Well, after I take out a battery, and push del and put it back in. It says "Waiting... Please install operating system now", and I connect to ti-connect and that says "ti-84+se detected but couldn't get status" so then I send the Os to the calc, But then a popup comes on screen saying that there was a problem with the ti-connect, but the Os starts to send anyways, it really really slowly creeps to 100% (takes about 1/2 hour) and so the calc now has a new Os. But when I turn it on it looks like the picture below (it is on just nothing shows up) and none of the keys work.I know this picture is big but I will delete this post after (p2) sees it. The first one is the Os screen the second is what the calc screen looks like after an Os update.
