    I did it as you said Mike, and the calculator is wating to receive the OS but the PC and the TI-Connect don't detect the calculator. It is the right cable.

    I used the silver link cable. If you have another TI calculator make sure your using the correct USB port to verify connectivity. Then when it asks for the operating system go to the TI device explorer and select Tools and then Ti OS downloader and select the OS for the calculator that you have, TI 89 Titanium and then select the cable you have and then click start download. The calculator may not be able to recognize that your attached because the memory is locked up. But I did the download from there and I was able to restore my calc from the ER Throw error after the factory reset didn't work. You sound to have a simular problem. Update me what happens.

    When the calc says waiting for OS its expecting the OS file to come through the cable and may not have other functionality regarding connectivity.

    Make sure your using the correct USB port on your computer. I have another TI 89 Titanium and I hooked that up prior to trying to restore my calc to verify which usb port I was using on the computer as it says USB1 USB2? By holding down the key your trying to initiat an interrrupt when the calc is first turned on so it doesn't get to the memory lock up. Try turning on with the apps button pressed in with the cable attached to the computer and without being attached to the computer.

    Does it say that its not detected on the computer? Could you just force to send the operating system? Or do you get an error when you send the operating system?

    But my computer doesn't recognize my calculator, TI Connect can't do it either. I have the Original cable and I have tried with other calculator from a friend (same model) and my PC detects his calculator.

  • Michael Schaffter

    OK, when first turning on the calc, you only have a limited period of time before the memory locks up. First try telling the computer to detect the calc and then turn the calc on, and see if it detects it, if that doesn't work, then tell the computer to detect the calc and then do the reset while the calc is plugged in. You may only have a few seconds before the memory on the calc locks up.Well it may not be able to detect the calculator because it would need an operating system to be loaded from the flashed bios in the calc. Just try resending the firmware agian to the calc.

  • Michael Schaffter

    And specifically specify for the computer to look at USB port what ever so the computer is not searching wrong ports. Make sure the small button cell battery is removed at this time because if its not your not reallly doing a reset. After the calc works then put the small button cell battery back in, and make sure the button cell is good or new.

  • Michael Schaffter
    Michael Schaffter Sep 02, 2013

    Or try plugging in your friends calc and then have the computer recognize the calc and then select the operating system for the calc to update and then quickly unplug your friends calc and plug in yours just before sending the operating system.

    Are you using the silver link cable? Maybe by using the silver link cable the computer thinks it is connected to the calc, and using a nonsilver like cable the connection to the calc is not easily recognizable. Did you try connecting two calculators together with a cable?

Remove the small memory battery, and then remove one of the four AAA batteries, then while holding down the APPS button reinstall the AAA battery and then it should say waiting to recieve operating system then hook it up to your computer with the silver connect cable and then on the computer send the operating system to the TI89 Titanium, and wait for it to install completely and it should work.

I have the same problem (TI-89 titanium)
1) 2nd+left+right+>on lets me restart the calculator to app menu but is frozen.
2) remove battery>hold "APPS">reinstall battery> "waiting to receive"
3) no connection to PC. I've tried latest version TI connect, restarting computer, reinstalling TI Connect software + restarting PC, new cables, and even different usb ports. I even tried different computers, Windows 7, Windows 10, and MAC with TI connect 4.0. But the problem is TI-89 calculator is not showing up on the device manage USB ports....

Lastly) it would be a waste to discard the calculator when it seems mechanically functional and responsing to the 2nd+left+right+on and battery+APPS procedures, but locked in software...

still looking for a fix.

SOURCE: I received this solution, but at the end the

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.

My TI-89 Titanium's screen froze. Well actually, the cursor kept blinking but none of the buttons worked. I got it to restart using the (-) and ) button trick, but rather than going back to normal it went...


Hi kelsers,

You need to re-install your calculator's OS. After this process your Ti 89 Titanium will operate properly. If you do the process below make sure you use new batteries.

