Sorry everyone for keeping you waiting. Been busy lately.
But to answer the question about .893 or busybox, no on both.. I did not do the .893 flash yet. I am still stock except for root and removing all the crap. And I did not apply the busybox lines. Just the one for Root Exploder (Explorer) from the OP.
Just thought I would mention that I restored a nandroid backup I did when I was straight stock before I deodexed. Then applied the premi-root.
I didn't do the 893 flash yet because I'm seeing how things go with it first. Because My laptop decided to go bouncing down the stairs. So I have no way of doing an FXZ right now and need to be extremely careful. Unless someone knows how to or has done a self contained FXZ that could be done from the phone itself from the fastboot menu etc?
Again, sorry to keep you guys waiting.
