  • Download AOKP Milestone 1 ROM from the link given below :
  1. AOKP Milestone 1
  • Download Google Apps (Gmail, Maps, GTalk, Play Store etc.) which need to be flashed manually since they are not present in the ROM by default.
  1. Google Apps for Jelly Bean
  • After downloading ROM package & Google Apps, connect your phone to the PC. Enable mass storage mode to access SD card data & transfer both the files on it.
  • Disconnect the phone from computer. Now boot into Clockworkmod recovery. To do so, switch off the phone completely. Press & hold Volume Up + Home Button + Power Key together until recovery mode appears (you can release power button after Samsung logo appears but keep holding other two until recovery mode shows up).
  • After getting into CWM recovery, first & very essential step you need to do is take a nandroid backup of your current ROM so that it can be restored back (in case if anything goes wrong). To back up your current ROM, select Backupand Restore option from the recovery menu & on next screen, select backup. Now It will make a nandroid backup of whole system (excluding SD card). Wait for the backup process to get finished.
  • Select wipe data/factory reset & wipe cache partition to wipe all the data & caches respectively from the phone memory.
  • Now Select “install zip from sdcard” & then “choose zip from sdcard“. Select the ROM file from the location where you’ve transferred it earlier & press on Yes to flash the ROM.
  • Wait for the ROM to get installed. After ROM gets successfully installed, your phone will land in the recovery mode.
  • Again select “install zip from sdcard” followed by “choose zip from sdcard” & this time navigate Google apps package file (gapps-jb-20121011-signed.zip). Press on Yes to install Google Apps.
  • After flashing both the files, Select reboot system now to Restart the phone.
