Remove the SIM card using a thin paperclip by inserting one end of the paper clip into the small hole on the top left corner. This will eject the SIM card from the phone. Be sure to store the SIM card in a safe location.

The screen is likely to crack as you pry it up. You should not complete this step unless you have a replacement screen available. Stick the small suction cup onto the screen. Use this to remove the screen from the phone frame in later steps. Using a heat gun on a low setting, slowly raise the temperature of the screen by repeatedly running the heat gun along the edges of the screen. This will soften the glue that holds the screen to the phone frame.

  • Use the suction cup to gently pull up on the screen while using the plastic opening tool to gently pry the edges of the screen up.

  • Once the screen has been completely separated from the phone frame, flip it to one side to expose the inside of the phone.

Using a size 000 Philips head screwdriver, unscrew the nineteen 4 mm screws. Yellow tinted kapton tape will need to be removed to get to some of the screws.

Do not use the heat gun to try and remove the battery. Heating a lithium-ion battery can cause it to catch fire.

Or buy a new phone. If I'd known how complicated this was, I'd have bought another's device.

I agree with Andy. Tutorial is perfectly explained, but construction design obviously is to avoid buyers change without risk of damage in comparison like other phones like Moto G 2nd version or Nexus 4 which are not piece of cake however is not to difficult. I hate that mind of developers trying to fix on design “battery for life of device”. That is the issue. Almost the problem is the battery. No matter how much well it is, continue being the critical lifetime part. Must need replaceable for users.
