I am making this thread because I took the OC1 update while rooted and I am asking more experienced members what I should do next.
I mistakenly took the OTA because I had read somewhere that some users upgraded from 4.3 to 4.4 with root from the OTA. I was wrong.
The OC1 OTA removed my root and prevented me from upgrading to LP. I have flashed other kernels and tried everything. I have read every thread in this forum on the topic and I see it mentioned that if I did take the OTA that I no longer had root, but I have found nothing else.
It is my understanding that after taking the OTA that I'll never have root again. Is there at least some way to get my phone completely back to stock and on LP?
Yeah I know it was a rookie mistake and I shouldn't have been so rash but I am here now and I don't know what to do, even after sifting through all the threads about Verizon's LP OTA.
Thank you for all of your help in advance.

This causes a boot loop.
However, I was actually able to towelroot on NC5 before the phone restarted, so I am now rooted again! When I encountered this boot loop the first time, I just went back to NK1 instead of trying to towelroot in-between reboots.
I probably could have also cleared cache before reverting back to NC5. Thanks for the help!
If the LP update failed then you were not on OC1. There were two updates. The first was still KitKat NK4. The second was OC1. Those that were rooted were able to take NK4 but the OC1 tended to fail. So there is probably still hope.

I had a similar issue , but I flashed the stock 5.0 ROM using Odin on my computer, but now when I try to flash back to NK1 it softbricks it.
I was able to to flash it back to the stock 5.0 ROM using Odin. I guess there's no downgrading after I did what I did....
Yep, Stuck on the new Lollipop. No root insofar as I know of.
sucks
My replacement s4 came with 5.0.1 on it. Very disappointed with it!!! It's driving me crazy. I can't even see a notification in the top bar smh. All it says is Verizon wireless. I miss root and roms so bad (
So just to be clear.
There is literally nothing i can do to downgrade if i have taken the OC1 OTA on the SCH-I545???
No going back to Kitkat on Verizon S4??
And no root?

I could be entirely wrong, but after some conversation with @klabit87, I think we've found a useful little tidbit for people wanting to have root for NC5 and who have either just purchased a S4 with NC5, or have accidentally or intentionally taken NC5 OTA update and then find they'd like to have root on NC5. You just have to downgrade your bootloader from NC5 to NC2! From there, follow @Surge1223's instructions for downgrading from NC2 to MK2, get MK2 and root with saferoot, and then use @Surge1223's instructions for upgrading to NC5 with Root.
I apologize to the moderators and devs if I'm entirely out of line in posting this, and won't be offended if this thread is locked or deleted.
I think you lost me
It is my impression that NC5 OTA can downgrade to MK2 without needing root access via Odin.
From there root MK2 and move up the process to prerooted NC5.
I'm pretty sure on that. Anybody can downgrade via surge's method, rooted/unrooted.

If I've read @Surge1223 thread correctly, the tars are modified with different bits removed.
OK I am new to the android world and also to rooting, Ai was thinking about it before I took the update so? Is it possible to still root with the new NC5 build or are we still waiting ? If it's possible can anyone point me I. The right direction, to read up on ?
Does this require the wifi fix after reupgrading to rooted nc5? Thanks for sharing!

How does one go about downgrading, is there a thread somewhere I can look at?
That's what I asked.. guess I'll just wait till one comes available.

Sorry for the dumb question, but are we able to install safe strap once we've downgraded to mk2? Or are we stuck with the nc5 bootloader?

I rooted my i545 over a year ago. Have not been able to get any update since, and everyday I can only postpone the Samsung update (won't update because its rooted).
Now I'm tired of rescheduling everyday lol.
4.3 Mk2
I dont know what the knox status is, do I start there with ODEN?
Phone is crazy slow and cluttered. I want to backup and erase everything on there and start over.
All I need is a basic touchwiz based ROM
Thanks in advance!

Download the full wipe nc5 and Odin from here:
http://forum.xda-developers.com/showthread.php?t=2735172
That will get you to stock 4.4.2. If you still want to root after upgrading, download towelroot. NK1 is the newest firmware right now. There is a thread to upgrade to NK1 and keep root but for some reason I can't pull it up.
What bootloader are you on? Anything over MDK do what Hightower24 said.

Odin Files here just flash the stock room you are on and you should be able to use OTA

Okay here's my tale of woe..
I rooted my phone last year - but at some point - took an update and lost root.
Though the phone still displays the "custom" boot screen with the padlock.
I tried to take the Lollipop update through the OTA but it fails and I get the "laying on his back" failed Android dude...
The phone DID take the first update.
I have: wiped cache in recovery, wiped data and cache in download manager.
No luck.
I have tried loading the NC5 kernel back on (via Odin 3.09) - but that makes the phone 100% unstable...reboots every 3 minutes..no access to apps - they lock and reboot etc etc.
Loaded the NG6 kernel back on to re-stabilize the phone and tried to Kies the update.
Kies downloads the update then when it tries to apply it the phone boots into "download mode"
I have been advised to:
I had the same custom boot screen--even after unrooting. Tried using Triangle Away to reset the binary count, but the count was already at 0. So ultimately I had to re-flash the NC5 kernel via Odin to get things truly back to being recognized as stock.
Then updates started rolling in for NG6, then NK1. Finally the two-part update for Lollipop.
Click to expand...

and - of course that doesn't work. NC5 won't let the phone run long enough to take an update..
It has been said:
Try to flash the OC1 with the pit file
Click to expand...

