[Q] AT&T S4... Switch to T-mobile S4

I Have the AT&T S4... should I switch to T-mobile S4? (bootloader issues)... I want to make the move before I can no longer return my AT&T S4... any thoughts? I know the AT&T S4 would tend to have more going on in terms of roms and development, but even well known devs are saying stay away from this version... seems like they dont think it's gonna happen soon at all.

From what I read on the T-Mobile forums they are still trying to figure out if the bootloader is locked like ours

right there with you, i've got 13 more days to return-no-questions-asked, just a little butt-hurt i already traded my lovely GS2 in :crying: should have kept that little sucker around until all this washed over. I would go over to HTC One, as it is developer-friendly, but i just can't bring myself to a non-reparable design as these USB ports at the bottom go after time, no swapable batt, and missing micro SD card (love having my pics there in case phone dies, while it's not the ultimate in security, it's at least a small form of backup). Also, the added screen real estate i think is the perfect phone size.
Really hoping the TMob version can be SIM swapped, might not make it to my return date to get confirmation on this....boo

I am thinking of going HTC one. Cant afford to wait a year for potential screw up where Samsung releases an unlock. There will be no unlock for boot loader u less Samsung or somebody working there leaks it.

This site claims to have the unlocked US T-Mobile S4 available for pre-order. I have no experience with them, but they are mentioned several times in the S4 forums.

Nice, thanks! My concern is that they are probably talking about sim unlock which is possible on At&T already, I wish we had someone who owns a t-mobile S4 and can confirm an unlocked or unlockable bootloader.
EDIT: Looks like according to the t-mobile forum theirs is unlocked bootloader. Im hoping we can just get the bootloader unlocked by then but if not.. plan B!

Wasn't your original question about where to buy a T-Mobile S4 without having a T-Mobile line? If so, that site claims to have them. If you are planning on using the T-Mobile S4 on AT&T networks it will need to be sim unlocked. Otherwise, I'm not sure why you are looking to buy a T-Mobile S4 without having a T-Mobile line. As far as the bootloader goes, AT&T is locked, T-Mobile is not, but that has nothing to do with a T-Mobile phone on an AT&T line? Maybe I am just not understanding what you are looking for?

Snapdragon is locked?

Many variants are available with Snapdragon CPU and I want to ask that whether each of them is with locked bootloader or not?

The Snapdragon variants have locked bootloader.

Are you sure about that? T-Mobile has not locked the bootloader of any recent Samsung device that I know of. I'd be surprised if the G935T was locked.

Ok, I'm surprised.

It's quite ironic, the Snapdragon variants would have been the most fun to root and ROM, allowing for both TW and AOSP type custom ROMs. But they locked the SD820 variants down with secure signature verification stuff... So lame.

I wouldn't be surprised if all the snapdragon variants were bootloader locked since they are all tied to carriers all of of which aside from T-Mobile and Sprint (which are probably locked too now) have a history of locking bootloaders. I am not only talking about the U.S. Look at the Japanese market, NTT DoCoMo has been locking down it's phones forever.

Is the locking of bootloader new? Is it like the newimpenetrable Denuvo DRM?, both put it against piracy and customizing software?

Holy crap, a T-Mobile Samsung Galaxy phone has a locked bootloader !!!! Unbelievable. Never thought I'd see the day. How did this even happen ? Did T-Mobile give in ?
I was waiting for root on the S7 Edge, before buying it, guess I'm not getting this phone now. And then what does this mean for the Note 6 ? Same BS locked down ?
Guess I might sell my Note 5 now for the Nexus 6P.

You could always get the International version, which isn't bootloader locked.

I'
My Wife and I are on JoD with T-Mobile, we both signed up on T-Mobile last Summer when the Note 5 launched. I went to Tmo for the development community and custom ROM's the Note 5 would have, and it did, and I've been a happy camper here.
But...
If this is the new trend, the S7 Edge being locked means no "Jumping" onto this phone now, and maybe the Note 6 will also be in this horrible situation too. Leaves me questioning even sticking with T-Mobile now, as the other phones I like are the Nexus phones.
My question is, since T-Mobile isn't really a contract carrier anymore, how can I get out of it ? Our two Note 5's were on the JoD program, can we just return these N5's into T-Mobile, and cancel the service and be clean and free done ? Or would there be some payment needed ? Or if maybe stick with T-Mobile, but still get the Nexus 6P and not be on JoD anymore, how much does that save not having two phones on JoD anymore ?

There should be only one variant capable for everything (I mean for custom ROMs and MODs by default), only one variant everywhere in the world and on every carrier. But I know this is just a dream.

Unlock bootloader us snapdragon galaxy s7?

