i can tell you off the bat that going back n forth between mdl n mf9 was a total waste of time. and seeing the process was a waste as well. you want to be on mf9 with hotspot mod. correct? well in the Android development there is a rom called intrinsic. go to there site. download the 7-16-13 file and of course whip your phone before flash n simply flash it. if you want as list of the apps that was taking off n want to put them back on there is a list on their page. this rom comes with the hotspot mod built in. so no need to flash a separate one. i'm on the rom myself. very smooth and hotspot works perfect for me. let me kno if you have trouble with any of this.

HAPPY FLASHING!
[Sprint Samsung Galaxy S 4 Android Development] cruise350:
First off, you should be downloading the hotspot mod from the development section on xda, not qbking's page. Second, you are using the wrong file if its freezing at the sprint screen. If you only rooted mf9 from the update file you are on a stock odexed rom and need to use the mf9 odexed hotspot mod.
[Sprint Samsung Galaxy S 4 Android Development] steveoski111:
I will try the files from the dev section here.I just used qb kings because that is what I used before and it worked great. I just verified what I downloaded and it was mf9 odexed. I'm not sure what the issue was. In the event that it locks up again, is there anyway to not have to flash a different Rom maybe like a safe mode that I can use to restore the files back?

I'm trying to stay on a stock Rom for awhile because once I start flashing I don't stop lol this is why I want to just have the rooted stock Rom with hot spot.

Any ideas on why it would even lock up in the first place? Since I definitely did download the right files unless they ate wrong on qb site.guess that's what o get for not downloading from xda!
[Sprint Samsung Galaxy S 4 Android Development] cruise350:
Do a backup of your system partition in recovery. That way if the upgrade fails, you can restore your system partition and be back up and running quickly. You could do a full backup also, it's good to have a full backup of your phone for emergencies. If you have an external sdcard save it there since a full backup is pretty big.

I did the Odin stock room. Then ota to mf9. I attempted root via video and wouldn't root. Can someone help?
[Sprint Samsung Galaxy S 4 Android Development] spectheintro:
Ok, I can't tell if I'm a retard or what, but I've read the guide 3 or 4 times and I am terribly confused.

I currently have MDL firmware coupled with a rooted stock ROM and TWRP v2.5.0.3 and the Hotspot Mod. Can someone please explain the steps I need to take to update to MF9? I don't need specific guidance (i.e. adb commands or anything) but I honestly have no idea what concrete steps I need to take. What I'm looking for is something like:

1.) Wipe your phone

2.) Use Odin to flash this stock package (link here) which overwrites your recovery

3.) Re-root your phone using any available guide for MF9 rooting

4.) Flash custom recovery of your choosing

5.) Profit

Is this what I need to do? Or is there a way (because I've rooted and have a custom recovery) for me to just update the firmware and then flash any custom ROM without having to lose my custom recovery? any help would be greatly appreciated, because I am a very confused panda.
[Sprint Samsung Galaxy S 4 Android Development] ROMANTiC KiD:
1) factory reset/wipe your phone

2) odin back to mf9 using this link http://xdaforums.com/showthread.php?t=2375523

3)re-root phone with the same way you rooted MDL

4)install custom recovery

5)profit

;) ;P
[Sprint Samsung Galaxy S 4 Android Development] spectheintro:
thanks a ton, man. :) one quick question--do i need to do anything special when wiping my phone, or can I do it any way I please? (i.e. "wipe phone" in custom recovery, "reset phone" in settings, etc)
[Sprint Samsung Galaxy S 4 Android Development] ROMANTiC KiD:
Wipe your phone in custom recovery.

Guys

my nephew has a Sprint S4 MDL that I CF auto root no other change was made to it.

I want to update his phone to MF9.

I am not very familiar with the phone since I don't have one.

I read most of the stuff but I want to make sure i understand and donwload the correct stuff.

I have to flash it back to stock MDL and them update and root correct?

thank you
[Sprint Samsung Galaxy S 4 Android Development] pvinodnayak:
www.sammobile.com has the full stock MF9 firmware, download it and Odin it. Then root again using CF AUTO ROOT.

