CALCULATOR hacking ( to test every button is working or not )

Yes ! guys today we wont hack computers or mobiles today on cybergo Labs our patient is a

CALCULATOR a scientific one indeed ( this hack will almost work on every CASIO model )

 start your calculator by just pressing ON , 

now

PRESS SHIFT , 7 and ON button altogether (what ????)

Let me explain press shift (press it don’t leave the button )

Then press 7 don’t leave that too (now u r pressing 2 buttons altogether )

Then press ON

Wow a strange screen appeared ---

Now keep on pressing SHIFT BUTTON

You will see the following screens

now at last u will get a screen with 0 (zero )

now its time to test your button

START from SHIFT button if the button is working it will display 1 if next button ALPHA is working then it will display 2 …. Now don’t press ON until u have tested all buttons

There are 49 buttons to test. But you have to follow a order like pressing 7 ,8 ,9 then 4 ,5, 6 until your screen displays 49 .. press ON when your screen displays 49 which denotes your all buttons are working

Now we have successfully hacked a calculator…..
