[AT&T Samsung Galaxy S 5] Zorachus:
Amen brother, still gotta go M8 over S5. The One M8 being so developer friendly is a major selling point, and worthy of supporting HTC the underdog, you can have a stock ROM, a Tweaked Sense 6 ROM, or a GPE ROM, different kernels for OC the processor, or underclock it. HTC allows pretty much total control of the One M8 is you want.

Samsung + U.S. Carriers = Nazis, locking it down tight, zero control of your phone. Juts root at best, to do cosmetic tweaks.

Is the S5 better than the One M8 ? Yeah, maybe, but not by much. The M8 does have the better battery life, which to me is #1 most important. But the S5 is waterproof, it has a brighter screen, well that's about it.

How to check if bootloader is locked

On S5, how can I check if bootloader is locked?

Can anyone already received the phone confirm if bootloader is locked?

Thanks
[AT&T Samsung Galaxy S 5] djkinetic:
When the device boots up theres usually a little padlock on the screen if its closed its locked if its open its unlocked, this being ATT though read on.

Its ATT they lock down every phones BL, let me take you on brief history, the last Galaxy on ATT to ship with BL Unlocked was the S3, the next yr S4 shipped with a locked BL, but briefly the initial batch of S4 had a vulnerability that could be exploited, that exploit was named Loki (which acted as a BL bypass but not unlock), which allowed custom recovery, roms and kernels, this was patched by Samsung later on, as a result any device recent device from Samsung no longer can be exploited via this method. Note 3 rlsed this past yr Locked, no loki and no progress as of this day with unlock for its BL, does have Safestrap (works by treating a spare partition as /system2) which allows for Custom STOCK roms but not AOSP or custom kernels (at least I havent seen any). If you want to have a picture of what Dev on the S5 ATT is gonna look like look at the Note 3 ATT section. The chances are very slim a BL unlock/true bypass comes out for the ATT S5.

Other non Samsung phones, LG G2, shipped locked BL on ATT, initial 4.2.2 BL was Loki exploitable, patched in 4.4.2 Stock. M7 Shipped Locked BL, however unlockable via HTC Dev. M8 shipped Locked BL but again unlockable via HTC Dev, Moto X locked BL however I have heard reports that Moto Dev unlocks carrier devices now.

In short it is ATT policy much like Verizon to ship their branded handsets with a locked BL, unfortunately Samsung does not off any way via themselves to unlock any of their carrier branded devices....

As such never ask if ATT Phones are BL Unlocked, assume they always are from now on. Know which manufacturers are relatively Dev friendly currently HTC and Moto seem to be.
[AT&T Samsung Galaxy S 5] Martinjv71:
Um mm the S4 still has Tons of development... lol Tmobile was never a savior..they were and still are inferior with speeds coverage and especially market share..I know 2 out for 50 people that still use The slowbile.
[AT&T Samsung Galaxy S 5] yoonus:
I watched couple to unboxing videos. None of then had the padlock sign on the boot screen.

I full understand ATTs plan for future. Knowing M8 bootloader was locked and HTC provided an option to unlock it, we should all petition Samsung to provide a means to unlock the bootloader.

That I feel is out best option than running around ATT. They can on longer say its ATT because HTC provided an option for M8.

Time to hit Samsung facebook and twitter account.
[AT&T Samsung Galaxy S 5] djkinetic:
Good luck with that, won't have any effect in the current term...I remember the days of the Moto Atrix, bunch of users complained and petitioned Moto said they would make unlock solution available for the phone, they never did...BL only got unlocked due to an employee leaking an engineering bootloader...3 yrs later Moto finally has Moto Dev setup to unlock the moto X
[AT&T Samsung Galaxy S 5] dca1970:
I have at&t s5. It has unlocked pad lock icon on boot screen. Does that mean bootloader is not locked?

