[Q] Why does the MK2 bootloader matter? - Verizon Samsung Galaxy S 4

Probably a noob question, but if you want root for titanium, wifi tether, xposed mods, etc...
Why is it so important to stay on MK2.
There's a few threads on downgrading from NC5 to MK2, and back up to keep the MK2 bootloader.
MK2 is not MDK, you can't run a custom recovery.
So what's so bad about taking the NC5 OTA and then just rooting? You can still run SS? Can yoi not flash a SS compatible ROM on NC5s bootloader?
Just trying to understand the difference. I know the benefit to MDK, just not anything else.

People hold out hope that someone may unlock the mk2 bootloader. To me it doesn't matter I'm on the NC2/NC5 bootloader myself.

Are we pretty close to unlocking MK2? Should I hold out?
I used your method to upgrade to NC5, but the audio over wifi glitch has me on the verge of taking the OTA.
Im not really seeing any other way of fixing this issue except going stock?

Also alot of those threads were made before a native NC5 exploit was released. Before towelroot, the MK2 bootloader downgrade was the method for root.

It really sucked having to do that. It was my first root ever and I soft bricked my phone three times because I knew less than nothing about rooting and whatnot. Three weeks later: Towelroot. Now its a party lol.

But there are more devs working for a bootloader exploit for the S5, than the S4.
And the S5, so if there is an exploit on the S5, it will probably transfer over to the S4 at the NC5 level since that firmware is on par with the S4s NC5.
So isn't it better to go to full NC5?

You may have to flash me7 in odin if after you do all that and it still doesn't let you take the ota. Just a heads up. Some had no issues and others still did.
All of the current basebands have a method to root and a safe one. Just once you get to mk2 stop there.. There's no guarantee we'll have a root method for whatever is coming next.

Easiest way to upgrade to 4.4.3

Hi, my wife has my old rooted S4 on MK2. It has been debloated so I know the update will fail. I don't want to do safestrap. Do I need to Odin back to a clean MK2 and then accept updates, or could I Odin the stock Kit Kat factory image?

It's my wife's, so not using bootstrap, so what am I losing, besides some potential that they ever crack the bootloader?

I am currently rooted on MJ7 and do not care if I lose everything in the upgrading process.
Is there a post somewhere on upgrading straight to NC5? Do I just do a normal odin flash of the NC5 update then use towel to root?
Or could I just take the OTA then use towel root? Or to do that do I need to properly unroot, take OTA, then root NC5 with towel?
*EDIT*
I am assuming I could just follow this to do a full wipe to NC5? http://forum.xda-developers.com/showthread.php?t=2735172

Really, How did you keep the mj7 bootloader? the article stated to downgrade first.

it doesn't say anything about downgrading first.
there is a method to downgrade back to mk2 if necessary.(which is not anymore)
but that is at the bottom of the op
and this process doesn't upgrade the bootloader so it never touched it.

Of1... Am I stuck??

I have a Verizon S4 that is currently running Lollipop OF1.
I have heard that root and custom recoveries aren't installable with this update, and this update is not downgradeable. Is this true?
Yes, all of that is true.
From what I've seen, some users have achieved root but you are right on not being able to have custom recovery, only users with the MDK bootloader can install recoveries. Downgrading is not available either. I recommended taking some time and reading through the forums and educate yourself on what you can and can't do.
Edit: Looks like root is not available yet, I have MDK so I don't really look into it much.
