Dual boot Guide? - Sprint Samsung Galaxy S III

What is the best way to make dual boot for Sprint galaxy s3?
I have stock jellybean 4.1.2 and want to dual boot with CM 10.1.2.
i have already rooted my phone.
thank you very much

Sorry for that message, I've posted to the wrong forum! To moderators: pls delete this, I cannot do this, at least in Tapatalk...

There are Siyah and Googy-Max kernels for S3 with dual boot feature but AFAIU you cannot use original kernels for your systems with them, your all systems run on Siyah or Googy. So, it is not kexec or dual booting support in bootloader... It would be great if somebody could confirm this (thanks)! And if there are other possible choices...

Those kernels are only for the international version and should never be flashed unless you want a brick instead of a phone.

^ this and please edit and remove those kernel names before a noob here flashes any of those kernels and then has a 600 dollar paperweight.

Welcome to android. Definitely got a good device for first android experience. Well now since you are rooted you will have to flash a custom recovery. You can download the goo.im app from the play store to get cwm recovery. That way you can flash anything to any partition within the phone. Now is that kernel for the t mobile s3? If its not, then I don't recommend flashing. Just flash what you find here. Ktoonsez makes great kernels. There are also stock over clocked ones and others as well. Once you have cwm OK installed then go ahead and download the kernel using your phone's browser. Then to boot into custom recovery, power off the device and when powering it back on press and hold the power and the volume down button. When the device vibrates once, you can then let go and and from there cwm should work and then flash file from .zip and look for your downloaded kernel and flash it

Do not flash anything to your phone that didn't come from this forum (TMo S3). In other words, don't flash that kernel you were talking about. There are certain exceptions, but just follow this rule: do not flash anything to your phone that didn't come from this forum (TMo S3).
you used http://http://forum.xda-developers.com/showthread.php?t=1695238 this to root your phone? - that thread is for international S3 version
and your phone is TMO right?hmmm...just like what Aerowinder said Do not flash anything to your phone that didn't come from this forum (TMo S3).

If your phone is an I9300, stop posting in this forum. It's a JTAG waiting to happen.

**if your still here**
1st. You cant use anymore Ktoonsez kernel or other kernels and ROMs in this thread you will end up in the customers service station cuz you said its a GT-I9300 (international variant of S3).
2. Your S3 is not a FAKE we have 2 different worlds
good luck with your phone

Port unofficial stock 4.2 rom

Is there any skilled developers that can port the pre-release 4.2 rom released by Samsung for the S3 I9300 so it can be flashed on to my Telus I747M S3.

You don't want to flash a international version of the firmware to your canadian S3.. That will brick it.
Also, if you searched a little, you'd know that we have 4.2.2 ROMs all over here. Please take a couple hours and go read the stickies.

Ok and when I bought my phone I did try flashing the other i9300 rom, but it only soft bricked the phone. I easily unbricked it by flashing the stock rom. It's just that I noticed that some developers ported some roms from sprint to AT&T. What I really wanted was multi-window. But thanks anyways.

Should've been clearer with your question. Either way, don't flash a I9300 ROM
As for multi-window, some ROMs offer that feature but you'll have to search for them as I don't use it myself. Sorry I can't be of more help.
Good luck!

Its easier to go to and from AT&T, Verizon, Sprint and T-Mobile because of the similar hardware. I'd you need a port its pretty simple.
Unfortunately the international ROM has different hardware (quad core CPU, 1gb ram) which makes it very difficult to port over to our ROMs. Most devs don't even bother.

Oh I see now, thanks for the info.
I am trying to understand that porting process as well. Could you not flash a bootloader and a kernel to make the i9300 rom launch on the i747? Sorry I was just wanting a touchwiz rom that was later than 4.1.1 for the i747. Sorry I am sure this is a ridiculous question but I just want to understand the portion of this that makes it so difficult. Thank you.

S4 port for S3

Is anyone working on a port from the tmo s4 to the tmo s3?? It is 4.2 TW isnt it?? Would love to see it..
I have started to look into it but may need custom kernel, and not quite sure all the files I need to get it to boot... will keep this thread updated as progress is made

There's GlamourS4 for the international S3. It's still buggy, but once it gets better, could anyone port that? I'm not sure how difficult porting can be though..

I believe the international s3 is different from our phone. Theres's already custom roms for d2tmo for the s4 so i would say it would be easier to port from d2tmo S4 then it would be from the international s4

Thats all anyone could ask bro.. thanks
I know it's a different model, but wouldn't it be easier porting a ROM from a different S3, which would be more similar to our phone, than a completely new S4? I'm sincerely asking because I don't know much about porting and all.

Touch Wiz is Touch Wiz.. Tmobile is Tmobile. A Tmobile rom would be much easier to port then an international s3
the i9300 and t999 are to different due to the cpu . if you can trick the i9300 rom to think the t999 is the i9300 than maybe its pssible
Ok so its been slow going but I finally got a boot logo and animation but stuck in boot loop. Anyone know how to force 4.2.2 to enable android debugging? As of right now I am using all 4.2.2 files, mostly from s4 but needed kernel an libs for cooked rom. Will let you know how it goes.

I suggest you better stay on Stock ROM and do not flash international version ROM for your phone, because international version uses Broadcom A9 Dual-core processors, but yours are using Samsung Exynos Quad, flashing will result in brick. And the device you have is a rare variant because it is not available internationally.
By the way, does korean Grand have dual-SIM support?

awts! thank you for the advice. All i want is to removed some bloatwares or korean apps. My SHV-E270S has not DUAL Sim. It is only a single sim. Is there a chance to apply a custom rom for it?

As I say, I don't think there is custom ROM for it yet, but still I liked Samsung stock 4.1.2 ROM, all you need is to root and freeze it using Titanium Backup. I am not sure you can use Choto method to root your phone...
I suggest you ask here for confirmation before rooting your phone.
If root is not possible, go to Apps manager > Disable those apps you don't want.

It uses 1.4GHz Quad-Core Exynos (same as the S3). Other spec just same as our Galaxy Grand.

[Q] Android 4.4.2 KitKat For T-Mobile Samsung Galaxy S2 SGH-T989

Hi Folks,
I am going to upgrade my T-Mobile Samsung Galaxy S2 SGH-T989 to Android 4.4.2 KitKat. The phone is currently locked to t-mobile with the stock rom 4.0.4.
My question is that; do I need unlock the phone FIRST, and then I can upgrade the rom?
Thanks.

Not sure, mine came factory unlocked for use on any network.
There's a post in the general section that covers permanent unlock, you might read through it.
Yes. Unlock, install custom recovery, flash SU binaries, boot, install super SU.
The unfortunate part is most links on XDA for some of that are dead. Need to search Google.
Also, good to Odin flash 4.1.2 first and make sure it works. Then recovery, root, etc.
