift that antenna right out of there (see figure 3). Easy peasy!

- Time to get your Wi-Fi antenna in place! Install it and screw it in with 1 x 2.4 mm Phillips screw. Make sure it's snug and secure.

- Put on the cover for the antenna cable (see figure 1).

- Fasten the Phillips screw on the antenna cover (see figure 2).1 x 1.5 mm Phillips screw

- Let's get this party started by reattaching that antenna connector (check out figure 1 for a little visual help).

- Next up, pop on the antenna cover (see figure 2 for guidance).

- Now, it's time to click that battery connector back into its cozy spot and secure it with a screw. You'll need 1 x 1.5 mm Phillips screw and 1 x 1.3 mm Phillips screw.

- Put the back cover back on and carefully push it the last few millimeters toward the dock connector.

- Time to get started! Screw in the two screws at the bottom of the enclosure using your trusty pentalobe screwdriver. You'll need 2 x 3.6 mm pentalobe screws.

- Next up, push in the SIM card tray. Easy peasy!

- Kick things off by syncing your iPhone with iTunes or hop onto a WLAN network and hang tight until your time is back on track.

- Pop out the SIM tray, give that SIM card a little love, and then slide it back in.

- Switch on airplane mode for a moment, then turn it off again. Easy as pie!
