Download the ROM from SamMobile Firmwares. (You'll have to create a free account to download a file.) Make sure you put in the right model number, and download the latest TMobile ROM there. It's a zip file, so drag the file in the zip out to where it's easy to find - C:\ or your desktop are probably the easiest to remember. We have a full guide to how to install it at [Samsung] How to flash Stock ROM via ODIN.
