Firstly I presume I do not need to root to do this?
Secondly, will flashing the new firmware with Odin wipe my phone and I would need to set it all up again, or will it simply update the firmware without resetting the phone?
Thanks for any help.
I was on Three branded as well, and flashed the unbranded firmware.
1. You don't need to root the phone at all.
2. You won't lose any data, the phone remains the same as it is. Just do a backup of anything you won't be able to recover if something goes wrong.
