Done! With the help of Buzz Lightyear I managed to get my two RTM ROM Images of magneto flashed onto my MDA2. And it runs flawlessly so far.

And the best of all: All of the Memory is usable. Now I have to figure out how to get the Lotus Notes Sync-Conduits working…
i can´t believe it! With which image is that possible?
I tested the WM2k5 1.60c.00WWE XDA2 HIMALAYA from http://buzzdev.net/index.php?option=com_remository&Itemid=68&func=select&id=9
but i dont came (with the Tool for resizing Himalaya (DiskOnChip) Patch) not over 30 MB for Storage.
NICE TO ME
