Start with tablet off. Hold power and volume up. You should boot into safe/repair mode. Try some of the options in there to get your tablet going again.

Do a hard reset, press and hold the +vol button, then the power button, wait about 20 seconds both buttons held till the start android screen appears. Hope that helps

RTM - Read The Manual.

Your manual says if you can boot into windows then click Start/All Programs/Samsung/Samsung Recovery Solution

If you cannot boot into windows when you turn the computer on hit the F4 key.

ANDROID Tablet Freezes at Android startup screen

For Superpad VI - 10.1" Android Version 4.03, this worked for me!

1. Press & hold START button
2. When "VIMICRO" appears, Then Press & Hold the MENU button
3. The Android System Recovery <3e> Menu should appear
4. Scroll down using the Volume Key to "wipe data/factory reset"
5. Press HOME Button
6. Scroll down to "Yes - delete all user data"
7. Press the HOME Button
At this point the system will do a recovery and hard start, and will be on "reboot system now
8.Press the HOME Button
Your system should reboot normally, but you will need to enter all new data, as it has been wiped clean.

your saved game data is corrupted.

If the problem is only with the Black Ops game it could mean that the the game paly data is corrupt. Start by deleting the saved game data and the file data for the Black Ops game and if that doesn't work try doing a system restore. NOTE: A system restore will delete all other game data. I recommend backing up your system onto a usb flash drive.

samsung kies software which can be downloaded in samsung download site

my samsung gte 2120 wont start all it does is showing the welcome screen and restarts again

Sounds like you need an inverter board which is the power supply for the screen lights. I tried to look up the part but samsung dosen't have a service diagram posted for it yet. Since it is so new you may want to find a samsung authorized service center because if the part is not available yet Samsung will have to solve the problem.
