I have a Ti-84 plus silver.  I was kinda annoyed with something, so then I tried restalling the OS (2.43).  The OS didn't install correctly because the batteries were too old.  I put in new batteries, reinstalled the OS, but now TI Connect says it's a Ti-83, and also whenever I try to launch an app, it will turn off, and then you can't keep it on anymore unless you ram clear (hold Clear, press ON).

Any solutions?  Thanks.
