Key Points to Note

• The MacKay custom ROM and instructions provided in this guide are meant for Galaxy S I9000 model only. Do not attempt installing the firmware on any other model, as you might end up bricking the device.

• Ensure the device is factory unlocked and rooted with ClockworkMod (CWM) recovery or TWRP installed on it.

• Back up important data and settings on the phone via one of the custom recovery tools such as CWM or TWRP to prevent data loss during firmware installation.

• Ensure the device has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) during firmware installation.

• Enable USB Debugging mode by navigating to Settings > Developer Options (if phone is running Android 4.0 or later) or go to Settings > Applications > Development (if running Android 2.3 or earlier). If the device is running Android 4.2, then perform the following steps:
  • Go to Settings > About Phone
  • Scroll down to the bottom of the screen and select Build Number
  • Tap Build number seven times to unlock or reveal hidden Developer Options. Now, select the checkbox to enable USB Debugging mode under Settings > Developer Options.

• Perform a Dalvik Cache wipe before continuing from recovery mode.

• Samsung KIES will not recognise your phone after installing this ROM, as it is a custom ROM.

How to Install Android 4.3 MacKay Jelly Bean ROM on Galaxy S I9000

• Download Android 4.3 MacKay Jelly Bean ROM and Google Apps package for Galaxy S I9000 on computer.

• Before flashing the new ROM do the following steps in CWM recovery:
  > wipe data/factory reset
  > wipe cache partition
  > go to "advanced" and perform wipe dalvik cache
  > go to "mounts and storage" and format system

• In CWM recovery, click Install Zip from SD card and select the ROM zip file copied earlier to the phone's SD card ( repeat this step for installing Google Apps as well). After selecting the ROM file, allow the ROM to be installed on the device. This process may take about five minutes to complete.
