I have just bought a T-Mobile 7105t Unlocked blackberry and when installing a theme I got the 400 error. I use AT&T but I went to T-Mobile and all they did was remove the battery put it back in then said I cant help you so I went to AT&T and they said they didn’t no what to do but they looked up what I should do.

I spent the last few weeks trying to wipe the os but Java Loader and JL_cmder does not work they doth cannot connect to the device and the Application Loader doesn’t do anything it’ll see the handheld then when I hit next is says unknown. The Desktop Manager is also the newest version.

Also when I got the phone I didn’t get anything with it not even a battery and I don’t have a cd

Please help im running out of things to try and im ready to throw it at a wall PLEASE HELP ME
