I just used the tut to upgrade from MI1 to MJ7, worked perfectly! I really want to get on to KitKat is there an official method to do so?
This is the method I used. And I still have the mj7 bootloader.

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.

I know going from ME7 to MDK is damn near impossible, but how about MJ7 to ME7?

do you have anymore info on this? and why it would be beneficial? i want to run a different ROM but dont want a dual ROM like what safestrap requires...Does MJ7 have an unlocked bootloader yet?

It's not beneficial, just possible. And no
Is it possible to downgrade from MK2 to something else like the one before it? I have had no luck w/ my search.
you can downgrade to mj7 but there's no advantage to it. that's it

I've been hearing chatter that MK2 has some / might have (its) "exploitable paths" patched. So MJ7 would be more appropriate.
there's a safestrap version for mk2, just as "exploitable" as mj7

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?

If you don't care about retaining mk2 bootloader odin full wipe NC5 and use towel root for root access...

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

yes that is one way of doing it
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?
I am having no luck downgrading the software on my verizon S4 to OC1 from OF1.
I used odin 3.09 and odin 3.10.16 with it failing.
Any advice would be greatly appreciated.

That's because once the i545 is updated to OC1 there is no way to downgrade.
Usually the Odin flash will fail with a message similar to :
Fail (Auth.)

so thats a solid no to downgrade even from the micro update
To the best of my knowledge the i545 is very unfriendly when it comes to downgrading bootloaders /firmware.
The only S4 model that I know of that is downgrade friendly is the i337.. Infact I know from experience that it can be downgraded from lollipop back to kitkat with a simple odin flash.
The only way a microupdate can be Downgraded is if the bootloaders... Which include TZ (trusted zone) are practically the same and only system files change... But this is rare with Verizon phones specially after Knox.
Two things... There are threats of Verizon s4 that warn about update OTA, no way to return previous bootloader my friend... muniz roms are the only capable of cuz they don't update bootloader I did recently downgrade from of1 to nc5 with no problems.... S4 must be deactive OTA, if I could I would return to MDK bootloader unfortunately when I receive this was already in NK bootloader.... That's Verizon....

The I545 can be downgrading just like any other model but only to where you rooted it at. So me MDK. I can go all the way back to when phone was purchased. Nk1 they would be able to revert back to Nk1 and so on. If you took the OTA then your bootloader got upgraded. stang5litre 5.0 Edition doesn't upgrade your bootloader.

Incorrect. My rom doesn't upgrade your bootloader. Read comment I left above. Where ever you are rooted at is where you can go back 2. Plan and simple. My ROM doesn't update the bootloader.

I'm afraid there is nothing you can do if you took the update. As far as I know it patches all root methods. So If your on OF1 from Ota by Verizon they upgraded your bootloader and now your stuck with stock verizon without Root. [emoji45]

To down grade to previous versions........ the only way that can be done is if you have the OC1 .pit file (mapping file) and the other files ...... without the .pit file it cannot map to a previous version.
In other words......... without the .pit file it cannot be done ........ Sorry

You could flash the 0c1 kernal in odin and the use mobilego to root.
However i cannot apply any custom roms without soft brick/bootloop. Still trying to get xposed working...
