ugh i give up.. tried twice already and still no root -_- says no SU binary installed blah blah
Did you flash supersu update.zip when at cwm?
What i did is:
1. Cwm clear data/ factory reset ; clear cache; advanced / clear dalvik cache.
Mine at attachments, use puredeodexed v2, root, lb
this tutorial is for 4.1.B.0.587 only!
1) flash the 4.1.A.0.562 kernel http://www.mediafire.com/?twn09p8ekug46f7 (thanks to sathurnn)
note: you might get errors after the reboot, don't worry, this is normal and step 3 will fix that.
