[Android Software/Hacking General [Developers Only]] XTCrefugee:
I'm attempting this on my GT-i9505, but I get problems at Step 5.

I'm on Windows 7, latest apktool, and have installed framework-res.apk, twframework-res.apk and SystemUI.apk.

Here's the output:

C:\Users\Public\Documents\Android\apktool>apktool b SystemUI almostdone.apk
