What up with carriers locking bootloaders? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Are us At&t custom ROM users going to have to move on to greener pastures with this Knox bs or will someone unlock the s4, note 3, and s5 (when it comes out) bootloaders at some point? Just curious if anyone has any insight on this, cause if we can't unlock it I'm definitely moving on to another carrier, personally. Or at least I'll buy international unlocked or Google editions in the future. Thanks and f at&t and Knox!

Bootloader being locked has nothing to do with KNOX. And AT&T has already released an official statement a while back that said they plan on locking ALL carrier branded phones in the future.

I understand that they are locked. Now can you actually answer my question on whether or not someone will figure out how to unlock it?

How would someone know that? There have been Bounty threads out for awhile and no luck. If they are still active you can follow them--

They lock them to keep people from hard bricking their devices. If it stinks...buy a Nexus or GPE device

I think we have to wait a while till the s4 becomes old news. Then att will care less about it and there will be less updates and more time for someone to find a crack or leak for the bootloader unlock and the carriers will care less

I think I'll just be done with at&t then probably. It's too bad that companies won't allow you to do whatever you want with YOUR phone. That's why I never got an iPhone! I actually don't mind running stock TW but I don't want to be stuck with it forever. Thanks everyone!

Sad part is until it's paid off it not really your phone. Since they have a warranty for a year to cover issues it only makes sense. Now if they would provide an unlock after that warranty is up and the contract is settled then it would make sense.

Att will never have a unlocked device again, watch and see.....

And these are the reasons I'm going to be moving over to T-Mobile or nexus devices. Just tired of AT&T all together.

Another view:
I will stay with ATT as Verizon is too expensive and TMO in my area has sh**ty reception. ATT has been perfect for me in that area.
Also, I have been a heavy flasher for almost 4 years. The phones now are powerful enough that flashing roms is not that important to me as it once was. If I can get root with Xposed/Gravity Box/3Minit I am good. Plus there are fairly good backup apps now that Nandroiding isn't that critical.
I don't see much more coming my way, after this year, in improvements I am interested in. Something like a Note4 or S5 would be as far as I care to go.
All IMHO of course
:good:

I thought that I read somewhere on a T-Mobile thread that the latest update locked the bootloader on the S4. Was that incorrect?

I'd go to the note 3 if I swapped to T-Mobile. I'm honestly tired of the s4 and the features don't wow me anymore plus the note 3 would be better in spec wise as well.

The i337 bl was always locked but the loki-doki exploit bypassed sig check and allowed us to flash recoveries and kernels. With mf3 they closed that loophole by "blowing the Q-Fuse", whatever that is. Googled it but forgot what I read.
And now you are limited to flashing mostly TW roms <4.4. No custom recoveries/kernels.

I'm not talking about a I337 from AT&T. I was talking about a T-Mobile M919 or do they use the exact same firmware?

Someone please set me straight.

I have an upgrade available and am considering moving from the One to the SGS 4.
I'm on AT&T. From what I've been reading,and I've been reading for a while now, if my SGS 4 comes with the latest firmware out of the box, I can root it, but Loki, therefore custom ROMS and recovery are out. Is this correct?
I was hoping to be able to put the Google edition ROM on the SGS 4.
Someone please set me straight.
Please and thanks
Correct, if it has the latest firmware than no flashing roms

The firmware version is on the side of the box, if I am not mistaken. I just got my S4 shipped directly from AT&T. It came with MDL.

If you want to install custom ROMs, yes.

Typically, at least from what ive seen, the ATT box will have an "Updated" sticker on it if the firmware has been updated. My GS3 had that.
I have both the One and the S4. I don't think I'd give up the one for the s4.

Just go to the store and ask the sales tech to find one that ends in MDL and NOT one that ends in MF3.
It sounds crazy or embarrassing, but it is not! Certainly it is not illegal or wrong to do this.
Others have done that and the AT&T folks really don't care, or if they do select another sales person or even another store (like Best Buy or even Costco and Radio Shack! Those other stores may even have better insurance plans than AT&Ts!)
(As to which phone. ...the HTC One is prettier, and it is unique in design, but would you be happy with less/slower ram, no changeable battery, no SD card, and a smaller screen? The S4 also has some very nice camera options that seem (to me at least) a bit better than the HTC One. Of course, it is all personal preference . . )
Good Luck!

