Hey guys,
My brother has the S4 i337 model and he's on 4.4.2
This phone is unlocked and he's using Tmobile on it.
For some reason it cannot find 4.4.4 via OTA and Kies
Is this because it's on tmobile or this model didn't get 4.4.4 yet.
Do I need to root it and flash a rom on it?
Thanks

Some models of the Samsung Galaxy S4 just didn't get the update, for instance my i337 didn't even get the 4.4.2 Kitkat update and was stuck on JellyBean. Your best bet is to just flash a 4.4.4 Rom on it. Clears out the bloated stock software.

that's really lame
So to make sure I do this the right way
I have to root the phone first
then install custom recovery
then flash rom right?
Or does the boot loader need to be unlocked?
Any rom recommendations?
I'd like for it to be stock so it's stable since my brother needs this for testing purposes

Yes correct, but if your boot loader is locked then you're going to need to download SafeStrap Recovery for locked bootloaders. Then once you have installed that, there's only very limited amount of Roms you can install because of the kernel, if you find a ROM that changes the kernel your phone won't boot. But a ROM that is fully working is called "GoldenEye ROM" its a 4.4.2 ROM but is really clean, stock, and clears out all that bloated nonsense. There's no 4.4.4 Roms for locked bootloaders yet.

Hi, I'd like something cleared up. I have a Verizon Galaxy S5 running Kitkat 4.4.4 which I have rooted. I was wanting to flash this Liquidsmooth ROM on it. It says it supports it, right? But how do you install this ROM if the locked bootloader keeps you from installing TWRP or CWM Recovery? Can it only be installed on the developer edition? I can't seem to find a definitive answer.
Thanks in advance.

It says in the OP the ROM is AOSP based, which means you cannot flash it on the retail Verizon version. It can only be flashed on the Developer Edition Verizon variant.
Ok, that's what I was thinking, but wasn't sure. Thanks for your help!

I was wondering exactly the same thing. I'm a total noob, I've never flashed a ROM. I rooted Verizon Galaxy S5, w KitKat 4.4.4. I wondered: if Lollipop kills Safestrap, how am I supposed to recover from a inappropriate Lollipop ROM? I was so frustrated by this question, I just bought (a cheap, mint) Developer Edition Samsung Galaxy S5. Now what? I would like to flash ROMS on my new phone , have found threads to do so, but the general question remains: what ROMS are right? Can the Developer Edition (DE) take any ROM that a non-Developer Edition can take? Can the DE S5 take ANY AOSP ROM? Such as CM 12.1? And to phrase the question for those with the non-DE S5 - how does one recover from a bad Lollipop ROM, if one cannot install recovery on a locked bootloader Verizon S5? -- and if one cannot use Safestrap (because I thought Safestrap was broken in Lollipop). Does one have to downgrade to KitKat to fix an incorrect ROM situation? Lots of questions, I'll research, but these still remain. Thank you!

A developer edition cannot run Roms for the retail edition. You will lock your device. You can backup your phone or flash something else by using Odin to flash a kernel of an earlier build such as nk2. This will bring safestrap back up.

I wouldn't suggest installing roms based off retail firmware for the de version as it'll probably lock your bootloader. Developer editions can take any aosp rom made for the kltevzw, and any rom that isn't based off of retail firmware, for that matter. Safestrap doesn't work on lollipop, but if you want it to run all you have to do is flash a kitkat kernel on odin and safestrap will work again, ths system will not, however, unless you install a lollipop kernel.

Are there any AOSP ROMS based on CM12.1 that are semi-stable? I saw the one by albinoman887 , but that one does not yet seem stable, and since I am a n00b, might not be a good idea to flash it.... Are there any other ROMS for Samsung GS5 kltevzw phones with unlocked bootloaders that you know of?

I am too unfamiliar with the developer edition. I wouldn't want to mess up your phone.
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.

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.
Hey there I just got a new samsung galaxy s5, and I have been searching on the internet since yesterday, and haven't been able to find a thread that gives me information about installing custom recovery or installing a rom based in stock without any bloatware.
My phone is the samsung galaxy s5 sm-g900v (not rooted, i haven't been able to do it, maybe it's not posible yet )
android 6.0.1
kernel version 3.4.0
So my questions are:
Can I flash the twrp.tar file with odin?
Is there anyway to install a rom based in the stock of samsung but without bloatware?
And finally, can I root android 6.0.1 in my verizon s5?
Thanks in advance
you have alot to learn my friend.. if you are on 6.0.1 i dont think you can downgrade. you need to be on a 5.0 and then root then if you have a samsung board you can unlock the boot loader to install TWRP if its a toshiba you cant..

6.0.1 is downgradable. If you had a 15 chip then you could get TWRP. Even if you had an 11 chip you could still flash a debloated rom on Lolipop.

Flash a G900V 5.0 Lollipop Odin TAR. If you have a CID 11 chip then you can either:
- Downgrade to lollipop and stay rooted their.
- Stay / upgrade to marshmallow but not have root.

