[LG G Flex] mattwheat:
You can give a man a fish and he'll eat for a day. Teach a man to "GOOGLE" and he can use one of the most important inventions to come from the 20th century to research "how to" anything he so desires. Also in the "Nexus 7(2013) & Moto G" forums there are a couple "how to compile cm and AOSP from source" as well as I think any / all Reserection ROM forums also have a link to a guide to port Reservation ROMs to any device.

And one of the reasons why (and probably the biggest reason why) there isn't a lot of development for this phone is the locked boot loader. Seeing in advance that it was locked and not unlockable probably deterred a lot of devs from jumping on this phone from the got go. If it wasn't for Playfulgod's help in the early stages of the custom recovery we would be even further behind. But you can thank Kintwofan for dropping the cash and donating an lg g flex with a bad ESN to Playfulgod so we could get the ball rolling.

I'm not a dev by no means. I'm a themer and knew enough to get by by before this phone. But thanks to Playfulgod, Dfuse, and kintwofan I've learned enough to be dangerous but also learned enough that there hasn't been a brick bad enough I couldn't come back from or help others come back from. And trust me I bricked my flex more times than most the people reading the xda g flex forums combined. And that's before we had a custom recovery.

I've posted an excellent deodexed zip aligned rooted stock base ROM for those who wanted a deodexed build so that the xposed module theme apks would actually theme everything. But with very little knowledge of building from source or porting, I could only help get the cm11 ROM to the point we have a stable boot and data. But no sound. No body has been asking for a deodexed KitKat base so I haven't done one. But if anyone wants one like my jellybean one then feel free to follow my guide I posted on "how to deodex a ROM". Or im sure I'll eventually get around to deodexing one sometime. But last I remember XDA was started nor maintained to be a place where people could go to follow 2 or 3 lines of instructions that tell you to download then extract " this one-click" root, unlock, flash ROM toolkit.

Its here to share ideas innovations and for those who have the knowledge to teach those who have the desire to learn and participate in the further development of the open source projects.

And I'm not knocking you (original poster) you actually asked how to get started learning. I'm just going on a rant due to the amount or lack of participation to learn development by the majority of the people that post complaints about the lack of development for the flex. If you're on T-Mobile with your payments then you don't have to wait long and you'll be eligible for a jump upgrade.

Its my hopes that the g flex 2 will not be locked down like the flex is due to the g3 is unlockable. Seems like they decide to lock this one down and maybe attributed the lack of sales due to the locked boot loader. But decided against it with the next phone lg released. Which is the lg g3. So maybe they won't lock down the boot loader in hopes to entice more to buy the phone and for more developers to jump on the flex 2's bandwagon.
