Trio stealth-8 i bought my daughter a trio stealth -8 for christmas but now when i turn it on it doesn't do anything , all i can do is power it on and off , and it has a message on the screen that says @9DUAL CORE

Perhaps the HARD RESET PROCESS can help you, Merrill. I've posted my suggestion as to how it's done HERE. ( http://www.fixya.com/support/t25341481-trio_stealth_new_when_power_goes ) , so you may findt that information useful.
I've had good success with HARD RESETTING when trying to correct errors like forgotten password, or forgotten lock-patterns. However, I've had a Trio Stealth G2 that displayed the SAME problem as yours, Merrill, and it would NOT respond to ANY attempts at resetting. I tried every combination I could : pressing volume down (-) and power; volume UP (+) and power; volume UP & DOWN (+ AND -) and power. It refused to boot. But since the case and the screens were in great shape, I went on Ebay and bought a Trio with a cracked screen, swapped the motherboard from THAT tablet and it worked perfectly.
Final caution, though: ask the Ebay seller to guareantee the physical condition of the ports and other controls on the unit before you buy it. Remember you need a working motherboard.
Best of luck to you, Merrill!

your tablet losses all data. go to the nearest cellphone tech. for the reprogramming.

Its a common problem with tablets and not easy to fix.
Your tablet has a corrupt os and is caught in a boot loop.

There are fixes but not easy for a beginner.

Boot into recovery mode by pressing the power button and holding the down volume button in then select restore tablet from the recovery menu.

on the box also there should be a number on the back of the unit.

My daughters tablet did the same thing. After we had it for about 2 weeks. Called Trio tech support. Ended up having to send it to them and they sent me a new one.

WHAT I NEED TO DO IT WANT DO ANYTHING FROM HERE

try your charger with some other device
if its working then there is a problem with your charging ic
or processor
go to othorize service centre

all that shows is trio stealth G2 when turned on it freezes I tried the reset button

Check for a bad battery, charger in that order.