Why are you advising those with a locked bootloader not to unlock it? If you have the right emmc, there are like 4 different methods to do it. It's simple!
Hello
My LG V10 came across the famous bootloop issue, and I shipped it to LG. In the meantime, I am using an old S4 that was saved for emergencies like this one. It is running 4.4.4, I337UCUFNJ4, and I rooted it with Kingoroot.
I understand that it should OTA to 5.1 in pronably a day or 2 if I check for a software update; it sat turned off since 2014, so it did not receive anything.
1. Do I OTA and reroot?
2. Can I manually jump to 5.1?
Ultimately, I would like to install TWRP and the Blissrom or some other ROM, but I don't want to take an OTA that may screw me up for later. I read that there's a loki thing that will prevent future installations of recovery or something like that. I realize that I will be using a short time (2-3 weeks), but I would like to leave it rooted and with a good ROM.
Thank you
The bootloader is locked so that means TWRP cannot be flashed to the phone and the phone will only run custom ROMs based off a stock Samsung ROM.
OTA updates will not work if the phone is rooted.

I'm confused or perhaps you are misinformed. I have seen a lot of ROMs for this device including Blissrom and many others. All od them get flashed through twrp or Safeway or aome name like that.
You mean safestrap?
Maybe you are thinking of the non-AT&T models of the s4 that work with custom ROMs such as Lineage and Validus. Only the AT&T version of the s4 has a locked bootloader, starting with Android 4.3 and up.
There has never been an sgh-i337 s4 with a locked bootloader than can run TWRP. Same goes for the AT&T sm-n900a note 3 with a locked bootloader.

But there's a forum dedicated to AT&T development full of roms here on xda.
Yes, there is a full section but you need to look at the ROM requirements. Some of these ROMs were developed before AT&T pushed out an OTA update that locked the bootloader. Other ROMs are made for the non-AT&T s4 such as the sgh-i337m and gt-i9505.
You will not see any ROM that is not based off a stock Samsung ROM that can be installed onto an AT&T s4 that has a locked bootloader. Also, you will not see any version of TWRP/CWM/Philz that can be installed onto an AT&T s4 that has a locked bootloader. Same goes for the AT&T sm-n900a.
I understand your skepticism and appreciate your posts as we are all here to learn from each other.

Thanks for the clarification. So how do I know if my bootloader is locked? If I took that ota update that messed things up?
The bootloader becomes locked when the phone is updated to Android 4.3 or newer. I think it needs to be on the MDL bootloader to be unlocked. Anything beginning with an "N" or "O" means that the bootloader is locked.
Thanks audit. And I assume that there's no way to go backwards to a pre-4.3 rom and unlock that bootloader.
So. I'm on 4.44 rooted. Do i remove root and take any ota and reroot? I guess that I'll settle for going as high as possible with the stock rom but rooted with the ability to disable some of the bloatware.
How can I proceed?
In those links that you mentioned, it states that we can flash debloated TouchWiz roms that might be better than stock. Is that right? So can I do that?
You will need to install safestrap to flash a custom ROM. The debloated ROMs must be based off a ROM that is designed for the AT&T s4.
I recommend reading through this thread: https://forum.xda-developers.com/showthread.php?t=2616221
Audit... I odined back to nb1, rooted, and used flashify to get to rooted stock oc3.
How can I get to ok3? And should I leave ota services frozen so as to not ruin and loose root?
OTA will not work with a rooted phone.

I don't have an sgh-i337 so I can't tell you how to get back to a completely stock ROM to get OTA updates. I have the sgh-i337m which is the Canadian version of the s4 without a locked bootloader.
I wrote a guide and FAQ revolving around the MDL bootloader here (if anyone cares to read it):
https://forum.xda-developers.com/galaxy-s4-att/general/how-to-one-guide-to-mdl-bootloader-t3584122
Here are my phone specs
Samsung Galaxy S4 AT&T Android Version 4.4.4,
Baseband ver. i337UCUFNJ4,
Build # KTU84p.i337UCUFNJ4
So far, I have successfully rooted my S4 device using this guide
Link: https://forum.xda-developers.com/ga...to-root-i337ucufnj4-4-4-4-11-13-2014-t2939553
So far, this guide worked out well. I wanted to install Lineage OS and TWRP. I downloaded the TWRP app and flashed to recovery. Everytime I reboot my phone, there is a samsung logo and underneath the logo is a unlocked padlock. When I boot the device in recovery mode (Home + Volume up + Power button), I am prompted an error saying "System software not authorized by ATT has been found on your phone". The phone boots perfectly normal if I don't go in recovery mode.
Need help on flashing my phone back to normal to its factory stock to retry this again.
The phone has a locked bootloader. It cannot run twrp and cannot run a custom ROM unless that ROM is based on a custom ROM.

Can I downgrade the software from Android 4.4.4 to 4.4.2?
I'm not sure if you can downgrade from 4.4.4 to 4.4.2 as I've never had an sgh-i337.
Was in a similar situation as you, so what I did was use safestrap to run Thor Rom, you can't downgrade to fix the bootloader nor install roms apart from those Touchwiz ones. Heads up about the Thor rom one: clear the data from the download manager before trying to download stuff from the play store. If you got any other issues with the rom feel free to ask (My S4 broke a while back though)

It should be, 4.4.2 is the lowest you can downgrade to. I'm not sure exactly but it might be done through Odin
