Here are some helpful tips to assist you in completing a safe repair on your device. If you are unsure of something or have any quesions, please feel free to contact us either by phone (0508 IGADGET) or by email
- Always track your screws to avoid putting back in the wrong place and damaging your device. You can draw a picture of your watch and tape the screws to the right places or use a screw mat
- Always power down your device prior to working on it
- Make sure you always unplug the battery before attemping any component removal
- Before removing your battery, discharge the battery to below 25%. A charged lithium-ion battery can catch fire or explode if punctured or damaged
- When attempting to remove the screen, be careful not to push the blade or iFlex tool in too far or too hard, doing so may cause damage to the internal parts. Only 3mm depth is required to cut the adhesive. Draw a mark on your tool to help with depth management.
- Test the battery is functioning properly before sealing up the device
- When removing the battery with a pry bar, be careful not to go down too far as the screen flex cables route underneath the battery. Measure the depth of the new battery, then on a plastic pick, measure and draw a line to assist with depth management
- When removing the screen, it is very easy to tear the force touch gasket. We recommend having a spare force touch gasket on hand incase this happens to prevent issues after replacement.
Caution
If the new battery or the battery in your device is swollen or damaged during repair, take the proper precautions
Note
You cannot dispose of old batteries in your general waste. Find recycling e-waste centres online or take to your local refuse station.
