3. 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. 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.

5. Pre-Requisites:
 Lack of battery power may interrupt the process. So make sure you’ve charged your Galaxy W at least up
to 60%.
 As everything gets wiped in the last step of this procedure, it is necessary to backup all your phone data
and settings including contacts, messages, calllogs, memos etc.
 Backup EFS folder present in your phones system directory. This folder contains all your phones specific
information such as the IMEI, wireless devices MAC addresses, product code, and much more. So a
backup of this folder is essential. There is always a risk that this EFS folder might get corrupted. If so
happened, your device will be completely useless & will no longer be recognized by your carrier. Refer
our article to backup and restore EFS/IMEI data:
1. How to backup and restore EFS/IMEI on Android Phones.
 Ensure that you have installed mobile specific drivers on your PC. This is recommended so as to recognize
your Galaxy W when connected via USB data cable. You can install them by installing Samsung Kies or
manually install them from the link given below:
1. Download Windows 32 bit x86 drivers.
1. Download Windows 64 bit x64 drivers.
 Your Galaxy W must be rooted.
 A custom recovery like Clockworkmod (CWM) or TWRP must be installed before proceeding further.

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 thing doesn’t
happen then it’s more likely to be problem with the mobile drivers. So re-install the mobile specific
drivers on your PC.
Step 6: Tick the Auto Reboot and F.Reset options present on the Odin window. Keep rest of the
options as they are.

7. Step 7: Now click PDA button on the Odin window. Then browse to the recovery.tar file which you
