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!

I rooted my AT&T Galaxy S4 i337 a while back using Motochopper and it worked absolutely fine. After installing Cyanogenmod, I decided to go back to stock. I used triangle away and Odin to return myself back to stock, however, I always had issues. When I would recovery boot, I got an error and I couldn't wipe my cache partition. I tried to re-root my phone today using Motochopper and then Odin, but neither of them worked. I got a fail on both of them. Motochopper installed Supersu on my device, but didn't actually give me root access, and Odin just gave me a fail. Now, my phone is working with stock, but I still get errors in recovery mode and I can't root. Can someone please help!?

That's what i was afraid of. With mf3 you can't root with motorchopper or flash roms like you could on mdl. You also can't put on a custom recovery. Give me a second and I'll give you some links.

MF3 has a completely different root and recovery method now. Search the threads and you'll find them. Unfortunately it's pretty risky as you won't be able to flash back to stock using ODIN on MF3.

Because you were on mdl firmware. After you Odin'd it had to have taken the ota update to mf3.

Ok, so I read the links. Now, I'm not so much interested in rooting as I am getting my phone straight. Is there any way to get back to mdl? Will the rumored 4.3 update this month fix that? When I tried to update or recover with Samsung Kies, it said my phone wasn't compatible to recover. Does that mean I won't be able to get the update?

First, there is no way to go back to mdl. Idk if you'll be able to get the 4.3 update but I would assume so since you are on the stick firmware now. But, each new update is going to make it harder to root your phone or run custom roms. So you probably need to choose whether you want to keep your phone stock and take updates if and when they come out. Or have some snooty to run custom roms and root your device and put safestrap on.

I'm going to stay with stock. Will the mdl thing effect anything if I have an issue with warranty sterf?
Shouldn't, your stock mf3 right now.
Bear with me please. Upgraded to S4 from S3 that was running Task650 ROM.
I have searched and am a bit confused with the Locked, Loki Doki, MK2, etc. I have searched and cannot find info as far as what I can upgrade to without causing Locked Bootloader or other problems. I have read the FAQ's and they do not mention what to do if you are on MDB. Phone is 2 weeks old and all I have done to Root with Casual.
So what can I do with MDB without causing problems?
Thank you in advance!!!
You can do everything on mdb as you can on mdl. You can root and put a custom recovery on and use Odin. If it was me I'd use Odin to upgrade to mdl and then put cwm or twrp custom recovery on it. Then a custom Rom. You'll still need to use Loki.

Not much, it's just an update you can take without having to worry of locking the bootloader any tighter.

As jd said, you have freedom and you can take the MDL odin just fine. But never take any OTA's or use any other ODIN packages, and if you're running stock then freeze the OTA apps or it will force update. Other than that remember to use loki when you flash and you'll be fine.

I thought I saw in some rom OPS a few months that devs were recommending to be on mdl before flashing their rom. Maybe when some 4.3s came out. But not sure.
Hey!
I recently rooted my GS4 i337. Everything is all working as of now. However, I want to flash an AOSP ROM onto it. So, I followed instructions and at first, I flashed TWRP to my phone. It said it was successful, but when I go to recovery it puts me in ODIN. I then uninstalled TWRP and got the latest version that is said to support i337 GS4. Flashed successfully, but when I boot it still goes ODIN.
I tried both manually recovery booting with the buttons, and the UI on the actual app. Boots ODIN both ways.
Is there something I'm doing wrong? How can I boot into TWRP or CWM so I can make a quick ROM backup and flash an AOSP ROM?
Cheers! And if this is the wrong section, can a moderator please move it? I'm new to this forum.
Thanks. :laugh:

