Repair Steps
Remove the back cover
Remove the back cover with heat, if you don't have a heat mat to hand, a hair dryer will do. The device should be hot to the touch. Insert a slim pry tool beneath the back cover, enough so separate it but not so far into the phone's body as you may damage something. Unadhere and place the back cover to one side.
Remove the main board cover
9 Philips head screws cover the main board cover. Remove these (fig. 1) and gently remove the main board cover to expose the board connections.
As with all repairs, disconnect the battery (right side) from the main board to avoid any shorting. You can gently bend it away to prevent it reconnecting during repair.
Disconnect the screen (left side)
Now is a good time to test your replacement screen works.
Pull up on the green tape on the battery with your hand to release it from the battery jacket.
If you're experiencing difficulty, feel free to heat the device up from the screen side. This will loosen the battery adhesive.
Take out the battery jacket and place it on the battery once again.
Remove the screen
Heat the screen well to soften the adhesive. Use a suction cup, or insert a thin metal tool or razor blade in between the screen and the housing, gently pry up to release the screen, taking care of any glass that falls out.
Apply glue/tape to the housing
Clean off any remaining glass or adhesive on the screen side of the housing.
Apply B7000 or some other electronic glue, or a pre-cut adhesive if you have it, to the screen side housing.
Place the new screen into the housing, ensuring the screen cable threads properly through the opening where the battery once sat.
If using glue, hold the frame and screen together with clamps or rubber bands for at least 30 minutes and allow the glue to cure.
Reassembly
Test the phone to make sure all the functions work.
Replace the battery, main frame cover, screws.
Remove excess adhesive from the back cover and apply double sided tape or pre-cut adhesive.
Re-apply the back cover to the frame.
