How can I dump or flash my treo 750v spanish rom???

[jumanji1212]

Hi!

That´s my question, how can I dump or flash (don´t know what word exactly to use) to save my spanish vodafone rom of treo 750v???? I would like to save it before I upgrade to the latest rom available, because if I have to send it to the technical service I just have to downgrade to the spanish original rom.

any suggsuetions???

thanks
