I've managed to make the S4 statusbar theme by modding some systemui.apk resources.
I dont know how to make a flasheable ZIP, so i will upload the apk, just replace it on ROOT/SYSTEM/APP (Or ROOT/PRELOAD/SYMLINK) and set file permissions (If required), then reboot! Systemui.apk is attached!
How to make it transparent:
First, install Xposed Framework from here.
Install the apk and then tap on "Install/Update", grant root access:
Now, download Tweakbox from here and install.
Go to Xposed Installer, tap on "Modules" and enable Tweakbox. Reboot again.
When it finish boot, tap on Tweakbox app, tap on Statusbar:
Set background color to fully alpha, and clock color to white, go back and reboot!
Note, if you get a black statusbar after reboot, just pull down the notification bar and whoala! it cames transparent.
Time for some screenshots!
Fits with every wallpaper:
It's black when you enter an app, no more ugly white under white icons.
-S4 White Icons
-Transparent statusbar on Touchwiz, black statusbar on apps
-Prevent screen burn-in: As we know, the Super Amoled screen is like very early LCD TVs (Or plasmas), when an image is persistent for a lot of time on the screen, it will burn in (Temporary or Permanently), showing a shadow of the image. Samsung changed the black statusbar from ICS to gray in Jelly Bean, to reduce this phenom, but it still there. With the transparent statusbar, it shows the wallpaper instead of a black, persistent statusbar, so this phenom will disapear!
-H+ icon changed to 4G: Some countries recognizes the HSPA+ connection as 4G (NOT LTE), so, ive changed this icon. (I will add later other Systemui without 4G icon)
I know Tweakbox did almost all the job, all credits go to Xposed Framework and TweakBox developers. I've just edited the SystemUI to get the S4 icons...
Tweakbox: Statusbar shows behind the Touchwiz wallpaper when the device its locked. I dont know how to fix it, because its a bug from Tweakbox app, ask to the developer if he can fix it. Temporary fix: Get a third party lockscreen like WidgetLocker
Sorry my bad english!
