What kind of an error is this? It happened after I executed Calcsys. I tried to press ON, that didn't work. I tried to remove a battery. That also did not work. I tried to drain of it from power completly. That STILL did not work. I cannot scroll options and now it is stuck at a screen with a bunch of characters, ASCII chars 3x3 black pixel squares, and other stuff. I think my TI-84 Plus is completely bricked. Nothing will do. I called TI about this, and emailed them, and they cannot solve the problem. And y warranty just expired yesterday, so I am so screwed. None of my programs are archived or grouped.
