Press and hold Volume up and Power button at the same time until you boot into the Android system recovery.... Choose Wipe data/Factory Reset with your volume keys and then press the power button to confirm.

This is a generic factory reset for most tablets:

1. Power off your Tablet.
2. Press and hold Volume up and Power button at the same time until you boot into the Android system recovery. ...
3. Choose Wipe data/Factory Reset with your volume keys and then press the power button to confirm.

Well done so far.
Probably, the button or key you are using to action your command for factory reset isn't correct/appropriate.

Try a few other options.
Please note that
Up/down movement-------a button/key does this

Yes/select----------another key/button does this

Give the entire process another go at factory reset please. It should work.
Best of luck.
Post a feedback asap, please

You will likely have to reset your tablet to it's factory settings using the key sequence.. it'll mean you'll have to re-load your data and programs but you'll have your tablet back. Been there more than once... Oh well.. here's the procedure:

Press both the volume up key and the power button key to turn the tablet off completely. Once it's off, press down the power button and the volume key together. Release the power key and hold the volume up key until the "Factory Reset Menu" appears. It looks kind of like a robot with it's chest hatch open. Use your volume up and down buttons to move the selection to "Factory Reset" and press the power button to select it. The tablet will reset itself and you'll be back to a brand new tablet.

Then wait for the One Key Recovery button. Then Press the One Key Recovery option once it loads. Then press restore to factory default. Then click next and then click start.

Hi,
Not every function on the TI83Plus calculator has a dedicated key, or is accessible through a key sequence. Among the keyless function is the factorial function.

To access the factorial function

1. Through the catalog of commands: press [2nd][0] (CATALOG) and scroll Up till you reach the exclamation mark !
2. Press [MATH]. Use right arrow to highlight PRB menu. The factorial function is the 4th in the list.

Syntax

Type the number and use one of the foregoing access methods to echo the exclamation mark on the home screen and press ENTER.
Ex: 12! =479001600

The largest number that you can use with the factorial is 69.

Hope it helps.
