ok, so a friend of mine has a TI-83 plus…the other day, it went haywire and turned off…it wouldn't turn back on, so i pulled the battery out, held DEL and put the battery back in…it said "Install Calculator Software…", so i hooked it up to my calculator and did 2nd LNK SendOS…after a few minutes, my calc shut off, while the other still said "Receiving OS 0%"…it remained like this form 20 minutes, never changing. i also tried hooking it up to my computer to install an operating system, but the percentage remained at 0%…
i have tried everything i know, can anyone PLEASE help?
i don't know how the OS could have gotten erased…
thank in advance
