I can flash and configure any s5 variant to work on a different network the boot loader is irrelevant.... almost all s5 variants aside from a few are all internally physically the same.

Hey everyone,

I am currently running a straight talk variant galaxy s5, which is exactly the same as the verizon variant s5, just without the locked bootloadet. I know this for a couple of reasons.

1. I was able to root and flash twrp via Odin without safestrap.

2. I can boot into recovery without safestrap.

3. I can flash roms and make back ups in twrp without safestrap.

4. I can flash any verizon variant s5 rom, and they work flawlessly.

In fact before I flashed a rom my phones model number said sm-s902L now it says sm-g900v. Not only that but YouTube before I flashed a rom would only let me play upto 720p, now it let's me play upto 1080p. And it's not a type o, it is actually playing in 1080p. It also recognizes and let's me over clock the full quad core processor. And I can verify that I bought this straight talk s5 from Walmart directly, and unboxed it out of a a walmart /straight talk box.

not to mention the se status is set to permissive
[AT&T Samsung Galaxy S 5] Rakuu:
OK what is the point of you posting this?
[AT&T Samsung Galaxy S 5] kxhan15:
This whole thread is full of people saying that all s5 bootloaders are locked when they arent. And anyone with any adb experience and an email account can get an oem unlock code directly from samsung. Safestrap is really for people who don't know enough about android os to be messing around with it. And they usually aren't willing to learn basic adb commands. This is why these threads are so full of people trying flash back to stock after they think they bricked there phones.
[AT&T Samsung Galaxy S 5] s8freak:
You're absolutely wrong.

The bootloader on the AT&T is locked down tight and cannot flash TWRP or any custom kernels.

Before the last update there was an exploit that allowed root and the use of SafeStrap to flash T/W Roms using stock kernel only.

[AT&T Samsung Galaxy S 5] kxhan15:
That's funny because I am running cm13 on my sm-g900v right now as we speak. In fact I flashed TWRP via Odin and SuperSu thru TWRP to gain root. It's really funny because I have NEVER had to install SafeStrap. I wonder how that's possible??? Ohh yeah, I have an unlocked bootloader thats why. You can email support at samsung mpobile . com just send them your model number and imei and ask for your oem bootloader unlock code. They email you back with the code in about a day, and thank you for your business as well.
[AT&T Samsung Galaxy S 5] s8freak:
Prove it...what you have is a straight talk phone that isn't a Verizon device that didn't come with the locked bootloader that the Verizon device would. Then you got the code to sim unlock your device to use the Verizon sim.

Verizon isn't going to send anyone a code via email or any other way to allow the bootloader to be able to be "unlocked"

My S6Edge + came unlocked so I could use my AT&T sim but the bootloader wasn't unlocked.

If what you're saying is true anyone with a Verizon S5 can simply send an email to sammobile and get a "code" to unlock the bootloader.

If that was the case then why haven't they??

[AT&T Samsung Galaxy S 5] kxhan15:
First of all you are right, this is a straight talk s5, but when I pull the battery and look at the model number it says sm-G900V which is a verizon s5. But since it had straight talk software installed its bootloader was already unlocked. And I never said at&t or verizon would give you an unlock code, I said Samsung will. Prove it... OK here ya go.. just email samsung your Imei and model number and ask for your "oem bootloader unlock code" and see for your self. And as for why everyone isn't doing it, well... most of the people in this thread apparently don't know how to use adb or fastboot. The hilarious thing is it's really just a couple lines of command and you don't even need to be rooted. Just enable developer options and USB debugging. Just plug your device into your pc, open an adb command window on your pc. Type in "adb devices". Adb will show your device Id if you have your drivers installed. Then type "adb reboot fastboot" you'll have click ok on your phone to allow it. But the your phone will reboot into factory or "stock" recovery. Once it is done, on your pc type "fastboot oem bootloader unlock (and the code you get from samsung)". It might take a few seconds but Once its done your device will automatically reboot. Unplug it. You will know it worked because your device will be completely reset. Now go get Odin version 3.09, twrp 2.8.7.0-klte.img and SuperSU-v2.46.zip. Install odin. Open odin. Unchecked the automatic reboot option in Odin. On the right hand side click the button that says "AP". Select you twrp file. On you phone, power off your phone. Reboot your phone into download mode (hold down volume down, home and power buttons at the same time). Once in download mode, plug your device into your pc. Wait for it to show up in Odin. Once it does, make sure your correct twrp file is in the AP window in Odin. Then click the start button in the lower right corner of Odin. Once its done and says "reset" in the first com window in Odin, unplug your device. Power it off, you may have to pull the battery. Once you have it powered off, power it back on this time holding the volume UP, home and power buttons all at once. You'll boot into twrp recovery. From here you can flash SuperSu if you need to, roms, make and restore back ups. All without safestrap. Because your bootloadet is unlocked now.

Some samsung devices, even on verizon and at&t don't require an unlock code. On those you can just type "fastboot oem bootloader unlock" in adb without the code and it will work.

And just for the record, this works to relock your bootloader as well.

