I recently got an 8330 from Sprint and it came out of the box with the 4.5 OS already on it. I am wanting to downgrade to get the "ROAM ONLY" option back. All the tuturials I find are for people who upgraded using the desktop manager. I do not have any of the options in order to do this. So, what i am asking, is there a way to downgrade when i was not the one who upgraded the software?
THanks,
Brian

Download and install the 4.3 OS software to your PC here (2nd link):

Follow the installation instructions in the Upgrade/Downgrade link in my sig below.

If you need the Desktop Manager software to do the downgrade, download it and install it to your PC. I recommend version 4.6 without Media Manager:
