Upgraded to NK7 from NK2. Lost root. - Verizon Galaxy S 5 Q&A, Help & Troubleshooting

Hello
Last night, I accidentally pressed OTA update button, so my phone got upgraded to NK7 from NK2.
When I had NK2, I followed this thread http://forum.xda-developers.com/showthread.php?t=2784880 to have root on NK2 before.
Now I have NK7, lost root, still KitKat 4.4.4(not lollipop), but have no idea how to downgrade back to NK2 w/ root or keep NK7 w/ root.
So, my question is,
How do I get back to NK2 w/ root OR keep NK7 w/ root?
I don't want to lose my data on my phone.
Is there any way to do this without flashing it back to stock NK2?
Thank you in advance.

Install towelroot and supersu first. Then, flash the NCG kernel. When you reboot, ignore the force closing apps and run towelroot. Then run supersu and let it install itself and disable knox. Reboot, flash NK7 kernel.
If you are using kitkat, please use safestrap and spare yourself the trouble.

Also on nk7. Really no desire to go to Lollipop just to enable wifi tether.
Is there a link to safe sources of the kernals needed?

[Q] Tried to Root NK2 Verizon, Stuff Is Broken. What Did I Do?

Alright, so I picked up a new S5 from Verizon today running NK2. Played with it a few hours, and I wanted to get it rooted and BusyBoxed and debloated. So I follow the instructions I find here: http://forum.xda-developers.com/showpost.php?p=53447942&postcount=1
Followed all instructions to the T, and when I Odin'ed it back to NK2 (Step 7) and rebooted, WiFi no longer works and random apps force close.
Is there a different/better method for getting rooted once the phone is on the NK2 firmware, or should I just Odin it back to stock and live with it?
I'd appreciate the help. I'm coming from an S1, 3, and 4 which have had many many many ROMS on them without issue, so I'd like to think I know what I'm doing.
Also, if I do Odin a stock version, should I do NK2, or is there a more "Open" firmware better for rooting?

It sounds like you have your firmwares mixed up. Try to Odin back to the full stock NK2 and re-root or Odin back to NCG, root , safestrap and use the stock rooted ROM in my sig. Just make sure you follow the install instructions and use the NK2 firmware in the ROM post. As long as you are rooted and have safestrap you should be able to install the rooted NK2 ROM and then the firmware without having to flash the full stock tar. That would be the easiest way.
I got it back to stock NK2 firmware, Odin'd NCG kernel, TowelRooted, SuperSU and Busyboxed, Odin'd NK2 Kernel, runs like a champ. Now if I can just get my SD music to work correctly, I'll be all set! Thanks!

[Q] NOOB trying to update MK2 firmware to Lollipop

As the Title states I have been trying to flash to Lollipop using the thread Update to lollipop and keep root using Flashfire app. I have downloaded and followed the procedure (yes I am rooted and confirmed with RootBasic) with it failing.
What happens is I load the files in order stated per the guide hit the lightning bolt, does the reboot and then gives error no command and then sits at stock flash update where you can either reboot, flash file or few other choices. I have tried numerous times with each time same result. What is going wrong? As I stated on am on MK2 firmware with ATT update frozen so not sure why this is. When put in download mode I confirm Knox 0 and Offical software with it having 0x30 for bootloader. Any suggestions or should I ODIN update but with what?

We just discovered this morning on the Vz S4 that FF does not function properly on their MK2(4.2) firmware which is likely also the issue here. You will first need to update to KitKat using the following file then root with towel root before updating to 5.0: https://www.androidfilehost.com/?fid=23501681358548937
Before I proceed to KitKat with file linked to is there a guide to properly performing this and then rooting? I will update from MK2 to NB 1 then I need to root, then do the FlashFire and Lollipop undate. I see the guide to use ODIN but then I will have to root I also have not used towel root either so any guide would be awesome. This should not change KNOX either correct (although I guess it does not matter since I am long out of warranty)?
I want to have a clear understanding of procedure so I don't brick the phone! I have not used ODIN before since I haven't really done much rooting other than when I first got the replacement phone last year
I'd suggest [GUIDE]Odin to Stock, Updating, Rooting, and Installing Safestrap by guut13, and of course [How-To] Update to I337_OC3 - 5.0.1 and KeepRoot (4/7/2015) by muniz_ri for rooted Lollipop. Look in the I337 General forum for both.
Thanks Creepyncrawly and muniz_ri for both of your help it was easy to update from MK2 for this noob!
Ok I followed the guide and did update to stock nb1 and rooted, used towel root and then used flashfire to Lollipop and all seems to be working (I still am in process of setting phone up but it is running lollipop).
Since this is oc3 rooted is there anything else I have to do such as freeze att update? Anything else I should do right away?

[Q] coming from s4...little confused, some root questions

im on 4.4.4 NK2. from what I gather, best way to go is root from what im on now and not take the lollipop update. just want to make sure that is correct and that this is correct way....
1. Flash The NCG stock kernel via Odin
2. Reboot & Root using Towelroot
3. Install SuperSU, open the app and allow it to update binaries normally
4. Flash NK2 kernel via ODIN
after that, is the newest lollipop update worth taking? i heard there was problems.
also, i see that there is FlashFire beta....i know its basically mobile odin....is safestarp still necessary to flash roms or can i flash them via FlashFire?
thanks in advance!

Looks like you have it right. If your phone is new to you you might consider flashing the full wipe NGC tar file and starting from scratch. Good way to get rid of any junk that might be on your phone.
You can flash with flashfire and go up and down and keep root easily and without using odin. In my opinion, it's still good to have safestrap. It is the only recovery available to you. I still run 4.4.4 on my S5 though I haven't tried the very latest lollipop that came out. I'm fine running RicksRom.

Galaxy S4 How to unroot?

I rooted my AT&T Galaxy S4 running Android 5.0.1 using kingroot and it worked great. I proceeded to try to install a custom ROM, which failed and I never even overwrote the stock ROM. So I am currently using the stock ROM. I recently got an update from AT&T for the stagefright patch, but every time I try to install the update, it puts the device into a secure boot download screen. I have to reboot the device to get back to Android. I also tried factory reset but it also causes the secure download screen to show up. I want to trade in to upgrade soon and I need to know how to fix this. Thanks!
Ok, if you want to get the stagefright patch and still be rooted, follow directions here with the stock rooted rom. http://forum.xda-developers.com/gal...-to-update-to-i337oc3-5-0-1-keeproot-t3075814
After the flash, don't install or flash anything else, update with the OTA from AT&T. If you want to remove the custom padlock nag, use triangle away from play store.
If you just want to get it completely stock, Odin to stock NB1 by following directions in this thread. http://forum.xda-developers.com/showthread.php?t=2616221
You can take the OTA updates after that but only one every 24 hours. It'll update from NB1 to NJ4 first. Not sure how many updates get you to OC4 4.
Snapping along on stock rooted 0C4 I337, wishing for some good up to date lollipop ROM's to throw into flashfire
Thank You!

Thank You so much! I was having a hard time finding a solution! I appreciate it very much!

ROOT question!!

Ok say i have kitkat 4.4.4 and cannot update to lolipop via System Update because my root was messed up due to earlier update. I want to know if i can update to lolipop using Odin and obtain a root for it. i am on stock kernel now with root and i was wondering if it will work before i flash back to 4.4.
If you use odin to flash you will loose root and any custom recovery you have installed so you will have to reroot etc after upgrade.
