Ways to install

1. Using the flashable zip (Simplest)

Go to releases and download the installer zip. Then simply flash using any custom recovery such as TWRP

Note:

If your Recovery cannot decrypt data, then you need to have root access. Set props manually using

setprop persist.dbg.allow_ims_off 1
setprop persist.dbg.volte_avail_ovr 1
setprop persist.dbg.vt_avail_ovr 1
setprop persist.dbg.wfc_avail_ovr 1
setprop persist.sys.phh.ims.caf true

AFTER booting into system

2. Using the Installer Script

Note: If you're not rooted or are using magisk (that's systemless so it doesn't work), boot into TWRP, and mount system as r/w

Run bash ./install.sh (uses adb, script needs to be run on a computer)

3. Manually

Push the ims folder found inside the 32bit / 64bit folder

Note: If you're using a version older than AOSP v216, you'll also have to push the android.hardware.telephony.ims.xml to /system/etc/permissions. The script and the zip will automatically add it for you

Set the following properties using setprop

• persist.dbg.allow_ims_off to 1
• persist.dbg.volte_avail_ovr to 1
• persist.dbg.vt_avail_ovr to 1
• persist.dbg.wfc_avail_ovr to 1
• persist.sys.phh.ims.caf to true

For a 64 bit device (arm64)

Copy the 64bit/ims (don't copy the 64bit folder, only the ims folder inside it) folder to /system/priv-app

For a 32 bit device (arm & a64)

Copy the 32bit/ims (don't copy the 32bit folder, only the ims folder inside it) folder to /system/priv-app

Ways to uninstall

1. Using the flashable zip (Simplest)

Go to releases and download the uninstaller zip. Then simply flash using any custom recovery such as TWRP

2. Using the Uninstaller Script

Note: If you're not rooted or are using magisk (that's systemless so it doesn't work), boot into TWRP, and mount system as r/w

Run bash ./uninstall.sh

3. Manually

Set the following properties using setprop

• persist.dbg.allow_ims_off to 0
• persist.dbg.volte_avail_ovr to 0
• persist.dbg.vt_avail_ovr to 0
• persist.dbg.wfc_avail_ovr to 0
• persist.sys.phh.ims.caf to false

Remove the ims folder from /system/priv-app/
