I turned on my Ti Voyage 200 after like a month of no use (and no batteries on) and a message poped up saying "illegal instructions" I used the [2ND]+[HAND]+[ON] reset and it didn't worked out then I went to try and reinstall the OS and as soon as it says "waiting to receive.." I hit the "start download" button on the Ti Connect app and as soon as I do that a message on the Voyage 200 pops up that says "Cannot back up cert memory" and I can't reinstall the OS.
I really need help.
