Can I install CWM on the GS4?

Hello, I've been out of the rooting scene for over a year now since I bought my Galaxy S4. When I first bought it, i had it rooted but could not install a custom rom because it was on MF3. So, once again I am trying to get back into rooting with the latest OTA update and a NC1 baseband. I've been looking around on how to root and install a custom rom but I've been gone so long that I'm just lost.
From threads I have read I can downgrade my phone to NB1 then to MK2 to root. However, I haven't really been able to find an answer to if I can install a custom rom to it, only upgrading back to the OTA and keeping root. I have been having massive overheating problems with the stock firmware and have a large burn mark on the back of my phone and would like to switch back to CWM which i had on an old phone.

No CWM. You can only use Safestrap, a variant of TWRP for locked bootloaders that doesn't flash kernels. Due to that restriction (if we tried to flash a custom kernel we'd get bootloader check fails) we can only run ROMs which the stock kernel supports, meaning other Touchwiz ROMs and the one GPE that's been posted in the General section. Part of the downgrade and root process is using Safestrap to update to 4.4.2 with a modified OTA, and so you just replace that step with flashing a ROM, the kernel modules, and then the ODIN files.

[Q] help me understand the root world a little more

I'm trying to learn more about the S5 root world. I am currently running the OTA NHA build, and am rooted using towelroot, and have the latest safestrap installed (also have supersu and busybox). What i am trying to understand is how the custom rom's work now. I just got the S4, and never had my bootloader locked since i rooted/rom'd earlier on and never ran stock, and i was using TWRP so there were no rom slots or the like; you downloaded a rom, wiped your phone, flashed it, done.
This bootloader/kernel/baseband talk is what's confusing me. A question that i've been trying to find the answer for is as such: let's say i have my NHA rooted phone, but there is an NE9 rom on the forum i want to try (extreme syndicate/alliance). Can i just flash that to a rom slot and go, or do i flash the kernel as well? if i flash the kernel, won't that mess with my stock rom, or does that just patch the kernel inside of the rom slot?
I already understand that chronologically, the baseband/build versions are NCG>NE9>NHA>NI2, so understand that rom's baseband is a version behind NHA. Someone please help clarify some of this for me

Is there root for Samsung Galaxy S5 SM-G900T3?

I bought a new Samsung Galaxy S5 today at a local T-Mobile store. But it turns out that the model number is SM-G900T3, for which I cannot find any information on how to root and install custom recovery. Has anyone had any luck with this model? It's build LMY47X.G900T3UVU1FOF6 Android version 5.1.1
Thanks!

What to do for G900T3 S5
Same here. I went from S4 running cyangenmod 12.1 to s5 g900t3. All because i cracked the screen on my s4. I don't like the stock firmware too much on the s5 so I've been researching rooting it. But run into the same issue. No info on rooting this model. The only thing I can think of to do is downgrade to 4.2 using Odin then root and install CWM. Yet I found a forum where someone posted they were unsuccessful in downgrading the g900t3. So HELP PLEASE.

Turns out it's actually simpler than that. If your goal is to replace the stock firmware with a custom one, such as cyanogenmod then you don't even need to root your stock firmware. All you need to do is flash TWRP custom recovery with Odin, then reboot into TWRP recovery and create a backup of your stock firmware just in case. After that you should be good to go ahead and install cyanogenmod or any other supported custom firmware. This is exactly what I've done with my SM-G900T3.
But if you really want to root your stock firmware then here is a guide for that:

Hope this helps.

OK thanks for the link. It does state not to flash if I'm on FOG6 Build, which I am. Even though my baseband version is FOF6. Guessing the Build is more important. Last night I tried to downgrade to 4.4 using Odin, that immediately didn't work. So I Flashed Philztouch CWM on it then tried to install superuser from the galaxys5 root page, but it was stuck in bootloop on the T-mobile screen. I realized the superuser was for 5.0 version. So then I used Odin again to flash my firmware back on to it the g900t3 5.1.1 FOG6 from the Sammobile website. After that, because I saw I had a reply on here, I used Philztouch to install Cyanogenmod 12.1 nightly recovery (don't know which on it was, either klte or klteusc) without rooting and I was stuck in the Cyan's big eyed alien face thing bootloop screen again. So then I had to reinstall my stock firmware once more. Basically after 4+ hours of rooting I'm back where I started. LOL. I don't know what else to do. I'm still researching FOG6 to see if I find anything.

