Question about Texas Instruments TI-Nspire Graphic Calculator

Sorry, answer was posted as a clarification request.
Here it is from the horse's mouth (TI Knowledge base)
For the TI-83 Plus Family, TI-84 Plus Family:
Caution: The resets described in these troubleshooting steps will cause a lossof applications, programs and data. If at all possible please create a backup using TI Connect™ first.
Reinstalling the OS fot the TI84Plus
How do I correct the Error Waiting...Please Install Calculator SoftwareNow message on my TI-83 Plus family or TI-84 Plus family calculator?
If an operating system (OS) update fails or is interrupted, the calculator will be in an inoperable state with the message Waiting...Please install calculator software now.The most common cause of a transfer being interrupted is updating theoperating system on a calculator with low batteries. Users will need touse the TI Connectivity cable and the TI Connect software to send theoperating system to the calculator. Make sure to have the latestversion of TI Connect installed on the computer.
In order to install the software please follow these steps:
1. Connect the TI Connectivity cable between the computer and the calculator.
2. Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader
3. Follow the on-screen directions to reinstall the calculator's OS.
Ifthe message "Error! Press any key to turn unit off. Then turn unit backon." appears on the graphing calculator, quickly, remove one batteryfrom the calculator and reinstall it while the transfer is taking place.
Hope it helps.

SOURCE: I downgraded my TI-Nspire's OS
I had this same problem myself and I had to look everywhere to find a solution. You will have to remove the current OS from your device. Heres how.
I couldnt use option 2 for some reason and had to use option 4 (complete format, luckily I had backed the files up earlier) but once it was reformatted the device showed up in the software and told me to update the OS. From here you just install the latest OS as you would normally.
The problem with what you and I did is that previous OS versions (1.7 in my case) dont support the keypad, you may be able to use the older version with a different keypad but I'm not sure.
Anyway, I hope you can fix it, good luck.
