So the developer edition of note 3 is on samsungs webpage, but I dont see anyway to buy it without it being full price. Is there any major difference between the two? I know one has an unlocked bootloader, but 2 questions. Is there not some way to import the unlocked status to the non-developer edition? Just the same, are we now going to have 2 versions of ROMs, one for the developer edition, and one for the non-developer?

In a nutshell the dev edition has an unlocked bootloader which allows kernel's to be flashed, along with no worries of being locked down by a future vzw update. Current rom's work on both editions. You can only buy it from Samsung for full price as it does not receive any support or updates. You cannot add insurance to the dev edition and the warranty is only 30 days.

Dev Edition: unlocked bootloader, which allows you to flash kernels, roms, and basically do anything that you want to with you phone.
Non-Dev Edition: locked bootloader, can still root and flash roms, but the selection is very limited
I know the verizon dev-edition Note 3 can flash verizon and t-mobile roms

On the Dev Ed, the bootloader is unlocked as opposed to the factory unlocked retail version.
This makes it possible for the Dev Ed to flash AOSP roms such as CM11 or PAC-rom, and you can flash custom kernels.
Retail versions cannot flash anything other than modified stock based roms.

And factory unlocked just means the software is not white listed for just one carrier Sim card or set of frequencys.
dev edition is factory unlocked plus unlocked bootloader.
So I should get a note 4 dev ed if I want to root my phone right?

You can get root on a retail Note 3 as long as it is Android 4.4.2 build NC4 or earlier
Yeah but I'm already on 4.4.4 on a retail verizon note 3 & don't want another retail note 3
& I want to have the latest update installed
The S4 is still a decent phone in 2016 with it's amoled display, pretty good battery life, and decent performance. But it's a shame that AT&T/Samsung offer nothing for unlocking the bootloader. The last time that I searched, the only option for an SGH-I337 OK2 build was to install Safestrap and a Touchwiz rom. Has anything changed? I tend to use apps from FDroid, and I would really like to run a debloated rom such as Cyanogenmod on this thing (no Samsung/Touchwiz, AT&T, Google). What are the best options today?

None so far for the locked bootloader, unless you have 2013 bootloader like ADB, MDL.
AT&T intentionally lock the bootloader as such they will not offer any tools or ways to unlock the bootloader. Not just S4 all the AT&T phones has locked bootloader.
With the locked bootloader your option to flash custom rom is via either safestrap ro flashfire.
Regardless of what custom rom you use, you have to flash the AT&T kernel in the end, in order your phone to work.
There might be some AOSP roms flashable with safestrap in Android development section.

It sounds like it is time to either abandon ship on AT&T, Samsung, or both.
Any recommendations on carriers and devices in the U.S.?
I really like Samsung's amoled displays, and 5.5" is getting too big for portability / everyday use. My HTC One LCD display gives me eyestrain after much use. And it seems to be a problem finding a ~5" amoled device that is both AT&T compatible and allows for unlocking the bootloader.
Ideally, I would like a device that has ~5" amoled display, sd slot, good battery life, removable battery, and can run custom roms on a carrier who doesn't try to be a dictator on what I can run on my own devices.

I think all the samsung phones made for america has locked bootloader. You can check on this forum for which phone can be rooted and which are not.
The other way around should be using the international phones. However, on AT&T network, only the phone make for AT&T can get the LTE signal. I tried with the Asus Zenfone 2. The only way I can get LTE signal in Asus Zenfone 2 is on T-mobile network.
I like the idea of removable battery but in order to make the phone thinner, they all have to go with the I-phone route, non-removable battery.

There is a new Android AOSP 7.0 Nougat ROM for Galaxy S4 AT&T, but I don't think I would be able to install it because my bootloader is UCUGOK2?

Yes they clearly stated that your bootloader has to be exploitable (MDB/MDL). If not that bootloader you can not install custom recovery. Those rom need custom recovery to install on the phone.

