Kindly you have recently updated "aapt", kindly update the file "aapt.exe" for windows, in the framework-miui-res.apk have this kind of errors:

invalid resource directory name: C: \ Apktool JB \ framework-miui-res \ res/drawable-
land-xxhdpi
invalid resource directory name: C: \ Apktool JB \ framework-miui-res \ res/drawable-

Thanks
