K550im cannot install java apps

[joshua]

When I try to install any java application to the K550im (imode phone)either through the MPE or via the phone menu, it is not installed. The MPE gives an error "OBEX errorcode :C3 Forbitten operation is understood but refused".

Any ideas why is that? Is the phone locked in any way? Can it be unlocked? Are java apps incompatible with imode phones?
TIA

I don't know if imode phones allow no javas, but if its not possible to open a *jar-File directly in the phone then i think t´his functionality is locked.

Is there a utility to unlock the functionality?
Is there a utility to backup the existing internal firmware (in order to restore it afterwards in case of problems) and then try other firmwares from the ordinary K550i to check the java functionality?

Maybe you can flash the phone with the original software. But this is not the right forum to discuss about this topic. I have not much experience in flashing phones.
