How to enable root on my Device without using a computer I've been try my hardest these past couple months to figure out a way to root my Device without a computer(Got wet in April) and no success. The problem is , my Device is a BN Nook HD and Unknown Sources is blocked since software version 1.4.1 . So I can't use Kingroot etc. and It appears I can't do anything without a computer. 

Any Help or Advice would be largely appreciated.
Actually You don't need the Computer to Root using kingRoot just download KingRoot Apk from Open link to Download and Just network connection is enough to root the Device It's easy one click root and it works ;)
