Stock Android SMS app with one additional feature: automatically enable/disable mobile data when sending/receiving MMS messages

Installation

Requirements:

• Android 4.4 KitKat (no clue if it will work on any other release)
• Rooted

Steps:

1. Download Mms.apk from releases

2. Overwrite stock Mms.apk on your device. This can be done using a file manager app with root privileges, or using the command line:

   1. Push Mms.apk to your device

        adb push Mms.apk /sdcard/
      

   2. Connect to your device and become root

        adb shell
        su
      

   3. Get the system drive for your device

        mount | grep system
      

   4. Remount the system partition as read-write using the mount point you got from the previous step. Ex:

        mount -o rw,remount /dev/block/mmcblk0p9 /system
      

   5. Remove the existing Mms.apk

        mkdir /sdcard/mms-backup
        mv /system/app/Mms.apk /sdcard/mms-backup/
        mv /system/app/Mms.odex /sdcard/mms-backup/
        mv /system/priv-app/Mms.apk /sdcard/mms-backup/
        mv /system/priv-app/Mms.odex /sdcard/mms-backup/
      

   6. Copy the new Mms.apk and set permissions

        cp /sdcard/Mms.apk /system/priv-app
        chmod 644 /system/priv-app/Mms.apk
      

   7. Remount the system partition as read-only using the mount point you got earlier. Ex:

        mount -o ro,remount /dev/block/mmcblk0p9 /system
      

3. Reboot
