Roms for G935t? - T-Mobile Samsung Galaxy S7 Edge Questions & Answer

I see a lot of roms and root threads in the general galaxy s7e discussion forums but i see only 1 rom listed under the t-mobile variant. Are the other roms not going to work on G935t? or will they work but theres no point having multiple threads?
im coming from almost entirely nexus stuff before so this phone is still rather new to me with how locked down it is.

Tekv2 and Echoe are the only ones.
Personally and suggestion, i'll head up for TEKV2

This phone is locked down like Fort Knox. The locked bootloader was a big disappointment for ROM and root lovers, especially for early adopters like me.

I thought we had gotten past that? Or is it just that we have root but the bootloader itself is still locked?

Nothing has changed. We have root because of an engineering kernel that allows root commands. But bootloader will not allow us to flash anything that isn't developed or approved by Samsung.

Current state of AT&T bootloader?

My partner is looking at getting a new phone, and we are looking around at different models. We want one that we will be able to upgrade and flash custom ROMs on for obvious reasons. For the AT&T model, what's the status of the bootloader? I have read that someone had an unlock method a few months ago, but I've also read that new models have an update that breaks that method. Also I have read that there is a safestrap method to install custom ROMs without having to unlock the bootloader.
Can someone summarize the status of the above for me? We would be buying a new one from AT&T. Would we be able to unlock the bootloader, or use safestrap?
Thanks!

The best place to find the information you want is in the threads you said you read. There is nothing else to tell more than what is already in those threads.

Most of them haven't been updated in a month or more, or are dozens of pages deep. If you aren't going to be helpful then just don't comment. I frequent boards for other phones and try to help people with questions instead of condescendingly telling them to go trek through the labyrinth that is the world of Android development.

OK, continue being rude and lazy. I'll leave you to it.
Here's some help, your partner is probably going to get mk2 firmware. It's bootloader locked and probably always will be. You can use the right version of safe strap and flash a few roms.

Dev-Edition & Roms

Hey all been out of the loop for a little bit and I have a question. With the phone being as locked down as it is I was thinking of getting the Verizon GS5 Dev-Edition. Can I use ROMs and/or Kernels that are in the main GS5 forum?
Thanks for the advice/help in advanced!

If it's the Dev Edition and once rooted, I would think so. I could be wrong.

Appreciate the quick reply! I'd imagine Kernals might be hit or miss but ROMs would be ok but I could be wrong on both accounts and I just wanted to make sure before I bought it.

Either way, the Dev edition is the way to go. There is a custom build in 'Original Android Dev' for the VZW S5 down a couple subforums that is confirmed stable.

Yea I saw the Kernel but there aren't any ROM's in the Verizon forum, the main GS5 forum is hoping though so I wanted to make sure I can actually do what I intend with the device given the money. Especially since I know the Dev-Edition will never get official updates from samsung.

I'm curious myself. I just purchased an M8 but if we can flash ROMs from T-Mobile/AT&T/Int'l/Etc onto the rooted/unlocked S5 DE I'd probably buy that instead.

From what I'm reading it should be ok as long as we use a Verizon kernel because the Intl version seems to also have the Snapdragon 801.
Waiting for someone with experience to confirm though.

[Q] How to unlock a bootloader if possible? (N900A)

Heya, I'm very new in the vast world of Android rooting and flashing and I've run into yet another problem trying to flash my N900A Note 3 variant. I finally got it SIM unlocked and rooted and just when I'm getting ready to flash I see something about bootloaders. I don't know how to check to see if it's locked but I'm more than certain it is. So, is there anyway to unlock the bootloader? I see people saying it can't be unlocked yet I see guides for unlocking them so really all I'm looking for is a straight answer.
And if I understand it right, Safestrap isn't something I want to do if it's not the 'real' thing, so if it can't be unlocked then I'll be looking into another phone. If I do, would it be better to get another Note 3 variant or the Sony Xperia z1s?
Thanks in advance.

AT&T models are locked at the bootloader, and there's no way to unlock them.
I have similar question....I have 9005 version and want to put new bootloader.....I put new NF2 modem and now i want to put NF4 bootloader....
Is it enough just to instal it through odin?
(Searched for instructions but couldn't find it.....)
Thanks....

Okay, I have a few questions on this subject.
Safestrap is a work-around a locked bootloader right? If I use it to flash a rom would there be that much of a difference?
If using safestrap pretty much the same thing then why do people still prefer to have unlocked bootloader?
Because I see guides to unlocking bootloaders, does this mean that it's just AT&T that won't let us unlock this phone version?
Sorry for the questions, I just want this stuff cleared up.

You can't change the kernel if your bootloader is locked, so safestrap only works with TW-based ROMs -- no cyanogenmod our other AOSP variants.
AT&T is one of the carriers that forces the OEMs to lock the bootloader. I believe Verizon is another one. No other carrier seems to care, or have enough power over the OEMs to force this.

