TI Calculators / Need Help With a Possible Bricked TI-84+CSE
« on: May 28, 2022, 04:54:34 pm »
I recently got a (pre-owned) TI-84 Plus Color Silver Edition, and it worked just fine for the next two days. Then, I thought it would be cool to install an alternate os that has more tools, so I looked into KnightOS. I got the correct os file for my specific calculator and uploaded the file, but it failed somewhere in the middle (i was not in the room when it failed). I decided to re-upload the old os, so I got the old os file from TI-Planet, and plugged my calculator into the computer, but it didn't recognize it. I tried 3 different mini-usb cables, I tried removing the battery for a while to drain it, and I tried a bunch of key+reset button combos, but none of it worked. When I turn it on, it says "Waiting... Please install operating system now," and when I plug it into my computer, press on, or wait about 1 minute, it says "ERROR! Press any key to turn unit OFF. Then turn unit back ON." I press a button, and the calculator turns off, and when I turn it back on, it just says "Waiting..." again, like nothing ever happened. All the while it is unrecognized by the TI-Connect CE Software, and the old TI-Connect software. I have suspicions of it being permanently bricked due to a corrupted os, but I have only dabbled in this kind of thing. The KnightOS file I used is attached to the post. Please help!
