Can't install .JAR files

[chalesboy]

Hi.

I got the A780 with asiatic firmware over internet shoping. I installed lots of .JAR apps and games, but I wanted to flash my phone to get my own language. Got this dutch firmware:

Now I have my phone in spanish, and installed neo-package, ezxpackage and other mpkg stuff, but I can't install .JAR files like before. I always get a message saying: "Instalation eror - Invalid Package"

Can any item installed be blocking or jamming my .JAR installation protocol? or something like that?

I'm not 100% sure anymore this is the one, but I'm pretty sure this is the most recent firmware I installed recently:

all European languages included like Spanish, French, Italian, Dutch, German etc.
After installing this firmware I install optimized flex to be able to install mpkg files http://www.motorolafans.com/forums/viewtopic.php?t=1462

I also have an Asian device (without gps)
Flashing this firmware initially failed after 95% or so, the reason for this is that gps is not available and it wants to install gps firmware (I've read that on a thread somewhere on this forum)
No worries about this small inconvenience because even with the flashfailure it works flawless after installing.

I don't know why you have a jar install problem, but I can recommend you above firmware. I can install jar, mpkg and I can install themes now.. whoopee!

Optimized setup solved my problem, YAHOOOOO

Now I can install .JAR and .MPKG files... I just got this message in chinesse at main screen that I want to remove from there.

Can I remove this chinesse message, or there is an european version of this optimized setup ?
