[GUIDE] Edgehood's All Inclusive ROM Building Guide

Downloading and moving the Base

This is how I create my ROMs. Other developers along with myself have found that Dsixda's android kitchen can create issues with your ROM, so building from an already existing base is always the safest in my opinion.

First, we will need to get a base. There are many different versions out there, however, they almost are all the exact same. I use beanstown106's base for my ROMs. You can find his base, along with the stock Modem, RPM, and kernel with custom boot animation support here.

Download Bean's base, and extract the files within the ZIP archive somewhere on your computer. I recommend creating a development directory somewhere on your computer.

• I work on Mac OS X, so my development directory is in my home folder under /dev.
• In Windows, this sample directory would be in C:\\Users\YourName\Dev
• Linux is similar to OS X. I recommend placing your Development directory in ~/Dev (~/ is your home folder's directory)

Of course, you can place these files wherever you want :) this is just how I have my computer set up.

Downloading and Installing the Kitchen

This will teach you how to create a base of your own using Samsung's ODIN file and Dsixda's Kitchen.

First of all, you must download Dsixda's Kitchen. Luckily, the Verizon S3 is supported by the kitchen, so BUILDING your base using the kitchen is practically painless. Getting the kitchen running is difficult at times, and you may run into issues later. If you want to evade these issues, I suggest building your ROM from an already existing base. If you don't want to do that, keep reading :P. The kitchen can be downloaded from here. Just click on the latest version, and press the button with the cloud and the word "ZIP" to download the repo as a zip file. Keep that somewhere on your computer...

Setting up the kitchen is a different story. It's relatively easy on Mac and Linux, but because the kitchen is designed to run in UNIX environments, it's a little bit tougher on Windows. You can find a guide for setting up the kitchen here.

Adding The Odin Files for the Kitchen To Compile

The next step to compiling a base using the kitchen is to take Samsung's files, and add them to the kitchen folder. This is pretty simple. Download the VRBLK3 Stock ODIN from here (thanks open1your1eyes0).

Extract the files to the original_update folder in your kitchen folder.

Building Using the Kitchen
Finally, we're ready to build your base using the kitchen. Start the kitchen by navigating to your kitchen folder in terminal (or command prompt through Cygwin on Windows), and typing "./menu" on mac and linux, or just typing "menu" on Windows.

Option 1 within the kitchen should compile a base ROM for you. You can then root, deodex, zipalign, and change the name of your ROM, and much more, from within the kitchen.

When you're done, option 99 will compile your ROM and move a ZIP file to your OUTPUT_ZIP folder within your kitchen folder.

• Renaming your ROM is very simple. After building your base, unzip the files and navigate to /system/build.prop. In the build prop, find the line that says "ro.build.display.id=". Replace the rest of the text on this line with your desired name. Save your build.prop. Thats it :)

Debloating your ROM is fairly simple as well. The list of removable Apps on the S3 can be found here (thanks to whoever made this, you are a god lol). This is a list for the international version of the S3, but most of the files are the same and MOST Verizon Apps can be removed as well.

Just delete the apks that you want to remove from your /system/app folder within your ROM files.

Init.d tweaks are scripts that allow your ROM to execute certain actions upon boot. For example, in my Delta ROM, I have an init.d tweak that zipaligns all apks upon boot.

While this guide won't cover creating your own init.d tweaks, adding them is simple. Take the init.d script that you find somewhere online, and simply drop it into your /system/etc/init.d folder. That's all.

Be aware that a lot of people make claims for their tweaks like "best RAM management tweaks" whn posing the tweaks in another device forum. For example, if you found a thread with the "best RAM management tweaks" in the Galaxy S forums, those tweaks are probably not good for our device since we have more available RAM than they do. Overall, it's best to DO YOUR RESEARCH and design your own scripts.

Build.prop tweaks are lines added to your build.prop file within /system. They can do many things, and many of them improve performance and battery life on your ROM. A simple list of build.prop tweaks can be found here. Just add the lines that you want to add to the BOTTOM of your build.prop file, and save it.

When I first started building ROMs, one of the things that I couldn't figure out was how to add a custom kernel to my ROM. It's actually very simple. Find the kernel you want, download it, extract the zip file, and copy it's files into your ROM in the right locations. For example, you would replace the boot.img in your ROM with the boot.img from your custom kernel, and you would replace the modules in your /system/lib/modules folder with the module files from the kernel. Continue doing this until all of the kernels files are in your ROM.

This is pretty simple. Simply compress your ROM files (boot.img, system folder, Meta-inf folder, and anything else) into a regular ZIP file, move the ZIP to your phone, boot into recovery, wipe data, cache, and dalvik cache, and flash your ROM.
