    I thought I had the disabling ota on this sprint SPH-L720T Samsung s4, but it seems I don't.
    I've been reading and found to disable, delete or rename the file name SDM.apk and the file was supposed to be in the system/app folder, but I can't find that file.


    So, a couple of questions....
    1: what file or files do I need to freeze, rename, delete to disable ota updates?

    2: I will be rooted, but that's it. I am rooting with towwlroot so as not to trip Knox. I was told a xposed module would disable ota but my question is to use xposed do you have to install it via a custom recovery? If so that not an option because I do not want to trip Knox.
    Also does it trip Knox at all by installing or using it? ie: modify the boot loader or anything.

    I'd be much more comfortable doing the first way honestly, so if way #1 is possible I'd rather do that way, just need to know what files and where they are located.
    If anyone can help I'd be most appreciative.

    I find it hard to believe that no one knows how to disable the ota.

    Guess I'll bump, in hopes someone knows.

    That's for the galaxy note 2, not the phone I'm after. It's not a matter of one way works for every device.

    I have read multiple ways for the s4 and it really depends on the make or model, because not all the methods work for each and every s4 out there.

    This is a prime example of just that.....For the methods I've seen it says to disable, freeze, rename a file and that file is nowhere on my phone. I was informed that is a file on the att model of the s4.
    That's why I specified the model number and carrier and phone.

    So sticking to this specified phone, does anyone know a way to disable the ota ( on this phone)

    If you have a rooted Samsung Galaxy S4 you can delete these two files ‘fota.client.apk’ and ‘fwupgrade.apk’ with root explorer in system/apps. If *you*get an error that “filesystem is write protected,*just make sure while using root explorer click on R/W button at the top. If you have installed *an stock rooted odexed version, you can also include these two files ‘fotaclient.odex’ and ‘fwupgrade.odex’.

    At the library right now so hopefully I can get a quick reponse so my time doesn't run out.

    I downloaded the nc6 tar file and it tells me md5 mismatch. I'm not real familiar with those but I know they are basically a signing of sorts or a verification type.
    That aside though, so as to speed the process up.....is it possible a faulty download could cause a bad md5? I'm guessing yes, so am downloading now, and hope this is all that's wrong because I can't proceed any further right now.
