[suicidal_sara06]

Right now screen shows the Android robot on his back with a door open and the background says no commend and in yellow letters says Recovery system v4.2.41 Now send the package you want to apply to the device with "adb sideload <filename>"...

Am not sure what it wants me to do and am not sure where to go if i have to download a file to fix it. Please help!!!!

Welcome to Android Central! As long as the tablet isn't connected to a computer via USB and in the process of downloading a firmware file, you can force a shutdown by pressing and holding the Power button for 10-15 seconds. Then power on normally.
