F.A.Q.​

0.1 Before replacing/modifying/deleting/uninstalling anything, I strongly advise that you make a backup of the original should anything go wrong. You have been warned!

0.2 This is not a Recovery Zip, it's meant for you to get only what you need. All you need is ROOT.

1. Something is not working / It keeps telling me that I have to update Google Play Services:

This means that you haven't installed PrebuiltGmsCore.apk that's included in this package. It's a newer version of Google Play Services that's required for several of the apps to work. I highly recommend installing it before installing anything else.​

2. Google Search / Google Now keeps crashing:

You must copy the following file from the included /system/lib folder to /system/lib in your device:

libgoogle_recognizer_jni_l.so

.

Make sure that permissions are set to 644.

You'll need a file explorer app with root features. I personally use File Explorer with the Root Addon as it makes it extra easy to move things around since it has a dual panel feature and also allows you to change permissions.

Also, for the launcher to work properly, you need at least the following installed, in this order:

Google Play Services - PrebuiltGmsCore.apk
Google Search - Velvet.apk
Google Home - GoogleHome.apk

3. Ok Google Feature doesn't seem to work:

First, make sure you've done all the above steps to ensure that everything else for the Launcher/Google now is working.

Then, from the homescreen:

Menu > Settings > Voice > Offline Speech Recognition > Update if possible or Uninstall and Re-install the English (US) file.
​

4. Photosphere is not working in the camera app:

You must copy the following files from the included /system/lib folder to /system/lib in your device:

libjni_filtershow_filters.so
libjni_mosaic.so
liblightcycle.so

Make sure that permissions are set to 644 on all those files.

5.Google Hangouts force closes when video calling:

You must copy the following file from the included /system/lib folder to /system/lib in your device:

libvideochat_jni.so

Make sure that permissions are set to 644 on all that file.

​

6. I cannot install Maps.apk:

You'll have to uninstall your current Maps in order to be able to install the new one. I'm not sure why it is that this is the only app that cannot be updated, but that seems to be the case. I suggest backing up the original APK first with an app such as Titanium Backup and then uninstall Maps, also using Titanium Backup. Once uninstalled, proceed to uninstall the new APK and all should be fine. You may have to restart the device after uninstalling the old Maps, though I personally didn't have to.​

7. How do I make the launcher icons smaller?

In order to make them smaller you have to use Xposed Framework + Xposed App Settings to lower the DPI on the launcher.

You can get the latest Xposed Framework HERE. If you don't know what Xposed Framework is, please take a look at this post HERE.

Follow the instructions in the link above to get Xposed Framework installed. Once everything is done, open Xposed Framework go to Downloads and install App Settings.

After done installing, go back to Xposed Framework > Modules, and enable App Settings.

Reboot your Device.

Once Done rebooting, open App Settings and select Google Seach (the blue icon) Thanks to bakercj for clarifying this one.

Turn it on and change the DPI

400 DPI = 6 icons in the dock and App Drawer Grid 5x6

320 DPI = 7 icons in the dock and App Drawer Grid 6x7

Make sure to tell it to save, and then go back to the home screen. If it didn't take effect, reboot your device.
​

8. How do I add more home screens?

Home screens are added automatically when you try to add a widget/shortcut and slide your finger to the right of the screen while holding the new content.
​

9. Google Now does not show up when I swipe left on the launcher:

Press menu in the launcher's homescreen > Go to Settings > Enable Google Now.

Look at the screenshots for more guidance.
​

10. Google Chrome doesn't work properly:

You must copy the following file from the included /system/lib folder to /system/lib in your device:

libchromeview.so

Make sure that permissions are set to 644 on all that file.

You'll need a file explorer app with root features. I personally use File Explorer with the Root Addon as it makes it extra easy to move things around since it has a dual panel feature and also allows you to change permissions.