So here is the deal. All of the variants for the Galaxy S7 / S7 Edge now have unlocked bootloaders except the ones from the US, even the chinese qualcomm variants got unlocked bootloaders. The way they got the unlocked bootloader was through an unlock tool provided by samsung on the galaxy app store. My question of the day is...
Is this possible on the US variant?
Could a modified version of this app or straight up this app be used on the US variant?
My hope is that I can unlock the bootloader of my Verizon Galaxy S7 now that I have lived with this locked bootloader root for 8 months now, and possibly have it run the nougat firmware, rooted, and have TWRP.

It's not Samsung, it's the US carriers who insist on the locked bootloaders. Your next question is probably going to be, "Why doesn't Samsung stand up to the carriers and insist their bootloaders be unlocked?" The answer is simple. Samsung is in the business of selling phones. They're not going to stay in business very long if they make that stand, and two of the largest carriers with the most customers (Verizon and AT&T) say, "Fine, we won't carry your phones then." The people who root their phones and care whether or not their bootloaders are unlocked are such a minute fraction of the total wireless carrier customer base, so the carriers stance on the bootloaders is not likely to change.

Verizon and att kinda has Samsung by the balls they could go on without sammi
now sprint and tmob need Samsung plus all the little companys need Samsung now like lg
all the carriers have lg by the balls if u don't make the software how we want we wont sell ure ****.
Samsung could survive without the us carriers it would hurt em but they could survive
now lg on the other hand could not theyre mobile phones division would go down if it wasn't for the us carriers this has all been gone over in of the lg threads on the same thing no bl unlock

Now out of curiosity are these bootloaders locked or are they signed with a key???
If a key what kind of encryption is used?
I know the g4 is encrypted with a 256 bit key which is basicly unhackable at this point in time.

Locked, tighter than Apple too! Maybe we will see an exploit one day, look a t the Note 4 which took a year, or was it longer?, and then look at the s4 and the others, ONE exploitable bootloader then its locked down. It doesn't affect me too much personally, getting Pixel when taxes come in, but would like to see it in the future since my S7 will be my go to backup.

cant we try flashing that firmware version to our phones and use the app?

This is why my next phone will either not be a Galaxy S7, or will be the international one. I'm eyeing the Pixel 2 for my next phone though. I didn't want the Pixel because of the lack of water resistance.

Have not found a "place where this is being worked on" per-say, but please let it be known to any developers working on a method of unlocking the US S7/S7 Edge - I purchased an S7 Edge (T-Mobile) and shortly later ended up aquiring a S7 G930U - My understanding is that even though it's "U" It is only unlocked to use any carrier/sim, but still locked bootloader - which I would say seems true as it complained after the "soft-root" and me then enabling to many 'rooted' apps - causing a lockdown and no way around it but to re-flash.
** The reason for posting this ** - I am more than willing to 'test' any possible methods on the G930U that I have. I'm not a skilled android dev. but neither am I a novice, I am quite capable of providing any needed data, and also have quite a bit of software that could possibly help in finding answers, DFS and others. I also am very good at acquiring software, If there is anything I can do to help with this please get in touch with me!
Dycast - coming from my beloved rooted S4 as a crazed flash-a-holic - now with lovely S7's LOCKED to the hilt and hating it.. Like I just had a leash and muzzle strapped on.. If it wasn't for being able to play with the VR end of things I would just as well go back to my S4..

No unfortunately not. THe chinese phone uses a special keycheck that the US variants don't have.
So when you use the app it sends a packet request for a non-existent key.
there was a whole thread about this and the guy tried to reverse engineer it and it wouldn't work
Silkmeister

The reason why what works for the international variants of the s7 won't work for the United States ones is because the US ones use the qualcomm snapdragon. Two different processors. Also it is both the carriers and samsun who have a say in locking the bootloader. Samsung makes the devices it is their choice how they make it. Verizon and att models of samsung phones have always had locked bootloaders. Tmobile and sprint in the past have not. People were shocked the tmobile s7 had a locked bootloader. Even tmobile said it should not have been locked according to them. You never see unlocked bootloaders for iphones on any carrier because apple juat doesn't do it and also their software isn't open source like android is. The s8 is going to have a locked bootloader as well from what I have read. I am hoping tmobile goes back to their roots heh pun intended. So that we can get an unlocked bootloader for samsung phones again.

The question still remains, what makes it as locked as it is at this point? Is it because Qualcomm wrote the the original closed source code for Android's "aboot"? Or is it something that is more obvious?

Everything points to them just being signed now. So we cant flash anything thats not signed with lgs or in this case sammys key

At this point it's been over a year now and still no unlocked bootloader. I'm dying without any custom ROMs like lineage is. I just love playing with my device. Can't they just let me do that.

