Hi everyone. I'm picking up an at&t i337 that's running the stock JB 4.2.2 UCUAMDL firmware, and has not been yet upgraded to 4.3. I intend to flash a custom recovery, ROM, kernel and I want to flash the MJ6 modem. Here's my question; if I flash a 4.4.2 AOSP ROM, can I safely flash the MJ6 modem that comes from 4.3? I'm running the MJ6 modem on my other S4 thats on the MK6 firmware with safestrap, and it's giving me great reception, downloads, etc.
Thanks,
Mike
Yes. If you root your amdl phone and put a custom recovery on it you can flash what ever you want through it.
I used motochopper method back when I did it. It puts root and twrp on for you

Thanks, both of you. I appreciate you getting back to me. It was TOUGH finding an S4 that hadn't been updated yet, so I want to make sure I don't screw it up.
Thanks again!

HI there,
DOes anyone have a solution for us stuck on MK2?
I have the following problems:
I bought this i337 second hand, and it came with UCUAMK2 firmware.
I rooted it with SAFEROOT (saferoot.zip). That worked fine.
But I cant install LOKI, to get the ClockWorkMod, so I can't install Custom ROMs.
Because when I type in the commands in Android Terminal, to flash loki's CWM recovery, it says :
[+] loki_flash v1.1
[-] Loki aboot version does not match device.
SO i figure, I have to revert back to MDB or MDL firmware.
BUT when I open ODIN, and try to flash the official firmware:
1. I337UCUAMDB_I337ATTAMDB_I337UCUAMDB_HOME.tar.md5
it FAILS in ODIN, so I (try) to flash this:
2.I337UCUAMDL_I337ATTAMDL_I337UCUAMDL_HOME.tar.md5
but that FAILS also!!!!!!!
SO should I install SAFESTRAP?
Some ppl complain, that screws things up, and end up in bootloop, and can't remove this SAFESTRAP...so i dunno if
i should install it.
Does flashing via/using ODIN FAIL==> because my bootloader is LOCKED?
Can you tell me how to Unlock my bootloader????
I need to go back to MDB or MDL, because otherwise I can't unlock the carrier restriction, since I'm on Vodafone,
and not on AT&T!
Plus, I was always installing custom Roms on my S2, S3, and all my other android devices since 2009....sorry to see
that the S4 is
such a headache....
Can you help me out please, seeing how good aof a DEV you are....?
Please and thank you

You SOL buddy. Sell the phone and get something else. You will never be able to downgrade

You will need to use safestrap.
Loki does not work with MK2 because they patched it in the MK2 update.
At this point in time the bootloader cannot be unlocked.
el o el
The s4 is nothing like previous samsung devices...at least on att, the bootloader is locked, safestrap is your only option.
Also keep in mind, att stated about a year ago they will no longer be supporting phones with unlocked bootloaders...so the problem you are experiencing now can be expected on every new att branded phone

There is NO WAY back from mk2. You can flash custom roms ONLY with Safestrap. No CWM no TWRP. Read this guide, it has everything you need to know for the S4. There is nearly 30 custom roms tested & affirmed working. Good luck & happy reading.

