T68 Teardown

I decided to do a teardown on my T68 as I broke the screen (I sat on it) and I've just ordered a T68 plus from banggood.com. Edit: I have now rebuilt my T68.

I've removed the back cover by prising it off with a small flat-edged screwdriver. I started on the side next to one of the buttons, and slide/twisted the screwdriver along to undo each of the clips that hold the back on.

The plastic back is uninteresting except for the copper shield.

With the back off, there are about a dozen (14 actually) tiny Phillips-head screws that hold the innards to the front bezel. Off they come. There is one small screw right at the bottom to the left of the micro-USB port.

The front bezel is not that exciting.

The screen is held down by two strips of black tape on either side, and has three flat connectors to the main board.

The connectors are relatively easy to detach, just wiggle them carefully and ease them out.

Here is the front and back of the display with closeups of the identifying marks.

The other side of the main board is very dull.

The main board still runs and I can get an adb shell onto it with the screen removed:

$ adb shell
shell@android:/ $ df

The battery seems to be either glued down or held down with double-sided stick tape. I haven't tried to remove it. There is a connector to the battery, so it can be replaced without soldering.

I did try to reattach the screen connectors. The large one is easy, just wiggle it back in. The connector with the surface-mount chip is harder, but there is a piece of plastic near the end, so you can mostly wiggle it in and then use a thin flat screwdriver to push it in the last bit.

I found the small one to be the hardest. By hand I couldn't get it in. Then I tried a pair of needle nosed pliers and in my attempt I damaged the on-board socket. Eventually with some persuasion I was able to get it back in. However, the screen still doesn't work, sigh.
