Does a factory unlocked Galaxy s5 have an unlocked bootloader - Galaxy S 5 Q&A, Help & Troubleshooting

There are some galaxy s5 phones coming up on the local Craigslist that say factory unlocked. Would these have unlocked boot loaders?

Depends on if its the international one. Cause you can factory unlock an AT&T one. And that doesnt have an unlocked boot loader either way.

Verizon and ATT lock their bootloaders. Most if not all other North American S5's will have unlocked bootloaders. In most cases, The TMobile version is the most unrestricted and capable hansdset. Unless you need a CDMA phone (Verizon, Sprint, US Cellular).
"Unlocked" usually refers to SIM locks.
For completeness there are also Developer model phones for Verizon /ATT that do have unlocked bootloaders. You won't see those very often. They have a different part number and their own firmware. Samsung does not have a good history of providing timely firmware updates for Developer models.

[Q] Unlocked bootloader?

I have read that all Note 3 have locked boot loader. If I purchased an unlocked Note 3 from i.e. Negri Electronics, would these come with an unlocked boot loader?
Are there any reseller that sells a Note 3 that is has both sim and boot loader unlocked?
Samsung does not sell locked bootloader like HTC
sim locked is something else, and yes u can buy ig sim free (unlocked) or just buy the unlock code
Only Verizon and ATT have locked bootloader I think, as post above states, all are unlocked by default.
AT&T's Note 3 bootloader is locked, Verizon's is too, but Verizon does offer developer edition, which has unlocked bootloader. T-Mobile's Note 3 bootloader is not locked. I'm not sure about Sprint, but you dont want to be Sprint customer anyway.
Disregard posts from people, who don't understand the difference between locked bootloader and network carrier lock and make posts about unlocking and unlock codes.

[Q] is the bootloader going to be unlocked?

Has samsung announced that they will unlock the bootloader? was the s4 with locked bootloader also?
Correct me if I'm wrong, but I think Verizon may be the only one with a locked bootloader.
I actually don't know... if it's only verizon then that's cool.. i am going to buy the unlocked carrier version.
edit: seeing no custom rom, I thought the bootloader was locked
Yea, I'm pretty sure it's just the Verizon model. Every other model has plenty of roms.

The bootloader is already unlocked. On my phone and most other S5's as well. You are apparently making some assumption about some particular S5 variant. A minority of carriers do lock bootloaders, but you didn't even tell us what model of S5 you have or are referring to. You should give some context so that we know what you are talking about.
edit: I see that you implied in a follow up post that you meant Verizon. The bootloader on a Verizon S5 is locked at the behest of Verizon, not Samsung. Samsung doesn't lock the bootloader for TMobile, Bell, Rogers, Telus or hundreds of other carriers. Pretty much just Verizon and ATT and a few sundry CDMA carriers that are that restrictive.
There are tons of custom ROMs for carriers that are more reasonable. You can use Safestrap to emulate a limited number of ROMs on Verizon but it's your choice of carrier that is hampering you here.

ok thx guys I am getting the unlocked/carrier free version .. so should not be a problem thx

Will this help?

Help with what? It would be a good idea if you specified that. If you mean unlocking the bootloader or gaining root on the carrier branded S7s, then likely not. These unlocked phones do not have unlocked bootloaders. They are simply SIM unlocked so they can work on any carrier. That's what they mean by unlocked.

Its Verizon.
The model is SM-G935V
I think the only solution is to change the logic board.
I tried almost every 3rd party unlock site, contacted Samsung and Verizon but no luck.
Ummmmmm I think the u firmware is carrier unlocked and nor does Verizon lock there phones so it should be unlocked dude

The "U" model is the newer model that Samsung introduced on June 30 of 2016. It is UNLOCKED for North American carriers. It will run all of the big 4 (AT&T, Sprint, Verizon, & T-Mo) based on which carrier's sim card you put in it. Samsung introduced similar to some of the Motorola models or the Nexus/Pixel models that can be taken from carrier to carrier. That is ONLY true of the 935U. If it does not say U, it is not the North American unlocked model. It was sold directly from Samsung, Best Buy, and other online electronics resellers. None of the four US carriers sold this model since they sold their own model. Because it is not carrier locked, there is very little bloatware. Now having said all that, the bootloader for the "U" version is absolutely locked by Samsung so it cannot be rooted or flashed at this point. That is everything I know at this point. Good luck. The product is reaching end of life, so you should pick one up soon if you want, but you can take it to any carrier in the US.

I opened the phone and it says on the motherboard SM-G935A which is AT&T but it is flashed with SM-G935U and its Sim locked. I will try to unlock it with a code from a third party :/

So you are asking about 935U software running on 935A hardware? That doesn't seem to be what the original post says. Everything I told you was about 935U hardware only. In reviewing your original post, it seems you are asking a hardware question. Nevertheless I wish you all the best with whatever device you have. Good luck.

If the motherboard says 935A, you have the AT&T version that was flashed with the unlocked U firmware. The U firmware can be flashed on any of the US carrier versions. Flashing the U firmware removes the carrier bloatware but it won't unlock the phone. If the phone was fully paid for and not blacklisted as lost or stolen, AT&T should unlock it, otherwise a 3rd party unlock service should be able to provided it's not blacklisted and you tell them it's a 935A, not a 935U.
Hi all. its probably T-MOBILE G935, then check out IMEIFIX.com, if not then Sprint G935P check out IMEIGURUS.

Version 5 Boot Loader G-390P S7 - Moving to Another Carrier

I have a question. If I bought this phone outright, and sprint basically locked rooting it via boot loader version 5+, could another carrier flash it with "something special" to get it on the carriers firmware? If I own this, and Sprint locked a feature on me, wouldn't that make them liable for damages?

Not really. You bought the phone to use specially on Sprint as a Sprint phone. When it came out, no one knew about the u firmware or using it on other carriers. There is a post on here about unlocking additional lte bands. If the phone is carrier unlocked, you will get some service on all carriers, but not all the bands will be unlocked.
