Thank you for contacting Texas Instruments. But because my daughters is boot looping at 50% I cant get to this menu.

I thought maybe I was doing it wrong so my daughter borrowed a friends calc, it gets to about 65-70% then the maintenance menu appears. This does not work, as the boot loader is only ever getting to 50% My next thought was that obviously the boot loader or OS is corrupt, so according to docs, you need to enter the maintenance menu using DOC /EE /ENTER and reset button on the back. Battery is now at 100%īut either resetting with rear button or removing battery still makes it boot loop. I have looked online and can get into Diagnostic mode using ESC /MENU /- and battery tests etc are all ok.

Now when you turn it on the progress bar only gets to 50% across and boot loops.

My daughter has brought me her Ti NSpire CX CAS Calculator yesterday with a problem.Īpparently it wasn’t charging the battery correctly, and went flat (I think it was a damaged USB cable that caused it not to charge)Īnyway.
