Hi everyone.
Is there any way to root the Note 2 N7100 on Samsung official firmware Kitkat without tripping Knox. ??

My bootloader is ND4
My baseband is ND3
My PDA is ND4

If there is a safe method, what is it ...

I tried TR but got that my device is not supported.

My Knox is 0x0

If there isn't & I must trip Knox to root, so what's the best & safest method for rooting my N7100?? My warranty is gone long time ago anyway.

And if I'm gonna trip Knox so I prefer to have a custom recovery, what should I use? I thought of TWRP but found some complaining that 2.8.6 caused loss of signal... What should I use??

One more question, please.

Will rooting my phone & tripping Knox prevent future OTA update to the long awaited official Samsung Lollipop??

If the answer is yes is there a way around it ?? Will I be able to flash it by Odin after getting it from any where like Sammobile ?

Sorry for being long & Thanks
