Schritt 1

Power down the phone by holding down the red "end" button.

Schritt 2

Push and hold the button on the back toward the direction of the arrow to unlock the battery.
Lift and remove the battery from the back of the phone.

Schritt 3

Use a push pin or tweezers to remove the neoprene screw-cover located on the upper, left corner of the back casing.

This detail is important for other Sanyo flip phones as well. I was swapping motherboards in a pair of SCP-3820s where one had a broken display, and the screws under these neoprene screw covers had me stymied for a while!

Schritt 4

Unscrew all four, 5mm Tri-Wing screws.

Tri-wing screws are a reason I hate Sanyo with my entire being. If you haven’t experienced them before, you will need to purchase a specialty screwdriver tip, often called a Y-tip or a tri-wing tip. In my case working on a Sanyo SCP-3820, the 2.5 size worked, but I could have used the 2.0 as well. No other style of screwdriver will work.

Schritt 5

Pry the back casing off the device using a spudger. Work your way along the edges to completely separate the back casing from the device.
This step may require extra force. But too much force could break the back casing.
Remove the headphone jack cover when separating the back casing. The headphone jack is located on the opposite side of the antenna.
