Great! What Android versions can be ran on this phone?
JellyBean - 4.2.2 - TouchWiz ROMs are 4.2.2 and there's a few CM10.1 ROMs out there still. JellyBean - 4.3- CM10.2 ROMs are rolling out but remember, you may encounter bugs as it is still a WIP (Pretty stable, though.)
Cool, but I'm a noob, what should I start off with?
My suggestion to you is for you to run some TouchWiz ROMs to get you comfortable with the flashing, nandroiding, tweaking processes and then move on to something else. Above all read and search.
Okay, I see.. but I don't quite understand what flashing, nandroiding, tweaking, etc. mean?

Okay, I think I'm ready to begin! Where do I start?
You have a few ways to go here..
But before we continue, let me explain something to you. Our phones have this 'flash counter' built in. There is a way to reset it after you've triggered it, so don't be alarmed.
Flash counter? What's that?
The flash counter is a binary counter built in Samsung phones that is used by Samsung to basically help identify if you have been tampering with your firmware and flashing unofficial software.
Each time you flash unofficial firmware via Odin, your binary flash counter goes up by 1.
Ah, okay.. is there anyway to bypass that?
Yes and no.
How to get root easier and faster, triggering the counter:
Chainfire has developed an way to flash a custom recovery and root your phone.
You can backup your apps using Titanium Backup found in the Google Play store.
Use apps that require root.
What can I do now that I have a custom recovery?
Make a NANDROID backup of your current setup and restore that backup!
Flash ROMs, modems, kernels, themes, etc.
Wipe data, clear cache, etc.
Credits and Thank you's:
- s15274n for his great guides and borrowed words!
- Woodrube for his great guides and borrowed words!
- Anyone else I may have missed.
Note: I will update this thread daily and keep everything current.
These are my ways of flashing my device and they have worked perfectly, there are other ways as well and they have been posted.
So look around if you find this confusing!
Q: I flashed back to stock, but my phone hangs at the Samsung logo, what do I do?
A: Don't forget after you ODIN, you have to boot into stock recovery, wipe data and cache, reboot!
Q: How do I get into Recovery Mode?
1. Unplug the USB cable.
2. Shut down the phone.
3. Hold down the 'HOME' + 'VOLUME UP' buttons and press the 'POWER' button for about 5 seconds to enter Recovery Mode.
Q: How do I get into Download Mode?
1. Unplug the USB cable.
2. Shut down the phone.
3. Hold down the 'HOME' + 'VOLUME DOWN' buttons and press the 'POWER' button for about 2 seconds until a WARNING! Screen appears. Press the 'VOLUME UP' button to enter Download Mode.
