Upgrading MDA Vario II with HTC Rom - open questions

---

Hi comm!

I have a T-Mobile MDA Vario II, Rom Version: 1.21.

Can i upgrade my PPC with the released WM6 update of HTC without any problems, although i have a differently branded TyTN? Will all functions work (telephone, internet)? And can i downgrade my WM6 to WM5 easily or can I reactive my current system status with a backup (SK Tools)? Last but not least, what will the warranty say?

Thanks for your efforts.

PS: sorry for all these maybe stupid questions...but i´m just a beginner =)

upgrading to WM 6 worked for me as did unlocking ;)


If you do not use an official T-mobile ROM update forget any warranty, unless you're able to downgrade to the original one

I have an original Rom from T-Mobile. Do you know what happens with the warranty of T-Mobile when you unlock the CID? Does the CID still will be unlocked if you install another Rom? Can you lock it again?

It won´t be possible unless you downgrade to your old ROM again. I am not sure if that´s possible, though.

I went along the way described at http://www.mrvanx.org/cms/index.php?...1&limitstart=4

If you follow the directions including the upgrade to wm6 from Custel, you can afterwards install the German WM6 version from HTC. It won´t work directly. The CID will stay locked and the HTC cannot be installed until you installed the CUSTEL version.

I think the T-Mobile contract does not allow to modify the system in this way.

Using the search function gave me thread as the first result.(Couldnt find any how to guides)
So.. What do i need to do to upgrade my ROM? i have a fresh MDA vario II just got repaired from the shop.(Nothing to do with bricking if you;re wondering)
Can some one please give me a simple step by step guide on how to upgrade.
Thanks a bunch
