[Sprint LG G2] br0adband:
While the info is out there, even with searching it can be tough to find the specific info one needs to get this stuff done - it's one of the biggest complaints I've always had about forums online (that's not a jab at XDA directly, it's just how it is everywhere).

Having said that the process is fairly simple if you want to use your Sprint G2 with T-Mobile which is what I do. I've had mine about 2 weeks now and the first time I went through the whole process of just trying to get it working properly on the stock Sprint ROM (ZVD build, hadn't updated to ZVE when I first got the G2) I finally got pissed at how convoluted the process is to just do the SIM unlock for GSM operation. That was about the time I found a post that made it quite clear as the "easiest" way to use the Sprint G2 with T-Mobile and that's just flash CloudyG3 and pop in a SIM card and you're pretty much good to go because Cloudfyfa (creator of the ROM) had done all the footwork for us.

So, that's what I eventually did and it's been working since that first time. The process, as stated, is a simple one (at least how I do it). Here's what you need:

- you need the G2 running a stock Sprint ROM, either ZVC, ZVD, or even ZVE at this point. I doubt yours will be running anything older (like ZV8) so whatever, just get a current stock Sprint ROM on it and you're ready to roll - use the .tot method or whatever, it's up to you

- once you're pure stock, you need to root it and the tool I prefer to use for that purpose is ioroot. A lot of people favor towelroot which works just the same overall and can be done just installing the towelroot apk which you can grab from the website it's hosted at (you can find that yourself)

- after you're rooted, you can either go to the Play Market and download AutoRec by Cloudyfa or find it here in the dedicated thread at XDA - install the APK, run it, accept the risk by clicking OK, then let it install recovery (hence the name, AutoRec(overy). It does everything for you, basically

- once recovery is installed, my suggestion is to boot into recovery at least one time to verify it's installed and working - after that, boot back into the stock ROM, attach the G2 to a computer and copy over the CloudyG3 ROM archive to the G2's internal storage (I put mine in the Download folder, sometimes stuff doesn't appear or work correctly if it's in the root directory but that's my personal way of doing things), either v2.0 or v2.1, it's your choice. I'm still using v2.0 because it just works and I have zero issues with it so far, no sense breaking something for no good reason, but that's just me

- once the ROM archive is copied to the internal storage, reboot into recovery, MAKE A BACKUP OF THE STOCK ROM AT THIS POINT - DO NOT INSTALL CLOUDYG3 TILL YOU'VE DONE A FULL BACKUP OF THE STOCK ROM - seriously, take heed of this advice or else you might find yourself stuck in a situation where you'll have to go all the way back to stock again with a clean flash, then root, then install recovery, etc. It's easier just to do the stock ROM backup right then and there at that point before proceeding

- now, after all that is done and the backup is complete, go back to "home" in recovery and then tap Wipe, slide the slider where it says "Swipe to Factory Reset) and wait the few seconds it takes to do that, when done hit the Home icon again, then tap Install, find the CloudyG3 zip archive, select it, get it started

- after a few moments the Aroma installer will come up, choose to continue, scroll down just a bit to select the LS980 (please make sure you get the right one as you could trash the G2 if you don't) then step through the app choices you want or don't want. If you install v2.1 it will ask you if you want the ROM odexed or deodexed, that's your choice there and it gives you a little tip on what each type does best, so make the choice and then finish the install

- when it's complete reboot and you should be good to go

After all that you can choose to install a custom kernel and I'll go ahead and say right now that installing Dorimanx's kernel for the LS980. I currently use the (now) older 8.7 version with great success, but it's up to 8.9 as of today so, experiment if you want, it's your call.

That should get you going, good luck.
