Unhappy WTF have I done?? No longer able to copy to device :(

Please Login to Remove!

Hey all,

3 months ago I made an app for my blackberry. I have a Blackberry 8310 (with OS version I purchased the signing key thing so I can copy the apps to my phone. All worked great.

Today i tried to make an update to the app. I noticed I had 2 versions of the JDE installed ( and From what I have read I cannot use a JDE with a greater version than my phone is using. However, after looking at the older JDE, I swear I didn't use that. It doesn't look at all like the JDE I was using before... and the newer JDE is what I remember using.

The big problem is : I load my app in the older jde and when I try and "request signatures" it fails saying my password is incorrect.

I try "requesting signatures" with the newer JDE and it is successful. However, when i try and use the javaloader and load the app on my phone, it says "Error: file is not a valid Java code file" (which I believe is because the versions are incorrect).

I had this working 3 months ago. Nothing has chnaged as far as I know. What is going on? :(

Thanks for any advice you can give!!

I would download and install the 4.2.1 JDE, then copy the sigtool.* files from the /bin directory of the "working" JDE installation.

And you are correct, your 4.7-compiled code won't run on the 4.2 device.
