- The CWM Recovery file found in this guide is the CWM version 184.108.40.206 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.
