Google Play Store won't download apps after reinstalling I had mistakenly uninstalled the stock Play Store on my rooted Lava Iris X1 Mini running Android 4.4. I reinstalled it as a system app after downloading the apk from an external site. Now, I cannot download any apps from the store, because as soon as the download starts, play store crashes. It doesn't even work when it's installed as a user app. Clearing data and cache of Google Play Services also doesn't fix the problem. Any way to prevent this problem? Thanks in advance.
You can try downloading the play store from GApps. You will probably want the pico version... You then have to flash it with a custom recovery (e.g. TWRP).

Good Luck ;)
