i accidently deleted the applications off my ti-83 plus calculator. are there any ways to restore them? thanks

Answer 1

Hi,
I am not aware of a way to recover deleted APPS. They are stored in flash memory, and I believe that the data is erased rather than just deleting it from an index. But if you have backed up your calculator to a computer --my guess is that you haven't -- you can restore everything.
Otherwise, it's a fairly simple process to transfer APPS from a friend's calculator to yours if you have or can locate one of those unit-to-unit cables. Here's how to do it:
I will assume that both calculators are TI-83 Plus:
a) Turn both calculators off and plug in the unit-to-unit cable for both calculators.
b) Turn on both calculators and press 2nd, LINK on both. Cursor over to
RECEIVE on the receive calculator, the calculator that you're transferring the
program to.
c) Press ENTER on the receive calculator. The word "Waiting" should appear.
d) On the sending calculator, cursor down to APPS and press ENTER.
e) Cursor down to the applications you want to transfer and press ENTER. The
application(s) that you selected will be marked with a square "dot."
f) Cursor over to TRANSMIT press ENTER.
g) If everything is connected satisfactorily, transmission of the program should
start. Otherwise, you'll get a transmit error after a few seconds.

Hope this helps.
