[Q] What GS3s DON'T have a locked bootloader?

Hi...Restoring a GS3 for use as a PDA (right now), and found one that is worth the trouble to fix, which happened to be on Verizon with the Knox bootloader (running 4.3 OTA, ML1).
I have several other android devices, and am partial to AOSP ROM versions.
Just want to know which carriers haven't installed this stupid, ugly, no opt-out knox junk (I mean, this may allow my company to give us the option of using these devices for work, but to not allow the option to secure/unsecure is a G_d given right, IMO). Researching so far, it seems as if the Sprint version doesn't have it, but if anyone knows off the top of their heads before I start rummaging through the respective forums, please do let me know. It can be any carrier (think I want to stay with the snapdragon, though, which rules out the international version).
This forum was easy to find the info regarding this locked bootloader, and for that I am grateful.
Any help/pointers appreciated...there is no "generic" Galaxy S3 forum, so I'd figure I'd ask here.

Sprint and T-Mobile have unlocked bootloader. And just for your information, it is not Knox that is limiting your unrestrained access to your phone. It is the locked bootloader courtesy of Verizon and AT&T. The Sprint and T-Mobile versions also have Knox, but the bootloader is not locked. Knox is simply a flag that trips and indicates your phone has been altered.

Thanks for the info, and the explanation of Knox.

The unlocking of insanity (mha l-29 attempting to connect to verizon in the us)

I have gone through thedepths of the interwebs and have not been able to find one process that has successfully worked. I am currently trying to get my sexy, brand new Huawei mate 9 connected to Verizon in the US. Now, before you start railing me about its not possible and blah blah, IT IS.
My thought process behind the steps that I would need to take are;
- Gain an unlock code for the boatloader ( tried multiple ways, no dice )
- Root said device
- Change IMEI number to one that is compatible with Verizon
Any direction would help, thank you very much!

You can ask for bootloader unlock code to huawei, three weeks after you buy and register your the phone.
There is not way to root the mate 9 yet.
Change the Imei is not legal in my country, but I think you will need additional external hardware
Best luck in your attempt.
Enviado desde mi MHA-L29

Folks always say register the phone.. I've tried.. But I get stuck when they ask for a Chinese number...

You're the first person I've seen mention this. The phones should not be carrier locked? Also, this phone does not support CDMA currently, so Verizon will not work on it anyway - maybe that is your problem? You can also download the Huawei Bootloader Unlock app in the Google Play Store. They will charge you $7 for a code, but it works.

You don't need to do anything with the IMEI for Verizon, as they don't work on a whitelist system, nor do you need to root. However, you'll only have LTE since this phone does not support the correct CDMA frequencies for voice/lower tier data services on Verizon. (Obvious exception to voice being if you can get VOLTE working.)

I have the Chinese model which is supposed to support CDMA (albeit only on a Chinese carrier) and I wasn't successful connecting to either Verizon on the US, or KDDI in Japan (on CDMA of course), so I'm pretty sure it's not going to be easy to get it working, if it's even possible at all.
Furthermore, no way to change the IMEI yet, that I know of. Not allowed to discuss on XDA, though, I think.

I did also tried with Huawei Support with no luck. At the end I get my code from this app with small price: https://play.google.com/store/apps/details?id=unlock.boot.huawei&hl=en
For rooting see post: http://forum.xda-developers.com/mate-9/development/recovery-unofficial-twrp-huawei-mate-9-t3515617

Thanks for all the input everyone! I am following the latest response on here and so far I have gotten the unlock within an hour and a half and waiting until I get home to began unlocking and rooting! :laugh:

Samsung J7 (2018) J737V

Hello all! I am an owner of a Samsung Galaxy J7. It is the newer generation, model J737.
I did not see any threads on this type of phone and so I wanted to get things going.
Anybody know of roots being developed for this? Or is this model compatible with the same root software as its predecessors? What shall we do!? I am no phone programmer but I am willing help out with what I can! Share what you know.
Thanks.

J737
I'm still looking for all the firmware. I have the Verizon model. Firmware is listed as: J737VVRU2ARI4.

