Hi,
after searching hours and hours in the web for a solution of the "change ROM language" question, here is how I fixed it:
ok, we have one english speaking X30 (version A02) and want upgrade (or downgrade

) it to german.
First you'll need the english (R87096) and the german (R89371) ROM update. Extract both in separate folders.
Second seach for the image file of your Axim model:
Non-combo models:
P16A_ALL_N_10070400EN.IMG (english)
P16A_ALL_N_10190400GE.IMG (german)
Combo models:
P16A_ALL_C_10070400EN.IMG (english)
P16A_ALL_C_10190400GE.IMG (german)
Third copy the first 7 lines (from x00 to x70) from the english ROM-image file (N or C) to the german ROM-image file respectively.
Fourth overwrite the english image with the german one.
Fifth Start "setup.exe" from the english archive with your Axim X30 in the (attached

) craddle and it will be updated with the german ROM.
