[Samsung Epic 4G Touch] xdapowerapps:
I PM'ed tdunham but realized it is better to post here. I am running JB 4.2.2 on a Tmobile Galaxy S4. Here is what I've done thus far:

1) Pulled /system/framework/framework-res.apk

2) Installed framework.

I: Framework installed to: C:\Users\Syed\apktool\framework\1.apk

3) Decompiled framework-res.apk

I: Loading resource table...
I: Loaded.
I: Decoding AndroidManifest.xml with resources...
I: Regular manifest package...
I: Decoding file-resources...
I: Decoding values */* XMLs...
I: Done.
I: Copying assets and libs...

4) Added the two drawables in /res/drawable-hdpi

5) Added the two strings in /res/values/strings.xml

<string name="download">Bootloader</string>
<string name="recovery">Recovery</string>

6) Tried to compile but received the following errors:

W: Could not find sources
I: Checking whether resources has changed...
I: Building resources...

I am not sure where I am messing up? Any help would be greatly appreciated.

EDIT: I went through each XML file that had this error and added the "+" symbol in front of each value and it compiled. Sorry for this post!!