Warning!!! If you do this procedure make sure that your computer and, calculator are connect. Use Ti Connect software and, make sure you can install the OS on the calculator without any interruption. At any time even at the very beginning of this process, if your computer or, calculator gets interrupted or you have a power failure during the installation of the OS, your calculator will be destroyed. So not attempt this procedure during a thunder storm.


You can use the Ti OS Downloader but, you will have no idea what OS is stored by the Ti OS Downloader. So, I suggest following my instructions and, installing the newest Ti 89 Titanium OS 3.10v.

Procedure to installing the newest Ti 89 Titanium OS 3.10v.

You can also get the latest copy of Ti 89 Titanium OS 3.10v by going to the Texas Instruments web site. You can get to that site instantly by clicking, "Ti 89 Titanium OS 3.10v." Once your at the Ti site click the Download Item, Ti 89 Titanium OS 3.10v. Next you can login or, click "continue as guest". I'd would click the "continue as guest". Once you have click, "continue as guest" the Ti 89 Titanium OS 3.10v. will download to you. Click, "SAVE". And then a folder will pop up. It is probably a folder that you download too. If so, you may want to change it and, "Save as" to this folder, "My Documents \ My TI Data \ Downloads". You can also go back and, download the Ti 89 Titanium guidebook too, if needed.

Link your computer and calculator with the USB cable or, Direct Black Link cable that came with the calculator.

Remove one of the AAA batteries. Press and hold the [APPS] key, and while holding the [APPS] key, replace the battery and turn the unit on. On the older TI-89 you should see "Press I to install code...", and you should press the [9] key to continue. But, on your Ti 89 titanium it should say, "Waiting to receive..." or, "Waiting to received OS...". Now you need to follow the instructions in the paragraph below to restore the calculator's operating system.

Next, drag the Ti 89 Titanium OS 3.10v. that you copied earlier to "My Documents \ My TI Data \ Downloads" out of that folder and, drop it in the "Ti Connect" icon on the desktop. Next the OS Downloader Warning will pop-up. Click, "OK" to continue and, the new OS will begin to install. The Ti Device window should pop up and, click on to the port where your Ti 89 Titanium is located, USB1 cable or Direct Black COM1. Just click, "Select" and, the OS will continue to download. Upon completion the newest Ti 89 Titanium OS 3.01v. will be installed.

Ti 89 Titanium


The only option or keys that will work is the ENTER key and the arrow keys. Try to get your arrow key to work by arrowing down and hit enter hopefully change you to something different.
Next, if at all possible can you hit the MODE key or get into the mode. If you get into the MODE select F3 and then arrow down twice or all the way to the bottom and at APPS Desktop select 1:OFF and then hit the ENTER key. Next, What I really think you need to do is reinstall the Ti 89 OS software. To do so you would need to connect to your computer or another Ti 89 Titanium to your Ti 89 Titanium. If you have Ti connect computer software (from the Ti site) connected to your Ti 89 Titanium it might help you more in troubleshooting any further problems too. You might be able to delete corrupt files that would free your calculator up and start running better.

TI-89 Won't Turn On


Please don't get your hopes up, but perhaps something in the following few suggestions will work:

For the TI-89 Family, TI-92 Family, and Voyage™ 200:
  1. Adjust the contrast by pressing and releasing the Diamond Key key followed by pressing and releasing the [+] key; repeat as necessary. To adjust or lighten the display, use the [-] key.
  2. Users of the TI-89 Titanium or Voyage 200 should see the following case before performing the following reset procedure to prevent the loss of valuable Apps.

TI-89 Titanium users should see "Waiting to receive..." or "Waiting to received OS...". You will need to restore the calculator's operating system.
To reinstall the Calculator's operating system, take a look at the following TI site.

http://epsstore.ti.com/OA_HTML/csksxvm.jsp?nSetNumber=12089

I would hunt around on the TI knowledge base to see if there are some more useful suggestions if nothing above works. If I find any more info that could be useful I will post it.