[Sprint Samsung Galaxy S 4 Android Development] eurominican:
Im quoting this post because its the one that gave me hope. After almost 3 hours of odin saying FAIL when flashing stock firmwares, it turns out my issue was I was using a virtual machine to do it.. -_- On the first try on a regular windows XP desktop it worked!!

The moral of the story is, if you try using Odin to flash and it doesnt work after using several different cables / ROM files and it keeps failing (at different parts of the flashing process), dont keep wasting your time and go do it on a regular windows PC.
[Sprint Samsung Galaxy S 4 Android Development] travanx:
I was not able to get 4G on my phone the other day. So I am going through these steps. Flashed to MDL through Odin from OP, made sure everything said custom in download mode. Took the OTA MF9 update. Rooted, TWRP recovery. Can't wait to drive somewhere that has 4G to see if this now works.

As an edit I am also flashing another S4 at the same time. The MDL would not stick until wiping and flashing the tar 3 times through odin. First time recovery said custom under both. 2nd time binary was official. Third time both said official. Taking the MF9 OTA on 2nd phone and it seems to be working.
[Sprint Samsung Galaxy S 4 Android Development] conflikt:
Is it possible after flashing back to stock MDL to just flash a MF9 odoxed? or must u odin?

[Sprint Samsung Galaxy S 4 Android Development] Chuki82:
Thank you for all the help you provided in the mja rom thread. Now if we can just get a stock kernel with working wifi that would be awesome.

Seems like the latest kt kernel has a little bit of wake up lag. Or it could just be mja. It doesn't seem to be quite as polished as mf9 did.
[Sprint Samsung Galaxy S 4 Android Development] xuser:
Hopefully the MJA modem loosing sound issue will be fixed soon. I'd like to get the modem only, I hear it's a good update.
[Sprint Samsung Galaxy S 4 Android Development] nitty917:
is this any different then the one Sacs released, thanks to both threads. good work guys.
[Sprint Samsung Galaxy S 4 Android Development] Mudavo:
Not sure if I understand. This is a guide for installing a ROM. Cnexus' ROM is full stock. Sacs' is modified and custom. Whichever you prefer can be installed using this guide.

I got a big problem...my phone is stuck at Download Mode, odin says RESET OK!..but my phone still shows "Downloading... Do not turn off target!!" ..is it okay for me to force turn off my phone? I've never been stuck in download mode
[Sprint Samsung Galaxy S 4 Android Development] blarg:
yeah...can't lose sound. I use my S4 as an alarm clock. I had a Droid X with flaky sound for a while...Do not want.
[Sprint Samsung Galaxy S 4 Android Development] Mudavo:
If it says RESET OK then your good. Hold power and when the screen turns off hold volume up to boot into recovery.

Will the KNOX remover script still work IF I do the MJA official update and root it?
[Sprint Samsung Galaxy S 4 Android Development] Mudavo:
Yes. It just removes Knox files from /system
[Sprint Samsung Galaxy S 4 Android Development] swiggs98:
Is an all-in-one without the ROM in the works by chance? Much easier to update non-TW devices this way.

I can't get wifi to work..I followed the steps correctly ..Every thing else works great ..it is possible some 1 can help me
[Sprint Samsung Galaxy S 4 Android Development] JD1zzle:
Up and Running

Everything runs great, thanks tons. Just need to see if the 4-in-1 bootloader mod will be updated to work, as I did like that functionality.

Had a bit of a touch and go moment when it looped at the SGS4 screen for a while and then wouldn't boot into recovery, but I was able to drop Recovery back on with Odin and reflash rom and kernel and it works fine now. All settings and data transferred over properly from Stock Rooted 4.2.2 with Titanium, no problems. Wifi Fix works flawlessly.

Thanks tons!