SGS4 AT&T i337 on Stock MK2...jeboo kernel/recovery needed to install SHOstock v3.0 ?
I am very familiar with custom roms and your kernels, from always using them on my SGS2 i777 (AT&T), but i just bought an SGS4 i337 AT&T, on MK2 baseband, and everybody suggested I should install the SHOstock v3.0 for the i337 (http://forum.xda-developers.com/show....php?t=2305752).
Problem is, I am sooooo confused now, because there is jeboo kernels: (Jeboo_Kernel_i337_v3_0a-i.zip, Jeboo_Kernel_i337_v3_0a.zip, Jeboo_Kernel_i337_v3_0.zip, Jeboo_Kernel_i337_v2_2.zip)
...than there's your RECOVERY: Jeboo_Recovery_v2_1.zip
so Im very confused now how I should go about installing our most awesome DEV shoman94's SHOstock v3.0) ROM...==> THAT I DUNNO WHAT SHOULD I DO ANYMORE.....
1. Because, on the thread there (http://forum.xda-developers.com/show....php?t=2305752), in POST#1 it says , in the Instructions, that :We must be running a custom recovery using Jeboo's Recovery from Post#4 which is your Jeboo_Recovery_v2_1.zip
2. But how should I run the Jeboo_Recovery_v2_1.zip RECOVERY, if Im on SafeStrap 3.71 (which is a recovery also)???
3. If i flash Jeboo_Recovery_v2_1.zip, wont that brick (or softbrick) the S4?
4. Or if I flash Jeboo_Recovery_v2_1.zip, will I end up having 2 recoveries? Or will I only end up with having only the Jeboo_Recovery_v2_1 ???
5. In POST#3, it says that:
IF YOUR PHONE HAS MF3/MK2 BOOTLOADERS, YOU MUST RUN THE MF3/MK2 STOCK KERNEL. DO NOT TRY INSTALLING ANYTHING BELOW UNLESS YOU HAVE MDB/MDL BOOTLOADERS THAT SUPPORT LOKI!!
So, should I NOT flash your Jeboo_Kernel_i337_v2_2.zip , since I am on MK2 stock kernel/baseband/bootloader....?
Check it out: http://i.imgur.com/cNWijKF.png
7. I mean, what is BELOW MF3/MK2 and ABOVE MDB/MDL? Because it also says, that: All binaries posted here will be loki'd (as signified by the .lok extension).
SO, keeping in mind that Im on Stock MK2 , but also Im ROOTED via SAFEROOT.zip (as you can see in the pic above: (http://i.imgur.com/cNWijKF.png) , can someone please tell me if I should flash this SHOstock v3.0, and more speciafically, WHICH, IF ANY of you jeboo kernels and Jeboo Recovery should I use?
Can I bug any of you to tell me the exact steps on how to get this SHOstock 3.0 on my i337, if I'm on MK2, rooted, and safestrap-ed?

You are making it too hard. You need to be on 3.71 Safestrap to flash Sho's 3.0. You must use default (stock) kernel. You can not flash any other kernels period. And no other recoveries. And no 4.4 or aosp roms. I am not on SafeStrap as I have a MDL phone. So, you need to go the SafeStrap thread and read up on flashing a rom on SafeStrap. There are a couple threads on the subject. Read all you can first and make any backup your phone/recovery allows before flashing. Also, do a clean wipe before installing rom. That may be different then a clean wipe on MDL/Custom Recovery, not sure--:good:

Phone came from the Store with MDL, ( I see it on the Original box: SoftWare Ver: UCUAMDL....
The guy I bought it from rooted it, and loki-ed it... how did that OTA come through, I wonder? Once rooted and LOKI-ed...the OTAs shouldn't come through, right?
Sounds like the seller messed up and flashed back to stock. He was probably selling it to cut his losses.

Answer, yes & yes. There is plenty of custom roms for mk2 in the All things mk2 guide. You can also upgrade to 4.4.2 Kit Kat now as well. Forget about MDL cause there's no way to go back to it.

But if he had it LOKI-ed, that means he was just fine on MDL, no need for SafeSTrap, unlocked BL prolly ... he was free to install CM, GPE, AOSP, PACman and all these ROMs....so why flash it back to stock MK2? I mean, cutting his losses....that's funny...I mean, unless the MK2 OTA from AT&T came forced.... WHo knows...
He probably didn't know what he was doing, got stuck, and tried to Odin back to stock. Only he used the mk2 package and not the MDL one.
Stuff like that never surprises me anymore. People don't want to learn/read. Just give me the file so I can flash it.

Just ask for a little help, ...why is that so hard, right?
I've been reading up on all I could, and now that I "kinda" get a better understanding of how things lay with the i337 MK2...I can make a decision to flash, and stay stock...
Problem is, I have been flashing since 2009, so I can't imagine owning a droid, AND NOT FLASH IT!!! IT KINDA DEFEATS THE PURPOSE OF OWNING AN ANDROID, right? hehehe
I know that feeling. At least Safestrap is a decent option. I rushed out to grab my MDL 32gb one before they updated their stock.

i root my gs4 with odin, everything went fine but I wanted to get my gs faster so i downloaded kernel for gs4 and flashed it. mistake here. i didnt check if it supports 4.4.4. it only support devices under 4.3 so.. no wifi. that was the problem i had other than that, all was good. than I downloaded some OTA file for my gs4 and when i tried to flash it with safestrap, it kept said fail. so i thought it's maybe because i already have OS installed... so i wiped system,data and i tried to flash that OTA file, fail again. now im screwd. there is no OS on my gs4. when i trun it on, it vibrates, than reboots and than goes into Odinmode and say something like "nornal boot not possible" in red.
so i spent couple days searching how to get my phone work again but everything i tried didnt work. and for galaxy s4 sgh i337 nj4 version 4.4.4 it even made me think it was made just for me.
i tried kies, failed it told me to do emergency recovery but my phone does not show on list.
can anyone please help me.. Im new to Samsung Galaxy..

