I just read this http://forum.xda-developers.com/show....php?t=2692825 a little bit more. Can you guys tell me if I'm comprehending all these right. So step 2 gets me to MK2 bootloader from NB1 that I currently have. And with the MK2 bootloader I'm able to use the 4.3 root methods indicated in the thread. What's preventing 4.4.2 from being rooted isnt kitkat itself but the NB1 bootloader that came with it through ota, because from the look of it after MK2 "downgrade" I'll still have kitkat?
Step 5, if my final goal isn't just to have stock rooted can I flash a rom of my choice here instead of the stock rom indicated in the thread ? If I am able to just flash another rom in step 5, will I still need the stock kernel in step 6 ? Thank you thank you

Edit: step 3 indicates nb1 safetrap but would I have already "downgraded" to Mk2 tho ?
