On HTC’s Windows Mobile 2005 devices updated with the AKU2 firmware it was possible to invoke the Engineering Test Mode (Engineering Mode) by doing the following:

1. Adding the following keys to HKLM\Software\HTC\EngineerMode:
"BuildInEngineeringModeApp"=dword:00000000
"LaunchEngineerModeAppDialStr"="*#*#364#*#*"

2. Saving file GSMTestMode.exe to /Windows and starting it after having rebooted the device

The HTC Engineer Mode presents a lot of operating parameters of technical values (not so detailed but similar as in Nokia’s Monitormode menus).
That’s how these screens look like

However on the HTC TyTN the Engineering Mode no longer works.

If invoked the screen looks like that (see attached image):

Could anybody try to find out the reason why it does no longer work and try on a workaround ?
Maybe there is information leaked from HTC or maybe there is even a new Engineering Mode application available ?

Who could succeed in doing that ?
