Rename old SecTelephonyProvider.apk to SecTelephonyProvider.apk.bak in system/app
Paste new SecTelephonyProvider.apk. and set permissions to 0644 (rwrr)
Rename old SecMms.apk to SecMms.apk.bak in system/priv-app
Paste new SecMms.apk. and set permissions to 0644 (rwrr)
IMPORTANT: Back up your phone before trying this. You won't be able to remove easily if you wanna go back. It changes system and data files. The messaging does work and it's kinda cool but mms doesn't work.
