as in title, my device is htc Chacha, i was trying to change my status bar color from white to black,
i used root explorer to copy SystemUI.apk and edit it, i've changed "statusbar_background_opaque.9" and "status_bar_background.png"
with paint to make it full black, when i copied it again to system and restarted the status bar fully disappeared,
not this only, when i copied the orginal SystemUI.apk "non-edited" back to system it didn't appear again, so it's hidden till now
what should i do ??
