Hi! Your device seems to be in between the No Command Error and Bootlooping. The No Command Error occurs when your device is carrying out a reset, restart, a certain line of code, or a system update, and somehow failed to do so, or was denied the needed access. This means that a near-fatal error occurs, and since its to-do function was terminated, your device doesn't know what to do. Usually, it will restart itself, but in some cases, that's what it was trying to do, amd failed, so your device is arguing by itself over what to do. But never fear! There is a fix. Instead of a soft reset, we're gonna force our way into Recovery. If your device is bricked, in No Command, or is bootlooping, you can put your device in Recovery Mode to help you out of this. The following is instructions and tips on how to enter and reboot RM (Recovery Mode.) Remember, I am assuming you have the Android version of the tablet. If you have it in Windows OS, this will not work. Now, to enter recovery mode, you have to hold down a combination of keys. Hold down Power + Volume Up/Down/Home Key for about 5-30 seconds. (I'm not sure about what the combo for the hard reset is, so you'll have to figure it out on your own. But there aren't many keys to hold down, so it really shouldn't take long to figure out the combination. Whence you figure it out, sometimes you will get the No Command error once again before. If this happens, don't freak out. Just press/hold the power key, or the combo you used to enter Recovery. Then, you will likely enter RM. The Recovery Mode page is a barren page, with all but the No Command error picture in the background, and some text and and a menu. The title will read "Android System Recovery Mode", or something along those lines. Use the volume keys to navigate, and the power to select. Using that, select restart, or reboot. Your device should restart normally, with NO data lost! Voìla! Your device is fixed! Now, if this happens again, Richard is correct. You will have to factory reset your device. Use the exact same step, but instead, select "factory reset." Have a good day.
