There is a progress bar while downloading and installing the OS
if it doesn't go away and you can't use your TI then you can re-install the OS
When you do re-install the OS just re-download a second copy from the Texas Instruments
website and use that. Do not unplug the calculator until you see the normal homescreen and everything is fully working again.

If you connect calculator to computer using Ti connect device explorer you might be able to see what files are on the calculator. I don't know if you downloaded from the web but, 3rd party programs and shells tent to miss up the calculator. This would able you to delete out possible problems which could be re installed later.

You have a older Ti89 /Ti83 APP or software on your calculator that you have to have a key, a proper serial number and a certificate in order to run on your calculator. Like my calculator has certificate #19 which allows me to operate a certain APP that is not issued any more. You need to get rid of that APP or software and update it with the new version. Obviously, you did not just download this recently from Ti89 \ Ti83 or Calculus Made Easy. This should give you a clue to what you did wrong. I don't think Nils at Calculus Made Easy or Ti89 \ Ti83 will give you a certificate but, they will help you with your software needs. K24674 instruction to you on how to reinstall the OS v2.09 for Ti89 is correct. Just don't try reinstalling the APP's or software that you had on the ti89 \ Ti83. Go to the Ti89 \ Ti83 APP's and programming sites and download and install the new updated versions of those APP's and software for your calculator.
