Rooting HP Slate 21 all in one with built in Android Jelly bean 4.2.2 Any ideas on how to root a HP Slate 21 all in one with Android Jelly bean 4.2.2? I am going crazy trying to find a solution for this.
I'm using a to a USB cable that works.
Adb works
And flash boot
There is a adb fingerprint for drivers at hp3 forum.

Unlocking boot loader also no problem.
Root don't work with the normal stuff,
And the Chinese program's also failed.
Wait for a tegra4 like version hope will come soon,
Think its hacked until Christmas.
