Have you tried flashing the superuser.zip from the recovery. Worked for me but make sure that you first flash the superuser and then fix permissions before re-booting your phone...
Hope that helps...;)
Best,
Thanks for uploading the ROM! I thought, we would never see it after your last post.
Agree with you on your point. I don't mind donating whatever best I can... Do let me know the way to do so... :)
Best,
