Loki doki - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Just root my phone recently. I'm wondering what is loki? Since some roms require loki. I'm using s4 i337m or a Canadian model. Thanks!

It is a S4's exploit that unlocks bootloader or bypasses bootloader so that you can install TWRP or other recoveries to flash custom roms. If your device has higher version than MF3, you can't use loki doki. Simply, if you rooted your phone with motochopper, that means you are in MDL or lower version in which you can use loki doki. i believe that you are on MF3 or higher, so visit this thread before doing something wrong.

You don't need it at all with Canadian models. There are several threads within the forums that cover this information.

I rooted my phone using cf auto root. It has already custom recovery. It means i don't need loki anymore. Thanks!

[Q]

Hello Xda
I am currently running PAC on an mdl base band. When I got the phone, I it shipped with AMDL and I did and have successfuly used Loki on it since the day I got the phone. With all the recent developments with Safestrap, I wanted to make sure I wasn't missing anything by continuing as is instead of going to MF3 and using safestrap. Am I correct in saying that sticking with Loki is better?
Thanks

Only you can decide what is the best option for you. It is completely subjective. I suggest you read about what SafeStrap has to offer and compare for yourself the benefits of SafeStrap versus MDL (LOKI). I am assuming you already have a decent understanding about LOKI (because you are using it), if not you can read about it as well. Good luck.

on top of stock rom, my stock rom was JeallyBean 4.2.2 i337 mf3 not mdl and i read there are no mf3 files for odin
So i managed to fix this problem just by downloading stock rom for my phone and flashing with safestrap: Galaxy S4 rooted Stock ROM AT&T SGH-i337 MF3 (i found that on google)
The rom i downloader is rooted. and it said to install Loki after finishing flashing rom but i managed not to.
after you finished flashing you need to install also: jflteatt-MF3-modules(attachment) : this will make your wifi to work.
Every thing i just said, worked for me! do this at your own risk! im not responsible for any damages!!!
Wait what if you flash MDL with safestrap, and use goo.im for TWRP? It could possibly brick but just an idea.

It wouldn't. The bootloader is still MF3 no matter what you do to the system, and so it will still be locked with no way to bypass it.

How to install CM10 on my MK2 ATT S4

Hello,
I just rooted my S4 ATT I337 followed this threat: http://forum.xda-developers.com/showthread.php?t=2565758
I'm currently have my phone on MK2 build. Anyone know how I flash my phone with Odin so I can install CM10?
You cannot. We don't have a custom recovery. We have locked bootloaders. All you can do is root.

There are plenty of threads with information in the general section, including a thread convienently named All Things MK2 And NB1. Make sure to check that and read more before asking questions unless you're on an I337m, in which case you can disregard anything I've said ;P

[Q] Cyanogenmod installer confirmed working with AT&T GS4 SGH-I337?

The question is will my device work with the jflteusc version of the CyanogenMod Installer? I have a AT&T Samsung Galaxy S4 SGH-I337. I heard of the new CyanogenMod installer and looked at the supported devices. I saw a jflteusc (US Cellular). I don't knoiw if it will work with my AT&T S4. I don't want to **** up my phone. I'm currently on 4.4.2 NB1 stock rooted. The website I am referencing is http://wiki.cyanogenmod.org/w/CyanogenMod_Installer Any help would be great!

Did you use safestrap and deadly venom kitmat magic tool in install 4.4.2 stock rooted? If so, you cannot get CM to work.
Yes I did. If I upgrade to NC1 stock unrooted, would that work?

You have a locked boot loader that prevents from changing the kernel. So, no.

There has to be a reason why only ATT S4 is missing from the list, right?
Yea I downloaded the app and it said device unsupported
Sent from my SAMSUNG-SGH-I337 using XDA Premium 4 mobile app
Has anyone ventured to trying the installer in the unsupported mode? Is there a reasoning behind this and safe to try if I'm already rooted and TWRP? I thought there already was an ATT compatible build.

If your bootloader/firmware were MDB or MDL you could try it. Above that there is no exploit for the bootloader out yet so you can not install the CM.
Yes I'm on the same adventure with my sgh-i337. I'm going back and forth between MK2 and NB1 ROMs but cannot get MDL or MDB flashed at all. I got them from samfirmware and Odin fails. I tried kies and it says firmware available is MDL ... Well great, but then it says device not recognized!
I'm really torn between why is it we can get to MDL to flash CM?
Instructions:
http://wiki.cyanogenmod.org/w/Install_CM_for_jflteatt
Edit: once updated to MK2 there is no going back. Bootloders are locked and that is the end of the story. No more CM or CWM recovery or Loki ... Just safestrap and custom ROMs.

Just as a final reference for all: CM installer is not for the I337.
On MF3 and above, we have no exploit for ROMs and Cyanogenmod is not compatible with our stock kernel.
Even on MDB/MDL it won't work because you need Loki which the installer doesn't take care of AFAIK (if it were to even let you open it).
