Installing MIDlets is denied on Series 80 2nd Edition (Known Issue)
When trying to install a signed MIDlet to the Nokia 9300 or the Nokia 9500 Communicator, the following error is displayed: "Application installation denied by Java server.
The trick to installing a signed MIDlet in the Nokia 9300 or the Nokia 9500 Communicator is that you need to have the device switched on. In other words, the "mobile device" side must be switched on and a SIM card must be inserted. The installation process accesses the SIM card, and this cannot be completed without the device side on.
Turn the "CMT" side on.
