Need help editing Phone.apk (to disable Noise Cancellation) - Galaxy S II Q&A, Help & Troubleshooting

Hi,
First post here, hello! and I'm new to android and smartphones in general, be gentle!
I have a Samsung Galaxy SII and I'm one of the ones who suffer from the "echo problem" during calls. In my case, turning off noise cancellation fixes the problem. The only problem is, as you might know, that you can't disable it permanently (without editing the Phone.apk).
What I'm trying to do is what's stated in this thread: http://forum.xda-developers.com/showthread.php?t=1372718
(I can't post there need 10 posts)
First of all, the software I'm using is as follows;
ROM: CheckROM v4
Kernal: DarkKnight v2.3
Modem: KI4
Am I right in thinking that my ROM is deodexed?
So, what I've done:
1. Install AndroidSDK and ADB. I followed this guide: http://www.youtube.com/watch?v=y6K1XLmafPc&feature=player_embedded
2. I found the Phone.apk in my phone and put it on my PC.
3. I've attempted to decompile Phone.apk using APKTool, using this guide: http://www.miui-au.com/add-ons/apktool/
This is where I'm stuck, I've gotten up to the stage where you put "apktool d Settings.apk" in the command prompt. This is the error I get:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now, I may be wrong but is this because it's a "Themed" apk?
I would appreciate any help! Thanks.

I've already replied on the other forum, but I'll add it here incase anyone else has the same problem.
You need to add the file "twframework-res.apk" to where apktool is aswell. Then after doing "apktool if framework-res.apk" do "apktool if twframework-res.apk" then carry on as normal .

Ah great, that seemed to work thank you!
Now I need to edit it and re-compile it again. Hopefully I can manage that, but it's likely I'll have a problem, will post back if I do.
