So I'm currently on ICS on my Droid 4. I tried to install the JB gapps through recovery and everything seemed to work fine until I actually booted the phone back up. Now the Play Store won't open and just says "google play has stopped working". I figured, ok, no big deal I'll just install the old version. Now the old version won't install through recovery, the installation keeps failing with the message "cannot verify whole-file signature." I've tried multiple gapps versions, even tried reinstalling the JB version I originally installed and they all give me that message. I can't even seem to update to JB now, I think because there is some conflict with gapps that is stopping it. Anyone have any ideas/suggestions?
