AT&T and Verizon will never allow their branded phones to be upgraded again - Android Software Development

I had an interesting conversion on AT&T's forum today. In short, I learned that both AT&T and Verizon had Samsung "hard code" their software to all their phones by altering the bootloader in version 5.1.1. This is nothing new to anyone who's tried to root their AT&T or Verizon Note Edge after the update. We know it as "branding", but in the past it was something we could usually bypass. No more. These "damaged" bootloaders will never allow these phones (and all future phones) to be rooted or upgraded EVER AGAIN. It's just not something a piece of software or an app can ever bypass. Even if you had AT&T unlock the SIM and you went to T-Mobile, you still have to live with AT&T's mountain of bloatware because the ROM can't be flashed. It like buying a PC and not being able to delete Windows Vista...ever. The horror.
What makes it worse is that doing a carrier unlock and jumping ship will get you no joy. I asked how someone gets OTA updates on a carrier unlocked phone and they said you can't. You can never update again. You'll need to go to Best Buy and have them flash updates for as long as you own the phone. How this doesn't violate the carrier unlock law is beyond me.
Google created an operating system that was supposed to be open source. We were happy to play the root game for years, but now AT&T and Verizon have changed the rules of the game and effectively put an end to the idea of open source. Now AT&T and Verizon androids are no better than iphones. If you ever want to root your Samsung devices in the future, DO NOT BUY YOUR PHONE FROM EITHER OF THESE CARRIERS!
This is a practice that they have already admitted will continue.

(Historically) Which are the preferred carriers to purchase from?

CDMA - Verizon (not), Sprint?, U.S. Cellular?
GSM - AT&T?, T-Mobile?
As with a lot of other people on this site, I'm wondering which carrier will be best to pre-order from? I use Verizon but HATE the fact that most of the times it's one of the last carriers to be able to root the phone. I would also hate for this to turn into another Verizon Samsung Note 4 issue. Too bad the rumors where Samsung was going to start making phones that were both CDMA & GSM/UTMS were not true (as far as I am aware of).
This way since I'm now paying outright for my phones (roughly $800 bucks for 7 Edge), I could use it if I moved between carriers. After reading some other posts, now I'm wondering If I'm paying full price (paid in full), Will it be unlocked? I can't be the only one that feels RIPPED OFF when I pay $800 for a device and can't have root = have my own admin access. Can you imagine buying a laptop and not being able to install/change your own OS? not having admin rights/root?
I feel it's a MAJOR excuse for a carrier to even say - if we give you root & you change the ROM, then it makes it more difficult to help you. Guess what?!? I have not ever asked for help and nor would I... Besides, why couldn't they ask for the ROM version your using... if it matches theirs, they assist... if it doesn't, they tell you before they can assist you, you must put their ROM back on? Yes - there will always be that one person... but hey - if they were able to gain root and swap the ROM, they should be able to swap it back or pay to have it swapped back. OR at least pay for insurance and "accidentally drop it" and have it replaced.
It really bites that I (along with so many other people) want to pre-order the phone for several reasons (the free VR and games along with getting the phone first) but don't want to be SCREWED by one specific carrier and not be able to unlock the phone, root and replace the ROM.
So after all that - which carrier (historically) is the best to purchase from?
CDMA - Verizon (not), Sprint?, U.S. Cellular?
GSM - AT&T?, T-Mobile?
Additional INFO - I'm also about to call Verizon to confirm - But I read 2-3 months ago that Verizon will now allow another carrier's phone on their network (if it is CDMA). If that's true, then why not purchase the phone thru Sprint or US Cellular if historically those phones have been rooted easier than Verizon? I've been on Verizon for so long, that I'm really not sure...
Comments? suggestions?
What I'm going to do is pre-order from eBay.
The phones have a hell of a mark-up (+$200/$300), but there are unlocked Qualcomms that are usually rooted much more quickly with better support for AOSP.
I hate paying that much, but I'm going to have this phone for years, and the hassle from carrier-branded phones just isn't worth it.
Edit: You should still be able to add insurance and such through your carrier too, depending on their policies.
Didn't have an issue insuring previous phones with AT&T even though they were bought off-plan through other retailers.
It is slightly cheaper when buying it from Best Buy, $779 vs $792. I saw the T-mobile version supports band 13 LTE, but I didn't see anything about CDMA support.
I also did follow up with Verizon about placing a phone on their network that was not purchased from Verizon. They said it is currently limited to 2 phones - I don't have the names because I didn't care much......they couldn't tell me the S7 would be added to the list. So does that mean people on Verizon are STUCK purchasing from Verizon?
For my s6 edge I much preferred the unlocked UK version over the US AT&T version. (Which is why I asked in another thread when we can expect to see unlocked international versions).
AT&T not only added crazy bloat but removed really cool features from the phone. Just took em right out. They also removed Samsung deals/bundles from the phone (there was a MS suite and a free TB of storage or something removed). And in exchange for screwing with the phone they had crazy delays on updates (because they had to re-remove and re-screw the phone).
Coming from iPhone I just can't deal with carrier customizations. Unlocked for life. (crazy that Apple is unlocked now and Android isn't -- bizarro world).