Realistically that shouldn't be hard to discover either. We know where to look for their encrypted key. In the footer of the .Tar files, and the last few bytes of the partition images. Now the question is, how we use DD to strip off all but like the last 2048 bytes of the boot.img's, to compare amongst the different incremental builds for the same device.
That should give us all the different keys generated from Samsung's private signing key. This gives us a method to reverse engineer the algorithm used to create the public keys from the private key. This in turn will then lead us to either A.) Reverse Engineer the actual private key, or B.) Give us an equation with which to generate our own key which the Device will accept.
Using @droidvoider 's Dirty cow based root console, we can pull the .pem files from the stock firmware, and also pull the other firmware specific certificates. Using his console along with combination firmware also allows us to mount the /system & /data partitions as RW in an environment which does not care about DM-Verity success. That gives us a route for installing a system-Ish root that can persist through a reboot without an eng kernel.
But if the signing keys are the last roadblock, I think the greyhat root project is almost done with that thanks to a the other member(s).
We will see soon.

Canadian Variant Root

Plausible? I ask because I see a lot of American variant threads ETA's quite high due to a locked bootloader. Would we get these problems as well up there in the North?

Yes we're just as fcuked.

Last year Canada got Exynos variant with bootloader unlock, but this year Canadians are getting Snapdragon. Plus, rumors are maybe even the Exynos variants do not have bootloader unlock this year. We are waiting to see.

Because Canada is basically U.S. 51st state. Except for the French parts. You can keep those.

The reason is your carriers control the market and they don't want you to do whatever you want with your phone, that kind of thing cuts into profits. You share this with your friends in the US who also suffer carrier control of the market. Oligopolies are good for billionaires, not so much for consumers.

Give it 3-6 months and I'm sure we will get root like the US spec S7 did with the engineering bootloader. That said, if you search you can still do a lot of stuff you thought you needed root for. I haven't had a rooted device since my S6 and the only thing I really miss is Viper4Android, and Adaway. And this is coming from someone that would flash new roms multiple times a day. Trust me it is hard, but I kind of like the challenge to find workarounds without root. I guess I'm weird like that.

We in the U.S. already have some French:
https://en.m.wikipedia.org/wiki/Louisiana_French
But they didn't try to split the country in half, like in Canada. Nor did they demand bilingual signage...
Besides it was a joke reference.
More likely the shared Snapdragon chipset is for possible roaming ability on Verizon or Sprint networks for Canadians who cross the border for vacation or business reasons. Snapdragon has the CDMA bands, while Exynos does not. I haven't researched it, but surely some of the Canadian carriers have roaming agreements with U.S. carriers? Including probably Verizon and Sprint.

I honestly thought this guy was going to Mexico to pursue his career by becoming a movie star.

Hi,
An update from unlockunit.com:
Hi Hackerjj,
Unfortunately, if you cannot find your Phone Model, Country or Network listed on our website, we are unable to generate the unlocking codes for your device.
If you get the message ‘’Unavailable’’ after entering the order details on our website, one of the below situations may occur:
1. Your phone is locked within a CDMA and not a GSM network (you can check on www.gsmarena.com if your phone is a CDMA model)
2. Your phone is not part of the networks/countries that we currently unlock
In order to receive the correct unlock code, it’s very important that you select the correct country and network you originally bought your phone from. In case you place an order with the incorrect order details, we will not be able to refund your payment.
We are constantly improving our service and we hope that very soon we will start to offer unlocking codes for devices locked to Verizon, U.S.A. such as yours.
Thank you for your collaboration and we apologize we couldn't help you this time.
Have a great day!
Kind regards,
Ionut Z.

Do you think following this guide, (in case that is compatible with the G9750U could works to unlock?

I don't believe it would change your IMEI.

It needs an active Verizon sim in it for 24 to 48 hours before it will umlock. Once unlocked it should receive a message saying so.

Thanks! - I do not have any Verizon chip, probably I can buy one from eBay, but one thing is that probably does not be activated due I am right now on Mexico. Thanks again!

not true.. i never understood why people will come in here and trust anything anyone says when it comes to sim unlocking lol..
verizon unlock policy states to prevent theft/fraud users are required to activate the device with verizon then after 60 days the device will be unlocked..
if his verizon purchased g975u was never activated on verizon then he hasnt even started his 60 day wait period.. verizon specifically implemented this policy because of people doing what the op is doing... purchase a phone for cheap somehow then use it on some other carrier/network without ever using verizon..
i am sure they had lots of theft and fraud going on with users scamming vzw devices for cheap then reselling for profit since they were unlocked theyd work anywhere out thebox so thisis their way of trying to combat that..

Thanks! I had bought a Verizon Sim, it is on the way, I think I will receive it in 2 weeks, after that we will know it the cellphone is unlockable. This is the last thing I can do, I think this cellphone is un-rootable also a pain. Another way is to use this provider, but I have not completely trust and is very expensive. https://store.unlockboot.com/remote-unlock-service/
