T-Mobile S4 - Bootloader Locked or Unlocked? - T-Mobile Samsung Galaxy S 4

I'm on T-Mobile's website ready to order the S4 but I just want to know before I do if anyone knows for sure whether T-Mobile will lock the bootloader like AT&T.
Thanks!

Check post #3, he says his is unlocked using the motochopper.

Obtaining root is not related to the bootloader in any way.

According to this article - http://www.xda-developers.com/android/official-and-confirmed-att-galaxy-s-4-is-bootloader-locked/ - start of paragraph 3 - it's unlocked.
Still waiting for confirmation.

My bad. When I posted I read somewhere its locked lol

Most likely that may have been in one of my posts.. at the time AT&T _did_ have a verifiable bootloader (I wouldn't call it locked, per se; it just checks the boot and recovery images to make sure it's AT&T approved and is good on their network. and if AT&T images aren't used (or otherwise fooled), it'll result in a brick).
and that's awesome that the motochopper can be used to unlock bootloaders now.. motorola xoom (IIRC) all over again...

Motochopper is a root exploit. It does not unlock bootloaders.

Can anyone confirm this 100% one way or the other?

[Q] How do I unlock my phone on 4.3? Is there a rom I can install to unlock it?

I have seen a number of the more experienced forum members answer this by saying that once you are on 4.3 with the official MJB bootloader you will need to use one of the pay services to sim unlock your phone.

You can request the unlock code via this URL ...https://www.att.com/deviceunlock/client/en_US/
I haven't had any luck with them though using this request form as each time I've tried it's been with a phone I purchased from the secondary market and then they reply that the details on record don't match mine. Congress recently approved a bill making it legal to unlock your phone and I understand the new bill also includes a provision allowing third-parties who obtain the phone legally to request the unlock code. So perhaps things will be easier for everyone when the new bill becomes law and takes full effect.

I hope AT&T is cooperative. I am still able to go back to 4.1.1 on my SGS3 to unlock, but I never unlocked my Captivate - which is still functional. I keep it as a backup. It would be nice to have it unlocked.

How were you able to go back to 4.1.1? Right now im on 4.3 and people are saying not to downgrade or it'll brick your phone. All I wanna do is go back to 4.1.1 to unlock my phone and upgrade to 4.3.

I will be able to go back to 4.1.1 because I am still on 4.1.2. I never allowed my phone to take the 4.3 update.

Been perusing them for a bit. Not having much luck implementing for the moment. I think that is because I didn't have a sim in the phone. It's not a big issue to me at the moment. As a backup phone I don't actually need to unlock if I go with AT&T or even if I switch it to Straight Talk. Of course, it would need to be unlocked to use other prepaid options. Anyway, I subscribed to the threads I will revisit when necessary.

You will never be able to unlock the bootloader on that phone, unless your carrier can give you some kind of code to change your unlock status (not sure this is even possible).

The BL is different, if it came from O2 then chances are you cant unlock the BL.
So there is no chance? It worked with xperia arc and omnius. Costs about 15$, that would be ok. But will it work with our z1c in the near future? Or is it just "luck" to find an exploit?

Well nothing is impossible, but it isn't likely as it requires a bootloader exploit. Realistically it isn't going to happen though, unless some smart people devote a lot of time to it. The most likely scenario (using test point to gain more software access) would require hardware tampering.
Hello Mentalghost,
Unfortunately there is no way to unlock the bootloader when the status is "No".
Have a great day, cheers!

MentalGhost, where did you purchase your phone? This phone isn't sold by any carriers in the USA, to the best of my knowledge, so the bootloader shouldn't be locked.

Bought in UK where I am not in USA. Might take back to shop where bought from and see if got any others in lol
Or wait for locked bootloader versions or someone makes modded version with unlocked rom that is been modded like one where you install modded that is unlocked install and then can unlock bootloader did in xperia s I use to have was a modded rom that was originally saying bootloader unlock no and added new Base rom and then said bootloadr unlock yes maybe this will happen on this phone in time or locked bootloader kernels and rom come along

I'd recommend to anyone that is still able to return a Phone to do so because I think you'll find you'll be waiting a long time for a solution.

Plus, there will be no solution. The reason why Xperia Arc S and other 2011 Xperias worked with testpoint method was because of that there was a big security flaw in the security of the testpoints nand access, but those flaws have been fixed in newer Xperias and newer 2011 Xperias also.

+1 It was coming to that realization that I sold my O2 locked Z after 6 months to buy an unbranded Z1 Compact. It worked out cheaper too spending hundreds of pounds up front for my Phone with the added bonus of having access to all of it.
What happens if you still follow the instructions on how to do it? I didn't check if it was allowed and I'm stuck in bootloop and I can't flash via flashtool,

[Q] How to unlock the bootloader?

I'm getting my T-MO G3 returned soon and would like to unlock the bootloader asap but I'm not exactly sure how. Is it just FASTBOOT OEM UNLOCK or is there something else?

Whenever I've unlocked a bootloader, it wipes the device. I'd rather do that before I set it up with my apps and accounts.

Correct me if I am wrong but every phone comes with a locked bootloader even the nexus line you need to unlock. We really need to stop calling encrypted bootloaders locked. So this phone isn't encrypted but surely it is locked.
Our G3 is the only one that's unlocked.

Guys. There is a difference between unlocked and unlockable. This being unlocked means there's nothing really to do. That's why it's so unusual.

I read somewhere on google that the T-Mobile version was going to come factory unlocked. Can anyone comment?
When where ? Can you add the link

The bootloader is unlocked on T-Mobile
I find it odd that the key was already turned. Normally they have the door locked but give you the key to use if you so choose. Honestly the way this phone came out without any kind of safety for the boot partitions is asking for a malicious app/virus to brick phones. Unless purple Drake did the factory unlock but I don't think they stated that.

No they stated that when they were exploring root and unlock methods they were surprised to find out that the Tmo version was already unlocked... I would think that raises the chances that LG releases a key to unlock other variants as well? ... other than at&t and Verizon that is...

Yeah and you know this might sound silly but I wonder if anyone has tried the normal unlock commands in fastboot for the other phones. Development isn't booming like on samsung or htc phones so you never know. Pretty sure somebody out there has tried I mean somebody had to right? Maybe Ill try to lock my bootloader in fastboot and see what happens. I would like to have it locked when I'm not modding that's just good practice.
*Edit
locked bootloaders and encrypted bootloaders are different just wanted to make sure everyone reading this that didn't know that now knows.
As always people keep getting confused between sim unlock and bootloader unlock.

Can confirm. Got T-mo G3 with out knowing. Feels like I won the lotto.
The D851 variant ships with an unlocked bootloader, but SIM-locked to T-Mobile. Just to make it 100% clear.

I was able to sim unlock my G3 for like $3...there are several posts in the forums with similar success stories.
I used unlockcode247 and it worked like a charm. I got the code in under 15 minutes. $2. Can't go wrong.

Verizon version - no OEM unlock ?

The flag does not exist at all in developer options.
Does this mean verizon version bootloader is not unlockable? (Locked down)

Thanks! I found something similar last night on a different site and it didn't seem to work. Later I will try factory reset + this procedure.
I know Verizon locks down the bootloader on the Pixels they sell... Hopefully not the same with their tablets!
Sorry to break it to you but the Verizon Galaxy Tab S4 has a locked bootloader that can't be unlocked. Pretty much any device you get on Verizon, you can expect to be locked down.
