The only mods done to this stock note 2 from Sprint are: rooted and disabled KNOX. I initially had a bt connectivity problem, where after running aru and attempting to connect it would just show disconnected after about 10 seconds.
I somehow got this solved after multiple reboots and permission fixes through rom manager. I was also having the same problem you are having now with aru giving me the proverbial finger. The fix permission and reboots also solved this problem.
The problem I am having now, is the touch functionality is not working on my HU. The bt stays connected, rotation works, and everything mirrors smooth, but I have to use my actual phone. It let me calibrate the screen during the initial setup, but when I double tap mode the only thing that changes is the toolbar to the left goes away. Touching the display on HDMI mode only activates the HUs normal functionality (down arrow in top left corner to change input, etc.)
Have you or anyone else had this problem? Do you have any ideas on what might be causing this? I've been at this for some time now an getting pretty damn frustrated.
Thanks in advance!
Huzzah I figured it out!!
Okay here is the issue. My phone already had AppUnchained running in the background in a sleep function. See that little icon next to my phone missed called? Thats the BT function waiting in AppRadio. This means that as I hooked up my phone. AppRadioUnchaine was already running.
Notice how my functions on the right side are greyed out? That's when you get the Red Finger of X.
Here is my Screen Mirroring but look.....Greyed out menu on the left Meaning again Red Finger of X
Here it is running in the background on my phone as well..in the background
Here is what I did :-
I put it in Hibernate using Greenify.
Then I fire up ARU and hit the Home Button and looky here, My HDMI is lit up and my APPS is hilighted now meaning it can run Apps off the phone
I Hit Apps in the Head Unit and volia No Red Finger and I know that because the Left menus is now available.
I exit the App on the HU touchscreen. And Voila full touch screen controlling my phone. You know you will NOT get the Red Finger of X because the Left Menu is now touchable.
Any question ask away. But I think this is the issue. APU not closing properly. Seems that the HU Likes it only on a fresh new instance of ARUnchained. otherwise Red Finger of X. Remember , You might have to unplug your phone a couple of times for ARUnchained to start up and detect it. It's something to do with the MHL Cables.