Would this be the same procedure to follow if I wanted to put a stock T-Mobile version of 4.4.2 on my SM-G900T3? Or would that not work?

[Q] [910U] How updatede to MM with Root

Dear Friends,
I am owner of 910U device on L , rooted and with TWRP.
To update MM, I was going to flash Offical firmware of MM 6.0.1 , to have latest modem bootloader.
But we do not have root or CF auto root, for MM yet. So I cannot root and re flash TWRP (as I think)
However, I have seen some people on forum that have MM on 910U device, with root.
So I was wondering, Is it possible to keep root and twrp while flashing orginal firmware?

As far as I know, there is not root method for marshmallow yet. I flashed the original firmware which reverted root.

I'm on MM, but 910H model. I took a chance and flashed 5.1.1 cf auto root from chainfire, for the 910H and it worked. Just rooted, no custom rom. No problem whatsoever. Smooth as butter.

Thank you all. I did. thanks to @djmax
1- I Flashed, modem and sboot of 6.0.1, over L firmware. System was working.
2- I flashed erobot firmware of 6.0.1
3- flashed SUSE MAX kernel of djmax work for 910U
4- rebooted, : had no signal, no superuser, noise crash for calls..
5-Flashed modem, sboot again for 910U
6-flashed super sU zip 2.71 from chainfire
7- flashed noise fix for 910 U
8- flashed SMSfix from erobot..
ALL working now.

Updating to Marshmallow on OF1

Been off this thread for awhile (you know how life gets in the way) and was wondering if there are any meaningful upgrades to an S4 with 1545VRUGOF1 rooted via Flashfire. with stock.
C

If you want marshmallow, then custom ROMs are the only way to get it.

Which s4 do you have? Isn't flash fire for the i337?

At the time, Flashfire was the only path to root

Look here for a possible answer: http://forum.xda-developers.com/galaxy-s4-verizon

Any guidance? I have the VRUGOF1 Bootloader and consequently was only able to root with Flashfire. Not sure if there has been any development to allow Marshmallow to be put on this device

Yes, there are ROMs for that device. But you can only flash with a custom recovery so you'll have to find one.

Look in the Verizon forum. This forum is for the international version of the s4.

Maybe I'm not being clear, but I was uder the impression if you have the OF1 Build you can only root with Flashfire, and, you cannot install CWM or TWRP as it will brick your device. I am not looking to add another ROM, I am fine with stock. My goal is to see if there is a way to go from Lollipop to Marshmallow safely given my specific device parameters

If you can't install any custom recovery, then there isn't any way you can.
There is no official TouchWiz Marshmallow ROM for the S4, as such, the only way to get marshmallow is through a custom ROM.
A custom ROM can only be flashed via custom recovery.
Ergo, if you can't flash a custom recovery, there is no way to get marshmallow.

The Verizon OF1 bootloader is locked and not exploitable. Only the MDK bootloader had that luxury. You also cannot downgrade to it. If you want to flash a ROM other that stock head to the Verizon Galaxy S4 development forum and read up on SafeStrap and ROMs that can be installed with it. A custom recovery such as TWRP is not able to be installed on your device. Because of that ROMs such as CM, JDC custom ROMs, etc. are out of reach for you.

Thanks
So to summarize, since I am on the OF1 build and could only root via Flashfire, the bootloader remains locked...consequently I still cannot flash TWRP or CWM, and as you put it, out of luck to get Marshmallow.
However, has anyone successfully used Flashfire and Xposed? I saw it on another thread: https://www.reddit.com/r/AndroidQuestions/comments/406o9w/verizon_galaxy_s4_unlocked_bootlaoder/
but there was no definitive conclusion that it was successful. Anyone have any direct experience with this? Since Safestrap and Flashfire are both custom recoveries installed alongside of your locked bootloader, do either work to get to Marshmallow?

You are a little confused. SafeStrap is not a custom recovery so to speak, TWRP is. SafeStrap allows the installation of some mods, etc. on devices with a locked BL. A quick look in the Verizon S4 Android Development forum does not show a MM build that can be installed via SS, only LP builds.
The issue with a locked BL and SS is you cannot install a different kernel which limited what could be installed.

I saw a set of OF1 instructions out on Stang5litre's OP for his ROM. Has this been validated as a stable rom for those of us on OF1?
