there is must be something with signing kitkat apk different than 4.3 and lower firmware.
I used the same method of signing A System apk of taking META-INF and AndroidManifest.xml and inserting them into the new APK.
apktool version 1.5.3
phone:NOTE3 SPRINT N900P 4.4.2 STOCK FIRMWARE.
Hello,I have problem with recompiling any system apk for kitkat firmware,tried to decompile and recompile framework-res as the usual way of any 4.3 firmware and lower,it does decompile and recompile successfully but when I replace it back instead of the original one I got it stuck at sprint screen for NOTE3 SPRINT .also when I try with SecSettings ,the settings icon disappear after replacing the original one,I even tried building the apk without any modification and I got the same thing.
