This is a nice picture tutorial by maxyn

1. Get an E398 phone, a screwdriver and free time

2. Remove the screws the way shown in the picture below:

3. Now you have to remove the case from the main plate. First remove the top part and then the bottom. Hold the display, because it can fall

4. To the main plate you have the following connected - display, keyboard, speakers and camera. First remove the display. There is a small connector at the end of it

5. Now it's time to remove the keyboard. It's very easy, but be careful with the joystick - do not try to remove it

6. Now comes the block of loudspeakers. It is very wirdly arranged, since it is removed together with the camera. They are connected to the main plate with two platic holders. When you press one of them a little the entire construction will fall. Here you will see how the camera is connected with the plate - carefully disconnect this contact.

7. This is almoust everything. Only few minor details left - the sim card holder, the battery under the keyboard and flash card

8. You are ready. Everything is disassembled. Good luck in assembling it back (use the reverse order of the tutorial)
