In the customized Android system, all pre-installed google apps are missing and it's not allowed to add google account. I downloaded the Gapps from http://goo.im/gapps, but I cannot install the apps due to signature issue
Is there other possible way to retrieve the "add google account" option back?
I wasn't aware that I need to push the Gapps into /system/app to avoid signature problem. When I did, it works!
