[Q] Rogers GS4 4.4.2 NE1 Custom Recovery?

Hello, I have a Rogers Canada SGH-I337M rooted running 4.4.2 I337MVLUFNE1 and I would like to try custom roms on my phone but I have never tried doing this before and I don't know what custom recovery I can use with this baseband version. I was going to try Safestrap but the versions for it that I saw on its XDA page were for NB1, MK2, and MF3 baseband versions. Will the latest version of Safestrap be compatible with my phone, or will I need to downgrade/upgrade my android version to get a different baseband version? If I will need to do so, would I need to unroot or make changes before changing the android version? Help would be greatly appreciated.

Safestrap is primarily for the phones with a locked bootloader because we are not able to flash any other type of recovery. Since your bootloader is not locked, you should use philz touch or TWRP. That way you'll be able to flash kernels, as well.
Best advice I can give you is to read before flashing anything that way you know what you are getting yourself into. Since you are i337M, I would start with this thread... http://forum.xda-developers.com/showthread.php?t=2314494

Okay, thank you very much for clarifying that my phone's bootloader was not actually locked, I just assumed it was because I couldn't find anyone else with that baseband version. I have also read the thread you linked, I am going to try TWRP.

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:
http://forum.xda-developers.com/tmo...t/root-kernel-root-method-fof6-5-1-1-t3158005
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?

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?

SCH-1545
Android 5.0.1

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?

Rooting / TWRP

Heyyo, Slenderman8090 here! I am currently on the newest firmware build that Verizon Sent out. I am downgrading so I can flash/root OB6 Firmware. TWRP doesn't seem to want to flash via ODIN, but I keep getting an AUTH error on ODIN. I am a 3 Year patron of XDA/General Development, and I am not familiar with Verizon and it's lockdowns. So, what ever I can do, please let me know.
Thanks so much,
Slenderman8090
EDIT:
I HAVE FIGURED OUT HOW TO FIX IT, NOW AROMA DOESN'T WORK ON MY TWRP, WHAT VERSION IS NEEDED?

As far as everything I've been able to keep up with and read, in order for our Verizon (hltevzw) Galaxy Note 3 phones to be bootloader unlocked with a properly functioning TWRP recovery that also handles AROMA files as well, TWRP v2.8.7.0 (4.4 (the Verizon "hltevzw" variant), is the correct/proper variant that you'll need to flash onto your phone instead of the version that you've got currently. Also, it apparently doesn't matter at all whether or not you've already got a newer version of TWRP recovery installed, any newer version after v2.8.7.0 can't flash AROMA. So since you want to flash AROMA files, TWRP v2.8.7.0 (4.4) is apparently the last official version to be released which supports AROMA. I'm not sure why it didn't carry on into newer releases, but I'm sure the devs had a good enough reason for not doing so.

System software not authorized by ATT has been found on your phone

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.

If the bootloader is locked, how was I able to root the device?

Rooting affects the ROM, not the bootloader.
There are several phones with a locked bootloader that can be rooted.

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)

Hi
I want to downgrade my Android 4.4.4 to Android 4.4.2 because there are more ROM options for 4.4.2 touchwiz. Is this possible on the att s4?

On step #4, how do you install the ATT Kernel Modules?

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
