Can I upgrade XDA II 1.72.01ger to Windows Mobile 2005?

[Polaris431]

When I registered with this forum I was presented with a list of possible XDA II models that I could select that is used to indicate to others what model I have. Unfortunately my version is not in the list. Here are the specs:

R 1.17.00
G 1337.28
D 1.72.01ger (This is a german OS)

The OS doesn't say "Windows Mobile 2003" but rather:

Microsoft Pocket PC
Version 4.20.0 (Build 14053)

My XDA II has 128 MB of RAM.

I would like to know whether its possible to upgrage my OS to Windows Mobile 2005. The english version would be fine. I don't want the german version anyway. I've read a lot of posts but it isn't entirely clear whether it's really possible. Does upgrading only work with some version of the XDA II and beyond that version while not working for versions prior to it? Or can this upgrade be made to any version of the XDA II?

Can someone point me to something that would give me a strong sense of assurance that it is possible. Without this assurance I won't chance it. Last thing I need is a dead phone. The major reason I want to upgrade is to eliminate the problem of losing everything if the battery dies or is removed.

Thanks for your help.

Have you or do you know anyone who has *successfully* installed Windows Mobile 2005 on a version of the XDA II that I have or an older version in a language other than english?

if you go to the window 2005 forum in the himalaya group it's almost mainly users who installed 2005 on their himalaya devices

well that and ppl who did it on their blue angel too

"XDA II that I have or an older version in a language other than english?"
not 100% sure what you are saying here
if you by version mean himalaya or if you are talking about your rom version if the later rom version have nothing to do with it really
if you mean device as in himalaya then roms hare 100% made for a device windows mobile is not like normal windows
so the rom for himalaya is MADE for himalaya

and about language then it's a part of the rom only if you change rom you change language to the language of the rom you change to
