Google Calendar install error: Incompatible with other application(s) using the same shared user ID I'm stacked with the following problem with my first Android device (Ruggear RG960 Apex, Android 4.1.2, rooted using Kingo Android ROOT) I bought about a week ago. The problem is when I'm trying to install Google Calendar from Play Market, I get the following error:

Error: Incompatible with other application(s) using the same shared user ID


The same is true for Google Play services, which are required for the most of Gapps.

I tried the following:


http://chinaphonearena.com/forum/Thread-Google-Play-Services-Error-Incompatible-with-other?pid=8598#pid8598 - and even deleted packages.xml completely, wiped dalvik, cache from recovery, etc. - still the same.
https://android.stackexchange.com/a/50520/47233 - I downloaded gapps-jb-20121011-signed.zip and did all the steps, but got this error while trying to install from zip via recovery: Invalid OTA package. Missing scatter. Installation aborted.


At the same time Google says this problem is a common one, but still I cant find the solution for about a week so far. Perhaps this is because I have quite rare device, which is not so widely described. So, any guidance to the right direction will be highly appreciated.

In case anyone needs some more details about the device / performed actions - will gladly provide them as requested.
4 months later support finally shared me the latest ROM that solved all the above issues.
