This 9.7-inch tablet launched almost 5 years ago loaded with webOS and never got an official Android update, but its hardware is capable to run Android 6.0.

I have marshmellow on my 2011 hp touchpad before my verizon note 4. How sad. Thanks for locking the bootloader verizon. You should be ashamed of yourselves. I'm ashamed I bought the phone although I like the size and functions. My hp touchpad never fails! Thankyou developers for working to keep the tp alive!
How's Android 6 on the tablet? Any major problems?
