The link is a Google drive link.
It contains 4 files: SystemUI.apk, 3MinitBatterySettings.apk, MinitBatteryResources.apk, WETAmod.apk.
The SystemUI.apk file is from: ZSU3DTI1......it is the Stars Wars ROM
Install the APKs
Copy SystemUI.apk to /sdcard on phone
Reboot to TWRP
Mount system as r/w
From Main menu, select Advanced/File Manager
Got to system_root/system/priv-app
Copy SystemUI folder to /sdcard (backup)
Delete arm folder
Copy /sdcard/SystemUI.apk to the current folder
Make sure the permissions are 644 for SystemUI.apk
You may have to re-install 3MinitBatterySettings.apk after reboot
The WETAmod app will allow you to enable network traffic , turn on 3Minit, hide stock battery.
I have only added code in SystemUI for th 3Minit Battery and neteowk traffic.
