This is the app we are going to use to flash the xposed framework to the phone. U can also use it to flash any custom rom/zip you have to your phone.
After making sure the above two are as required,
Download the xposed framework zip for your phone, i would have upload the one for innjoo halo plus, but am on an area with poor network.
Place it in the root (outermost folder) of your external sd.
Launch flashfire and follow this guide to flash your exposed framework to your phone. Guide on how to flash exposed using flashfire
After the phone has rebooted, install the xposed framework alpha apk
and you will be done.
It might take some time before the flashing is done, be patient. In my part it took only three minute.
I will update this thread as time goes by and when i have good network connectivity.
if you want to unistall xposed framework, flash this uinstaller zip.
