Accidentally upgraded to OF1 Help downgrade to OC1 - Verizon Samsung Galaxy S 4

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.

Sorry my bad stang5litre I said only Muniz roms bad statement all ROMS in Xda are capable of..downgrade,
Stock ones came from verizon directly not... Several people had the problem when they jump from kitkat to lollipop even though they were rooted took the one from Verizon OTA and they can't written to previous bootloader, if he took upgrade from Verizon no way turn back... As far as I know if he installed from xda Rom yes incluide yours rom that is really nice indeed

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]

Junk ...... Deleted

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...

Unroot Question

I rooted my Verison Galaxy S4 before they updated the bootloader to ME7. If I wanted to unroot my phone can I follow the ME7 unroot instructions to update to Android 4.3 bypassing the update, or do I have to go back to what my phone was originally prior to updating?

Just. Don't. Do. It.
You have MDK Lokied bootloader apparently. If you take Verizon update they will ruin that! Wait for developers to incorporate the best 4.3 features in custom roms.

No bootloader unlock exists, you can't run AOSP roms. There's multiple 4.4.2 TW roms in the android development section
Is the 4.4 ota update worth it or not really ? Says there is better battery and faster. But is it worth no root ?

my understanding that unless u are 100% stock and that means NO root, the OTA will mess up.

There is currently 2 aosp 4.3 roms for safestrap. Although they are very buggy.

Not precisely. You can be rooted but otherwise stock and manage to take the OTA successfully. That will leave you unrooted.
My phone was rooted factory stock and would have taken the OTA successfully if not for a single modified file left behind by an older version of SuperSU and a file modified by Safestrap. If Safestrap wasn't active and without that old SuperSU thing it would have taken the OTA.
From a practical standpoint, you're right. Unless you're stock, there's a good chance the OTA will fail to start. And keep nagging you each time it fails.

If you are on MK2, than you have a locked bootloader, which as of today is STILL UNLOCKABLE!!!!
Therefore, there is no AOSP ROMS avaiable for us, SafeSTrap users, which means that we can only flash TW based ROMS!
there are tons of ROMs for us, SS users, and the first 3 ROMs that pop into my mind which are the best of the best for us i337 AT&T users with MK2 locked bootloaders is these:
SHOstock-i v7.0 ==> http://forum.xda-developers.com/showthread.php?t=2468860

I have spoke of surge's upgrade/downgrade methods before. He is a senior member here on xda. The other method I know of, as far as upgrade/downgrade, is giglies. Giglies method came out after. It's fewer steps but the documentation could use an overhaul. If you see a post around the s4 forums with surge's name on it, I bet a lot of people are going to see what he has to say about it

with towel root now available for use on NC5 phones, the need to upgrade/downgrade really is no longer a driving force.

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?

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

[Q] Why does the MK2 bootloader matter?

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?

How root NG6

The phone took update and I jus got it working earlier. I had to Odin back to NC5 cause wiped whole phone lol. Not familiar with NG6 so needing a point in direction. Thanks in advance

Your best best is to downgrade to NC5 or upgrade to OC1 but be cautious once u take the update to OC1 android 5.0.1 THERE IS NO GOING BACK DOWN!!!!! but OC1 has root wit kingroot and NC5 wit toowelroot but NC6 not that I know off. I used to have the rom the rooted version of NC6 because I was capturing the OTA updates. So anyways u can choose if to downgrade to NC5 or update ur phone to OC1 to lollipop 5.0.1 to gain root back.
