I'm a newbie about Korean phones, and my model is SHV-E250K (Olleh). It is rooted, and still in the stock room. I didn't install any.
Here are my questions and also my possible actions. Kindly correct me if I'm wrong.
1. My phone is rooted by Odin and there's a SUPERSU app. The device status is CUSTOM. If I click the FULL UNROOT, will it unroot my phone and turn into OFFICIAL status? I want to receive OTA updates badly.
2. If my phone's status is CUSTOM, can I update the software via Kies to upgrade and remove the root?
3. IF the above steps won't work, I am planning to download Odin, the stock firmware of Android 4.4.2 and install it using ODIN... will it work? Did I miss any steps?
Thank you brothers and sisters for your time. ^^
