    • It is recommended to let the battery discharge before starting. It's a precaution to prevent the battery from catching fire if punctured.

    • Remove both T2 screws

    • Slide off the plastic piece by lifting out and then up

    • Slide plastic and spring assembly off the rail

    • Do this on both sides

    • A hairdryer on high should work you may have to use it for longer

    • Heat the glass screen with heat gun to soften the adhesives

    • Start the next step on the opposite side of the Fitbit wording below the glass. This is due to the display cables being located there

    • Insert a razor blade between the glass and the body

    • Keep going around the rim of the display until loose

    • Liftoff both display connectors

    • Remove Display Assembly

    • Connect The new screen (basically step 6 in reverse)

    • This step can be a bit fiddly to get right

    • Then perform the step 5 in reverse to put the metal shield back in

    • Reconnect battery connector

    • if the battery wasn't dead before repair it should turn on now

    • Put the battery back in place

    • When I was replacing the screen I also replaced the battery that's why the battery changed.

    • Add a thin layer of E-6000 glue around the casing

    • Make sure to cover the entire surface that makes contact with the screen to keep the device waterproof

    • Flip down the screen and remove any extra glue that squeezes out

    • Take a rubber band and wrap it around the device, this will ensure the display stays in place until the glue cures

    • With the rubber bands on go to step 1 and reverse the steps to reinstall the band release

    • The glue will take between 24 and 72 hours to fully cure

    • When the glue is fully cured remove the rubber bands

    • And walla you now have a repaired Fitbit Charge 3
