now i am on optimal 15-5
If You Are Rooted And Bootloader Unlocked You Can Get NI2 ROM At Least That's The Earliest I Have Gone But There Is More Than Likely An NCG ROM Out there somewhere download links don't work anymore is my main issue I have run into
you can get NCG stock firmware installed by going to brens123 guide I booted NCG on pb1 bootloader on xda under s5 Verizon forum whether you have bootloader unlock or not
you have to have root though and supersu installed
thanks i dont have unlocked bootloader wrong chip.

So I was fortunate enough to get a warranty replacement that is BOC4 after being stuck with a phone that came in on BOE1. I already have it rooted stock NCG and am preparing to put Safestrap on it.
I am planning on installing the Optimal BOG5 rom on it and want to be sure I am doing this correctly as I MUST have the ability to roll back to stock if I have to return it under the extended warranty.
As I understand it: I flash the ROM. Then I flash flash the firmware. Then I flash the OD5 bootloader.
Questions: Since Optimal is a BOG5 ROM do I flash BOG5 firmware? Or do I need to find OD5 firmware since it is OD5 bootloader?
I am assuming I have to use OD5 bootloader so I can roll back to stock later if needed for warranty as BOE1 and OG5 are locked tight?
Any help would be greatly appreciated. I was rooted early on in S5 life before there was a 5.0 and am anxious to get back to it but REALLY don't want to bork the phone. This has to last until the S7 drops in January.
I currently have AT&T stock (I used to have a custom ROM then had to flash to stock ROM to be able to flash to another custom ROM--however, I accidentally flashed a newer version of the AT&T stock ROM which locked my bootloader and I could no longer flash to a custom ROM). I updated my AT&T stock ROM recently and now my back/menu buttons don't work, so I want to see if I can flash to a custom ROM now.
I don't remember the procedure to flash a custom ROM--do I first need to get root in order to unlock the bootloader to be able to flash ROMs (i.e. if I have root then I am guaranteed to be able to unlock bootloader in order to flash ROM)? Is the baseband version the only thing that determines whether I can unlock the bootloader and then be able to flash ROMs?
I currently have OK2 as broadband version and checked one of the stickied threads which said this:
" ROOT
OK2 -- No direct root method. Must Odin OC4 kernel, use Kingroot, then Odin OK2 kernel back."
Does that mean what I have to do is use Odin to get OC4 kernel, then use Kingroot, then Odin OK2 kernel and then I will be able to have root, which means I can then unlock my bootloader and be able to flash to ANY ROM (not just TouchWiz-based ROMs)? Is there anything else I need to consider or is this 100% foolproof? In the future, what should I be careful of in order to prevent getting my bootloader locked again--just that I don't flash a stock (AT&T) ROM that is known to lock back the bootloader?
Thank you all!
There's no way to unlock the bootloader if you have updated your device to the lastest firmware version. The only thing you can do is flash SafeStrap and use Stock Kernel Based ROMs which are compatible with Safestrap.
As regards to the procedure of rooting an OK2 firmware, I'm afraid I won't be able to help you.
Have a happy new year.

I was just about to sit down and flash a stock ROM. Can you explain what you mean by this? Did you flash OK2 and it caused you a problem?

