Guide with all the necessary steps so that you can change the headset of the Sony Xperia Z1 (L39H) yourself.
The back cover, like the screen, is glued and sealed to ensure the tightness of the phone.
To open it it is necessary to heat the lid to soften the glue and thus remove it easily.
We suggest 2 methods that will be explained below:
Simply heat the back cover with the air jet for a few seconds.
Excessive heat from the gun can damage the equipment. Use it with caution at the minimum power and in short radiants.

To heat it evenly, it is necessary to interrupt the microwave every 30 seconds to distribute heat throughout the HOT GLASS with your hands.
Apply heat with the HOT GLASS directly to the back cover.
Insert the tip of the pick into the small slot on the top.
Move the spike all the way around while holding the cover with the suction cup.
Unplug the flex from the flash and microphone.
Remove the 9 Torx screws that hold the intermediate housing.
Apply heat back to the intermediate housing and traverse the contour with the spike as you did with the back cover.
Disconnect the flex from the battery of the motherboard.
Peel off the battery, prying with the opening tool.
Unplug and remove the rear camera.
Disconnect the vibrator from the base plate and remove it from the housing with the help of the clamps.
