Super SU - Update Issues

 My secondary phone right now is a Google Nexus 4 (LG MAKO). I basically want to tinker around with the latest version of Android and I am taking it abroad when I need to be flexible and be able to swap SIMs.On the device I am an avid Super SU user. Unfortunately after flashing Android 4.3 (and re-rooting of course) the Super SU binary update does not succeed (no progress shown for ~ 30mins). I looked around and found a couple of resources rg. that issue:http://forum.xda-developers.com/showthread.php?p=31887507‎http://androidforums.com/evo-4g-lte-all-things-root/701522-help-supersu-not-updating.htmlIn the first link the following easy guide is mentioned:

• first try update binary using Super SU for few times, if still installation failed try to download old superuser through play store.
• Disable superuser for Super SU in settings>Superuser
• In old superuser, go to info and then tap the "tap to check updates" and update the binary.
• Then, enable superuser in Super SU and voilaa!!... try it..