[MENTION=5072378]s6freak[/MENTION] I see you have a high post count and a lot of thanks as well. Which tells me that you help a lot of people out and have some useful knowledge. Thank you for helping the xda community.

But don't mistake my low post count and low thanks count for me being some sort of noob. I just don't have very many questions. About me.

I have a degree in software development and engineering. I also hold both Google and IOS developer licenses. I am also a state and federal recognized expert in mobile forensics. I have 7 apps on the play store and app market for my employer. I am well versed in adb, fastboot and generally all aspects of the android SDK. I compile and decompile apks nearly every day. I decompile and port roms for myself all the time. I have been a member here at xda for nearly 10 years and love it. I just don't put stuff up here because I don't have the patience to answer a lot of questions. That's where members like you come in, you are great for helping the community. I just don't have the time or patienc.

I am running my own port of cm13 android 6.0 on my sm-G900V right now. And I am working on a safestrap flashable port of cm13 for verizon and at&t .
[AT&T Samsung Galaxy S 5] s8freak:
I know how to use Fastboot and adb I've owned more than Sammy devices. I also know a lot of very knowledgeable developers on this site as well.

Unlocking the bootloader is more complicated than how you're explaining it. I also know how to use Odin.

Since the reason for AT&T and Verizon asking Sammy to lock the bootloader for what they deem "security " reasons I find your saying they'll just email you the unlock code to be counter to why they're locking it down in the first place.

[AT&T Samsung Galaxy S 5] s8freak:
Exactly what I was saying.

There's been some very top rated guys on XDA trying to break the bootloader and it can't be done.

GeoHot the guy who gave us towelroot for the G900A before the updates closed the exploit is now working for Google it's my understanding.

There was quite the considerable bounty for the person that could unlock the bootloader and to my knowledge it's never been claimed.

I had the S5 G900A and my wife has one now and actually I've had the S series from the S2 up to and including the S6Edge Plus which I own now. Plus I've owned a OnePlusOne and I also have the OPX which requires some knowledge of Fastboot and adb to unlock those bootloaders which I've done.

The Verizon bootloader is locked down as well as the AT&T Variant.

It has everything to do with those carriers not so much Samsung.

Go and read what the Verizon peeps say in the G900V threads.

I have an unlocked G928C international S6Edge Plus that came sim unlocked so I could use it on AT&T but the bootloader can be unlocked as well in developer options. That option isn't available on the G900A as my wife's G900A will show

As a quick aside since its a little on topic with the discussion here, but do you think it's be possible to use whatever hook multisystem uses to get safestrap working on lollipop? hasbdr says MS is based on SS, I looked through the files for both and it seems they are both using very similar processes for jumping in before boot completes, seems at least theoretically possible to me but at the same time too simple to not have already been tried.

[AT&T Samsung Galaxy S 5] Zorachus:
Exactly. I'd rather get the S5, but with the U.S. Carriers + Samsung being Nazis, and no custom Recovery allowed, only basic rooting, which isn't even available yet.

And where is Samsung's GPE S5 ? HTC made a GPE One M8 right away at launch, and with the One M8 being so open, you can now flash the GPE ROM on a carrier bought version. S5 will take quite awhile to get a AOSP or Nexus type ROM.

I just can't support and buy the S5 if no ROM'ing coming, like my S4, it's a good phone, but sucks balls with no true ROM's, and not the safe stuff, that's not the same.
[AT&T Samsung Galaxy S 5] noahk11:
It probably will be, no one has a AT&T S5 yet but seeing the track record and articles like this, its probably going to be locked down. Its quite infuriating. However T-Mobile has not been locking theirs down so you could just buy one from them and unlock it. Something does need to be done though, AT&T should not be locking down devices WE paid for and that are OURS. They never respond to petitions though, they must not care about their customers I guess.
[AT&T Samsung Galaxy S 5] slapdaddy:
AT&T doesn't care at all - as long as the money keeps coming in. I was lucky enough to get an S4 near launch so I've been enjoying all the AOSP I want since I've had this phone. But seeing how development for the S4 is moving at a turtle's pace after they patched the bootloader, I'm going to go with the M8 this time around.
[AT&T Samsung Galaxy S 5] CZ Eddie:
The HTC One M8 has already been unlocked and CM11 is well on its way to being developed/installed on the M8.

AND, HTC/TMO have already released the source code.***

HTC is being extremely Dev friendly right now. Samsung is just giving everyone the middle finger.
[AT&T Samsung Galaxy S 5] rachelm920:
Back in my T-mobile days I had an HTC Amaze (circa 2+ years ago) and eventually we were able to unlock the bootloader and flash CM variants. Why can't the same thing happen for the S5?? I'm sure there's someone out there who has the knowledge-base to do this... Mine shipped this morning. I'm hoping there's some kind of dev for it or I'm gonna be a Pissed off Android user. If I wanted to be locked down I'd buy a damn iPhone. I've been rooting my Androids since I had the Motorola Cliq and "motoblur" LOL
[AT&T Samsung Galaxy S 5] sdlopez83:
Moto atrix had the same deal, was an awful experience, had to wait 3.5 months for the unlock. Not cool at all. Wouldn't do it again.
[AT&T Samsung Galaxy S 5] sabre31:
The only reason Atrix was unlocked was because somebody working at Motorola leaked the Engineering unlocked bootloader otherwise it would never happen. These boot loaders are locked via certificates and changes of them getting unlocked is slim to none and will take a really long time if ever by then most folks have moved on to other phones.