I found this a video on how to use Safestrap on 4.3.
It's for the Verizon variant but the SE Linux matches, can I give Safestrap a shot?
EDIT: Scratch that, I've found an ATT compatible version (3.71) and it booted into it perfectly! Now I can backup my stock ROM real quick and flash on my new one! Thanks!!
First of all, thanks for reading this...
Here goes the story. I have a Galaxy S4 SGH-I337 AT&T. Yesterday I updated to 4.4.2 OTA. The idea of flashing to google edition ROM came into my mind so I did some research. I found 4.4.2 with NB1 baseband cannot be rooted and it has to downgrade to 4.3 first. So I followed this link:
[NB1►DOWNGRADE★UPDATE◄MK2] ★ [NB1 FULL ODIN] ★ [100% SS ROOTED STOCK] ★ [Mar.23.2014]
http://forum.xda-developers.com/showthread.php?t=2663545
to do so. Everything worked fine. I installed Safestrap-v3.71. Then, I downloaded GOOGLE EDITION 4.4.2 BY Danvdh from (http://forum.xda-developers.com/showthread.php?t=2537495) and followed this link:
http://www.teamandroid.com/2014/01/...42-kitkat-danvdh-google-edition-custom-rom/2/
to install Danvdh GE 4.4.2. The post said it needs CWM however I was unable to install CWM on my phone so I assume Safestrap should work the same. I used Safestrap to install the zip and got a successful message.
HOWEVER, when I reboot the phone, it just keeps rebooting (i.e., power on, Samsung logo, black, vibrate and reboot again)!!
Please help!!
Oh, I did not flash Loki doki. Is that causing the problem???
I don't think that rom will work with ss. If you have an i337 I think you need a mdl firmware.
Edit, looking at the rom I know it won't work with ss.

Yes, safestrap. You can not install cwm on your device. You can only use ss and touch wiz based roms. You might have to Odin back to mk2 and start over

There is a guide below with all the answers you seek young Android flashing apprentice. Please slow down & read it thoroughly before flashing anything. Reading saves phones! If the method or rom you want isn't posted in the guide, it can't be done on your MK2 S4. All the roms that will work on MK2 firmware are listed as well as the way to flash the listed Kit Kat roms too. I recommend you try the At&t roms 1st instead of the international versions. Please thank the op in the threads that help you. Good luck. :fingers-crossed:

You can't flash any AOSP roms with safestrap, only Touchwiz based ones. Your bootloader is locked so it's impossible for you to flash any vanilla android or google edition roms.
The "I337UCUFNB1 100% Stock Rooted ROM" is basically stock GS4 Touchwiz firmware that is rooted.
I tried to figure this out and I'm lost. I've not been keeping up with development on this phone for a while. I'm currently on stock rooted MDL, stock recovery. I'm looking to move to rooted current stock rom. How do I go about this. As simple as just putting a new recovery on and flashing the new one? Or do I need to be careful of anything?
Feels weird to be out of touch with how everything works now.

You need to put a custom recovery on. Then flash the ROM in the recovery. Since you're rooted you could use goo manager to put twrp on

I am in the same boat. Have tried goomanager and rom manager but both failed to load recoveries. It seems they have moved on to 4.4.2 kitkat and no longer work with 4.2.2 MDL. Have also tried to find .tar files for older recoveries and flash with ODIN but no luck. Afraid to OTA update from AT&T and get MK2. Any help would GREATLY be appreciated.

Glad you got it--you can now flash custom recoveries from recovery. I like twrp 2.5.0.2
Don't try goomanager anymore--not needed
There are a couple files to delete so you don't get auto updated. Some have Update in name and one has FOTA. I don't have them in front of me atm
Get a nandroid asap and put copy on pc too
Plus backup efs
Just one last check before I try and mess with things tonight. Since I'm on MDL still, to install a new current ROM (like this one http://forum.xda-developers.com/showthread.php?t=2280556), all I need to do is:
- install a custom recovery (TWRP 2.5.0.2 looks like the most recent)
- backup
- full wipe
- flash new ROM
I shouldn't have to mess with any of the safestrap stuff correct?
Just trying to be cautious.

No SafeStrap. Backup should include System. Make sure to read OP and last few pages of thread for any new info. Make sure ROM doesn't need loki-doki. Most in att forum don't. What recovery are you on now?