MOD EDIT: PAY-PER-CLICK LINK REMOVED
https://androidfilehost.com/?fid=1322778262904010272 - J737VPPVRU1ARG1 / Prepaid / July 2018 security patch (1)

I just recently purchased this phone as well and am looking to root, install twrp, play with rooms etc. Injave found very little info on this model. Its surprising to me that with all the great mid range phones available now still so much attention is directed toward company flagship models. I started rooting phones way back with my S3, then two LG G2s, S4, and S5. Since I have mostly purchased midrange phones because the pre-paid plans are significantly cheaper then contract phones and just as good as they use all the same networks. I guess the main draw back is the majority of devices associated with the pre-paid networks have locked boooaders that cannot be in blocked until after a year of service. The exception is the verizon pre-paid devices which only require only the first month of service to be purchased before becoming eligible to be unlocked. They will then happily provide you with an unlock code. I'll just go ahead see what I can accomplish with my j737 by using files for other j7 devices and see what I can accomplish. Some might find this foolish but I love this stuff and patience may be a virtue but i e never been good at waiting. If I have any success I'll post back....
.if I don't post back it's because I'm using my j7 as a paperweight.

Network/Carrier Unlocking Iphones and Androids

Hi Guys! I'm kinda new to the forum. I made an account a while ago, but I never really used it... until now.
Let me just say that you guys helped me out more than once before, but now I need to ask questions to which I haven't been able to get a direct answer to. I dabbled in phone repair (mainly just rooted a few androids). I'm still a novice, but I'd like to start getting work experience. I'd like to start my own business unlocking, repairing, and eventually, creating custom ROMS for all phone models. But I'm still not 100% clear on a few things.
Is it at all possible to unlock android phones by flashing an international ROM? For example, let's say I have an Samsung Gakaxy S7, model SM- G930V (Locked to Verizon), could I, in any way, flash a 930F ROM (oran international variant of the 930F) onto that phone to unlock it? If not, what methods are available to me? Besides the obvious "contact your carrier and have them do it". There are a few sites such as
unlockauthority
unlockradar
That claim to be able to unlock your phone, but how do they do it? Are these sites even legit? I've heard of a few programs, such as Chimera Tools, that claim to be able to do the same thing, but the questions remain the same: are they legit, and if so, how to they do it? Can I learn to do it myself? If so, how? If not, why?
The same applies to iPhones, which I hear require iCloud to unlock. If I have an iPhone X, locked to AT&T or T-Mobile, can I just log in to iCloud and unlock it from there in just a few clicks for free?
watch?v=LsEJwX7BVcc
This guy claims to be able to unlock "any" iPhone by just inputting a few codes. I question the legitimacy of this, of course, but I don't have access to a locked iPhone to verify.
Again, I'd like to start a business. Most people are looking to unlock their phones, so that would be my focus.
If anyone can help me, if even a little, I'd be very grateful.
And of course, once I learn more about mobile devices, I'll be able to help you

Generally speaking, you can't use firmware from one model on a different model, especially when it comes to any kind of Verizon device, that leads to a bricked device. There are cases where you can flash a firmware from a different model number, but those are rare cases and the devices are virtually identical hardware/software(bootloader).
If you're trying to unlock bootloader on any kind of Verizon Samsung device with 4.4 Kiit Kat or newer android, you can give up on that idea, you'll never make it happen, many, many, many people have tried, there is no way to do it. Verizon/Samsung has that locked down tight.
When it comes to unlocking phones, there is no general way of doing so. That is case by case and model number by model number. Not all phones can be unlocked and the ones that can be unlocked use different methods. You'll have to find the method for each specific model number.
We can't help in the iPhone department, this is an android development site, it doesn't deal with iPhone at all, not in any shape, form or fashion. You'll have to go somewhere else with that.

Thank you very much for your input! I'd like to keep this thread open, in case anyone else has something to share.
I really appreciate your help. From what I understand, unlocking Androids can only "safely" be done by contacting the appropriate carrier, or finding a specific method for each phone model.

I'd like to talk here if you don't mind. Private message me if you want to speak privately.

Can I root my Samsung S7 and gert rid of "all things ATT"..?