You'll have to use the ODIN file from this thread: http://forum.xda-developers.com/showthread.php?t=2674223
Flash that in ODIN, use the rootable version if you want to root it using towelroot.
Besides that, you can't flash any custom kernels on the S4 unless you're on the 4.2.2 MDL bootloader, and there's no way to get back to that from 4.4.

i have rooted OC4 installed on my phone and have i've been reading up on OCTos and their 6.0.1 custom firmware (found a good link too: http://www.teamandroid.com/2016/01/20/update-att-galaxy-s4-i337-android-601-octos-marshmallow-custom-rom/ ) . and now am more confused.
it should be simple from what i am reading.
1) backup everything
2) revert to 4.3 (mk2), root, and install ClockworkMod 10.2+
3) install custom rom 6.0.1 OCTos
however, i'm reading on this page (http://forum.xda-developers.com/galaxy-s4-att/general/guide-odin-to-stock-updating-rooting-t2926642) but it states >> Once you flash NB1, you CANNOT go back to MK2. <<
So now I'm trying to figure out exactly how i can get the OCTos onto my phone. what guide should i follow !?!?!?!
:silly:
They meant the MK2 boot loader based devices, same with MDL. Aside from a few exploited boot loaders.. it's been the general consensus that they're all locked up, therefore.. only stock roms. The lowest boot loader you can possibly be on is NB1. Download "Terminal Emulator" for the Play Store and then when you open it up, type the following:
getprop ro.bootloader
^ exactly like that, then see what it says. The last three characters (MDK, MDL, MK2, NB1, NC1, OC3, OC4)--that's how you can figure out which boot loader you are using. I am on NB1's bootloader but I can still downgrade to MK2, i.e. Android 4.3, and still have it work.. only because of how the roms in these threads are rooted and the fact that they're stock, aside from a few other small details. When they say OC3 or MK2, or NB1... whichever.. then typically they mean the boot loader when saying you cannot revert. Definitely cannot revert to MK2 bootloader after taking an OTA update.

Even though it was not mentioned, the article appears to be written for the SGH-i337 with old bootloaders (MDB, MDL). These are the only two bootloaders that can be exploited and installed the custom recovery like CWM or TWRP.
Since your bootloader is OC4 you can not install the CWM or TWRP. You could try flashing with safestrap though. If that custom rom is not written with Aroma then you could also try to flash with flashfire. These are the only two options for you.

Okay, yeah.. you're not on MDK or MDL, not even NB1.. you're simply on OC4. You aren't going to be able to do any flashing of any Custom Roms that are not Safestrap compatible (touchwiz)
Good luck.. you can't go anywhere backwards, not even OC3. That really sucks. I'm sorry. It looks like you took the OTA's.
I can still ODIN to NB1 and that was because I never took the OTA update. I got lucky.. I can still choose between kitkat and lollipop. You can't. You might be able to with someone's help.. but your bootloader is OC4.. that's a problem. You more than likely will have trouble doing anything unless it's not MDK/MDL or even NB1 based.

Yeah.. You might have a shot with FlashFire. I might test that via the NB1 bootloader that I'm on but I don't think it matters that much aside from being able to Odin back to 4.3 software.

