Disclaimer:

Try all the steps given below at your own risk. If your smartphone gets damaged by following this guide then neither I nor the developers of this ROM will be held responsible for that. So I recommend you to follow every instruction correctly.

Compatibility:

Also, note that this ROM is compatible only and only with Samsung Galaxy W having model number GT-I8150. Do not install this on any other device except the one mentioned as it may cause permanent damage to your device.

Requirements:

  • Charge your Galaxy W at least up to 60%.
  • Take a backup of your phone data and settings including contacts, messages, call logs, memos, etc.
  • Backup EFS folder present in your phone’s system directory.
  • Install mobile specific USB drivers on your PC.
  • Root your Samsung Galaxy W before going ahead.

Steps to Install CWM Recovery on Galaxy W:

  • Download the Odin tool on your PC.
  • Also, download CWM recovery in a specific folder on PC.
  • Now switch off your Galaxy W.
  • Then boot it into downloading mode.
  • For doing the same, press & hold volume down + power button + home button simultaneously until you get Downloading message.
  • Using a USB data cable connect your Galaxy W to a PC.
  • On PC, launch the Odin3.07 which you’ve just extracted.
  • As soon as you launch it, the ID: COM section located in the top left corner will turn light blue with a random number. Also, an Added message will appear in the message box window. This will confirm that your Galaxy W has been successfully connected to the PC. But if such a thing doesn’t happen then it’s more likely to be a problem with the mobile drivers. So re-install the mobile-specific drivers on your PC.
  • Tick the Auto Reboot and F.Reset options present on the Odin window. Keep the rest of the options as they are.
  • Now click the PDA button on the Odin window. Then browse to the recovery.tar file which you have downloaded earlier and select it.
