Hello!

I'm a complete idiot when it comes to these kinds of things so I'll do my best to describe what I did.

The other day I purchased a TI-89 to get ready for my upcoming semester at school. I DL'd TI Connect, having no trouble connecting to my PC and updated to AMS 4.00 and HW 3.10. I hope I have that right. A friend of mine told me if I install a program called PreOS I could install many programs... and of course games! Here's where the problem kicks in.

I downloaded a zip named pedrom-0.82, among other files. I moved the file PedroM-89i.89u to the calc and ran it. THINKING it was the right program. After installing it I was, and still am, presented with what seems to be a dos prompt. I had no idea what to do next. It looked completely wrong. So I just turned the calc off and reconnected it to my PC. Now my PC and TI-Connect both won't recognize it! I just used it like 2min ago! What did I do wrong? Did I ruin it? Is there anything I can do so I can do it right next time? I tried removing all the batteries and I tried the different methods of holding certain keys down.

Thank you guys for your help!

When you say you removed all of the batteries, did that include the small, circular lithium battery? If it is still in, your calculator will restore to its past state every time you turn it on.

Oh sorry, my bad. Yes I did remove all the batteries. The 4 AAA and the lithium battery under the screw. I left them out over night after I posted. No progress has been made. I put the batteries back in and its still showing

It looks like you installed a separate operating system. You'll want to reinstall TI's latest OS using software that PedroM recognizes. PedroM doesn't support TI Connect, but it should work with TiLP. Why not try installing TI's operating system that way?
