Is there any secret codes for SE W850i K800i K750i and etc.
Please if someone know these codes to write them in the forum.

You can access the Service Menu using the Joystick (or arrow keys) through the following combination:

>*<<*<*
> be the right arrow/direction
< be the left arrown/direction
* be the asterik on your keypad

This trick is valid on any Sony Ericsson Phone.
Thank You,

Use the Forum Search and look for "secret codes". You will find a lot of thread that provides secret code for Sony Ericsson and for other major mobile phone manufacturers.

Hello Prottotype.
To unlock/flash sony ericsson phones for free - there are a few versions of SE Tool FREE on the web (just google it). I can recommend it - it works well for unlocking and flashing. I personally use a Cruiser box but you have to buy it. I have flashed /unlocked W810i, W900i, Z530i, W300i, W550i, W800 and K750 etc.
