"Tech Mode" on SE phones...

[uttangg_88]

Ways to activate TechMode:

enter "*585*0000#" in standby mode + Send button
enter "*585*0000" in standby mode + Call button

You will see on the screen:
QUOTE
TechMode started


Go to My Shortcuts -> you will see TechMode application.
You can see the TechMode application in Settings->Mobile Networks.

There are 3 screens in TechMode:
- GSM Channel
- GSM AMR
- GSM GPRS
For toggling between screens use joystick right.(left isn't workin on my phone:) )

To minimize TechMode push and hold return button.

On my K750i@W800i only the music button and the Walkman button work while in TechMode

On a phone TechMode screen may look like this:

GSM Channel
A BBB CC -DD EEEEF G
HHHH I JJJ K LL MM
NNN OO PP QQQ RR SSSS

On K800/K810 phones ( may be all Sony Ericsson phones ) must put this customize_upgrade.xml in tpa\preset\custom :

<customization>
<network>
<techmode-enabled>true</techmode-enabled>
<techmode-passcode>0000</techmode-passcode>
<techmode-internetbutton>false</techmode-internetbutton>
</network>
</customization>