I will take back everything I've ever said about this phone if it is actually unlocked...but ATT has been requesting manufacturers to lock their variants for the last 2 years

[AT&T Samsung Galaxy S 5] scott14719:
That will limit any known work-arounds drastically. The last "permissive" status I can remember was MDL firmware for the S4. After that no bootloader work-around has been successful.

Just an FYI - T MOBILE phones work on ATT Network - If you haven't already purchased the ATT S5 and you want to - buy the T MOBILE Version and unlock it to run on ATT - The T MOBILE IS unlocked - I just ran CFAutoroot and it rooted no problem.

Whatever you do - good luck...
[AT&T Samsung Galaxy S 5] 21cdb:
Are there any hardware differences at all or will the T mobile phones work with every single AT&T frequency for not just LTE but 3G/HSDPA?
[AT&T Samsung Galaxy S 5] CZ Eddie:
Yes, but many people who run the TMO S4 and Note III on AT&T network have been reporting random reception issues.

Whether that's actually true or they're just being dolts, who knows. Not worth the risk though. And I'd rather have a true unlocked bootloader. The TMO guys are not going to be running AOSP anytime soon, if ever.

And to me, the MOST important thing is being able to install a TWRP recovery so I can easily restore a full backup after I mess something up.
[AT&T Samsung Galaxy S 5] mocsab:
I can't speak for anyone else but I know I had a NOTE 3 (TMOBILE PHONE) on att and I had awesome connections - Great Data - no problem calling - very fast - up to 40MBS in some areas - at home around 10mbs - now that is me in the areas I lived - but I wonder if it wasn't somewhat in "their minds" ? I never noticed any difference between an ATT Phone and a TMOBILE PHONE in terms of connectivity or speed on att network.

(and TMOBILE NOTE 3 - S4 and S5 have UNLOCKED bootloaders - with full TWRP or CWM support for at leas the note and s4- I am sure twrp and CWS will be coming to TMO S5 soon enough - if I were you (and I know I am not) I would get a TMO phone and be done with it - but that is just me.

3G - 4G - LTE - the whole shebang - not an issue - at least not for me in Milwaukee - (or anywhere in WIsconsin that I traveled or in Chicago and northern Illinois - Indianapolis and Pittsburgh (all cities I ahve traveled in the last year)
[AT&T Samsung Galaxy S 5] 21cdb:
How about flashing ROMs on a T mobile phone when you intend to use it on AT&T? Do you have to install an AT&T modem (I would assume not) or at least add the AT&T APNs? If so would you have to do that every time you flash?
[AT&T Samsung Galaxy S 5] bookmonke:
Yes no problems, I was using a Tmobile Note 3 on AT&T and could flash whatever I wanted but had to input the APN each time.
[AT&T Samsung Galaxy S 5] mocsab:
I recieved my TMOBILE S5 Yesterday - I flashed Chainfires CF Auto Root for the S5 today - Despite what the "OFFICIAL" at TMOBILE Customer Care said - and despite all the rumours being talked about on XDA - the TMOBILE S5 does not have a locked BOOTLOADER.

I am not trying to say "Told you so" - but really am only saying that we have to be careful pushing information that may turn out to be incorrect - rumors and comments from people who really don't what they are talking about - well - it just causes too much anxiety for everybody - and the more often it is repeated - the more "truth" it seems to carry - but the real truth is - we won't ever reallly know until we have the device in hour hands. -

---------- Post added at 03:45 PM ---------- Previous post was at 03:43 PM ----------
[AT&T Samsung Galaxy S 5] 21cdb:
By whatever you wanted do you mean international ROMs as well? I guess one concern I have is that the T-Mobile device is going to be some special hardware that isn't compatible with the international ROMs and because the other carriers are bootloader locked the support will be minimal. But if I can flash international ROMs (like we could on the S4) and just add the AT&T APN then I think I'll just go get that T-Mobile S5 and be done with it like you said.
[AT&T Samsung Galaxy S 5] thardie:
This is particularly interesting. When you compare specs from Samsung's website, seems the T-Mobile version is everything the AT&T is AND MORE. The TMobile frequency list has all the AT&T frequencies and more:

