Note 10.1 2014 edition stuck at Boot logo, backlight flashing SOLUTION

I had this exact issue, I searched the internet for hours and hours, and tried every combination of button pushes and tried getting into recovery mode but always got stuck at the first logo screen.  After trying just about everything I could think of, I stumbled onto the solution by trial and error and a little bit of logic.

I got my tablet working.  Here is how I did it.

I opened my Tablet up.   I used my fingernails to separate the chrome outside bezel from the screen just enough to slide a old credit card in and pry'ed the screen up, and continued all the way around twice until I was able to separate the the screen from the back.  I disconnected the battery, and then disconnected every ribbon cable visible, waited 30 secs and reconnected all but the LCD ribbon cable,   This cable is how the screen and backlight is connected to the tablet. I reconnected the battery and plugged the charger in, leaving the display ribbon cable unplugged.   I charged it for several hours using a 2.0A charger for my Galaxy Note 8 phone, and then I plugged the ribbon cable for the screen back in and it booted right up and works fine!

The reason why it was locking up is simple.

The battery was totally and completely discharged.  When this is the case it has a hard time taking a charge when the screen keeps booting up to display the charging icon and powers the backlight.   The voltage drops so low the processor fails, and Your frozen up until you disconnect the charger cord, then it dies.
