I have a retail tablet(Crystal Audio, GR) that after many tries I have managed to root it, with Kingo Root. I can the application SuperSu installed and when I am trying to perform root actions, it asks me for granting privileges. Everything godd, up here.

I have followed the steps described here (moved apks to system and try to install them etc) but I cannot install them. After tapping the apks and clicking install, it returns with an error "Installation not done". I have tried to do it with adb, but I am not allowed to remount /system as rw(kernel issue?).

How to proceed? Any ideas appreciated.

  • You can pick the GApps archive from Goo.im and flash them via custom recovery. For more details, please see How can I install the Google Apps Package (Play Store, …) on my Android device?

  • Some questions here as I am not very familiar with the recovery screens. Is is supposed to be named as update.zip? My recovery has the following relevant options. "Apply update from ADB", "Apply update from TFCard", "Apply update from cache". Both the last 2, lead me to an empty dir with the only actual option being the "../" directory(one dir level up). How would you approach it?

  • Does your device have a custom recovery, or are you talking about the "stock recovery" it ships with? I'm not sure whether it's possible with the latter.

  • Stock one...lets say I am installing CWM recovery. Is it pretty easy then to flash the zip, I suppose? The problem is that I dont know how easy is to install a new recovery outside of Play store.

    I'd say so, yes. CWM offers to "install update.zip from SDCard". For details on CWM, you can take a look at its tag-wiki and its most frequented questions.

The solution that seemed to work, at last, was the following. I connected the tablet with USB into my PC. Then downloaded the signed package of gapps for my Android version, from http://Goo.im and moved it in the same dir as the adb executable.

After that, I booted the tablet in recovery mode, chose the option "Update from ADB", and run the command "adb sideload gapps.zip", where gapps.zip is the filename downloaded earlier. Everything run good and I can now see, the necessary services.
