The Demo Kindle Fire Model Number 3HT7G is completely locked down. It is not possible to remove the Demo, reset the Kindle or Flash new Firmware using a Backup and Restore Utility like Kindle Fire First Aide. The Development Team of Kindle Fire First Aide is working on a procedure to reset these Kindles but the procedure will involve opening the Kindle which Voids the Warranty. Until we develop this procedure you are locked out. Sorry, I wish I had better news. Best regards, Chris Bryant - Prokennexusa at XDA Developers

When you plug it in, does it display that it's charging? If not, it might be a problem with the charger.