T-Mobile: http://www.samsung.com/us/mobile/cell-phones/SM-G900TZKATMB

AT&T: http://www.samsung.com/us/mobile/cell-phones/SM-G900AZKAATT

AT&T LTE: Bands 1/2/3/4/5/7/17 3G: 850/1900/2100MHz

T-Mobile LTE: Bands 1/2/3/5/7/8/4/17 3G: 850/1700/AWS/1900/2100MHz

Seems to me anyone who can deal without having a contract should be buying the T-Mobile and using is on AT&T...
[AT&T Samsung Galaxy S 5] CZ Eddie:
Yep, one guy with a TMO S5 already flashed Phillz (CWM) recovery onto his TMO S5. He used the International recovery I guess.

Proof.

Btw, the "G-900T" model # in that pic is for the TMO S5.

[AT&T Samsung Galaxy S 5] dustintinsley:
How do you sim unlock the TMO version to use with At&T?
[AT&T Samsung Galaxy S 5] thardie:
Well, I would think when you pay full price they would have to sell it unlocked. I just called a T-Mobile store and they tell me they won't do it, and you have to wait 40 days and then customer service will unlock it.
[AT&T Samsung Galaxy S 5] dustintinsley:
I called two different stores and they both told me that the sim is locked and that is buying at full price.
[AT&T Samsung Galaxy S 5] Baldilocks:
All U.S. carrier versions of the GS5 are bootloader locked according to AnandTech.
[AT&T Samsung Galaxy S 5] djkinetic:
Tmobile is confirmed not locked as CF Root works.
[AT&T Samsung Galaxy S 5] sdlopez83:
It can be rooted and still be locked.
[AT&T Samsung Galaxy S 5] jd1639:
Can you put a custom recovery on? That's what I'd be interested in. As said above, you can be locked and still get root

Sent from my Nexus 5
[AT&T Samsung Galaxy S 5] djkinetic:
No not with the way CF Root works, CF root modifies the stock recovery of Galaxy Devices, it then uses Odin to flash SU and flash the Stock Rom over again, if the BL is locked CF Root will either fail to flash, fail to boot, or worse brick the phone, the reason is once you modify anything from the stock Odin Tar, it doesnt match the signatures of the original files. This then flags Odin along with the phone if the BL is locked and says hey this isnt official, once this happens Odin will usually error out and wont flash the custom file. If you doubt me go into the CF Root thread, Chainfire explicitly states this.

On Tmobile someone already put the KLTE (international version) of Philz recovery on their TMO S5....i just placed an order for the S5 on my TMO account after seeing that lol.

[AT&T Samsung Galaxy S 5] bookmonke:
Looking at T-mobile version too, hate to but at least want root, and like someone else said don't flash modems, I over looked that in last comment. The note 3 worked great on AT&T with the APN added, could flash what I wanted and even had the phone repaired at Samsung with Knox tripped and it came back un-tripped. Phone showed up on the online bill area as AT&T SM900T
[AT&T Samsung Galaxy S 5] camry89:

Will we be getting root soon?
[AT&T Samsung Galaxy S 5] Greycloak42:
No. This has been available. Chainfire's method will not work with locked bootloaders. Hopefully someone is working on an exploit based root.

Your right my friend has T-Mobile s 5 and he has rooted it already, at&t sucks I am going to the HTC one m8 the first of the month bye bye samsung
[AT&T Samsung Galaxy S 5] mocsab:
I always thought the S5 would be unlocked despite what every body said was "proof" that it would be - in the end - it was unlocked and it just shows you that you CANNOT assume that the customer support people at the carriers know what they are talking about beyond the basic things about our phones - not saying they are all dumb or anything - I just don't think a majority of them even know what a Locked Bootloader is. (my Guess is they were all thinking KNOX - but then KNOX doesn't have anything to do with the bootloader being locked)

They all said it wolud be locked. THEY WERE WRONG. :)

Thankfully.
[AT&T Samsung Galaxy S 5] PunchLick:
I am going to sell my s5 for something else if nobody gets root available. I have trust and patience though.