---------- Post added at 12:09 PM ---------- Previous post was at 12:08 PM ----------

Are you sure you flashed the Wifi Fix properly, as was stated in the instructions? It is a different download off of the page that has the Kernel on it, you need to flash both separately, they are not the same file.
[Sprint Samsung Galaxy S 4 Android Development] opz187:
Hey guys check it out. I never updated to 4.3 cuz of all the issues, but I saw that unknown force updated his modem only.tar today, so I decided to give it a try in Odin. Had some trouble at first, it would pass in Odin, but when it rebooted the first boot would freeze on lock screen and reboot. When it finally got to the OS everything was still MF9. So I odined again, but unchecked auto reboot and f reset time. Then booted into recovery from download mode. Then selected power off from recovery. Finally, I pulled the battery. so next when I booted up, it said Android was updating, success. Checked in about device and voilà, mja baseband and software version on stock mf9. No Knox bootloader, and sound is working. Just thought I'd share my success. Now I'm gonna go play with my n5 seeing as to howi took the sim card from my s4 so I could activate it on sprint haha

Modem has to be Odin and not flashed via recovery??
[Sprint Samsung Galaxy S 4 Android Development] Mudavo:
For now yes.
[Sprint Samsung Galaxy S 4 Android Development] kevinsturf:
So I didn't have access to my PC at the moment and was on my Mac. I used Heimdall to flash the MJA modem. Everything said 100% and device rebooted in and I checked my baseband and to my surprise...MJA!

Question now... I seen from the post that it's supposed to say "Android updating"? Mine didn't say that but I got a message saying "device will reboot now." So I let it do its thing and I'm back in and still MJA :D
[Sprint Samsung Galaxy S 4 Android Development] tiger5969:
Yes this work for me
[Sprint Samsung Galaxy S 4 Android Development] ParkerParker:
well awseome worked great for me and didn't need a battery pull :) Thanks for the write up, glad I waited to update!

Shoot. Did all but the modem being I just moved and my Pc is packed away. Can mobile Odin be used for the modem? If not looks like I'll be pulling the Pc out tomorrow to upgrade the modem. Is the new modem better? I have a tower down near me. Been Down since August supposed to be fixed by the end. Of the month. Drop calls like no other.

This works for me too
[Sprint Samsung Galaxy S 4 Android Development] MENACE_69:
I can also confirm using

unknownforce's updated tar file he posted today, with the help of opz187's way of doing this worked ! I'm on sac's v8 4.2 TouchWiz rom Rockin the MJA modem, without having to update to 4.3 which I was just about to do tonight. until I stumbled upon opz187's success in this thread.

Thanks, both of you

How are you getting the wifi fix to take? After flashing everything boots but then the second page the wifi will not tun on.
[Sprint Samsung Galaxy S 4 Android Development] Mudavo:
Try right click Odin exe and click Run as administrator.
[Sprint Samsung Galaxy S 4 Android Development] opz187:
You can't reboot right into the system, to get it to stick, in Odin load the mja modem in phone Mode below pda, and make sure you uncheck auto reboot and f reset time. Then when Odin says pass, hold the power button and volume up until it boots into recovery. from there on the reboot menu select power off. Then pull the battery for good measure. Now when you power on the mja firmware should have stuck. You could honestly probably pull the battery directly from download mode, but I haven't done that so I can't be sure. To be safe you should probably do it the way we know works right now

---------- Post added at 01:22 AM ---------- Previous post was at 01:14 AM ----------

No problem buddy, it's good to hear it's working for others. No need to thank me tho, all the credit goes to mudavo for the methods and research, and definitely unkownforce for sifting thru the 4.3 update and somehow extracting the formate even tho the modem was patched.
[Sprint Samsung Galaxy S 4 Android Development] ParkerParker:
I didn't pull the battery, after flash I just held the power button, then a pic of a green battery came up, held power again and it booted saying something about update, and all is good thanks for testing man!
[Sprint Samsung Galaxy S 4 Android Development] vat829:
I did exactly that but it didn't stick. Maybe I'll try to right click and run as administrator
[Sprint Samsung Galaxy S 4 Android Development] beserker15:
Make sure you are not going to Download mode by using the power menu in your rom. Fully power off the phone, then use Power + Home + Vol Down. Then do as the instructions say. Battery pull isn't even needed. I powered off after entering recovery, then powered back on, works just fine!