You should not be buying an S5 if you want to flash ROMs if that is key for you then get another phone that is dev friendly like M8 or Nexus 5.
[AT&T Samsung Galaxy S 5] sdlopez83:
Right, it was a fuse issue if I'm not mistaken. And then We got kholked. Brings me back..

Is there any information on the status of the US Cellular Galaxy S5 bootloader? And does knox mean that it is impossible to install a custom recovery and custom ROMs or just that it will trip knox to 0x1 and void warranty?
[AT&T Samsung Galaxy S 5] jd1639:
If I were a betting man I'd say the bootloader will definitely be locked and no custom recovery. But I'd say that there is a possibility of some custom roms. Good chance that Knox will be tripped.

I really couldn't care less if knox is tripped. I'd rather have a phone I can modify than a phone with usable knox and a warranty.
[AT&T Samsung Galaxy S 5] sabre31:
Then S5 is not the phone you want . Based on your need to have Roms a more better phone for you would be htc one m8. Fully dev friendly . Samsung has become the apple of android world with their locked phones.

I'm walking in on Thursday to local AT&T site and trading on for m8. Same speed. Unlockable. Sexy aluminum body and no dumb gimmicks. Even Samsung's commercials piss me off now
[AT&T Samsung Galaxy S 5] donharden2002:
And it comes with 32gb of storage instead of the 16 on the galaxy s5.

Just wish it had a higher mp camera.

Don't get me wrong, the camera takes good pics for what it is but I think HTC needs to step it up in that dept.
[AT&T Samsung Galaxy S 5] sabre31:
I was really looking forward to S5 but after being burned on S4 and Note 3 with locked bootloaders I missed the roms. Also paying premium price for 8GB of useable storage is not cool. This time around I am going with an M8 also. It has crazy dev support already and HTC is dev friendly.
[AT&T Samsung Galaxy S 5] Superguy:
I chose the M8 over the S5 and I'm very happy I did. With the thing being completely dev friendly, the international/dev versions being based of the AT&T version, and the amazing amount of support it's gotten, you can't go wrong.

I ordered an S5 for my wife as she prefers Samsung phones, but she's not much of a power user. If I could even root and just get rid of some bloat, she'd be happy. But even then, she's fine with it stock.
[AT&T Samsung Galaxy S 5] djkinetic:
Weighing in here, I've had alot of mobile devices in the last 2-3 years, the last Galaxy that truly shipped with an unlocked BL on ATT was the S3 and that was great, next year got the m7 and s4 on ATT, m7 got s-off and was unlocked via HTC Dev no issues whatsoever and amazing Dev support (still does). The S4 luckily i got it at launch and luckily Loki was made available for it by djrbliss. Unfortunately later on the exploit Loki used was patched by Samsung and as such any later S4 will never be able to be lokied with that exploit..Bootloader unlock has never been found for the US Carrier S4 and likely never will unless someone leaks the signing keys/certificates...result Dev support slows to a crawl...yes Bootstrap can allow you some mods but not the complete freedom to choose between GPE/AOSP or TW...The S5 will 100 percent be locked on ATT and without loki being an option to exploit and the chances slim to none on a bl unlock, Dev support for this device is going to suffer....

Personally i'm a fan of GPE/AOSP only oem skin I can stand to use is Sense, TW is just to kid like and cartoony for me, much like my G2's stock software (thank god it was initially Loki exploitable, has been patched with 4.4.2 stock) For the reasons above along with the added complication of Knox Qfuses I decided to skip this round since I know I'd never be happy with a locked down phone....Luckily HTC has been a bit more dev friendly which is why I used one of my upgrades on the M8 over the S5 (S-off and unlocked via HTC Dev) anyone who likes to have control over their phone on ATT should look elsewhere than the Galaxy line....There more than likely will b safestrap but its just not the same as having full control of your device.
[AT&T Samsung Galaxy S 5] seanpr123:
Completely agree with everything you said /u/djkinetic, however I just can't give up that removable battery...

Very glad the MicroSD is making a comeback (rock on HTC), but I value the swappable battery over most other things. Being able to swap while traveling or out camping is a major plus in my book. Plus I've had batts last less than 2 years before the capacity is shot and I'd rather not have to send my flagship device back to the OEM to be charged up the rear for a simple replacement.

Which is why I'm taking a good look at the Oppo Find7 this year (don't mind paying full price). It's a bit large (Note 3 territory I do believe), but has all the requirements and is incredibly developer friendly. Will be looking into the International S5's too, will those not have 4G here? What about warranty support?
[AT&T Samsung Galaxy S 5] djkinetic:
Depends on the bands that the international S5 come with, warranty would come from Samsung instead of ATT...If you take an Unlocked international version to ATT they'll laugh you out the door and say send it back to Samsung.