Nexus devices are the exception (6, 5X and 6P). The problem with VZW and Sprint is that they use proprietary CDMA technology for voice communication. You can bring just about any device to their networks and have data but you won't be able to make voice calls in most cases.

Tmobile period, not going to lock the boot loader you'll be able to root (provided the community finds a way, but it's a snap dragon and unlocked bootloader so they will most likely before it even releases. ) second if you don't want tmo service you can still root it and use am at&t sim so there's that.

Sign the United States petition to stop this at once: http://wh.gov/iGwh4
Thankfully, the firmwares are available (usually) quite quickly, and the drivers and tutorials are easily found so you can flash your own update with ease!
I understand your frustration, but thanks to XDA Devs all of this is manageable.
I agree about the open-source comment, btw.

S7 or something else?

Sad story finding out that the S7 is locked down harder than anything before. I'm still running a Note 3 that I purchased on release day, so needless to say, I've been holding out for the S7 since the S6 series didn't have SD card support.
Having had quite a few Samsung flagships over the years, I've really liked them, their speed and battery life, but having no root is a dealbreaker for me.
Things like TWRP (or MultiSystem), Cerberus, Greenify, TiBu and Xposed are essential to me. Seriously, without the ability to simply back up your current ROM or even just your apps and their data, what does everyone do when they get a new phone or some stupid update ruins what they had??
So that being said, I'm asking here if any of you are waiting it out for root before getting an S7 or if you're considering moving to another phone?
If you are thinking or have already moved to another phone, what's the best rootable phone of 2016 that has an SD card slot that is comparable to the S7?
I'm not hard to please, I just require root and an SD card slot - well, and a community of devs!
I heard there is an unlocked variant with CDMA, if not that then maybe wait it out until a root method is found.
Other options are the 5X, maybe the new G5 or the V10 if you want just root.

I'm so tired of people making this comment... The law passed last year clearly stated that no phone can be block from any U.S. Network if it's not stolen, not on an agreement, and has the proper radios to support the network... That's why they can't stop nexus devices, unlocked Motorola etc. Your phone will simply show up on Verizon site as "non Verizon device" and your stupid voicemail won't work. That's what google voice is for. That's why as soon as you pay for your phone, carriers have to unlock it if you request them to do so

Did you miss the piece where I said the phone has to have the proper radios? Most sprint phones do not have the appropriate radios which support Verizon CDMA channels, therefore the phone wouldn't work. Phones like Nexus, Motorola, and other unlocked phones typically have the hardware to support all U.S carriers.

Ok so this post is completely useless in this section then. There isn't an unlocked variant of the s7 that will work with Verizon nor has there ever been a galaxy phone from another carrier that would work. So stop being a know it all and take you condescending attitude somewhere else. What is your deal?

