    ---This thread probably won't be up for very long---

    So my phone has the latest updates (1.11.653.0 710RD) on the Boost EVO Design. I want to start installing a ROM now. But I can't determine where to go from here.
    I like 2fast4u88's Kindgdom Ics xFuZiionZz ROM, because it looks like it will run very smooth, and is focused on being flawless. But he also recently gave us Kingdom FastKernel Ics v2. What I wish I could do is flash the xFuZiionZz ROM running off of the FastKernel.
    Here are my questions:
    -Could I run both the xFuZiionZz ROM and the FastKernel together?
    -Should I wait for other kernels?
    -What would I have to do to get ready to flash either of those?
    -Should I use CWM as my recovery tool to flash them?
    -Do I need to root or deodex my phone before any of this?
    Sorry guys, I feel like such a noob. I came from the Samsung Prevail, it was much less complicated to to mod that phone. I'm glad I have the Design, but the Prevail was definitely more simple.

    Kernel will work with my rom, also should any other rom including stock. You need to unlock, install cwm and install rom of choice. Follow the install instructions for the rom as well. You may also want to backup the stock rom before flashing custom, but stock rom isn't needed.

    2fast, you're the freakin man! (Or woman? Sorry just assuming :p)

    I don't know if this is something you'd be interested in working on, but the only thing missing I'd like to see in any kernel for this device is something KoumaJutsu did on his KoumaKernel for the Prevail. He was able to enable SD swap into an additional partitioning on the SD card. As I understand it, this can add a little extra RAM to the device.

    Still though, you rock for what you've done so far. I wish I could do that stuff. I'd like to learn, but don't know where to start.

    p.s. guess you can disregard my message

    Your talking about swap support I assume, where it doesn't make your phone have more ram. If that is what he said to you guys, he was telling you guys wrong. I would never recommend swap for anything to be honest. I hate it in linux to the point it is turned off, on a phone it will cause the same issues.

    Swap if I recall is one way to trick benchmark scores. How ever swap is similar to what it's name applies. It is a virtual memory that uses some form of storage to emulate your physical ram. In the case you are applying it is writing to a ext partition on the sd card. What swap is used for is if ram drops low, it sends the least used pages to the swap partition to free up ram for what ever it is you open. This is where swappiness comes into play, depending on what you set, will determine how much will be swapped out.

    How ever here lies the issues with using swap. Your physical ram will always be faster then your storage device. Where to have no ill side affects a high class card would be needed. Though even then it will still bottle neck due to hardware designs and sd cards just being slow. Once you get a large amount of swap going it will bottle neck the whole phone, from trying to pull the pages off the sdcard and swapping out pages in the ram to free up that needed ram. So basically you create a big bottle neck that will lead to lag and slowness, you may not be able to notice it as bad on android. But linux I can assure you that you will notice.

    The other thing is sd-cards only have so many read and writes. Where you will be adding wear and tear to the sd-card. Basically anytime you open a said app, switch to another if those pages are on the sd-card. It would be reading and writing the whole time. The other thing is this can just kill your battery life as well. In better terms instead of using swap, you are better off to let the built in task killer of android to do it's job. The design has plenty of ram to keep things open long enough you shouldn't even bother with needing swap.

    How ever I can enable it if wanted, but that is my recommendation.

    Wow, thanks for that. I knew it did add additional wear and tear on the SD card, "burning through memory" essentially. I like to stick to class 10 SD, especially when messing with phones. But knowing more of the cons, I think I'll avoid swap altogether on the Design. At least for now.

    SDK Manager gave me trouble last week, but I reinstalled it and my device is now unlocked, leaving me on my way to CWM now. Thanks 2fast!

    By the way, where did you learn to work with kernels?

    Then just flash the kernel in CWM after the ROM, correct?

    Where I learnt to play with kernels was pretty much how I learnt to play with android in general. Which was play with it on my free time, change on thing and see what that affects and so on. How ever the kernel side looking at others gits gave me a better understanding of it all. Similar to the overclock code on my github, you won't find another source with the same code. Ics the cpu table was change around, where I had to look at others gits to figure out what was going on. Then since our pll2 is half of the other phones I had to switch to the right pll2 and multiplier.

    As for the kernel flash it after the rom. Make sure the rom boots first.
