How to upgrade a German T-Mobile MDA compact III to WM6?

[bzn]

Hi everyone,

I'm looking for someone who already managed to upgrade a german T-Mobile MDA compact III to WM6. Has anyone experiences with this? It's my business phone and I don't want to break it.

1. Is there any chance to reflash the old WM5 ROM if something goes wrong?
2. How can I save the old ROM!?
3. Do I need to setup any regional settings if I use the O2 ROM for example?

Thanks for all answers!

You shurely can use the O2 ROM. Regional settings? You can change the regional settings in the ROM, but you don´t neet to if you use the german version of the O2 ROM.

There is a way to make a backup of your curent ROM to a storagecard. Use the search..

You should make a backup of your pim (contacts, tasks, calendar etc.) with PPCPimBackup because you can restor them with thiis program, but not with SPB Backup..

Is your phone sim- or netlocked? Normally the german tmob devices are..

IMPORTANT: You can update - but before you flash your rom with any new os (like the O2) do the "uspl" (CID Unlock) first!

Look here http://forum.xda-developers.com/showthread.php?t=308242

I have updated mine. Everything works fine, but the menues are in English.
The phone must be CID unlocked then you can flash any ROM you like. You can also find a CAB for T9 input in German.

Thanks a lot guys for all the information. I'll report later if it worked...

Thanks for all your information!

Everything worked fine.

At first I tried to make an backup, but I was not really successful, see here: http://forum.xda-developers.com/showthread.php?t=312871&page=5

But it didn't matter because I found a german wm5 rom for t-mobile:
XDA-DEV FTP -> "Uploads/Upload/Official MDA Compact III ROM/MDA Compact III German.exe"

So here is a conclusion for all noobs, like me:
1. Run USPL, get it here and read all the stuff: http://forum.xda-developers.com/showthread.php?t=311403
2. Patch any ROM you like, for example one of those: http://forum.xda-developers.com/forumdisplay.php?f=362 or get one on the xda-dev ftp

I tried three or four of the ROMs from the forum, it was possible to flash them all, but I had to try it twice to "remove" the german O2 ROM (flash another ROM over the O2), but maybe I did something wrong in the first place.

What I would finally like is a T-Mobile branded german WM6 ROM. If anyone could give me some tipps where to start, I would appreciate it. I think it should be possible to extract the german O2 WM6 OS and somehow mix it with the T-Mobile stuff from the WM5 ROM. I know there is a lot information here on the forum, but any hint is nevertheless very appreciated ;)

what t-mobile stuff you like on phone?

try the Black&Blue 3.7 GERMAN ROM or wait 1-2 month for the HTC WM6 ROM or cook by your self :)

*ps i have an O² xda orbit but my provider is t-mobile. i currently use the WM6 GER of O²