Maybe after a couple months with no progress I will change to something not locked down.

They sell you a 600 dollar phone thats locked down and still partly theirs. I may end up just swapping from AT&T and Samsung all together.
[AT&T Samsung Galaxy S 5] TheSheibs:
I heard the note 3 had a locked BL. there is a root for it. I an wondering if anyone knows if the method used for the note 3 would work in the s5.
[AT&T Samsung Galaxy S 5] sdlopez83:
S5 bootloader is certainly still locked for att and Verizon.
[AT&T Samsung Galaxy S 5] ExTREmE99:
ok, since this hasnt been mentioned here yet. but in the ART thread, people who have changed to the ART runtime have noticed that the bootscreen changes to the below:

reminds me of a nexus splash screen when you manually unlock the bootloader. can anyone confirm the bootloader screen also shows the same for regular davlik runtime?
[AT&T Samsung Galaxy S 5] JediSooner:
Just working through an idea here... how many of you would pay AT&T for the option of unlocking the bootloader and having a flag on that line on your account to prevent you from warranty returns in the event of a hard brick? $30, $50, $100?
[AT&T Samsung Galaxy S 5] pcidiot:
I'd pay but it wouldn't be much. 20-30 seems reasonable. I would think 50 would be the max most would want to go it just does not seem right to pay 100 half of contract price to do it. Why do you ask? Do you have At&t contacts?
[AT&T Samsung Galaxy S 5] JediSooner:
Yeah, I think $100 would be a bit steep. Then there's AT&T Next to consider... you don't actually own the device until all 20 payments are made. Not sure if AT&T would unlock the bootloader - even at a cost to the customer - on a device that's still being paid for and may eventually be swapped out for a new device. Then again, even if a returned device has an unlocked bootloader, if the device isn't hard bricked couldn't they just re-lock the bootloader and do whatever is done with previously owned devices? Not sure if Knox would have to be considered on Samsung devices either.

I work for AT&T, but not in Mobility.
[AT&T Samsung Galaxy S 5] pcidiot:
I'm not currently on the Next program but I'd think as long as the phone looks good and works At&t wouldn't care. Like we discussed in another thread when it came time for trade in most AT&T store reps. Don't even know what a Bootloader is. What ever it is they do with these trade in phones (sell as refurb. units I don't know) I am sure they can easily undo in the process of returning to stock/testing.
[AT&T Samsung Galaxy S 5] daraj:
great idea and I would pay for it, but it wont ever happen and here is why: Simply because If they unlock your bootloader then people will start reverse engineering the unlock process and eventually people will start unlocking their own phones.(which defeats all the purposes that AT&T had)
[AT&T Samsung Galaxy S 5] JediSooner:
GREAT point! I didn't even think of that possibility, but I guess I should have considering where we're talking about this. LOL. Thanks.
[AT&T Samsung Galaxy S 5] surf1:
Honestly I would pay, not a 100 bucks. But no reason they could accept 20 bucks or so to unlock the bootloader, all the people that root or just want it unlocked, there are countless owners who would do so and make a little extra revenue for at&t. And let's be honest, the chances of a hard brick happening and returning to at&t to fix is slim to none, nobody I know over the years has had a hard brick nor warranty related issue due to rooting. I mean accord to AT&T now, on these phones you root and flash, and the camera fails, or the head phone jack magically stops working.... your SOL, when we all know if stuff like that failed it was going to anyway stock. Like a friends Note 3, he went through 2 replacements initially 1 the screen failed, the 2nd had weird software glitches after a two weeks, 3rd one has been perfect. However had he rooted before, AT&T would have told him tough luck and he'd be out full price twice :silly: . I'm a car guy/truck guy, I mod all my vehicles, forced induction, custom dyno tunes etc you name it. Even under warranty no problem, as even if something happened they'd have to prove it was directly the result of the add ons, good luck doing that with cell phones lol.
[AT&T Samsung Galaxy S 5] MattMJB0188:
Don't you guys think if the bootloader could be unlocked it would have been on the S4 or Note 3?
[AT&T Samsung Galaxy S 5] karmuh:
I would. I probably wouldn't pay as much as $100, but I would easily pay $50. In all my years of using a phone, I have never once filed a warranty claim.
[AT&T Samsung Galaxy S 5] seanpr123:
Ya it won't be unlocked, we're past the stage where individual devs are able to outsmart and work around exploits by a company like Samsung/AT&T.

