Hi, I was wondering kind of the same thing as OP but with different G900 models. In my case, I would like to flash G900W firmware on the G900A. I assume this isn't possible?

You assume correctly
Bootloaders are different, blocking the install even if the hardware is identical
Other things like modems possibly too
There are 'custom' stock ROMs such as the G900T that are modded to be flashable on G900F etc, but you can not flash 100% untouched stock from one model to another

Would the installation of custom stock ROMs require root to flash? I believe the G900A that I have currently does not have a root for its 5.1.1 firmware.

[Q] Flashing i9505 ROM + Modem on SGH-i337?

Hi folks, I'm thinking about getting the SGH-I337 (AT&T version of the s4) which from what I've heard is identical to the i9505 but flashed with a different Modem and ROM. What I was wondering was if it was possible to flash the i9505 ROM + Modem onto the SGH-I337 and essentially "convert" it to the i9505. I was wondering if anyone had more details on the hardware and if there were any issues that I'm just not seeing. I see that the ROM is not an issue. More curious about the Modem. I would like to use the phone on LTE in the UK
I'm looking for a 32GB version of the i9505 and so far, the only option I have is the SGH-I337.
Any thoughts?

Yes you can flash i9505 rom but not sure if you can flash i9505 modem. The way everybody is doing it, to insure ATT network compatibility, is to flash just the i9505 rom while keeping the ATT radio. By doing so, your device ID will switch to GT-I9505 and the SGH-I337 will be gone.
So from what I'm understanding he can flash the i9505 ROM which by he means stock firmware? So I can flash i9505 5.0.1 lollipop stock firmware on my i337? That's what I understood. Is it true?
The bootloader on the i337 may be locked so flashing the i9505 stock firmware onto the i337 may not be possible. I am just guessing here as I have the i337m which does not have a locked bootloader.

Mine is not locked, I bought it used and it was rooted already, so I installed twrp through flashify and I am using cm12. The reason I'm asking is because in sammobile there isn't any lollipop not even kitkat firmwares for my i337 model. So I wanted to know if flashing the i9505 kitkat/lollipop stock firmware on my device could be fine. If not, I can keep on using cm12.
Att never released a complete kk or LP rom. These were only available via ota updates which explains why they cannot be found on sammobile.com.

How could I update it then? I'll be stock in jellybean 4.2.2 because with no root I never received the ota update nor for kikat and not even lollipop.
The rom must be running a completely stock 4.2.2 rom, including stock recovery with no root, to install ota updates.
You could look in the general or development forum to see if anyone has made a flashable zip for the ota updates. The again, the ota updates may not work without an updated bootloader and modem which may mean locking the bootloader.

Samsung Galaxy S4 I337 cannot find latest update 4.4.4

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.

OK2, Android 5.0.1--what are my options?

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.

[Help] Install twrp in Galaxy s5 sm-g900v 6.0.1

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..

I just got the s5, but i get rid of it,im back on my old lg g2, seems it was imposible to install a clean rom on that device.
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.

I've searched but I'm lost on where and how to downgrade 6.01? Is it just flashing over a 5.0 ? or is there more to it because it's new? And where can you find a guide for rooting 6.01 or downgrading it and then rooting?

I already gave the phone to my gf, but what would happen if I try to flash a stock based debloated rom with my pc? I mean flashing the debloated version of 6.0.1?

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.

you can downgrade from marshmellow to lolipop however you cannot downgrade to kitkat due to the fact that the bootloader is different
I advise you DO NOT make move to unlock bootloader on locked device.Like install 900f roms 900f kernels. Because i tried this **** and my s5 is turned to trash. Do not try belive me.

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!

European ROM on SM-G900A

Is it possible to flash an EU ROM on the US version of the phone? I have a SM-G900A, but it does not have EU languages.

Any difficulties that will occur doing this? Or can I just download the stock SM-G900F ROM and flash it safely?

Difficulties? Joking? It's rather a tricky process as G900A has a locked bootloader and you want a ROM from another model.
You definitely cannot just flash "F" firmware with Odin.
Schematically, this process looks like:
1. Go to G900A section and find COMBINATION ROM there.
2. Find the latest G900A stock ROM and make a firmware Odin-flashable tar from it (bootloader, kernel, modem, recovery).
3. Find a G900F ROM you want to be on, prepare it for flashing if needed.
4. Flash Combination ROM, gain root, install Safestrap recovery.
5. Flash G900F ROM from Safestrap recovery.
6. Flash G900A firmware package with Odin.
7. Enjoy.
