I found this solution to install Xposed framework working for me with no issues on my Chuwi HI 8 Android 4.4.4 ROM
Xposed Framework
1. Download/Install Terminal Emulator from play store
2. Download/Install Root Explorer from anywhere LOL ?
3. Download/install Xposed Framework, install the framework but don’t reboot
4. With root explorer go to /system/bin/ rename app_process to app_process.xposed-bak, then rename rename app_process.orig to app_process
5. Open Terminal Emulator
type “su” without quote then execute
type “echo 0x98 > /data/data/de.robv.android.xposed.installer/conf/jit_reset_offset” without quote then execute
type “chmod 664 /data/data/de.robv.android.xposed.installer/conf/jit_reset_offset” without quote then execute
6. Reinstall the framework then reboot
