Is it possible to flash MJ6 modem on Canadian SGH-i337m? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hi, I was wondering if there is a way to install this Modem on my Canadian S4. Without it, turning off the screen when Running any 4.3 TW ROM will make the phone too loose signal. When using Odin, it fails and nothing get installed.
Thanks!

First, this question should be asked in either the Q&A section or the specific thread. Second, from what I read someone already tried and even posted in the thread and it didn't work.

[Q] Noob here, Help Needed (what's new)

Hello,
First off I am very new to this. I always try to be as careful as possible and do as much research as I can. I follow all the steps as directed and ask questions ahead of time before screwing things up.
My problem now is I accepted an OTA update to 4.3 from what I thought was a stock 4.2.2. Apparently I was wrong and the superUSER app was still installed on my phone. I no longer have the ability to use my WiFi- (I switch the toggle and it just stays off) I have tried to reset and restore. I have tried to delete all data and re-install. I have tried everything I'm comfortable with at this point. I dont know if I should try using ODIN to flash stock since I probably have a knox bootlocker and dont want to do more damage. I am posting photos because I noticed my naseband and my build number don't match up. I am afraid im stuck in between 4.2.2 and 4.3. I would greatly appreciate any advice or even a push in the right direction. I have been searching trying to find a solution for over a month and the most I can get is... "your an idiot, dont update OTA while rooted, etc etc" Hindsight is 20/20. Thank you again for your time.

I am not an expert but from what Im seeing your on a 4.3 rom but the modem did not update. Your modem is still mf9. I would flash a 4.2 rom and go from there. I don't want to give the wrong info hopefully someone can chime in that knows more than me.

Yeah that is what I was noticing as well. I have soft bricked my phone twice now trying to use odin and going back to a stock 4.2. The flash says fail everytime. I am wondering if KNOX is blocking ODIN from flashing the new ROM. Thanks for your quick response and I guess this means I am on the right path. Now I just need to find a way to flash a stock 4.2 on my fluster clucked half 4.2 half 4.3 phone.
I do know that once you're on MJA there's no going backwards. Try odining the modem. Make sure you turn your phone off...then boot to DL mode. Don't just boot to DL mode seems to work better that way.

I would suggest first trying to reinstall your mf9 modem via odin , if that doesn't work I'd try to install the mja modem via odin. You can find the links to files here http://forum.xda-developers.com/showpost.php?p=42954149&postcount=2
And a thread about a similar issue so you can get a better idea of what you need to do.

[Q] Trying to downgrade to 4.2.2 from 4.4.2

SPH-L720
MF9
Ok, you must be wondering why the heck anyone would want to downgrade from 4.4.2. Well I had one noob moment and a couple of unfortunate coincidences. I haphazardly flashed a rom for an I9505g onto my phone. Luckly I can still boot up and connect to my wifi. If I turn the airplane mode off then the phone goes haywire. Im sure that isnt fixable.
My difficulty is finding a stock 4.2.2 ROM to flash.
I would just flash the recovery i have, but, it somehow is corrupt and sends my phone into a bootloop so i have to reflash the 4.4.2 again to get anything to work. Really, i think all i need is a link to get me going in the right direction for the files i need. If anyone could hook me up i'd really appreciate it.

No WiFi access via hotspot on Rooted AT&T S4

Ok, thanks to k1mu's guide here
http://forum.xda-developers.com/showthread.php?t=2565758
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.

[Q] Galaxy S4 GT-i9505 no updates & other issue

I have had my Galaxy S4 GT-i9505 for nearly a year now, it currently runs Android 4.3 and I have been trying to update it to KitKat version but it seems impossible. I have tried to search for updates using Kies and using Software update in Settings -> About Device, but it always tell me "The latest updates have already been installed", even though there is a newer update available. Any ideas?
Also: When choosing WDCMA Network Mode in Network Settings, my phone seems to weirdly to go no signal. It would function normally when the screen is on but as soon as I press the lock button, it loses signal and I can't use the phone's network. GSM works just fine though, but the speed I get with GSM is close to zero. Any idea why this would occur?

Flashing a custom modem fixed the internet issue!
Your current firmware is here. Install through Odin to update, but keep in mind you will have to reinstall everything afterward. Note that installing a custom recovery will prevent OTA updates from functioning so if you have a custom recovery installed, use Odin to flash the stock recovery, then try updating.

Your warranty gets void okay?
So if you are really willing to flash a Custom Rom, TWRP/CWM Recovery and a Custom Kernel
Its not going to be so hard actually.
The MOST IMPORTANT part that you will need to do before flashing a custom rom is to ROOT AND FLASH A CUSTOM RECOVER SUCH AS TWRP
Auto-Root from Chainfire which i used also.
http://forum.xda-developers.com/showthread.php?t=2219803
that doesnt include a custom recovery. you need to download and flash it for yourself over odin. go search it since i forgot where to find it. lol but a little re-search you can find it easily.
I would recommend you these 3 roms since i use them a lot.

[Q] I337UCUFNJ4 AT&T Galaxy S4 4.4.4 only download mode

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.

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.
