how to fix my ipod when it has frozen with the apple at the front of it all it has is a black screen with and apple t the front of it ? yes
Since most android tablets are not water-resistant, they will probably have severe water damage. If it's not too late, take it to a technician but most probably they won't be able to fix it. I would suggest that you should not freeze your tablet. ;)
I have Samsung tablet screen flashing and cannot turn off
You don't. A repair shop usually can, but depending on the problem the fix might cost more than a new replacement machine.

How do you fix error code 489 on my android phone
You can fix your tablet by sending it to the company or by visiting a local repair shop.
Considering that you are trying to fix a bricked Android device, I would say you can fix it by flashing stock ROM back over the device !
If you know that it still has battery, try holding down the power switch for about 15-20 seconds to let it reset, and then be patient. Let it be for a while, and it should reboot and no longer be frozen.
