Hmmmm.... I will have to go through the KF HDX source, but if this exploit exists & it may very well considering it wasn't even fixed by Google until 4.4.2, the ASEC exploit should work just fine on the HDX.
Some interesting info here: http://blog.cassidiancybersecurity.c...old-local-root
Basically the way ASEC exploit works, you can redirect a partition mount to ANYTHING, as long as it is an existing directory & there is an existing symbolic link to the directory. Interesting, even if it is a very old exploit, & very possibly something much easier to accomplish root with than some of the things I have played with, including SED...

Hey, guys, I made the suggestion to contact jcase again a few days ago. PLEASE do NOT
contact him regarding exploits right now. He is taking a break from this stuff & I hadn't bothered to check with him, or to check his current status.
If I feel like I am onto something, or if anyone else does, please let me know & I can get the idea or possible exploit to someone else. Jcase has done a lot for the XDA community, so give him his well deserved break.
