My suggestion, before you flash xposed framework, you need to backup on twrp (boot+system+nvram+data), make sure you also got uninstaller xposed (once you got bootloop, just flash it.)
After that you can flash xposed framework, wait untill finish & wipe cache+dalvik then reboot system. Wait the process, make sure you have enough battery.
After on main menu, then install apk exposed installer, and bind your module. Done.dwyor
