I flashed the stock ftf in flashtool and restarted entire process. Does it reboot after phone loads up or during boot up? I think the new xposed update disables during safe mode(not sure what you installed) try that first and uninstall the module or xposed itself in safe mode if it fully boots up. go to power menu, long press restart and itll go to safe mode.
After installing installing xposed module if your phone goes into bootloop, boot into recovery, flash Xposed-Disabler-Recovery.zip automatically created by Xposed and located in the internal memory. Then reinstall Xposed and enable modules one by one to find out the bad one