Unlocking my ATT S4

I really want to sell my phone. I know I can get more money for it if us unlocked. Ive already googled how to unlock it and it seems pretty simple. My question is should I unlock it before its sold? Never unlocked a phone lol so sorry for this question.

I just got an ATT S4 I was planning to end my postpaid account with ATT and using prepaid.
I read in a forum somewhere that says you have a better chance of getting your non-iPhone device unlocked thru ATT international chat.
I tried numerous times with all my devices thru ATT unlocking to no avail. This time i tried the international chat just for the hell of it. Gave her my info and etc and what do know? It worked, she gave me instructions and the unlocked code. Another shocker is that this phone isn't even registered under my account.

You should have been around here during the loki days, then you could run any rom you want on your S4.

I asked the same Q in the forums "Android" and people heavily prefer the Nexus 5. I may sell my new S4. Get a Moto G then get the S5 but unlocking the S5 bootloader won't be any easier for awhile so I'm likely getting a Nexus 5 soon. My 2 cents.

You could always order an unlocked i337M (Canadian) online or something. Our S4s don't have locked bootloaders. (at least not yet..)
Kitkat on S4 SGH-i337
You can get the 4.4 kitkat on your phone by flashing the leaked version for the at&t S4. I have the same model phone and have flashed the leaked update so far no real big issues. I think if you were to wait another 3 weeks or so the official update will probably hit our phones in that time frame.:good:
Buy a kitkat bar, make sure its nice n warm.
Rub gently all over the device.
Now its a kitkat device
Or you can flash it and end up with a device on kitkat with a locked bootloader or bricked if you're on safestrap

[Q] S4 with stock firmware UCAMDL

I have a Galaxy S4 in flawless condition with the original firmware UCAMDL. Its rooted and has nottachXposed installed and working. I haven't been in the modding scene in a while since I first got my S4 and I'm looking to get the Galaxy S5 and I'm not sure what I should do with this phone, any ideas?
I would sell it and use the proceeds for the s5. Now you never upgraded past MDL, correct? If so it means your device has more options becuase the buyer can loki, and use more roms than those who upgraded and have to run Safestrap roms.
That could get you a few extra bucks.

Yea I never upgraded past MDL, I was thinking of selling it also just need to find a buyer who can put the device to good use . I don't think I can be specific on swappa about all this, I actually want to find a buyer who knows what their talking about.

Unlockable Bootloader?

In a conversation with a verizon salesman he told me this http://imgur.com/WlmNyl3
he probably doesn't know what you mean. he probably means like global unlocked.
the past few samsung devices have locked bootloaders, and verizon doesn't go around that. that, plus KNOX means the GS5 WILL have a locked bootloader, and we'll have to do some loki stuff to get around it like with the GS4/Note 3 etc
Knox has nothing to do with a locked bootloader.

That is also a Nexus phone.
The catch being Samsung and Verizon want enterprise adoption of the device, so like the S4, it will very likely be locked by same design.
No such concern with the Nexus.

That's not the point Knox is used for those secure businesses. It any way does it mean with having Knox means the bootloader is gna be locked. A bootloader can be unlocked with Knox still present but there is the Knox warranty that you would want to avoid of course.

I appreciate you sharing, but answers from a Verizon sales rep are about as meaningful as those from rolling a magic 8 ball. They very rarely have even the slightest clue as to what you are talking about. Actually since you have made the effort to visit this forum, chances are you already know more than they do.
I fully expect the VZ bootloader to come locked up tight. Hopefully we can get it unlocked as fast as the M8 did. I could care less about Knox or my warranty.

Hoping and wishing ain't going to make it happen - look no further than the VZN S4 / Note 3. If not for the loki exploit on the initial S4 release, AOSP Roms would be unavailable. Check out the Original Android Development section on the VZN Note 3.....that is most likely the future of the S5. Be happy with TW or get a Dev Edition - probably your only options.