[Extremely Confused] Rooting the T-Mobile Galaxy S5 and flashing Cyanogenmod 12.1

Hi I recently got a T-Mobile Galaxy S5 and I despise Touchwiz. It looks ugly and more importantly it makes my phone extremely sluggish (it feels like my Moto G when it would run out of RAM). I want to root and put a ROM that's as near stock as possible (I'm assuming CM12.1 is the best option for that) but I haven't rooted since the Galaxy S2 so all the information I'm reading is super overwhelming. All these stickied posts seem rather outdated coming from like 2014 and such. I'm on 5.1.1 and I honestly just want as lagfree of an experience as possible. Can someone here please help me acheive this? I've been researching for 2 weeks now and I'm horribly confused. I keep reading about custom kernels and all that but all I want is my phone to not suck.
You'll get more answers in the correct forum

Have you tried a different Launcher first though? TouchWiz Launcher is terrible, Nova Launcher is what a lot of people use, myself too, super fast, smooth with 100x more customisation options

I'm not rooted. I'm confused because when I try to figure out how to root and flash my phone all I see is a bunch of different guides and I'm not sure which is the one I should do.
Not sure if the T-Mobile bootloader is locked, I know the Verizon one is, and another US carrier, if it is locked, it's a PITA
If it's not, flash CF Auto Root for the G900F with ODIN

T-Mobile S5 doesn't come with a locked bootloader which is good. I have the G900T would that work?

How do I flash something with Odin? And will this work on 5.1.1?
Best do some reading before messing if you don't know how to use ODIN
And no, I don't believe it works with 5.1.1, there is a thread about rooting 5.1.1

Was the same for me when I got mine, I spent 2-3 weeks reading every single thread I could before I decided I knew enough to root and be confident I wasn't going to brick it
And that was after I was already well experienced with Android, just a different device
Don't try taking shortcuts is my advice, asking for help and guides is one thing, but reading absolutely everything you can first is the only sure way to not kill your phone

DISCUSSION THREAD: Root for Snapdragon USA Variants of S8 and S8+ (G950U/G955U)

User "elliwigy" doesn't want non-pledge comments on their bounty thread. So I figured we could set up shop here and discuss all of our crazy root rumors. If anyone is wishing to pledge for root, please go here instead: https://forum.xda-developers.com/galaxy-s8+/how-to/bounty-thread-snapdragon-usa-variants-t3598271
Awesome thanks for creating this thread hopefully we will have root soon.
So I heard lasts years S7 snapdragon root wasn't that great is that true? I had the 935F which had roms, kernels, custom recovery etc.... Root was achieved on the snapdragon S7 in a different way... Did they get twrp and roms or just root?.... Definitely keeping my fingers crossed watching these threads

It had a bunch of overheating issues and i think some features may have been mia. the same exploit isn't available here, yet, because it relied on an early build of the 935u model, and there is no such build found for these phones, yet.

It used a special engineering kernel. That is purchased by certified Samsung repair shops. It was basically worthless. It made the phone run so poorly.
It Never got true root twrp. Doubt the S8 line will either.

temp root means no TWRP u could flash some stock roms with flash fire but usually made the lag battery and overheating worse for s7e

K... Thanks for clarifying.... So if by chance we do get root most likely a bigger challenge to unlock the bootloader/add custom recovery ... I guess the thing that pisses me off is the "U1" got lumped in with all the carrier "U" varients... Both have locked bootloader... I've always used exynos Galaxys on my GSM network never had connection issues... Mostly my fault cause I didn't get the international....Any recommendations for youtube ad blockers I've tried adclear but can't downgrade my youtube for some reason...

I actually think if we get either root or bootloader unlock we will get both. With how Samsung has the device locked down it is going to take someone finding a new vulnerability that allows to unlock the bootloader or root the device. But it could take a long time to find. Too many lines of code to even count.
Other option is the someone at Samsung releases the kernel source code or some sort of bootloader unlocking software. Right there is a group of debs working hard at it but they are not close. I'm rooting for them but I would not hold your breath.
Also most of the new phone will never get root anymore. LG, Motorola, Google, Samsung, HTC all are going to be completely locked down this year.

I've seen the term "temp root" going around. What is that exactly? I want to move a user app into my system folder to make it a system app, and I believe I need root to do this. Is there any way this is possible to do without a full root and bootloader unlocked?
No. "System" is read only.

I have the SM-G955U on Xfinity Mobile, and they will unlock the bootloader out of the box, as stated in their policy. Just giving everyone a headsup, if you want to try something new. Even funnier, I am doing a 24 month payment plan for my device, with 1 gig data (always on wifi, so it works for me) and my monthly bill is 26.42 lol.
With a unlocked bootloader, you can do an official CF Auto Root right now.

Do they physically touch the device and do it in front of you? Or does it come out of the box unlocked? I'm trying to see what I can dig up.
Edit. It seems the device came shipped with a eng bootloader. @elliwigy do you think we can use this to our advantage?
