I've read a ton of posts on this topic and I understand the general consensus is that the bootloader is locked, but has any developer confirmed this? I asked Chainfire about a cf auto-root and he just assumed the bootloader was locked. People assumed this about the tmobile variant as well and apparently tmobile didn't lock the bootloader as people are rooting as we speak. I just wondered if it was even possible to check without the firmware being released.

I would but I don't know how. I tried to Google it but didn't come up with a whole lot of info.

Need to try and flash something, but theres nothing out to flash lol.... Also ATT 99.9 percent of the time like Verizon locks their BLs, there were reports that TMO was locking it's as well but it seems the initial batch is unlocked, could change but I would count on the ATT variant being unlocked.
Guys, it's LOCKED. No, I can't confirm it, but why would AT&T say they don't support unlocked bootloaders and then ship the S5 with an unlocked bootloader? I think not.

Pretty much this, which means no root, till a new exploit is found...but how many actual ATT devs are there that planned on getting the S5

Probably not a lot. When the S4 had its bootloader patched last year development went down the drain, and fast. Everyone kept saying that the developers will unlock it, and they NEVER DID.
I am not trying to dis-respect any developers on here, but I do not like safestrap. Its no where as good as CWM-Recovery. I also loved flashing AOSP roms.

What you say makes perfect sense, I'm just saying that it would be nice to have it confirmed. With all of the back and forth between tmobile and their "Uncarrier" promotions and att's counter marketing, maybe att changed their minds to help their image, who knows, it's just a wishful dream I guess. Hopefully when sammobile makes the firmware available, someone can get Chainfire the recovery partition and he will create a cf auto-root for us to try.

Here's the problem though, if the BL is locked, cf root will most likely either not flash or not boot according to Chainfire, and if either of these happens not only are u without root, but also the knox warranty flag is tripped and your warranty is voided...unfortunately someone has to be willing to take one for the community to confirm all this.

Isn't that always the case with an unknown new device? I don't think xda would exist if people weren't willing to take some risks.
Looks like Chainfire is in irc looking for some att testers for auto-root. http://forum.xda-developers.com/showthread.php?t=2696537&page=23
Hey, I have a att s5 active rooted, what I am wondering is if I can put a s5 active Bell or telus rom on it, and if I can, does anyone have the rom that can send it to me.
Thanks

I believe the answer is no....reason being is the 870a is bootloader locked...can't flash the kernel or modem of the other rom.

I think it is already unlocked I can't remember the exact steps I took but It took forever.
On boot it says custom and shows a unlocked pad so I think that means it's unlocked
I would like to find a bell lollipop rom for it, I don't want to put any att rom on it because it locks tethering and it took lots of ****ing around to get it turned back on.

The custom symbol just means that it has detected you modified your system, it means norhing, your bootloader is still locked.

I recently purchased the G920T factory unlocked version on eBay, is it safe to Odin any T-Mobile stock firmware, any info will be appreciated, thanks in advance.
Once you above a certain firmware you can't go back. What firmware you currently on?
It is currently on G920TUEU3COK1 can I Odin to the latest T-Mobile G920TUVS3DOJC I understand that I can't go back but is it safe and will it function normally, thanks for the reply.
i have this same question because from what ive read 3COK1 is for Cellular South (aka C Spire). while the 3DOJC is for Tmobile, both under the G920t firmware. are you also on tmobile network with this phone?
What are the benefits of flashing T-Mobile firmware on the USA factory unlocked phone? I have this phone on T-Mobile and wifi calling works. I also get great reception. I assume this phone will get Marshmallow months before T-Mobile releases their build

Does this firmware that the device came with (G920TUEU3COK1) have any carrier branding or logos anywhere? Id like to switch if it doesn't have carrier branding

Are you getting LTE on it.
So I flashed the C Spire firmware and it asked for an unlock code. I flashed back to the original tmobile firmware and it is still locked although it was unlocked before, but the device unlock app says its ineligible for unlock now.
Anybody else encountered this?
Call t mobile customer service and ask them. They can adjust their servers and then the unlock app will work.

I'm sorry I misread that this a different model. I'd try to contact the user stifilz to unlock.

Were you able to get it unlocked? I plan on doing the same, flashing the unbranded to my t-mobile that is currently unlocked.

I'd advise that you dont.
To unlock it I had to flash back to the original tmobile rom. From the tmobile rom, the device unlock app failed in different ways.
After i called tmobile over and over I got it unlocked (like 2 hours of calling).
Hurts my heart to see all the tmobile bloat, especially when i dont even live in the US, but at least my phone works

Thank you, I guess I'll just sell this one and buy an international unlocked, glad to hear you got your phone working.
Anyone successfully updated this G920TUEU3COK1 US factory unlocked version to marshmallow? I have Samsung Pay, wifi calling, etc. all enabled on mine and would like to update, but also keep the unlocked non-bloated firmware.

Which method did you use to update the G920TUEU3COK1 US factory unlocked version? Does using the Tmo firmware risk un-unlocking the phone?

Okay so i have read a few thread posts but all this seems a bit too confusing. Here is the situation. I bought a used S6-G920T which is unlocked as of now, i don't know what method was used to unlock it since i bought it pre unlocked. My sim(Non T-Mobile) is working fine. I am on 5.1.1- BASEBAND: G920TUVU3DOJ7, what i want to do is update to marshmallow, the official OTA isn't really available as it says the system was tampered with. I want to know if it is safe to update to 6.0.1 via odin without losing my unlock. Thanks in advance to anyone who bothered to read through.
BTW as of now i don't have root access.
What do you mean when you say you're unlocked?
You can use Odin to update the phone to newer baseband and bootloader; you can then use Odin to flash TWRP, and install the ROM of your choice.

I am talking about carrier unlock. I currently don't have any carrier restrictions. Will update cause my phone to become relocked?

It shouldn't, no. You should be able to update and still use your phone on the carrier of your choice.

What method did you use? I don't imagine it would...of course, if you flash a stock TMobile ROM, some TMobile features may not work on another carrier...

That is the issue I bought it unlocked(used) so no idea what method may have been used. I might just go ahead and update. Thanks for the help.

I'm pretty sure the phone unlock has something to do with the IMEI of the phone being tied to the carrier. If it is unlocked, you should be able to use it on any carrier. It sounds like the process takes place in a special partition that is at the lower levels, like the bootloader, and does not change regardless of what software is used on the phone. I'd say just go for it and update, I can't see any reason why it wouldn't work, even after an Odin flash.
I picked up a Note 8 thats still locked on At&t and Im planing to flash it over to Verizon for use on their network. The guy that sold it to me said he was working on getting it unlocked and im prayinh he comes through. If I understand what Ive read so far I should be able to flash it over to Verizon while its locked, just that it will still be locked afterwards which is fine. Is that true? Will I encounter any issues or would I be better off waiting until its unlocked first?
And if anyone knows an easy way to unlock it im all ears. Thanks a bunch.

As long as it's carrier locked to AT&T there's nothing you can do.
While you can flash the VZW ROM, your device will still be locked to AT&T. Have to wait for them to unlock it.

I understand that, but I was wanting to play and get a jump on the game, if I flash it to VZW will I have any issues unlocking it with ATT after the fact? I'm just wanting to get the VZW firmware loaded and the phone setup so once it's carrier unlocked I'll be ready to go with Verizon.

I don't know. While it isn't applicable to our device, I do know that if one is running a custom ROM, often the SIM unlock code won't work.
Just in case anyone else has the same question, sense I'm sitting on a samsung locked Note Edge that was legitimently mine I decided to play it safe and wait it out. Original owner got it unlocked for me today so now it's time I can play.
