HTC Field Test Mode/Engineering Mode

Some HTC Windows Mobile phones can provide field test display.

For HTC TyTN, there is an application fieldtest.exe used to display network information.

Old ROM version may not work with the application. You can get more information in xda-developers forum.

Some HTC phones can activate the FTD by specil code: *#*#364#*#*
To see the engineering mode screen, follow the following steps:
- Use Total Commander to navigate to \HKLM\Software\HTC\EngineerMode
- Assign a value of 1 to BuildIEngineerModeApp
- Close Total Commander and perform a soft reset by holding the Power Button for 5 seconds
- Power on your device, and wait for it to boot
- Now dial *#*#364#*#*
After about two seconds, a screen will appear with technical information about your cellular connection.

The code works on HTC Diamond and Touch.
