Request for Cyanogenmod for Sprint Galaxu S7 - Sprint Samsung Galaxy S7 Questions & Answers

If any developer has the time, please consider looking into making a cm rom, cause we've managed to get echoe rom working on the Sprint S7.

Idk if it can be done on locked bootloaders that are tw launcher based because Cm is aosp based

True didn't think of that. Hopefully we find a way to bypass that or unlock the bootloader.

The only thing that stops us from having a Cyanogen rom on our phones is our locked bootloaders. It doesn't matter that we have Twiz based OS on our phones cuz when you flash a rom from a custom recovery, it basically writes a whole new OS onto the phone. So whatever OS your running prior to the flash gets overwritten with the new OS.
So the only way we can flash a custom OS is if our bootloaders get unlocked, cuz once that happens we can flash a custom recovery, and from there we can flash whatever rom we want, as long as its made for our phones. First we got to have a working root method, then we have to have our bootloaders unlocked so we can flash a custom recovery, then we can flash away. We have a root method now, so it's only a matter of time until our bootloaders are unlocked. IMO

So wait, I've flashed a custom rom (echoe rom) on the galaxy s7 using flashfire and it works fine, so what would stop Cyanogenmod from working on the Galaxy s7?

That rom is still touchwiz based. Kernel is the same, usually cm/aosp roms use a different kernel or greatly modified kernel.

Is AT&T G2's bootloader unlocked by default?

I see all these threads about flashing recovery and rooting on all carriers, so I just want to be sure, is it unlocked by default? If not, is there a way to unlock it?

no it is not and no you can't unlock it. You can use loki to flash a recovery on it and then flash roms.

Loki is basically a bypass that allows you to have a custom recovery, right? Or is it just like a bootstrap/safestrap that requires you to have the stock ROM/kernel still installed?
And does Loki do a factory reset as if you had unlocked your bootloader?

when I flashed loki and recovery and root I did not have a factory reset so everything was still there. Also it allows you to flash roms you don't have to stay on stock

Coming from a Nexus, the procedure is a little different.
What you do is hook it up to the PC and run a script to gain ROOT. Then you download FreeGee and flash a Custom recovery. Pretty straight up. Doesn't require factory resets at all.
And I DO highly recommend using stock for about a week before you flash AOSP roms. The Stock rom is very nice, feature rich, and polished.
here is a link to an explanation of loki given by the creator. it was originally made when the galaxy s4 came out to get past samsungs security called knox but has evolved to work on other devices like lg. it doesnt support most manufacturers, just the ones dan wrote it to support.

I just want to make sure phones I'm looking at are able to be messed with, so I'm not stuck with something stuffed to the brim with bloat forever. I usually stick with stock for a while before switching to custom ROMs.
One last question (I may be lying about that), does the G2 handle 4-6ft drops well? I read one article that said it's about on par with iPhones there.

Flash T-Mo Firmware on AT&T i337

Hello, I've installed tons of custom roms on quite a few different devices before, but this is the first one I've owned with a bootloader that can't be unlocked and I'm still kind of confused as to how all of these workarounds function and what ROMs they're compatible with. I've unlocked the phone and am using it on T-Mobile. It's currently on the MLD KitKat leaked version.
This is possibly wrong, but my understanding is that you are currently unable to install custom ROMs like CM and Omni on this device. So would it be possible to at least flash the stock T-Mobile ROM instead of AT&T? Right now, I have no access to hotspot, which is included in my plan, and I'd also like to use WiFi calling if possible. Has this been done before and is it possible on my firmware?
Thanks in advance for any help; it's greatly appreciated.

You can not flash their stock firmware. You can, however, use Safestrap to flash a ROM from their section, which as long as it is based from the stock firmware will have those features.
I have flashed HYPERDRIVE ROM with T-Mobile compatibility pack and works fine ! Even WiFi calling works!

Thanks, guys. I just got back from a trip and I'll be attempting this now.
Are there any AOSP-type ROMs that will work with this?

Also, if you havent done so, you might want to enable AWS for further compatibility. You will need to use the stock AT&T TW ROM in order to do so.

