If you mean it shuts down then the battery is most likely failing, if you mean the programs stop running then try doing a memory dump, get rid of all the old data files you can. Transferring as much data to a SD memory card helps as well

it's always better to turn off, any paired device when you dont use it.

Unless the manufacturer releases an update you would have to root the tablet to change the android version .

Try another sd card to see if the problem lies with your original card or the tablet itself.

CONTACT THE MANUFACTURER THROUGH THEI SUPPORT PAGE OF THEIR WEBSITE AND ASK IF THEY CAN HELP YOU, THEY MAY BE ABLE TO PROVIDE YOU WITH THE PART

On the AXS what does the reset button under the headphone jack on the back...

How is it preventing you from downloading. What is the operating system....android? Some devices will not recognise memory cards that are incompatible because they are too big or the wrong type., are you able to load anything on the card from the tablet. please add more detail and resubmit

This is how to remove the demo mode from the Trio AXS tablets:

1. Start tablet. When demo mode starts, click the menu icon and find the CALCULATOR app.
2. In CALCULATOR, type the following "!(364)!" (no quotes). This will put you in admin mode immediately. Click CONTINUE.
3. Enter the password: "Adm!nTr10!" (no quotes, mind the case). Now you have a list of options.
4. Un-check all the BLOCKED APPS.
5. Un-check all the items under DEVICE MANAGEMENT.
6. Exit and reboot.

you're done.
