Do not use this guide for any device other than the Galaxy S Advance (GT-I9070 model). Flashing this ROM onto any other device will most probably result in a bricked phone.
You must have your Galaxy S Advance rooted, with a recovery utility like ClockworkMod installed. As always, you want to backup your device and charge it to at least 80 percent.
Finally, enable USB Debugging mode by navigating to Settings -> Developer Options.
