Flashing the modem has nothing to do with the ROM and so would work. I am not 100% sure that regionlockaway would be able to unlock while running custom ROM. There is no harm in trying. But, it definitely works while on stock ROM and with MF3 modem.

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.

Should have said. I do also have TWRP on it now.
What advantage to MDL is there?

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.
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!

Ok, thanks to k1mu's guide here

I was able to root my phone properly. The key reason to root the phone was no access to tethering. Details for my situation:
Samsung S4, i337, MK2, andriod 4.3 from AT&T. I unlocked it and have been using with Rogers here in Canada but the tethering gives the Mobile data not available/invalid sim error.
I researched for solutions here and on google and all solutions required root, so I rooted the phone using the guide mentioned above. After that I used the method in this link
http://forum.xda-developers.com/showthread.php?t=2535141
However, since I am using non-AT&T sim, this does not work any more. Further I uninstalled all AT&T apps using ES file explorer but still no luck.
Then I figured out and tried other solutions like FoxFi, etc etc.
Then I used the framework file from the thread below which was able to turn the toggle on.
http://forum.xda-developers.com/showthread.php?t=2512981&highlight=at&t
Now I can see the the tethering tuned on. I can also connect to the wifi. however, it does not connect to internet. I think I am still missing some piece. I cannot post in the thread above as it is developers section. But I am lost, there is no further solution that I could find on forum or google. My mobile data works fine, I can turn on the tehter, I can connect to the hotspot, but I cannot connect to internet. It is a phone issue for sure.
I am not sure what to do in this case. Any help will be greatly appreciated.
Edit: I have tried this as well, but it did not work.

Does anyone think flashing with stock ROM will help? does it delete all system files altogether? But the only stock ROMs available are AT&T, so I do not see it helping much. Any ideas?

If there's a tethering mod for the i337m on 4.3, try using that tethering provision instead. Otherwise, you could try flashing a ROM that uses an i337m base, but you can't flash their stock firmware directly.

I have tried that tethering mod (if that means replacing the tethering.odex file in the system)
I don't know what i337m base ROM is, but if it is installing AT&T stock ROM, then won't I be in same situation again?

I337m is the Canadian S4 model, I'm saying to use a tethering method designed for that (the two you posted were for the Verizion and AT&T but not Canadian) or try a TOM based off the Canadian firmware. That way it'll have the file for your specific carrier tethering already in it.

Not the stock firmware, that won't work. I mean to try and find a ROM based off that firmware/made for i337m.

First of all I appreciate your patience in these replies and helping me out.
Here is my next query.
I found this custom ROM based on i337m
http://forum.xda-developers.com/showthread.php?t=2313469
This post recommended this ROM
http://www.droidviews.com/best-custom-roms-for-att-samsung-galaxy-s4-sgh-i337/
but they also said I need to make sure that the baseband matches. I have MK2. Should I flash that or should I just go ahead and install the ROM as no such info is mentioned in the XDA thread. Also, are there any other changes I should make before installing this new ROM using safestrap?
please let me know

You'll have to look in the All Things MK2 and NB1 thread for install instructions and if it needs a modified updater-script for Safestrap. Also, the latest version is a 4.4.2 ROM so you'll either need to update to KitKat, use the KitKat Magic Toolkit, or use an older version of Goldeneye.
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.

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.