Since you're using Safestrap, you can't flash a kernel anyways due to the locked bootloader. You should be able to go ahead and flash that.

Is it possible to flash Galaxy S7/Edge to official Android Marshmallow?

Hi guys I'm new to android and rooting and this seems to be really a noob question. I am wondering if it is possible to flash galaxy s7 to Android Marshmallow rom just like Nexus phones.
Thanks
You mean go back to stock touchwiz firmware? Yes you can. Go to Samobile, download the firmware for your device and flash it with Odin.

Nexus phones run stock aosp roms, if that's what you're asking about, it depends on the phone having unlocked bootloader and root, then you would need a stock Android rom for your specific device, you can't just download any rom and flash it, you kill/brick your phone that way.

Yes thats what i mean.
Thanks for reply. I know there have been several custom roms in the rom forum. So i just want to check if theres a way to flash google rom like nexus.
If we can flash custom roms on galaxy s7 (of course rooted), why cant flash nexus rom?

Because the custom roms are based on Samsung touchwiz. An AOSP Rom needs to be made for the specific device. And that means the developers needs the sources for the phone. In this case the S7. And they are not public on the exynos devices, unlike the Qualcomm. So it's a try and failure. That's why it most like will never be a stable release of AOSP on exynos ( and Qualcomm since they have locked bootloader)

Can you downgrade to a custom ROM if you're rooted and already updated?

Hey guys, everything I've read has said once you update beyond 4.3 you can never go back down because of knox. I also saw someone mention you actually can downgrade to a custom ROM based on a previous build just not to stock. Can anyone clarify this for me? I'm not worried about breaking my warranty since it's long since expired. I'm on the rooted 5.01 Goldeneye ROM and want to go back to a 4.2 ROM. strictly for tethering purposes
What is the model # for the s4?
It's the AT&T sgh-i337
With a locked bootloader, the phone is limited to customs roms based off a stock Samsung rom. Aosp and cm will not install or run.

Thanks for the reply! So if I stick to TouchWiz based custom roms I can downgrade without bricking my phone?
Yes, just don't touch the bootloader or modem.

Ok thanks. Can you suggest a good 4.2 ROM? Also, since I'm already rooted with safestrap, do I just wipe and flash the new ROM or do I need to install a different version of safestrap and kernal etc? I'm have trouble finding any instructions on how to downgrade. I appreciate all your help!
I can't recommend any 4.2 roms as I don't have the phone. Also, I don't think such an old rom will work on an lp modem and bootloader.

Ok so based on your statement "I don't think such an old rom will work on a lp modem and bootloader," does that mean you actually don't think I can downgrade?
You can try but I don't think you will have a functioning phone in that the imei will not be properly displayed which means the phone wouldn't be able to connect to the carrier.

has anyone rooted the s7e running 7.0

Has any one root the T-Mobile s7e with it already on 7.0?
I have been looking but not sure . I tried to root with the method on here but I get stuck in a bootloop when it restarts after flashing the AP boot file in Odin I have tried several ways. I want to know also. I'm running 7.0 and g935t .
Yes been out for a few days, haven't tried myself yet.

Using ambasadii rom for few days and it works nice

But you need custom recovery, and rom is debloated + rooted
Just get a custom recovery, disable encryption and flash latest SuperSU 2.79 or Magisk. All good
Am I missing something.....why are the people above me saying to put a custom revovery on tmobile variant.... afaik that's not possible.

I think that every exons proccesor (Europe) can be rooted.
But im not sure. I got my S7 from germany and its unlocked. No TMobile or other carrier.
Everything works good ?
T mobile is snapdragon. There is 7.0 root, it uses another engineering Bootloader
Right but there's no custom recovery, no custom kernel, no custom Rom, which is what the user was suggesting. Doesn't make sense. At least not for US variants.

OP, i thought was asking for root. Flashfire is basically our only recovery atm for usa hence locked bootloader.. no custom kernels but we can tweak kernel via kernel author. We have custom roms but it's TouchWiz based.(stang 5.0 rom is awesome) Still better then having nothing imo.. xposed+root apps+romcontrol+system write, makes sense and worthwhile for me.
