If You can manage to get into START:SETTINGS:SYSTEM:SYSTEM INFORMATION You can read out what ROM version You have (My Axim says A00C (01280400EN) This is the english version with BT and WiFi. I could not find img file for this version but saved my X3i with a ROM backup (RIS) from an older X3i i have had.
You have to search trough the forum and Dell to try to find a ROM update, that exe file probably have the img included. It's importatnt to get the correct one for Your Axim. I have an A04 img file, but that one is not for my model...