It was a while ago but I used to have I believe an MDL broadband version which meant I could flash any ROM available. I tried a different ROM, didn't like it, then decided to flash back to the stock ROM but accidentally flashed a newer version of it, which meant that my bootloader is now locked. With a locked bootloader, apparently I can only flash to a newer stock ROM (not other ROMs like Cyanogenmod) via Safestrap.
I think if you don't have the MDL broadband version you shouldn't worry about it anyway because it is locked and you will only be limited to flashing stock ROMs.
Slight correction
The previous entry is not entirely correct. Like the OP, I was originally on an unlocked bootloader on my i337. I'd purchased my i337 on the first day and eschewed OTA updates. I wanted to try a touchwiz based ROM, Hyperdrive, and in doing so I recall flashing the stock NB1 firmware. Every firmware beginning with NB1 has a locked bootloader and there has been no progress for more than a year in unlocking the bootloader again. This can limit you to either stock ROMs OR other touchwiz based ROMs like Hyperdrive. I love the Hyperdrive ROM (now on release 21) but its developer has moved on to a newer phone, so it's stuck at Android 4.4.2 and no one has picked up the project in many months. There are several other touchwiz based ROMs for the i337 version of the S4 which I have also tried but I prefer Hyperdrive's myriad customization, even without proper patching. I'll be moving on soon to the Nexus 6P as my daily driver, but would very much like to keep my S4 up to date with a custom ROM. Given the number of people that have been in this same situation, where a newer stock ROM from AT&T locked a previously unlocked bootloader, it's been surprising that the issues have not been overcome on a phone as popular as the Galaxy S4 was and continues to be. I've seen unlocked versions of the S4 selling for just under $400 in the last week of 2015.
Use the desktop version of Kingoroot to root and use Super su and update the binary. Don't forget to hit thanks if this helped.
The bootloader for the at&t s4 was never unlocked. The MDL bootloader had a flaw in it that allowed you to use LOKI which is a lock bypass, not a way to unlock the bootloader.
I have another S5 I am running 4.4.2 on and would like to load the MOAR Rom to it. How can I do this and get around the Verizon warning about unapproved software? My phone is rooted and had Safestrap 3.75 right now. I tried to load the MOAR Rom via safestrap and got the unapproved software warning. Thanks! I am a noob with fighting these super locked down things from VZW.
I would lke to know the same thing
This is my recommendation as to i don't care to flash anything higher than OD5. You can flash Muniz_ri's to OC4 and keep root ROM and from there flash away to any ROM in this Forum section and update the firmware by flashing the latest firmware NO Bootloader Zips. Again that's what I do and haven't had any issues and i can Odin back to NCG and "officially" run a KK ROM. Also, I'm currently running the MOAR ROM and on the latest firmware which is PB1. Was running Jrkruse's Norma Note5 ROM but went back to MOAR for the moment....
Looked thru the other threads, and didnt see anything that pertained directly perhaps someone can point me in the right direction.
Have my stock S5 from verizon, on 4.4.4 NK2 firmware. Looking to update to whatever is the most current stock firmware with root. I'm coming to this from years of rooting Sprint devices, this is my first Verizon and I've been putting it off forever. Been getting the nag screen everyday now for a software update and I figured it was the time to update this and get myself root.
Thanks in advance for any help in where to look. Please forgive me in advance if this is a duplicate, I searched...I really did, but since its all new to me I wanted to ask.
Looks like the process is to flash 4.4.2, root, check if bootloader can be unlocked, and then proceed 2 different ways if it can be dev bootloader unlocked. If it can, unlock bootloader, flash twrp, and then flash whatever rom you want. If you can't unlock the bootloader, folow the guides to upgrade keeping root with safestrap and use roms that are TW for locked bootloaders. Someone correct me if I'm wrong. I just got a 4.4.4 g900v myself in a trade and I'm figuring out how to proceed as well.
Ok, slight difference. You can root & check the bootloader from 4.4.4...

I have a question since I watched the youtube video on how to upgrade my phone samsung s4 at&t to Oreo, but I read that I need a bootloader. Then when I read articles here in xda, mostly says that this phone can't be unlock? so How do I deal with this? Please explain simply because I am new in this.
If the phone is running an MDL bootloader, it may be possible to flash Oreo. If the phone is running a newer bootloader, the phone can only run TWRP and will not run Nougat or Oreo.

You cannot unlock the bootloader. However, if you're on the MDL bootloader then you can use an exploit called loki doki to install a custom recovery and a custom ROM. If you're on a newer bootloader other than MDL, then you are stuck with only booting custom touch wiz based ROMs and must use safe strap if on kit kat or flash fire if on lollipop.
Can you oden back to mdl if you are running NJ4.
does it matter id i upgraded to Kittkatt with a custon rom vs ota update on if the bootloader got locked? does goldeneye kittkatt 4.4.4 lock the bootloader?

No you cannot odin back to MDL, if you try you will brick your phone. It doesn't really matter how you update given your bootloader is locked (unless you're on the MDL firmware). Golden eye ROM does not lock the bootloader, no custom ROMS lock the bootloader.
