I'm trying to update the EHS5-E firmware to the latest version. I ftp the three files onto the FFS, disable the previous JAR followed by a SFDL=2 command.
After 5 minutes, ATI1 shows that the latest firmware has been loaded.
I try to load the JAD file using the AT^SJAM=0,A:/JRC-1.56.58.jad command and get an error after a timeout of about 30 seconds, error unknown,
When I try to upgrade using the gWinSwup application to perform the same upgrade I get the error message
"ERROR: Installing MIDlet[JRC-1.56.58.jad] fail, check that there is no signature conflict!".
I can recover by going back to 3.001-14 which works well.
I did find a reference to this error in google but the issue there does not seem to apply here.
