[Updated] What you need to know about Tizen 2.4 OS upgrade for Samsung Z1

Update: Some items in the Important points sections have been updated.
 
Tizen 2.4 Operating System (OS) for the Samsung Z1 has been in beta testing since the end of September 2015. Since then there has been a huge user demand for the Operating system to mature and flourish into a final release.
We reported a few days that the Tizen 2.4 final release for the Z1 will be on or after 22 26 January in India. There is now confirmation, from Insider sources, that Samsung is looking to also release the update to Z1 users in Bangladesh, Nepal, and Sri Lanka about one week later than India.
 

Important Points

• India release is scheduled for 22 26 January or possibly later, available to all Tizen 2.3 users
• If you are a Tizen 2.4 Beta tester with version COI5 you will have to revert back to the latest official Tizen 2.3 version using KIES. We DO NOT recommend using ODIN.
• If you have Tizen 2.4 version COL5 or COL6 you will receive a Over the Air (OTA) update that will take you to the final version
• Other markets such as Bangladesh, Nepal, and Sri Lanka will get the update about one week later than India
