    After time with a good amount of roms, modifying the rooted stock rom steev for the 7042 posted seems to be the most stable for now. With a few changes it works like a charm, all except googe play and the permissions. Some apps aren't compatible because of carrier restrictions, others because the tablet doesn't have the proper permissions. Thiss seems to all comes down to the build.prop and the system permissions so I was wondering the different ways people have tried. For instance, in Steevs rom, google+ is an older slimmed down version with no hangout support, in Vampirefos mobiz edit its the latest version. Even in vampirefos rom there is still some limiting occuring, so maybe with the proper tweaking we can get a some more apps and better versions.

    This is my current build.prop, which is pretty much steevs stock rom build but I added the tweaks at the bottom for wifi and media. No permission changes or anything.

    Tablet / Device:
    Coby Kyros MID9742, Dell Streak 5, Samsung Galaxy S4, Nexus 6
    build.prop:
    The work done on my tablet was more extensive than just the build.prop. While my build.prop is essentially the same as yours (see below) I use a Galaxy Tab 2 fingerprint instead of the Galaxy Tab fingerprint you use. I don't know if using the GT2 instead of the GT makes a difference or not. And yet, while editing the build.prop does help, it isn't the end all be all for Play Store compatibility. steev's ROMs are all based off the stock Coby ROM, and the Coby ROM is missing a quartet of files in its permissions directory. If steev added them already to his ROM, then that's terrific. However I have seen users of steev's ROMs complaining about not being able to download Facebook or Angry Birds. That is because the files in question are all related to GPS and the location service, neither of which are present or active on these tablets, and which both Facebook and Angry Birds require.

    My build.prop:

    # begin build properties

    The XML Files:
    • android.hardware.location.gps.xml
    • android.hardware.location.xml
    • com.android.location.provider.xml
    • tablet_core_hardware.xml
    Once these files are copied to \system\etc\permissions, have their permissions fixed to rw-r--r--, and the tablet rebooted, the apps that were formerly incompatible show as compatible. For example, before I did these changes I attempted to download the Facebook app and failed. Afterward, no complaints from the Play Store regarding Facebook.

    framework-res.apk:
    However, while I could download Facebook, install it, and use it after adding the XML files, I couldn't use Google Earth after downloading it from the Play Store. That's because of one added issue. While the XML files are present, the network location service still isn't active, and thus Google Earth crashes upon start. Users of custom ROMs such as yourself do not have this problem because the network location service in the ROM is activated. It's only the people who stayed with the stock ROM that have that problem. I fixed it on my tablet as well as my roommate's tablet, but for most Kyros users it will never get fixed. To fix it requires decompiling framework-res.apk and, truth be told, they simply don't have the patience and/or possibly the knowledge of how to fix it. Most will simply not bother.

    Summary:
    In order to maximize Play Store compatibility:

    • Use a build.prop with a Samsung fingerprint.
    • Copy the missing XML files over to \system\etc\permissions.
    Stock ROM only:

    • Decompile, edit, recompile, and copy a new framework-res.apk to the tablet.

    Steev has added location functionality, so Facebook , maps and angry birds show up so it has to be the other XML files and a different fingerprint that allows the mobiz rom to grab the other apps and the latest version of Google+. Its odd though cause i can get maps and google earth on steevs, but when i install maps on vampirefos mobiz I get maps & navigator, i actually think its a newer version of maps.There has to be a combination of a good fingerprint, and XML files that would give use full access. The mobiz is the best so far but I'm thinking the few apps that arnt showing up is permission related. I thought the mobiz rom has all the mods u suggest? Could there be a few more permission related files that are missing from the usual all winner fixes out there?

    Thanks for the example build.prop files, ziggyzag and Traveller.
    Wouldn't the Nexus 7 tablet's fingerprint be a better choice for Google Play compatibility?

    @ziggyzag: 9742 build.prop, and one I worked on using the stock build.prop as a base.

    My combination of build.prop, XML files and modded framework has resulted in only one app I know of not showing in the Play Store: Tune-in Radio. That app isn't supported on "unofficial" Android devices, which is something not even my fixes can overcome. The developer set a check in the Play store to prevent installs on "unofficial" Android devices, of which the Kyros is one.

    I've heard Netflix isn't compatible though it appears in the Play Store. I haven't tried to install it myself so I can't verify things.

    I have never searched for Tune-in Radio before so no ideal if it was available on my other roms, any way just did a search on my cm10 and the app was available, and I installed it.

    Can you confirm that the lines which have to be modified in the framework-res are those ?
    Thanks !

    Everything you need to know about making the changes to framework-res.apk yourself can be found here.

    My Dell Streak is running CM7 and can update Tune-in Radio without a problem. Yet I can't do it on the 9742, and I've spent quite a bit of time trying to figure out why. I finally gave up on it and simply sneakernet Tune-in Radio from the Streak to the 9742 whenever there is an upgrade.

    Yet...knowing my luck, I'll try it again since Google Play has been upgraded and it will suddenly work.

    So the best fingerprint for ics would be S3 ? or galaxy tab?Aside from location permissions, are there anymore permissions that are added?

    I'm trying to release the location of coby 7022 Jelly Bean, both in windows and in linux, but it still fails.

    I follow these commands:

    Also copy framework-res.apk from your ROM and framework.diff to the apktool3 folder

    Change to the folder on desktop:
    Code:

    $ cd Desktop/apktool3

    Install the framework:
    Code:

    $ ./apktool.jar if framework-res.apk

    Decompile framework-res:
    Code:

    $ ./apktool.jar d framework-res.apk

    Apply the patch:
    Code:

    $ cd framework-res
    $ patch -p1 < ../framework.diff
    $ cd ../

    Recompile framework-res:
    Code:

    $ ./apktool.jar b framework-res

    Now replace resources.arsc in the original apk:
    Code:

    $ cd framework-res/build/apk
    $ zip ../../../framework-res.apk resources.arsc

    Push the modified framework-res.apk to your device and the NetworkLocation service should work


    location Jelly Bean.rar


    All files are already on the link.

    Can someone fix this?

    Ok, got it to work on 8127.

    Adding permission files and modifying framework-res.apk is not enough to get a fully fonctionnal location service ! The ROM need to contain NetworkLocation.apk in system app.