Thanks Sway.
Is it possible to unlock bootloader UCUGOK2 and change it to UCUAMDB or UCUAMDL?
If so, do you have a link guide?
Thanks again.
There is no way to flash an unlocked bootloader over a locked bootloader or to unlock a locked bootloader at this time.

For the ATT-S4 , the answer is no. There is a JTAG service to unbrick the bricked bootloader but there is no posting saying that re-write the bootloader to MDB/MDL.
So far, only the verizon S4 has a way to unlock the bootloader.

Not possible to run anything other than tw. There are great tw Roms that are debloated making them very light and fast especially when paired up with a custom kernel and the correct settings. Just a got an old s4 from a friend and I decided to revive it from its misery. Now it's snappy and decent battery life.

Not all Samsung phones have locked bootloaders in the U.S. Just Verizon and AT&T, unless t-mobile and sprint jumped on the locked bootloader band wagon.
how do you verify if the BL is Locked? Because I managed to root and change modem to mdb and rom to mk2 from much higher version, sim unlocked my att i337, so i just want to check before I load a new rooted rom, from safstrap
Boot into download and confirm that the model # is sgh-i337. Do you see anything about Knox?
You could also boot into the ROM, install the Samsung Info App, and look at the bootloader version.

I'm in the same unfortunate boat as OP. I downgraded from 5.0.1 / OK2 to 4.4.2 / NB1 and rooted in hopes of installing custom ROMs but now I run into what looks like locked bootloader. When in download mode my details are:
KNOX KERNEL LOCK: 0x0
KNOX WARRANTY VOID: 0x1
what can i get out of this info?
The bootloader is definitely locked and cannot be onlocked. You can use safestrap to flash custom ROMs that are based off a stock TW ROM. You can also root the phone and debloat.
I was really salty about the bootloader being locked when I upgraded from my S3 which I had CM13 rom. Last few months I've been using Thor rom, absolutely solid and I got the Grace UX look on it. I'd recommend it or Lollirom.

Maybe this other thread can point you in the right direction. I tried the Xposed framework portion however, but that part wouldn't work with my AT&T Galaxy S4.
Thread: [GUIDE] AT&T Samsung Galaxy S4 SGH-I337 Lollipop 5.0.1 OK2 Root Xposed Etc.
Keeping my eyes open for other options. Good luck.:good:
Here's the round up as far as AT&T Samsung flagship locked bootloader phones go:
Galaxy S - factory unlocked bootloader
Galaxy S2 - factory unlocked bootloader
Galaxy S3 - factory unlocked bootloader
Galaxy S4 - factory locked bootloader - exploit bypass (loki doki) available if on MDB or MDL firmware.
Galaxy S5 - factory locked bootloader
Galaxy S6 and variants (S6 edge) - factory locked bootloader
Galaxy S7, S7+, and S7 edge - factory locked bootloader
Galaxy S8 and S8+ - factory locked bootloader
The only AT&T phones I know of that can be unlocked bootloader wise are HTC devices as HTC offers a developer program which will unlock it for you. I am not sure about LG, Google, or Motorola devices branded by AT&T.
I have a note 3 with stock lollipop rom model n900w8 which is the canadian note 3 version. I just want to know if it will be sim locked again if I installed a custom rom like magma or darklord?
PS. I don't know if it was sim locked before, I just got it sim unlocked already.
Additional question: can I just go back to stock kitkat from stock lollipop without rooting?
How was it sim unlocked? With an unlock code, the phone should be permanently unlocked regardless of flashing a custom ROM or upgrading bootloaders and modems.

Most likely it will never re-lock itself
Every phone that I got from a carrier and subsequently unlocked via code, including the n900w8, or a free method (i.e. Samsung note 2, s3, s4) has never relocked after flashing a stock or custom ROM.
I was looking into buying a J727V, it looks like the bootloader may be locked, obviously this stops me from putting in my own custom rom, can anyone confirm?
Last time I bought a (I think) Note 4 I had to get a developer version so that the boot loader was not locked in order to put on a custom rom.
If it is bootloader locked is there a different version of the J7 that I can get that I can use on Verizon?
