Post 2: Stock Roms

Post 3: AOSP Roms

*** If you're going from a stock rom to an AOSP rom, read this ***

When you flash an AOSP rom it creates a folder marked 0 on your sdcard, and once it's created, you will ONLY be able to access files in the 0 folder, whether in the rom itself or in recovery. Here's a workaround.

1) Flash back to a stock based rom (If you haven't flashed an AOSP ROM yet you're already here)

2) Using a file explorer (and making sure "show hidden files" is checked) create a folder called 0 in the root of your sdcard if there isn't one there already. Cut and paste everything else in the root of your sdcard into that folder (the one called 0). You can copy and paste if you want but it'll be slower and you'll double the amount of space you're using.

3) Go ahead and reboot into recovery. Do a backup of your current setup and then install your new ROM

4) Everything should be where you expect it to be. If you choose to go back to a stock rom, you'll just have to flash the rom, cut everything out of the 0 folder and into the root of your sdcard, and then make sure you delete the 0 folder once it's empty so that TWRP can see everything it needs to.

Explanation:

I thought it'd be nice to have a central place to see what's what when it comes to sprint Optimus G roms. At first I did this to sort of keep my thoughts straight on the various available roms, but then I thought hey why not share with the community. Also we're coming up on finals week and I have a very special type of procrastination in which I clean, organize, make threads, or otherwise do anything remotely productive that is NOT related to studying. Also also, my intention is to update this post on a semi regular basis, as the development scene is a constantly changing (improving, I should say) place for this phone. That is, assuming people find this thread useful.

About me:

College student who loves his Optimus G. I typically check XDA way more than is healthy, and bounce back and forth between most of the wonderful roms available for this phone.

Thread Etiquette: (please read)

Apparently you're a classy bunch, so I don't think this section is necessary.

Now for the meat of the post! I will not be reviewing ICS roms. Mainly because you have two choices, imperium and lifeless, and their respective jelly bean forms are reviewed here. Plus you should probably upgrade to jelly bean, it's better in most ways. If you need to root, unlock, etc, look here: http://xdaforums.com/showthread.php?t=2050582

Remember, IRC is your friend. If you run into troubles and need immediate aid, go to http://webchat.freenode.net/ and join the channel #lg-optimus-g . They're very friendly over there. Also, there are guides to help you out all over the place on the forums.

Recoveries

Somebody wanted me to say a few words about recoveries, so here goes. We have two options, TWRP (Team Win Recovery Project) and CWM (Clockwork Mod). TWRP is touch enabled, while CWM requires use of volume keys and power button to navigate. Additionally, we're officially supported by TWRP. I'm not so sure about CWM (I don't even know if they do official support,etc).

Honestly, I don't see any reason to not use TWRP. Most users opt for TWRP for its touch friendliness, and ease of use. It also has a nicer UI in my opinion. I used CWM way back on my Optimus S, and it got schtuff done, but I think most of the roms and everything here are tested by flashing through TWRP. So unless you have some special reason for wanting CWM, I'd choose TWRP if I were you.

Thanks to all the devs/testers/users who made these roms possible!
