I've managed to bake Xposed into the system, and it survives reboots!
AT&T XT1058 (Tested)
VZW XT1060 (Tested)
Stock system rooted with Crash's method
ATT_XT1058_(Crash root)_xposed_install.rar for AT&T XT1058 version
I've had "could not open port %r %r %..." error once, and rebooting my pc helped. It seems python can leave port open sometimes, and by that block it for further use. Reboot your pc, and continue from that step on. Should help
Have you installed xposed apk after this flashing process?
Worked like a charm! Thanks CrashXXL!
After installing Xposed do soft reboot, it will activate, but won't live past full reboot, but still, it's something!
There you go, found it:
But I have another problem now: It says "Not a valid aboot" and aborts :(
