Read this website's Legal Guidelines and make sure you understand the risks of this repair. Place your T-Mobile myTouch 3G on a clean flat and soft surface, such as a rubber mat or a piece of soft cloth and get the required opening tools
|
|
|
Step 2
Turn your myTouch 3G on the front and remove the battery door.
|
|
|
Step 3
Remove the battery.
|
|
|
Step 4
Take note of the Torx screws on all sides that hold the backplate in place.
|
|
|
Step 5
Remove the screws as indicated in the pictures: the screw on the left hand side of the back that needs to be removed.
|
|
|
Step 6
Remove the Torx screw on the bottom of the mytouch. |
|
|
Step 10
Remove the Torx screw at the top.
|
|
|
Step 13
Remove the second Torx screw at the bottom.
|
|
|
Step 12
You can now take off the antenna cover on the bottom.
|
|
|
Step 16
With all the screws removed you can now pry the backlate off from the mytouch using the safe opening tool.
|
|
|
Step 17
Work your way along the edge wtih the safe opening tool so that every latch holding it together is released so it can be taken off.
|
|
|
Step 18
Remove the plastic backplate from the phone. The logicboard is underneath.
|
|
|
Step 19
Remove all phillips screws visible that hold the two logic boards in place as indicated in the image.
|
|
|
Step 20
Remove the Phillips screws on the top logic board.
|
|
|
Step 21
Remove the Phillips left screws on the top logic board.
|
|
|
Step 22
Now the ribbon cable at the top of the phone can be released from the connector. It's best to use the safe open tool for this step, ignore what you see in the image.
|
|
|
Step 23
Ease it off with a tool so that you do not tear the ribbon cable. Work slowly and patiently.
|
|
|
Step 24
There is a small ribbon cable in the center of the top logic board near the battery compartment that needs to be removed from the logicboard.
|
|
|
Step 25
This one is smaller and is on the bottom half of the phone.
|
|
|
Step 26
Again remove the cable using a safe open tool, so that you do not tear the cable or short or damage the contacts.
|
|
|
Step 27
Now the logicboard can be lifted out of the casing. Make sure you do this from the side that had the large ribbon cable attached first. It is from left to right if you are looking at it properly from top to bottom.
|
|
|
Step 29
Once lifted from the one side it can then be turned over to remove an antenna connect and another ribbon cable.
|
|
|
Step 30
Remove both connections carefully.
|
|
|
Step 31
We are not going to lift off the bottom myTouch 3G logicboard.
|
|
|
Step 32
DO THIS SLOWLY. There are 2 more ribbon cables underneath that need to disconnect without being torn.
|
|
|
Step 33
They should naturally come off. But do it slowly to make sure.
|
|
|
Step 34
Now the second myTouch 3G logicboard can be fully removed.
|
|
|
Step 35
This is what the mytouch looks like when both logicboards are removed. You can now reassemble your myTouch 3G with the new parts following the steps in reverse order.
If you continue assembly of the front plate you can replace the myTouch 3G Screen as well.
