Default Dopod 818 Problem of SPL

Hi

I have Dopod818 and i want to change my ROM version because it is in chinese launguage But when i start phone i can't see any of IPL and SPL Information like all mobile shows at startup . Only it shows Windows Mobile screen at startup.

It is Currently Running on Windows Mobile 5.0 and it shows device information about OMAP 730 .

All ROM version also not working when i am trying to upgrade it . It connect ActiveSync properly.

Any clue ?
