These are the instructions to install ClockworkMod Recovery on the Samsung Galaxy S3 smartphone with the model number SHV-E210K using the Odin flash tool and a computer.

REQUIREMENTS

• The CWM Recovery file found in this guide is the CWM version 6.0.3.2 for the GT-I9300, and according to the original poster at XDA, works for the Korean variant too. However, we do not recommend you follow this guide for any other model numbers.
• You can have your Samsung Galaxy S3 SHV-E210K smartphone rooted or unroot when flashing your custom recovery. There is no difference either way you choose.
• You must have a Windows PC to follow this guide and flash a custom recovery on the Korean Samsung Galaxy S3 smartphone. The Odin flash tool does not work for any other device.

BEFORE WE BEGIN

• Download the Samsung USB Drivers from our USB Driver downloads page. You should install those drivers on your computer before you start the guide.
• You must unlock the hidden Developer Options menu by tapping on the Menu > Settings > About Device > Build Number. Keep tapping on the build number at least seven times and it will eventually let you know that the menu is now unlocked.
• Turn on your USB Debugging Mode from the Developer Options menu by tapping on the Menu > Settings > Developer Options > USB Debugging Mode.
