euser1: I was wondering if you would share which operating system you changed those apk's on? So far I have been very unsuccessful on the windows version. I am able to decode and rebuild with changes and sign the apk file, but when I attempt to install on the edge it fails. I have even tested with only decoding, rebuilding, and signing without any changes and still it fails.
As of this post I am installing a wubi Ubuntu to try the linux version as the apktool author's videos were created on that system.

If you are also using Windows version have you noticed and nuances or quirks to make this work?
