Revert to Stock Rom from Cyanogen Mod!

My Galaxy 5 running on Android Cyonagen Mod for a few days. And it run smoothly. But after a week i got problem with the battery. Mybe my phone is not compitable with Cyanogen Mod rom. So i have revert the rom from Cyanogen to Stock rom. Here is the steps to to flash your phone back to Stock Rom from Cyanogen Mod.

First you need to have the following:-

1. USB Cable (that came with your Galaxy Handset)
2. Odin Downloaderv4.38 and ops file (download here)
3. Stock Firmware (Multipackage) (download here)
4. Windows PC

While downgrading from Cyanogen Mod, you will need a Multipackage of the preferred firmware, because One Package files cannot convert the filesystem from EXT to RFS, which might mess the bootloader! Some have found the One Package working because they restored to the Factory Settings after the Flashing procedure, but to be on the safe side use Multipackage.
Note - Most of the firmwares downloaded from samfirmware.com are One Package.

Before continuing, make sure that you have the device's drivers installed in the Computer. Installing KIES before flashing the phone will do the job.

Now, follow these steps:-

1. Extract the files you have downloaded..password -
    samfirmware.com

2. Open ODIN and unchecked the One Package option also EFS and One Package Fields should be left as such and make sure that the Auto Reboot and Protect OPS option are checked.

3. Add the files that we have extract earlier...see the image below

 

1. Add EUROPA_v1.0.ops to the OPS field.
2. Add I5503DXJG5_BOOTLOADER.tar.md5 to the BOOT field
3. Add I5503DXJG5_amss_phone_CL464028.tar.md5 to PHONE field..
4. Add I5503DXJG5_PDA_CL464028.tar.md5 to PDA field.
   
5. Add I5503OLBJG4_CSC_SEA_CL.tar.md5 to CSC field.

Note: Unchecked the One Package option also EFS and One Package Fields should be left as such and make sure that the Auto Reboot and Protect OPS option are checked.

4. Shut down your phone.

5. Press and hold the Power Button, Volume Down and the Central Home Button at the same time until you get a screen with Downloading... on it.

6. Connect your Phone to your Computer via USB. Now, one of the rectangular boxes below COM Port Mapping will turn yellow. If not, then reinstall the Phone's drivers and try again.

7. Now, click Checksum Fail or Start (depending on what shows on your Computer)

8. Wait for some time, until the box above the rectangular section which turned Yellow becomes Blue and shows PASS.

Now, your phone is back to stock firmware!!