I was lucky enough to get a Loki S4, but not going to even hold my breath on the S5 front. I may purchase a T-Mobile S5 and just unlock for AT&T, or kinda thinking about the Oppo Find 7. Just heard today the G3 may have a removable back with battery and MicroSD, that would be an insta-buy for me too.
[AT&T Samsung Galaxy S 5] pcidiot:
I would think, this in all reality would be against forum rules and any thread using the tech. would have to be locked. If its a paid for feature. But what do I know who really reads the entire rules page. Lol
[AT&T Samsung Galaxy S 5] MattMJB0188:
I am about to dump AT&T for good, depending on how TMO's service is. So far so good. Pretty impressed. Gonna fully test it out. But we, as consumers need to STOP supporting companies like this.
[AT&T Samsung Galaxy S 5] yoonus:
willing to pay

I am willing to pay ATT to get unlocked bootloader. Definetly not $100. $30 looks reasonable. ATT get the advantage of me not retuning the phone in case it fails for some reason.

5.1" screen, 16MP camera, finger print, heartbeat sensor, ultra power saving mode etc etc. All are good. But I am back to my S3 because it has root. S5 is back in the package, ready to wake up when root is available.

Out of box, S5 boots up without any lock screen.

[AT&T Samsung Galaxy S 5] djkinetic:
LG locks the bootloaders on all their devices, the G2 was lucky in that Loki wasnt patched when it shipped with 4.2.2, the 4.4.2 update klled Loki, and as of now the G2 bootloader still hasnt been exploited truly. In order to get keep Loki and Custom recovery on stock 4.4.2 currently on the G2, they're still using the 4.2.2 bootloader...the G3 looks nice but if its not exploitable I wont be buying it. I have high hopes personally for the One Plus One.

Ahh yes you're right, shoot.

[AT&T Samsung Galaxy S 5] cciechad:
If I'm reading this right its the QCom dev kit for the SoC on our phones(including the code to generate signed bootloader images). It appears to include a QComm signing cert that might be accepted by all QComm SoC based phones. Excerpt from one of the py files in the dump.

# GenSecImage.py

# GENERAL DESCRIPTION

# Pre-processes images so they can be signed, and packages the

# certs and signatures into the image to create the signed image
[AT&T Samsung Galaxy S 5] godofwar762:
So this is pretty big then? Meaning we will get root soon hopefully
[AT&T Samsung Galaxy S 5] cciechad:
If every phone based on a Qualcomm SoC will accept bootloaders signed with this key then yes but I'm still skeptical till I see someone sign a new bootloader with it that removes the lock and is loaded on an AT&T phone. I'd have expected a takedown from QComm by now if this key was so critical to them.

[AT&T Samsung Galaxy S 5] Simer03:
Our only option is to find an exploit like the note 3... The boot loader will probably never get unlocked...it just depends on if anyone will actually try! Be patient people!
[AT&T Samsung Galaxy S 5] djkinetic:
It will take some time, as the exploit used to root the note 3 was based on 4.2.2 and modifying system, with kit kat 4.4.2 Samsung closed that exploit, so a new exploit will have to be found.
