I accidentally resetted my ti-89 titanium

Hi I wanted to delete this picture from my drawing application in my ti-89 titanium, but I was stupid enough to click on reset without knowing the what the final outcome would be. It turned out that it deleted everything but a couple applications. Now, I can't even graph normally, and I want all the applications back. Please HELP ME!!!!!

Hello,
Use the TIConnect software to connect the calculator to the computer.Then in the TIconnect main window you can drag and drop the applications you downloaded from education.ti.com. They will be transferred to the calculator.
I cannot understand why you cannot graph normally since the graphing is not an application, it is part of the OS.
While you are connected to the Internet and to the calculator, you may want to reinstall the OS directly from education.ti.com to your calculator
Hope it helps.
