Well guys, i'm sad to report that even with the Virtual Calculator feature enabled on Omnicalc, the OS still blocks it from being used.
Maybe..... we'll get an Omnicalc upgrade that allows us to beat the OS.

Yeah, I just updated to 2.40 and the lockout feature sucks. If anyone knows it's there they can lock you out until you find a friend to send you a file. Also, I heard it was on 2.30 also, but I remeber trying it out and it did not work. If anyone still has 2.30 could you confirm this? Also, for 2.30 users I remember if you pressed prgm twice you would get a secret menu or something. On 2.40 this is not there.
One last question: Is there a place they still give out v. 2.30?

I am a little mad because i tried to update to 2.40 or whatever and when it was being set it erased my old os but wouldn't send the new one and now my calc only says "please install operating system now" what should i do

what exeactly is an os and what does it do for my calc

Hello i just bough my 1st TI, its a TI 84 plus silver, i started downloading the 2.41 version and i got scared if i was downloading a virus cause it deleted my calc operative system so i disconected the cable befor it finished. Now i dont have any operative system.
Any one knows a way to get an operative system back on it? i tryed downloading to the calc the latest version but i cant pass the 33% (thats the % where i disconnected befor). Sry to bother but im getting desperate
