So you've got your device rooted, and you want to install a custom recovery? Great! Don't just follow any guide you stumble across though, as some of the early recovery packages for the "AT&T" model were actually just copies of the custom Sprint recovery, and then you'll have all sorts of fun trying to install ROMs. ("Status 7" errors anyone?
While this may seem difficult, it's really not. Grab a recovery image (these files end in ".img") such as ClockWork Mod (CWM) or Team Win Recovery Project (TWRP) for your device. Most ROM developers say to use CWM, but they both work equally well.
In our case, we need an image for the Samsung Galaxy S3 AT&T. Telus, Rogers, Bell, and SaskTel phones are (almost*) the exact same phone as AT&T, if you have one of these devices, you will be installing the AT&T recovery.
*NOTE: While we're on the topic, let's take a second to talk about what makes the Canadian I747M different from the AT&T I747.
The short version is... The modem. AT&T is using completely different and incompatible modem firmware in their phones when compared with the Canadian models. Rogers, Bell, Telus, and any other Canadian I747M are the same device (Samsung worked some strange voodoo and got all the Canadian carriers to agree on the same hardware!) which means that if Rogers releases a new modem firmware update, a SaskTel user could install it without issue. AT&T modem updates will not work on Canadian models, nor will Canadian updates work on AT&T phones! I've tried it. Trust me. You don't want to deal with the hassle of fixing it.
