[Q] Specific information about flashing 4.3 DN3 on N7105 anyone? Got a bit confused! topic

Hey everyone, I tried to search different threads, lots of places, but could not find anything specific.

Can anyone help me on this thread? This one: http://forum.xda-developers.com/show....php?t=2541860

I have a N7105
JediX19
OS 4.1.2
Boot Loader N7105XXDMC3

I always used ROM Manager to install new ROMs. No secret there, just download the zip to sd card, wipe everything, and boot the new ROM.

From what I read, this ROM needed the following:

- 4.3 bootloader
- MK5 Kernel
- TWRP to flash it

Can a good soul help me on the steps I should do coming from my current ROM?

Couldn't I just do the ROM manager way to flash this new ROM?

I did not get the steps necessary.

Sorry if there is a thread somewhere like this, I really tried to search. Thanks alot everyone.
