Is it possible to replace home button on iphone 4

Restoring your device with DFU mode rewrites every bit of the software and firmware. Sometimes, this takes a while. Follow the instructions in our guide to restoring your iPhone using DFU mode. If that doesn't work, you know your Home button definitely has a hardware problem.

One of the other tips below can still help you fix it, though. As you use the Home button throughout the life of your iPhone, it's likely to collect a buildup of dirt and grime. That filth might clog the mechanism, which could explain why the Home button stopped working. Unfortunately, this tip can't help if your iPhone 7 or iPhone 8 Home button isn't working, because those devices don't feature a mechanical button.

The Home button connects to other components inside your iPhone using a fragile cable near the charging port. Some people have fixed their Home button by applying a small amount of pressure in this area, presumably because it reconnected the cable. Of course, you need to be incredibly careful when trying this.

You don't want to break anything inside your iPhone. You also need to be careful you don't snap the Lightning or pin connector off inside the charging port, which can be almost impossible to remove.

You should find that this fixes the Home button on your iPhone for a few weeks or more. However, you'll probably need to get the Home button on your iPhone replaced eventually. With an iPhone 7 or later, you can't replace the Home button, so you may need a replacement device instead.

If your iPhone is less than a year old, it might still be covered by Apple's one-year warranty. That means you can make an appointment at the Genius Bar in your nearest Apple Store to have them repair your Home button for free.

Unfortunately, most iPhones with a physical Home button are more than a year old. Remove the small circular white sticker warranty sticker and water indicator covering the screw near the battery pull tab.

Use the edge of a plastic opening tool to gently pry the following connectors up and out of their sockets on the logic board:. Standoff screws are best removed using a standoff screwdriver or bit.

In a pinch, a small flathead screwdriver will do the job—but use extra caution to ensure it doesn't slip and damage surrounding components. When reassembling the device, this standoff sets the height of the Wi-Fi shield removed in step If not torqued down, the shield will be above the plane of the frame and the back will not slide into place in step 2. The shield should be flush with the headphone jack.

When reassembling the motherboard, ensure that its edge sits under the circled standoff, otherwise the screws will not fit.

When reassembling ensure that the small rubber spacer attached to the top of the motherboard is in place. Carefully remove the logic board from the iPhone, minding any cables that may get caught.

Be careful not to damage the small gold prong marked in red, near the top as it's very fragile. On reassembly, be careful not to trap the lower antenna cable beneath the logic board. Before re-fastening the speaker enclosure to the inner frame, be sure the four small EMI fingers rest below the lip of the LCD frame. Before reassembly, be sure to clean all metal-to-metal contact points between the EMI fingers and the internal frame as well as the brass screw mounting point with a de-greaser such as Windex.

Remove the three large-headed 1. Tip: It can be tricky, but it is also possible to just loosen the large-headed 1. Remove the small-headed 1. Carefully insert the edge of an iPod opening tool between the rubber bezel around the front glass panel and the steel inner frame.

Carefully pry the upper edge of the front panel assembly away from the steel inner frame. Slowly and gently lift the top edge of the front panel assembly away from the steel inner frame. Continue to rotate the front panel assembly away from the steel inner frame until it slowly begins to peel off the adhesive applied below the home button area. It may be easiest to insert a spudger at the top and work it around the edges, spreading gently as you go.

Carefully pull the lower edge of the front panel assembly away from the steel inner frame. Be careful, if the home button sticks to the front panel you may tear the home button cable. Do not pull the front glass completely away from the frame.

Doing so may result In damage to the digitizer cable. If the glass is cracked which it probably is since you're replacing it removing the panel is likely to cause it to bend, kicking off small shards of glass. Before you do this step, cover the front with clear tape, then perform the actual removal over a trash can. Protective eyewear would also be prudent. De-route the digitizer and LCD cables through the steel inner frame, and remove the display from the iPhone.

When reinstalling the display, carefully straighten the digitizer and LCD data cables, and feed them through the slot cut in the steel frame. This photo shows the display assembly being installed incorrectly , with a fold in the digitizer cable. When the front panel has been correctly installed, both the LCD and digitizer cables should be immediately next to one another and should be the same length, as shown in the second photo.

If the digitizer cable has not been installed correctly, it will not reach its socket on the logic board. Do not attempt to pull it through by force, or it will tear. Remove the display assembly, straighten the cable, and feed it through to its full length, as shown.

During reassembly, do not touch the metallic area at the base of the LCD data cable, as this can cause problems with the LCD. If you do touch it accidentally, clean it gently with an alcohol wipe before continuing. Use the edge of an iPod opening tool or your fingernail to lift the home button ribbon cable retainer. Be sure you are prying up on the cable retainer, not the socket itself.

Do not excessively strain the home button ribbon cable, as it is very thin and delicate. Also, be careful with the two small electronic parts on the ribbon cable. It is very easy to damage them with tweezers.

De-route the home button ribbon cable through the inner case and remove the home button from the iPhone. When installing a new part, there may be a protective plastic film on the home button. It can be removed with a spudger or your fingernail.

They are located to the right and left of the dock connector. Put the screws in the same compartment of your organizer tray. 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. Remove the screw on the battery connector using a Phillips screwdriver see figure 1. Put the screw in a separate compartment of your organizer tray. If the contact point 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. 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. The antenna cover is under the battery connector. NRemove the cover and put it in the same compartment of your organizer tray as the Phillips screw you removed before.

See figure 1. Now remove the battery. Insert the flat end of the spudger into the space about 1 cm to the left of the volume down button between the battery and the outer frame, and slowly lift the battery see figure 2. Now you can also disconnect the antenna connector by carefully pulling it off the plug head using the spudger see figure 3. Fold the plastic tab with the warning over and press it firmly onto the lower adhesive strip.

Of course, you can also remove the plastic tab. Remove the two Phillips screws from the dock connection cable and remove the black silver for newer models cover see figure 1.

Now you can carefully detach the connector by using the flat end of the spudger to lift the connector again. Alternatively, you can also use your fingernail again see figure 2. Remove the five Phillips screws. See figure 2.

Lift the cover out of the phone. Note that the cover is hooked on in two places. See figure 3. Now you can disconnect the following five connectors. Be very careful see figure 1.

Place the pointed tip of the spudger very slightly below the contact and lift it up see figure 2. Lift the camera connector to remove it like you removed the other connectors and take out the camera.

Remove the white water indicator sticker.
