    Default HDMI output via MHL with no restrictions

    I'm trying to find a way around HDMI output restrictions. Certain video streaming apps will not load with an MHL cable connected (example-starz play, the Optimum App, the Xfinity App).

    I tried flashing CM10 just but didn't work (plus HDMI output was pretty much broken). I'm looking for either a custom rom that "hides" the fact that I have an MHL cable connected, and will just mirror my screen regardless, or some sort of hack. I've been doing a lot of googling, and so far I've found an app called HDMI virtual switch (Hdmi Virtual Switch) which didn't work for me, and a lot of talk about modifying the file "/sys/devices/virtual/switch/hdmi/state" to change it to a 0 instead of a 1 (when an MHL wire is connected, this file has a single "1" in it, when you unplug it, it has a single "0" so I think apps are checking this file to see if I have an MHL wire connected) every time I save the file with a root explorer type app, it just get's set back to "1" again while the cable is connected. I'm desperate! I'll flash anything to get this to work.

    Thanks in advance

    Are you mounting the system with R/W permission in the file explorer app?

    Yup, it lets me save it, but then It looks like it gets overwritten immediately. I even see a modification date at the same time or seconds after I modify it.

    I was considering changing the value to 0, then taking away permissions to write to the file completely, not sure if the device will crash or not when plugging in MHL, I'll have a full nandroid backup before attempting that one!

    Well that didn't work, seems I can't take away rights from the system for updating that file, still looking for a way around this =/

    I have one of those, only works for a few apps though, Netflix, youtube, Hulu. There was a hack for chromecast called allcast that allowed you to stream anything, but they shut that down. I think I need to learn how to recompile the OS myself, I found a java class online that had the methods for setting the HDMI state, if I could just modify that class file and recompile whatever packages it may be in, It just might work....of course I've never done any android development so I first have to learn to do so

    Do you have the version of chromecast that you can root?

    I'm late with this but I'm having the same issues with the HDMI output. Specifically the TNT app. Was there any progress on this?
