Step-3: Boot the phone into CWM/ TWRP recovery mode by pressing and holding Volume Up, Home and Power buttons together

Step-4: Create a Nandroid backup of the current ROM which can be restored later if the new ROM does not work or users wish to go back to the previous ROM.

CWM: Select backup and restore, name the file and confirm the process. Go back to main recovery menu when the backup is completed

TWRP: Press Backup, name the file then Swipe to confirm the process

Step-5: Perform a Factory Reset. This will wipe all data from system partition, which means the device will lose installed apps data and all the other system files [Factory Reset does not delete contents from internal or external storage.]

CWM: Select wipe data/factory reset and confirm the process

TWRP: Press Wipe and swipe to confirm

After the Factory Reset is applied, find Format/ system option and apply it

Step-8: After the installation process is completed, return to the custom recovery screen and reboot the phone into normal mode.

Enter the Google Account info in order to take control over the smartphone.

Once the AOSB Android 4.4.2 ROM is flashed on the Galaxy S3 and it boots into normal mode, you should power off the device completely. Boot it on after a minute.