Once again you are diverting from my original comment, which verizon has nothing to do with if a phone can be used on verzion, or "white listed" as you put it. For your information there's been Samsung models that would work on Verizon from Sprint but they wouldn't get the correct lte signals...

First: I never used the words "white listed" anywhere in my posts.
Second: if they don't get the correct LTE signals then they basically don't work, lets not beat around the bush with here. Ultimately, I get what you are saying but it doesn't really matter. Other than to create an argument where there definitely doesn't need to be one your response really has no meaning in this particular thread. There are NO unlocked CDMA versions of this phone that will work on ANY other carrier and Verizon at the same time. /thread.
Can anyone tell me what an equivalent HTC, Motorola or LG phone would be that is rootable?
*Must be rootable
*Must have an SD card slot
*Hopefully has dev support for custom ROMs but isn't totally necessary since with root I can use Xposed to make it look like I want
I mean seriously, Samsung isn't the only top-tier manufacturer, why are we all addicted to this anyway? It's a great phone, I'm sure - but isn't there ANY good alternative in you guy's opinion?
I might just bite the bullet and get the S7 and hope for root, but the loss of Viper4Android would be a killer.
As a former flashaholic I have decided as long as I am on Verizon I will have to live without root especially when I got my sony z3v. I am glad I did. Flashing and setting everything up took up so much time atleast once a day at most once a week. And heaven forbid there was an issue and I would have to restore or start over. I then got a Verizon z2 tablet again without root on lollipop. This is a great phone and a worthy upgrade from my z3v. I think the line between needing and wanting features or gimmicks is getting blured.

Damnit, you're right and I know it, I'm just fighting it.
As a complete crackflasher since 2004, I've been around the block a few times - I suppose it's just habit to "require" root.
I think the hardest things about moving to a phone that has no root is no TiBU and no Viper. Seriously, how to people back up their data without TiBU? Of course I could manually back up all my apk's that didn't come from the Google Play Store, and I could manually back up all their \Android\Data folders, but that sucks. How is it in 2016 we have apps that require root and fewer and fewer phones that allow it?
Anyway, thank you for your perspective. I think I'll end up getting an S7 anyway and if it gains root someday it's a bonus!

Verizon Variant of HTC 10 or Unlocked Version With Radio Flash

Hi, I currently have an LG G3 that is over 2 years old and is unfortunately dying on me, so I'm planning on buying an HTC 10 in the next couple of days. My G3 is rooted and I've been enjoying the benefits of having root.
After doing some research, I've come to a cross-roads. I'm unsure of whether to get the Verizon variant of the HTC 10 or get an unlocked HTC 10.
I realize the obvious solution is "you obviously want root, get an unlocked phone, easily root it, and flash the Verizon radios". The problem is, I have no idea if, say a year from now, Verizon does something with their network so that the flashed radio on unlocked HTC 10's no longer works. Or somehow the flashed radio, in some way, becomes incompatible with Verizon's network (both very unlikely, maybe impossible, but that's why I'm asking). Perhaps the Verizon variant works on the network significantly better than the unlocked variant with a Verizon radio.
The other option is to get the Verizon variant. It will work as well as possible on Verizon's network. I won't ever have to worry about radio issues. But then I get Verizon's crapware and a locked bootloader and no rooting option except to mail it in to people I don't know (yes, I realize they can be completely trusted, and have been rooted and unlocking people's phones, but this is something I would really rather not do).
I think the safest option might be to get the Verizon variant and then wait for the exploit to be released so I can root and unlock the bootloader myself. The problem is, I have no idea how long this would take, and I need to go ahead and get this phone in the next few days.
What do you guys think? I'll probably end up getting the Verizon variant, but I love second opinions, especially by people who know way more about a topic than I do.
There is already a topic started on this exact same thing. A moderator will probably close this thread due to it being a duplicate. Please find the original thread and post your question on there.

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.

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

Im currently running G930U AQC1 (Android 6) firmware on G930V. Do I need to unlock bootloader in order to get the root access?

No, because you cannot unlock the bootloader.
Delgoth, how close are you?
