Windows Mobile Device ID

[ofueckert]

Hi Guys,

I am wondering where the Device ID is hardcoded and if it can be overridden by any software or bootloader hack.

I have a corporate mail windows desktop software that checks for the reported device ID. It was configured to look out for a Cingular 8525 (HTC Wizard) which has a device ID of [WIZA200] however after I upgraded to a a HTC Trinity [TRIN100] it refuses to sync with a an error message of pointing to the invalid device id.

any advice/help appreicated how I can make my Trinity ID look like a Wizard ID to sync again.
cheers,

Ollie.

Probably a stupid question, but wouldn't it be simpler if you go to the administrator (or who ever is in charge of the tech staff at you company) and have your account changed for the new device?

What you want can theoretically be done by editing the ROM image (I know this ID is something PB sets) but I don't think anyone ever tried it (at least on this forum).

One more thing: why is your software checking device model? This would be fairly useless as a security feature. Are you certain it is not locked on your phone IMEI or UUID - in which case my first suggestion is the only way to go.

I'm with levenum on this. Checking if the phone is a WIZA or TRIN is rather an extra effort that does not provide much security or identification purpose. E.g. there are like millions of WIZA out there that is able to by pass this 'security' or be identified as.. you?

IMEI on the other hand, is unique to each device, for security and identification purpose, thats most likely what it is doing. ELSE, if it were to be like a login name, you can try changing the one at 'Start'->'Settings'->'System'->'About'->'Device Id'

Thank you for the suggestion guys. I have tried...

The reason they are checking for ID is, that they would like to ensure that only "standardized devices" are used.
However, you probably can appreciate that I'd prefer to use my Trinity rather than a Wizard.

The are not checking for the "soft" device ID that is user configurable as the access security is done on application level with a login password.

The other problem is, talking to a IT organisation which supports 40,000 people. Not exactly easy to get a one off change done ;-)

levenum, what do you mean with PB ?

BTW the application is CREDANT password manager.

Pretty sure, its locked to Device ID based on the extract from Log of credant connecting via Active Sync:
DevOS=PocketPC
Device=TRIN100
Cert=M2M
SyncOS=ActiveSync
SyncVersion=4.5.5096.0
ProcessorClass=2577

cheers,

P.B. stands for Platform Builder, it is an MS tool that creates ROM images (thats what OEMs use).

I understand your frustration about dealing with IT but trust me - it is a lot easier than actually changing the device ID (if it is at all possible).
Plus if your company has 40000 employees I am sure you are not the only one using Trinity or at least something other than Wizard. Maybe group pressure can help expedite the proceedings.
