Disassembly - Step 1 Power off your Thunderbolt

4G

Remove the battery cover, battery, & memory card

Use a small Phillips screwdriver to remove the six (6) screws on the housing

*Note that these screws are diff erent sizes so keep them organized

Disassembly - Step 2

Use a nylon spudger or pry tool to remove the front housing cover on the bottom of the device. It is held in with a small bit of adhesive. With the cover removed there are now two (2) more small Phillips screws which will need to be removed.

Disassembly – Step 3

Use your spudger or pry tool to release the clips holding the back housing to the front of the screen. Release the clips on each side and then carefully remove the metal back housing. Be cautious as the volume button will likely fall out. Put this to the side until reassembly.

Disassembly – Step 4

Use your small Phillips screwdriver to remove the final two (2) screws holding on the plastic housing. With these removed, release the upper and lower clips holding the housing to the rest of the device

Removing the Motherboard - 1

Release the single jaw connector on the bottom right of the motherboard. Make sure the flex cable is out of the way and gently lift the right side of the motherboard up. Be cautious as there are two (2) flex cables located under the motherboard

Removing the Motherboard - 2

Release the two (2) jaw connectors and remove the motherboard

Heating the Screen Assembly

We suggest removing the power button from the frame at this point using a spudger or pry tool

Now, using a heat gun or hair dryer we can now heat the front of the screen assembly. Focus the heat on the outside edges for about 40 seconds on medium heat. We also suggest heating the front for a short time

Removing the Screen Assembly

Be sure the assembly is fully heated and begin lifting the LCD from the metal frame. We suggest working the pointy end of the spudger into the slot on the bottom right of the back frame and pushing the LCD & touch screen away from the frame. Once it is lifted you can then use a pry tool to release the adhesive on the back of the LCD screen.

Separating the LCD from Touch Screen

With the screen assembly removed you can now use a pry tool to separate the touch screen and LCD screen. Gently glide it along the edges releasing the adhesive. You may want to lightly heat the assembly if the adhesive is holding strong.

Prepping the Touch Screen Digitizer

If replacing the touch screen, swap over the soft button distributers located on the keypad. This is held in place with adhesive, simply peel it up and place it over your new touch screen.

You will also need to apply new adhesive to the touch screen digitizer. Use the diagram above to place new adhesive on your touch screen, being sure nothing overlaps or is in the viewing window.

Assembling the Screens

Securely press your screens together, insuring they are properly aligned.

Attaching the Screen Assembly to Housing

Insert the new screen assembly into the front housing, insuring the cables are snugly pulled through the slots in the housing. Be sure to reinstall your power button back onto the frame

Installing the Motherboard

Insert the screen flex cables back into the motherboard. Once fully inserted, close both jaw connectors and flip the motherboard back over.

Reassembling the Motherboard

Reconnect the final jaw connector on the bottom of the motherboard

Reassembling the Plastic Housing

Place the plastic housing over the motherboard and firmly press the upper and lower clips until they pop into place. Replace the two (2) small Phillips screws

Secure the Metal Housing

Use a piece of tape to secure the volume button to the metal housing and then slide the device (top first) into housing. Press firmly along the edges to insure it clips into place.

Reassembling Front Screw Cover

Replace the two (2) small Phillips screws near the soft buttons on the bottom of the screen. Replace the small plastic cover
