When I flashed Broken Out on my Spectrum, Polaris office was removed. I have my nandroid backup of the original rom. I see that my Polaris Office apk is located in the system.ext4.tar folder from the backup I did. The apk shows under /system/app. Can I just copy and paste the apk file and install Polaris Office on my Spectrum? I see two files; one is PolarisOffice.apk and the other is PolarisOffice.odex Is this doable without messing up my phone?