FlashFire came out with another release (0.32) that seems to have an AROMA emulation option.. my guess is that it's still in testing, but it's worth a shot even without it. The way I have OC3 with the NB1 boot loader is because of FlashFire.. Safestrap.. it's been awhile since I've used it. I've tried recently for other ROMS but you can't do a custom kernel.. that's the reason most custom roms aren't able to work, i.e. CM v13 runs a totally different kernel. It's not just TouchWiz now.. now it's just stock kernels.. at least via SafeStrap. So far I've gotten none to work with SafeStrap aside from Stock rooted roms. OC3, OC4, and if I felt like it, OK2.. but why even bother with OK2, I'm not gonna see any difference given all of the patches you can use with Xposed.. including any memory leak bull****, that's all good now in 5.0.x -- 5.1+ has that patched up.. and OK2 certainly isn't 5.1. I don't see any difference between OC3 and OC4.. and if my opinion counts for anything.. the one thing that I noticed (bloatware script ran and other apps not needed were frozen for both) is a very high amount of battery usage with OC4.. same userdata, same everything.. and when you flash the kernel, the modules, and move up to OC4.. it's still the same looking.. feels the same.. more ram used.. OC3 is superior in this instance. I'd love to try and give an AOSP rom a shot.. but.. via SafeStrap (someone made a guide for those not on the MDK or MDL boot loaders) .. eh.. no luck. That was all via SafeStrap. I'm just putting in my two cents. I think development for this phone is finished.. no one has come out with anything new aside from the SafeStrap kernel workarounds.. not many FlashFire users.. and the one that used to find every single exploit is now EMPLOYED by Samsung so his development.. gone. That was a huge kick in the ass to this entire community. Plenty of people around, just.. they don't give a **** about the S4 with boot loader all locked up. NB1 was an accident for me.. I was on MDL for a long, long time.. I really ****ed that up or I'd be running MarshMallow already It seems to run best with KitKat, but a lot of AOSP roms have shown huge differences in MarshMallow.. oh well. Can't try it at the moment.
Unfortunately I can't remember what I did in the past to this phone, but I have never had luck with OTA updates. I'll have to see if I can find my note to see what I originally did on this stupid thing.

Since you are on OC4, the lowest you can go is NB1 (kit-kat).
So I'm currently on the Hyperdrive rom on Android 4.4.2, and I am thinking of upgrading to Lollipop, but the only thing that is holding me back is that if I upgrade to lollipop, I will not be able to unlock the SIM.

I am sure you are not talking about bootloader unlock (exploit).
I am using lollipop now. I unlocked my sim when I was using jelly bean. Sim unlock is based on the phone IMEI. As long as your EFS partition is intact, you should not be worrying about that.
So if I do Odin/FlashFire to Lollipop, my phone will remain SIM unlocked?

Which bootloader are you on? If you're on MDL or MDB , do not upgrade to lollipop unless you flash the stock based golden eye or gold finger roms or any other AOSP lollipop rom. If you are on any other bootloader aside from MDL or MDB, go ahead and upgrade officially.
Your phone should remain sim unlocked if you use a custom rom to upgrade like the ones meantioned above.

Are you on safestrap? If you are, safestrap works well only in kit-kat. It is a pain to use safestrap in llolipop. I use fashfire instead.
Since you are on custom rom all you have to do is install flashfire and flash the rooted lollipop rom. The instructions can be found at here.
The instruction are written for the latest lollipop rooted rom (OK2). I stay with OC4. If you want to upgrade to OC4 do let me know. I will give you the link for the OC4.
All the necessary files and instructions can be found at here.
You might also want to download the NB1 firmware cooked by Muniz_ri. If you soft-brick your phone in the process or in the near future, that is where have to start with.
If you have questions please quote this in the reply so that I know you have a question.

If you are on safestrap, you might need to uninstall it first before you upgrade to lollipop.
Well OK2 was released after OC4 so it might have some better features. But I did not have a chance to be on OK2 for long to notice it. When I was on OK2 my back button stop working so I had to downgrade to OC4.

Thanks for clearing the air man, really appreciate it. I think I will go with the Thor ROM because it looks to be the best.
You mentioned safe strap was wierd with lollipop, in what way?

They did not make safestrap for the lollipop. Safestrap only works on NC1 kernel. So if you were on lollipop and safestrap installed, everytime you reboot you need to tap the proceed several time finish the boot. Also if you want to use the safestrap to flash something or backup, you need to run NC1 flasher to reinstall the NC1 kernel first. Once you finish your deed, you need to flash the lollipop kernel back. That was why I said using safestrap in lollipop is a pain. You can read about that in this forum.
Download and keep this NB1 firmware. If you softbrick your phone this is the only thing that can save you.

Downloading the file and I'm gonna keep it on my SD card. The several time pressing thing I already have to do on my phone so I'm fine with that. Where do I get the NC1 Flasher?

You need to go to download mode so that you can flash the lollipop bootloader . If you boot into lollipop your modem, etc might not work properly.
