Hi, i was having the same problem.
I wanted to upgrade my Ti 89 titanium OS, so i run the Upgrade check inside the Ti Connect App. It downloaded the OS to a folder. Then i tryed to upgrade with that OS, and in the 99% it fails.
I guess something was wronge since the progress bar in the windows downloader app was out of sync with the calculator percentage. I downloaded myself the OS from Ti, and removed all batteries (including the backup). After plugin in the batteries again, i started the Os downloading with the new file, and the progress was perfectly synced with the calculator percentage.
it finished flawleslly and now it is working :)
please excuse my english, im spanish

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  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.