So, I'll apologize if this has already been dealt with previously, but I just need to verify what I've been told by a friend who knows Android systems (and Samsung S7 phones) a LOT more than I will ever attempt to understand..
About a year ago, I bought a Samsung Galaxy S7 from a 'rebuilder' (my term) who mentioned at the time "... it was ATT phone..", and, yes, when I turn it on it does the ATT circle jerk logo and has an ATT logo on the back of the phone. This was of no real concern to me, because my service purveyor uses the ATT system (Consumer Cellular), so it's worked well enough. But unfortunately, it also has a boatload of 'semi-proprietary' ATT trash in the phone which I'd like to get rid of. To confuse the matter even more, it appears that I cannot 'unlock' the phone because it has not been associated with an actual active ATT account for close to two years, and it APPEARS that now they refuse to accommodate an unlock code for this phone.
So... according to my friend (Mr. Android Phone), I can 'root' this phone to 'factory original firmware' and make it (in essence) just a plain-old-vanilla Samsung S7 without this rather bogus ATT firmware and the myriad of craplets I'd like to get rid of..
So, I'm here looking for "expertise" in such things because I certainly don't want to 'brick' this pretty nice phone, but I also want to get this to a point where there is no association with ATT in any manner. So my question sorta comes down to: "can I root this and be rid of all things ATT?", and "will this allow me to achieve an 'unlock' without having to play ATT's games? (I had QUITE the discussion with an ATT 'support' dude a couple of hours ago when he flatly refused to give me an unlock code so I could simply ATTEMPT to see if Consumer Cellular's T-Mobile service might work better at my home, since CC tells me I'm right in the center of a brand new rebuilt 4G service area).
Does any of this make any sense to anyone? Pardon my ignorance, but if the IMEI # is somehow 'tethered' to ATT and they won't "release" it, how does rooting help with this? - or is this something more like an 'association' of the IMEI # AND the ATT firmware...? GAH!! I'd just like to be totally rid of all this ATT junk and have the freedom to choose whichever service I want.

Hi There that's a lot of words partner! I'll try make the answer easy to understand and I've cut out much of the post so my reply isn't huge.
1. Yes you can install vanilla firmware which will remove all branding from AT&T and you don't need to root the phone to do this. here is the firmware for your device >>here<< You can also use XAS or XAA. You will see the guide and the Odin you need to flash this firmware.
2. This is another version of Odin on this website if you have any issues with the one on Sammobile. >>here<<
3. Unfortunately you cannot unlock the phone unless the original cell phone provider gives you their half of the unlock key as a code to input to the phone. In the UK once a phone is out of the initial contract period it is illegal for the provider to refuse to give you this code whether your still with them or not. I know in the USA you guys gets ****ed over. The original account holder of the phone can ask for the unlock code but not you.
4. Changing the firmware and unlocking the phone to any network are two different things, flashing unbranded firmware will not unlock the phone the network is tied to. They don't make it that easy!
5. As far as i know T Mobile (USA) has also moved to G930U firmware so you could be lucky with a T Mobile SIM working once the phone is flashed with this firmware but don't hold your breath. Check Sammobile for the T Mobile firmware too.
6. IMEI number is tied to the phone so in theory it can be changed after the phone is rooted and you are able to modify the EFS partition but it is extremely difficult even for veterans like me and it causes lots of problems with cell network registration. Leave well alone if you don't want a completely useless device.
Things to make flashing go easier
1. Turn off FRP lock or sign out of the Google account on the phone or delete it before you do anything, you can put that account back on the phone after flashing.
2. If you enable Developer options make sure " usb debugging" is enabled and OEM unlock, not essential but can help when things go wrong.
3. Anything you want to keep, pics media etc back up or move to SD card, the SD card won't be touched when flashing firmware.
4. Please follow the guides on how to flash correctly.
Any other questions please ask.

It should be noted that if it's an ATT phone it's Snapdragon therefore permanently bootloader locked, OEM Unlock won't actually do anything, that setting only works on Exynos.
The only root method for Snapdragon is to use a leaked engineering bootloader to gain system access, and you can only install the leaked bootloader if your phone is already running old firmware. For up to date phones there is no root method.

Don't be smart you know how to use Google?

I did google it, I wouldn't have asked for a source if I found something. But it doesn't matter, you're the one making unsubstantiated claims, the burden is on you to prove it. But since you asked for it:

There isn't a single page when googling AT&T S7 Exynos that backs your claim up. The USA also uses completely different network technology than internationally, using the S7 Exynos in the USA is already known to cause issues with LTE, VoWiFi etc. They'd have to do a hardware refresh of the Exynos SoC if they wanted to support it in the USA, which they ain't going to do a for a 3 gen old phone.
