I have successfully upgraded a Titan to WM6 and it has made huge improvements to some problem areas- especially with bluetooth connectivity (as per previous posts on this topic) One small problem- the device always thinks it is roaming.- Is this just a matter of re doing the Nam or is it because software is not "NZ" version..any help?
Its probably that you are using a non-nz version, without the changes made to the software to make it think that Telecoms CDMA network is the home network (there may also be other 'settings' missing for the network too).
This is because the radio that you flashed (or was included with the ROM) is from an American or Canadian carrier. To fix it you need to reprogram some data in the radio EPST. You need to know the A-Key (as far as I know, this is blank on Telecom but nonetheless is necessary), the MDN, the MSID, M.IP and the Security data.
You'll need the SPC code to access the EPST, which I can't post here, but Google is your friend. Once you reprogram the radio, you should be set.
It will have the wrong PRL loaded on to it. Sounds like you ran Sprint or another carriers ROM/RADIO image and let the custom settings load.
Flash back to WM5 Telecom Stock ROM and Radio, then flash back to WM6 using another carriers ROM, once this is done and the device reboots DO NOT go past the inital setup, reset the Titan into bootloader mode and then load in a cooked TNZ 6.1 kitchen ROM (Google).
One this is done you will have a NZ PRL loaded, all the TNZ settings a loaded on to the phone and you are away.
