I have an At& t note 2 that has been rooted and currently running baseband I317ucubmk6. I am unable to download ota the new kitkat firmware. I believe it is because of the phone being rooted and?or possibly because of bootloader not allowing downgrade of firmware. Not really sure. Can anyone help me unroot this ? return to stock firmware so that i may upgrade or how to to get the kitkat. on my phone? Thanks in advance
