[Q] Kernels on other SGS3 variants? - Verizon Samsung Galaxy S III

Hey everyone,
I've never owned an unlocked phone before, so I apologize if this is a stupid/obvious question. I'm on the Verizon variant of the S3 and I'm looking around at other forums here and seeing some interesting kernel development, particularly faux123's kernel in the T-Mobile thread. I know that us Verizon folks used a Sprint verizon of ktoonsez's kernel before a Verizon version was released, so can it be assumed that an AOSP-based kernel for a T-Mobile or AT&T phone can be used on Verizon as well? I know Sprint is more similar to Verizon than TMO or AT&T, but as far as I can tell, kernel doesn't really touch most of that stuff.
Here is a link to the kernel in question: http://forum.xda-developers.com/showthread.php?t=1785472
If anyone knows whether this will work on a Verizon phone (or if I'm taking a major risk by flashing it, or if worst case scenario I just won't boot and I restore a backup), I would appreciate you passing on your knowledge.
Cheers

Well I got impatient and figured I would just flash it and see. Works fine as far as I can tell. Still, if anyone can answer, should this be applicable to all kernels? I'd love to test out all the AT&T/T-Mobile kernels (AOSP of course).

Why is verizon network a different Root process than other carriers?

Couple questions:
Why is it different for verizon vs other carriers? basically, Why can us verizon users not use the same method used for sprint, Tmobile or ATT?
regardless of the carrier you are on, once you are rooted can you flash any ROM? Example, Say I root when I get my phone (From verizon) and root, there are several choices Id be interested in the international S3 development. I saw a couple instances where US version phones had some issues flashing some of those ROM's.
IF there are issues with flashing certain ROM's, how do you know which will be safe for US version phones?
I am coming from a rooted thunderbolt and I dont recal ever having to worry about these issues, which is why I am looking fro clarification. Thank you for your help in advance. Seeing several cases of bricked phones, I'm just wanting to make sure I fully understand.
us variants use a different chip set then the international versions of the s3. Lots of threads about it

You didn't have to worry about this because with your Thunderbolt, your xda forum wasn't joined with the other provider variants of the Thunderbolt. I think the fact that xda joined all the carriers together is going to end up with more people that don't understand how this whole thing works and more bricked phones.
The international phones are more like the droid incredible s and incredible 2 difference. They're both world phones but one is international. They seem to be 100% identical but they aren't and therefor cannot accept each others Roms (on 99%
Of the cases) just be sure t read the op of any Rom u are interested in. They will say not to flash if u are or aren't an international phone

US Cellular Variant Offical Thread

Hey guys, the Samsung Galaxy S III is finally coming to US Cellular this Thursday and/or Friday.
This is the official thread for the US Cellular variant of the phone.
We will discuss mods, flashing, rooting, and etc.
In for my 2 friends on USCC whose phones I'll be rooting (for tether). Hopefully it won't be locked like VZW.

It won't, I spoke with a US Cellular representative today and it's where I got the release date and other details.
The thing is, that the phone does have a lot of similarities with Verizon, so the devs have 2 options.
They can make one for US Cellular and edit it for Verizon.
But as Verizon is a larger carrier, they'll probably get the Developer's edition of the phone and then at some point make a root for the US Cellular version.
You think that CyanogenMod 9 or 10 will be supported for the USC variant?

There's no reason why not.
As far as root, the CWM flash method has worked on all variants thus far, I don't see why it won't work on the USCC phone.
I am switching this fall when my contract is up in Verizon to US Cellular. What will the dev scene look like on this phone? Will it be easy to port ROMs from other GS3? If there are very few devs working on this phone, how easy is it for a end user to port the ROM from another GS3?
since I already have a mini sim and a lTE acount thats active, from my Galaxy Nexus on verizon, can I just pay cash for the us cellular version and plug in my active sim and it will work?

Well, there are already people getting the phone today, but I know that past phones like the Mesmerize and the Aviator have been Cyanogenmod supported, and Root supported.
Do you happen to know which carrier US Cellular has the most similarities to?

The US Cellular variant of the Galaxy S II shared a lot of similarities with the Epic4G Touch.
Well, as US Cellular is finally starting to grow, I've seen a lot of developers for AOKP and CM9 discussing the possibilities of ROMs by making it for the 4G Touch, and just porting it over by changing a few things.
I can't answer that last question as I really have no idea on porting ROMs, but as I said in another post, it's either closer to Verizon or Sprint.
But for the S II, I've seen a few threads that it was very easy, but that they just had to change a few things, so I'm assuming that it's not that much of a hassle.

