  2. Next, download the Gapps for Jelly Bean file from here. Don’t extract it. Note that you should download only the file for Android 4.1 Jelly Bean and not the other ones for the previous Android releases.
  3. After the download is complete you should connect your Captivate device to your PC. Transfer both files on the internal sd card. Disconnect the phone from PC.
  4. Power off the phone. Boot into CWM Recovery by pressing simultaneously ‘volume up’ + ‘volume down’ + ‘power’ buttons. Release the buttons when the screen powers ON.
  5. Select ‘backup and restore’ option if you wish to create a full backup of your currently installed ROM. After the backup is finished, proceed to the next step or, in case you don’t want to create any backups then skip this step.