But I haven't found the stock OC1 file anywhere to even try and begin to get it loaded.
Honestly - I'm not even really concerned about rooting right now. I'd really just like to get the phone back to a stock configuration and kernel and lollipop.
Developer mode is enabled. Obviously both Kies and Odin talk to the phone with no problems.
Any ideas ?
Thanks, Dan
Get your phone to 4.4.2, use the verizon software upgrade assistant program preloaded on your phone to update. I had this exact same problem and that's how I got to 5.0.1
You WILL lose root. And there's no method to root 5.0 right now, and people have been saying that there might never be. You also won't be able to downgrade, or at least there's no method to do so at the moment, so you will be stuck with lollipop for a while, maybe forever.
Yes.
Maybe I need to clarify.
I do not care about root at this point. I just want to get the phone back to a stock state and take the Lollipop update.
I'm curious as to why I will never be able to update beyond Lollipop.
Doesn't matter I guess - the phone will have been replaced by then - but still...why ?
Thanks, Dan

I've downloaded (3) different 4.4.2 Firmwares.
FNK1
FNC5 (No Wipe)
FNG6 (No Wipe)
Any opinion on which one is best ?
Did you download these manually or OTA? When I re-flashed the NC5 kernel, I received NG6 then NK1 then the 2-part Lollipop updates all OTA back-to-back.

I would use the ng6. That's what I was running.

Hmm... I'm not sure if it makes a difference to download OTA instead of manually. I would think it's worth a shot flashing NC5 (if it will let you downgrade) and using the software update feature to update OTA the rest of the way.

Got it finally !
started out by flashing (FNG6 (No Wipe)) in Odin 3.09
That got me to regular boots with no "custom" screen showing the lock symbol.
Then I had to take OTA updates to FNK1 then the OTA preliminary Lollipop update then (OTA) finally Lollipop itself.
No root - but that's OK.
It took about an hour and a couple shutdowns to get things running smoothly but it's all good now.
Thanks everyone for their help.
This was rooted a long while back and now with the OTA update I have i545vrufnk4 baseband version but I can't install lollipop. I don't care about lollipop I just don't want to be prompted to install it when it doesn't work (thanks knox).
What are my options? Odin? Rooting? I tried towelroot and it didn't work this time around. please help

Well, nk4 doesn't have root. NK4 is the first step to lollipop. The qfuse isn't blown yet, so you can full wipe back to nc5, get root and safestrap. You can't disablet he update thing without root, so you have two options:
A)Odin back to nc5, then disable the OTA
B)Live with the notification
-I believe if you hold on the thing, click on settings, and disable the notification, that will stop any popup. I haven't done this in a while though.

When I turn on the phone it shows custom with the unlock picture so I thought that meant the fuse was blown. I
No, it won't tell you if the qfuse is blown. That just means it detects root access on boot, and the system status is unnoficial
Just downgrade to NC5. There is a thread for that. Install towelroot and then using TB, freeze SDM. Good to go.

Towelroot doesn't work anymore for me. It did once but now it fails(this phone isn't currently supported) and I tried several codes. Is there something I should know before I try odin?
I guess what I'm asking is why do I need to root?
Secondly, does odin no longer work if I upgrade to lollipop down the road?
What firmware should I put on this phone?
You will have to use Odin to go back to nc5, with a FULL WIPE
Then, you have several options:
1)Use the stock deodex lollipop with Root
2)Echoe ROM v49(no dev though, so no more updates)
3)Super6(s6 port)

I saw something about that, I was reading the Odin guide where they said after odin shows the green "passed", then you need to reboot the phone holding the power home and volume up keys and pick the "factory reset / full wipe" option. if you don't do that does that brick the phone?
appreciate the help, it's my first time but I'm picking this up quick
No. The Full Wipe will wipe it for you and it will automatically reboot the phone. It will be in an "out of box" state.

Oh then if I were to do a full wipe, then I wouldn't need Odin? That would take me back to MK2 from back in the day?
no. If you get the nc5 file, it will upgrade/downgrade you to nc5, which is 4.4 Kitkat

I'm sorry I just feel like I'm missing some key concept here.
So just to clear up my understanding here are the following firmwares avaiable for my galaxy s4 i-545
i545vrugOC1 5.0.1
i545vrufnk1 4.4.2
i545vrufng6 4.4.2
i545vrufnc5 4.4.2
i545vruemk2 4.3
i545vrudmi1 4.2
My phone says it's running VRUFNK4. I'm guessing that's the temporary OTA (1/2) upgrade.
Am I right?
Is that why you want me to flash NC5 and is that why if I do a factory reset using the home and volume keys it won't do anything but just keep me where I am now? Why not an NG6 or an MK2 for that matter?
I'm sure a lot of people have these questions I just can't find it anywhere. I just don't want to brick my phone (is that permanent?)
nk4 is part one of two yes.
Even if you do a factory reset, it still won't update because you once rooted, and knox takes note of this, and will block any OTA. nc5 is the last firmware that had towelroot working. ng6 doesn't work with towelroot. I don't see why you would go any further back since the ROMs are based off of nc5.

Ok that makes sense, I thought for a minute the phone wasn't capable of going back to an earlier version because it had a different boot loader? is that not the case?
That is only the case once you go to 0C1. It is not the bootloader. It is because a physical qfuse is blown, and it has two values, 0(unblown) and 1(blown). If it reads as one, no going back to an older version.
Apologies as I searched for the last two days, and still not sure I have the answer to this.
My phone did the automated update to NK4 this summer. It then failed to do the upgrade to 5 or 5.1. I made the mistake of rooting it, thinking I could just put a custom ROM on, but (if I'm correct) that's not possible from NK4?
Assuming that is correct, is there any way to fix my phone so that it will do the stock update? Everything I read says that once I'm rooted, there's no way to do the stock update. True? Did I screw myself?
Right now my phone is running VERY buggy with seriously reduced battery life. I need to do something.
thanks
You can Odin to nc5 and root with towel root. If you want to keep root don't ota use a method that doesn't upgrade bootloader past nk4 like muniz.
