I'm thinking about how i want to go about having my ICS experience when the GSM OTA finally arrives. I've decided i want to start with a totally unmodified ICS phone. z Will voodoo temp unroot, then immediate factory reset give me a completely stock phone? I've never flashed this GSM phone, only routed and OTA updated to the latest 2.6 from Moto.

No, it will not, as the system doesn't wipe everything, it just wipes data. To unroot:
1. Download SuperSu from the market.
2. Delete Superuser from /system/app
3.Go into Supersu and in the far right, select "Permanent Unroot".
You're unrooted.:good:
Thank you!
I accepted the OTA for NC5 for my phone awhile ago and I would like to get warranty service on it because the screen is flickering. Does anyone know how to unroot the NC5? I rooted using safe strap and downgrading the system sans kernel and re updated with the rooted version of 4.4.2 I searched and could not find any guides and I was not able to find any original stock OTA upgrades to re flash Verizon OTA that they sent out before. Does anyone have any locations or ideas on how to undo the root? For giggles I did try the whole get rid of supersu from the system folder and uninstall supersu.ya that works for all but 5 minutes until you factory reset and it is built in. So I at least gave it the college try... :angel: Any suggestions or possible solutions?

Flash a factory stock ROM image using Odin.
Hey Guys, Yesterday i made a Factory Reset because of some stability problems. Now there is no OTA for the newest Firmware. What can i do without Root?
Thanks
Factory reset wouldn't get rid of OTA if you previously already updated.
A friend of mine has a Verizon GS4 and is trying to run the OTA update, but for some reason his device status is Custom so the update won't go through. He's fine doing a factory reset. Are the Lollipop files available yet, and, if so, is it possible to flash them without being rooted or having any recovery installed whatsoever?
Basically, can a Verizon GS4 have 100% stock Lollipop flashed over an existing 4.4.2 installation without custom anything?
lollipop files aren't even out yet, nobody captured the ota
best to probably odin back to a 4.4.2 ROM so you can start off clean
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
bump
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.

That was the process to freeze OTA

Does the phone need to be rooted to use odin? I saw a video on rootjunky where he does it pretty quick and easy (https://www.youtube.com/watch?v=GL8XwuRYoWU)

Root not required to odin.

You just need towelroot

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.
