Introduction

How to replace the display assembly on the Telstra Dave 4G ZTE T83.

Image 1/3: Remove the two H2 screws, on either side of the phone. Do not lose the red seal that are on the screws. Image 2/3: Using a prying tool work off the back of the case. Ensuring not to lose the port covers. Be careful to note the position of connector covers. Have the tabs at the end of the connectors in place before clipping the phone completely back together.

It's a bit tricky getting the cover off as the glue around the speaker doesn't want to let go! Note: There are small clips around the edge - work from each of the ports and lever the yellow edge gently out and away from the thin black edge around the screen, starting from near the side screw holes.

Pulling the tabs is optimistic! I carefully levered the battery up with a fine (but strong) screw driver. The glue strips used are very tacky and I managed to leave most of them in place and simply stuck the new battery back onto the existing strips. Note: The old battery bent a bit as it came out but still indicates that it is holding a bit of a charge.

how do you lift the battery with the blue tabs , its very hard to lift the battery i think i might have damaged the battery , it's kinda soft and not rigid like other phone batteries and stuck to the board ?

Hi Chrisorius. You do not lift the battery with the tabs. The tabs are meant to be pulled so they come out from between the battery and the logic board. Then you should be able to lift the battery off the board with ease. Doesn't always work that way though, so have a pair of tweezers handy so you can grab the ends of the tabs to continue to pull them out. It is better to persevere with this than to lift your battery and damage it or your logic board.
