When Jelly Bean source was first released, XDA members wasted no time putting it on anything and everything. This was also helped immensely by a guide by XDA Recognized Developer dastin1015 to help users learn to compile Jelly Bean. As Jelly Bean has become more commonplace around here, more device specific guides have been writte. Among the latest is a guide to compile CyanogenMod 10 for the Nexus 7.
The tutorial comes in a Google Document shared by XDA Recognized Developer fattire. To start, users need to be running Linux. Next, they simply follow the instructions and end up with a booting ROM. While we talk quite a bit about compiling source code here at XDA, fattire has compiled (see what I did there?) a list of reasons why compiling ROMs yourself is beneficial.
You never, ever have to wait for a nightly
You can add or remove as-yet uncommitted features with ease.
You learn how Android works under the hood
You learn how to use Linux
You’ll learn how to use git
You may, even accidentally, pick up a little C, Java, C++, and learn about the build system.
You can personalize Android– make your own tweaks, replace kernels, modules, graphics, add or remove projects, overclock, underclock etc. In other words, you have control over every aspect of your device’s functionality. Your build is custom to you.
You can audit the code for potential security issues such as back doors or trojans (as opposed to just trusting a random person who posts a build). Since CM10 source is open, you can examine every commit, and there are many eyes looking at the code. (does not apply to proprietary blobs, but these are pulled from your device, so you have and are using them already)
You can contribute features/fixes back upstream
You can start ports to other as-yet-unsupported devices (start by copying folders from similar devices to devices/manufacturer/model)
You come to really understand that Android phones and tablets are full-fledged general-purpose computers just like laptops and desktops.
AAAAND….you get huge bragging rights
So the question remains: What are you waiting for? Getting the latest CM on one of Android’s most loved tablets is as simple as following a Google Doc guide. To learn more, head to the original thread._________
