How Do I Fix My Ti-89 Titanium Stuck on Waiting to Receive... Screen?

[Fizix]

I was downloading a new OS onto my Titanium the other day and after it downloaded about 25%, it gave me some error and canceled downloading. Now, my Ti-89 is stuck in a "Waiting to receive..." screen. Left+Right+2nd+On doesn't work, and neither does taking out the batteries and putting them back in. What should I do?

Thank you.

By the way, this is my first post here. I can't wait to become a part of the community.

I'm a high school freshman, so I'm stickin' around for a while.

I don't know about the 89's, but on the 83's if you take out the batteries, and the backup battery, it resets the memory. You could try that if the 89 has a backup battery. Check your instruction manual to see if it has one, otherwise you could try emailing Texas-Instruments customer service/tech support.

the TI89 has a backup battery, you should be able to take it out by lifting the panel for the regular batteries, its right above them. you'll need to unscrew it with a small phillips head screw driver.

how did you manage to get interested in quantum mechanics, relativity, and abstract algebra as a freshman in high school? most students don't get interested in those subjects as freshmen in college

came to this forum to unstick my ti-89 and combined a few methods. hit keys in this order. 2nd, <, >, ON. should reset. did on mine when i accidentally hit approximate on an infinite function.

Hello there! As a fellow scientist, I can understand the frustration of encountering technical difficulties with our equipment. In this case, it seems like your Ti-89 Titanium is stuck in a "Waiting to receive..." screen after a failed attempt at downloading a new OS.

Firstly, I would suggest trying a hard reset of the calculator by removing all the batteries and leaving it without power for a few minutes before reinserting them. If this does not work, there may be a problem with the OS itself or the connection between the calculator and the computer.

I would recommend contacting the manufacturer or seeking assistance from a professional technician who is knowledgeable about the Ti-89 Titanium. They may be able to provide specific instructions or even fix the issue for you. In the meantime, it may also be helpful to check online forums or communities to see if others have encountered similar issues and found solutions.

As for your interests in philosophy, quantum mechanics, astrophysics, and other scientific fields, I'm sure you will find many like-minded individuals here in the community. I look forward to seeing your contributions and discussions in the future. Welcome aboard!
