Not that it means a ton but I flashed the ME7 modem about a week ago and have noticed slightly better signal strength both at work and home
DO NOT FLASH IF YOUR ON MDK AND WISH TO RETAIN YOUR CUSTOM RECOVERY! THIS WILL REMOVE THE LOKI EXPLOIT!
This is a new update for SCH-1545 taking users to VRUFNC5. This is the stock factory image. Also, If you need to go back to stock for whatever reason and this Odin tar doesn't work I suggest using the VRUFNC2 factory image from sextape instead.
For the sake of simplicity, I've also included a mirror to the MJ7 and MK2 "emergency" Full-wipe Odin tars as well MJ7 Full-Wipe and MK2 Full-Wipe
@Tomsgt made a great video of the process that can be viewed here
Information:
1. ROOT METHOD can be found here
2. Otherwise, Download Odin 3.09 here (Note: Bootloader = BL , PDA = AP , Phone = CP)

Full Wipe ( AKA Emeregency Repair)

2. Select the tar.md5 in Odin under PDA (or AP if using Odin 3.09) and keep Odin's default settings
3. Extract the PIT file from your phone or Odin tar, also I've uploaded it here just in case.

Surge - thanks for posting the NC5 tars! Anyone have access to a 32 gig model .PIT? I've tried to extract mine using Heimdall but it refuses to work, so if someone has the larger pit file I'd appreciate the help.
Edit: Never mind I opened up the factory wipe tar and extracted it.
Awesome work there @Surge1223. Upgraded from the NC2 leak to NC5 using the no-wipe file. Absolutely no issues or errors (finally). Now, just waiting for the OnePlus to officially release so I can throw my money at 4 of them and sell the S4, and possibly leave Verizon in the process.
Guys, if we flash the NC5 tar and the phone boots normally, will we be able to downgrade to MK2 after we test it, and most important, will the actual root for MK2 still function?
I would like to try the rom, but then come back to MK2, root, ss and restore my backup .
Thanks.

Dumb question...If we have this, why don't we have a rooted flashable ZIP? I assume these are similar to disk images; are we essentially waiting for someone to extract the proper bits from said images then build a flashable zip from them?

Surge has this. From another thread in the "General" section, he is holding off releasing it to avoid all the questions and confusion since it seems so many people are having difficulties with his pre-rooted leaked NC2 release and pounding him with problems and questions regarding that.
I completely understand his position on this even though I eagerly am awaiting pre-rooted NC5 myself. I had little problem doing the upgrade to his NC2 ROM coming from Hyperdrive and MJ7 personally, but others have had grief for some reason.

Same here. I did have some difficulty and had to improvise a little but I referred to the instructions for the NC2 upgrade and eventually managed to be on NC2 with Safestrap. Solved my problems on my own with the information that was already available.
so to be clear, if i use surge's Upgrade to 4.4.2 and keep root method to NC2. Then can i use the NC5 odin.tar NO-WIPE file to upgrade to NC5 and retain root?

Before you start doing anything to your phone, find what build number you have. To do this go to settings >> more >> about phone. Then scroll to the bottom and find build number. Remember the last 3 characters of it because it will be referred to things across the forum.
I nor the devs who created these threads are responsible for anything that may happen or happens to your phone as a result of rooting, flashing, etc. You are choosing to do this yourself and therefore assume any/all risks involved

Safestrap
Since the bootloader is locked and the loki exploit is patched. Only those on MDK can have a custom recovery such as TWRP or CWM to flash almost anything on their device. Those who are on a build above MDK (ME7, MI1, MJ7, MK2 and NC5) can only use SafeStrap to flash touchwiz based roms. DO NOT ATTEMPT TO FLASH A CUSTOM RECOVERY ON A BUILD ABOVE MDK. We can't flash custom kernels so we can't flash roms like CyanogenMod, and AOSP, they require a diffeent kernel. Safestrap requires root. Install safestrap as a normal apk. Thanks to @Hashcode, Without him it would be impossible to flash any custom ROM on a locked bootloader.
VZW Safestrap thread
If you are on ME7 or MI1 you can use Safetrap 3.65 to flash 4.2.2 touchwiz based ROM's in ROM-slots. I recommend you update to MK2 and install Safestrap 3.71
If you are on MJ7 of MK2 you can use Safestrap 3.71 to flash 4.3 touchwiz based ROM's in ROM-slots. Heres a list of compatible 4.3 ROM's
If you are on NC5 you can use the @muniz_ri's SafeStrap 3.7.5 to flash 4.4.2 touchwiz based ROM's. Here's a WIP list of 4.4.2 Compatible ROM's NC5 Modules

Saferoot will work at least on ME7 and MI1. Probably also MDK, but I wouldn't recommend mixing that up with the Loki work.

I've read up a bit, but havent been able to confirm something and was hoping someone might be able to help...
Right now, I am on 4.3 MJ7 rooted, and want to upgrade to 4.4 NC5 and then root. I don't care about flashing ROMs, just want root access...
From what I can tell, I have two options,based on what I have done in the past
1) I can ODIN a no-wipe 4.3 MJ7 on my device, so then I can OTA to 4.4, and then root via towelrool
or
2) I can use ODIN directly to 4.4 and then root.
Is there any difference in the end result between the two, or will they get me to the same spot? Also, the link for the no-wipe MJ7 (at http://forum.xda-developers.com/showthread.php?t=2507217 ) seems broken, so unless someone has an updated like, I may have to just do #2 anyway.
Thanks for any help

PP now supports the S4 and I would like to return the phone back to Verizon original condition. I have a stock rom and I believe with a stock Odin will work without tripping Knox, but how to I flash the lower information that I used Odin to get it on PP to begin with that doesn't change with a rom flash. The person also said that the 4G information is missing and that needs to be re-installed. There probably is a post here, but I have had no luck in finding it.

Hello everyone,
I'm looking to flash my Verizon S4 i545 for the first time. I have the NK1 Build on it. So far, I've rooted it with towel root and have safestrap 3.75 installed.
From doing my research it seems that having the NK1 build prevents me from flashing some roms such as CM11. All I really want from my s4 (had it since launch) is to have the best performance and battery life possible. I'm not looking to do anything fancy beyond that. From some online reading, it seems Hyperdrive might be the best rom for my needs.
How can I go about installing the Hyperdrive rom? (which version should I look out for considering I have NK1)
What precautions should I take before attempting to install?
What other custom roms can I install onto my S4 NK1 build?
Thank you in advance!
I hace the same thing, and muy SE is enforcing. I dont know if that is important.

Honestly, you should downgrade back to nc5 from this thread: http://forum.xda-developers.com/showthread.php?t=2735172 You won't be able to install any CM or AOSP rom since you're not on mdk. Hyperdrive is a good rom. Echoerom and Eclipse are solid as well. They're also based on nc5 and you'll likely not have too many problems if you downgrade back.

If you use the full wipe nc5, it shouldn't be buggy. It's like having a clean slate. For myself, I've always had better success from nc5 than nk1.

For me it's just preference. Most roms are nc5 based. There are modules and fixes out for those on nk1, but for me, I have always had issues with it. Downgrading to nc5 eliminated the problems. You still need to flash modules and wifi fixes, but I find it to be far more stable. No, you don't need to be rooted to use Odin. If you do plan on downgrading, I would suggest the full wipe. Some have experienced issues with the non wipe. Hope all this helps.

You can use SuperNexus ROM. It works with safestrap. You can also use Kitpop ROM.