I've tried Googling that but I can't seem to find an answer.
Some answers say yes some say no, but I think that US Cellular has more similarities to Verizon than any other carrier, at least that's my speculation in terms of radios, as they both use the same spectrum.
But you can go to the website and go to a live chat with a representative and ask there.
Has anyone rooted this phone yet? Can we get our own section?
Bump for a fellow U.S. Cellular S3 owner. Would love to see it rooted.

The instructions at galaxys3root.com works for US Cellular.
So it is confirmed that this phone has an unlocked bootloader?
Has anyone tried and can verify on U.S. Cellular that they have used galaxys3root.com and it worked?
this phone can be rooted with the method that team epic uses for the sprint version. I dunno what the website you're talking about does but it is the same method as it is with all the other carriers.
I would love to see a separate section for us, no we aren't gonna have a whole lot of development going on compared to the big 4 but it would be really nice to have a place where we can have specific discussions and rom ports and things for just us.

Does anyone know if a verizon mini sim will work in this device?
Yes that site just has a set by step guide for installing the Team Epic recovery using ODIN and it worked on my US Cellular Galaxy S III.
Seconded on the separate forum idea. I think there will be more than enough people to have one. I know a lot of people is moving to this from the Desire and that had a decent sized community.
Successful root using teamepics procedure.
Agree with vex and all the rest. A separate forum for USCC GS3 owners would be wonderful.
Who would we contact to get a separate section?

Is this phone for me?

Hello, so as an AOSP lover and on verizon, this phone could be a good option about me. When I bought my S3 years back, I only used AOSP roms. Eventually, I got a note 4 in hopes of it getting root. Well... Obviously didn't go well, so I'm rolling on my S3 again. Would it be worth it to sell my Note 4 and buy this phone? It has better specs than an S3. So a few questions...
How does the development compare? I see we have some CM13 builds w/ probably some official builds soon. Does it have exceptional development?
What is the process of rooting like? From my understanding, you unlock the bootloader similar to a nexus device and then flash SU in TWRP, yes? So it won't matter what android version it's running @ the time?
How exactly do unlocked phones work? I've only used two year contracts in the past, I don't understand the whole concept of unlocked phones, to be honest.
Will the bootloader be able to be unlocked if I use verizon? I planned to buy the phone straight from moto so it is unlocked, but my friend's OG Moto G isn't able to be unlocked even though he bought it from Amazon (He is on verizon).
Thanks, XDA.

The Unlocked Galaxy S8+ on T-Mobile

Hello,
I am planning on purchasing the Galaxy S8+, but I think I'm going to get the unlocked version when it is released. My question is whether T-Mobile wifi calling would work or not on this version, and if it doesn't, then would it be possible to flash a T-Mobile rom on my phone without any problem? Would all T-Mobile features then work as if it was an official phone from T-Mobile? Also would there be any downsides in doing this? I know no one knows right now for sure, but I'm just asking based on the past and whether it has been done before with the galaxy s7.
Thank you!

I don't believe wifi calling will work on the US unlocked version, but if Samsung manufactured the phone's the same as the S7, I.E. same hardware, then you should be able to flash T-Mobile's firmware with minor to no problems (I just flashed AT&T firmware onto a Sprint S7 and the longest part was downloading the firmware. I didn't gave any issues while flashing. But there's no way to tell we have that capability with the S8 until the phone has been released.

If you flash the T-Mobile firmware, yes. You should even receive updates from T-Mobile as well.

It's been done to the S7 countless times. Check out the forums and you'll see. I'd say the biggest downside is carrier bloat and certain carriers block some features that Samsung included in the phones.

Question about the Sprint variant

Ive been on Sprint for a good while now and I've had Nexus phones for years now so I'm not used to having to worry about the different versions and if I'll get to use custom roms or not.
But because I remember how much life sucked pre Nexus, 5,6,6p on Sprint, I was just wondering if this variant of the s8 is destined to live a stock rom life? I see the international and TMobile and att versions etc are already flourishing, but not a whole lot here.
Just trying to make my decision of do I upgrade or finally move to a gsm carrier.

Most of those roms are Universal for all carriers. You just have to flash your sprint CSC/Userdata to get all network features. Check Verizon or ATT threads.