[Sprint Samsung Galaxy S 4 Android Development] t2noob:
so I had something weird happen after flashing the mja modem....after it booted up and everything it showed the mja stuck and everything but then i had a notification pop up saying the phone was going to reboot.... couldn't deny it just gave me the option of ok....and i couldn't back out or anything... so im wondering if anyone else has gotten this.... and after that it rebooted and said android had finilized the update...which im guessing was the modem...but have no idea what it was...
[Sprint Samsung Galaxy S 4 Android Development] leaderbuilder:
I think that this step - NOT using any other method (Apps like quickboot, power toggles on your ROM etc.) to power off your phone completely is vitally important. [It was for me. :) ] Then enter Download Mode manually - Power + Home + Vol Down then up to confirm is the key to getting the rest of the instructions to work.
[Sprint Samsung Galaxy S 4 Android Development] ricohz:
I just updated and i just let odin reboot and it stuck for me thanks every one
[Sprint Samsung Galaxy S 4 Android Development] travisw0204:
[MENTION=507298]opt[/MENTION]z187, Mudavo and Unknown you guys rock. All is well over here. I did get nervous at first because it just showed my logo screen for about 4 minutes and then the Rom booted. However, I don't have WiFi anymore. I tried the WiFi fix and it isn't taking so I'm just gonna flash Ktoonez kernel and see if that fixes it. I'm still on Sacs 4.2.2 V8 Rom waiting until he uploads v3 for 4.3.
[Sprint Samsung Galaxy S 4 Android Development] Mudavo:
Thanks for all the feedback. OP MJA modem flash instructions updated with new findings.
[Sprint Samsung Galaxy S 4 Android Development] rickpub:
I was going to try mobile odin. Installed it and it warned me that it did not support 4.3... you are able to continue but I decided not to try it... didn't want to possibly brick my phone. May read the mobile odin thread some but seems easier and safer to just update using odin on the pic
[Sprint Samsung Galaxy S 4 Android Development] travisw0204:
Update: Ktoonez 4.2.2 kernel fixed Wifi and Hotspot not working. Thanks again guys. Awesome work as usual.

**For those that do flash this and are running Sacs v8 rom, it will hang on the logo screen for about 5-8 minutes. Just let it do its thing. I followed the Op to the T and got stuck on a logo screen. I thought I was screwed so I immediately tried to get into my recovery to no avail. I removed the battery and put it back in and, after the 4th attempt, was able to boot into recovery. I restored a nandroid and when I rebooted I was still getting a logo screen. At that point I just left it alone. Eventually, it booted back up with no issues. I guess the modem .tar file for some reason breaks a portion of the boot animation but you aren't bricked so don't panic. Once booted back up, WiFi won't work so you have to download ktoonz 4.2.2 kernel. Once flashed, you will see your boot animation return to normal and all will be working again.
[Sprint Samsung Galaxy S 4 Android Development] Memphisjojo:
So with the no Knox bootloader....if we go to mja can we go back to mf9...

Would there be a reason to?
[Sprint Samsung Galaxy S 4 Android Development] Mudavo:
Yes you can switch between mja and mf9 modems. Why? ROM compatibility issues. Also because I don't like being tied down.

worked for me too, but on stock rooted MF9, broke wifi.

Whats the difference between mja and Mf9 modem
[Sprint Samsung Galaxy S 4 Android Development] ParkerParker:
I never had this happen, but I flashed tar with KT Kernel already installed prior to modem upgrade, I've rebooted quit a few times messing with Xposed, went to AOSP and came back to sacs with no issues, wonder if it's best to have kt already installed prior to modem flash?
[Sprint Samsung Galaxy S 4 Android Development] xuser:
The update to the modem only install seems promising. It seems to have fixed the sound and dial freeze issues. I'm just wondering if the WiFi fix can be flashed to any ROM or kernel? As of now it seems to only work with stock ROM and KT kernel. I'm running a MIUI ROM for now till a stable KK comes along or Sacs 4.3 ROM comes up to speed. So many good choices, I just don't want to limit myself with a modem that won't allow a "downgrade", or limit my choice of ROM and or kernel.
[Sprint Samsung Galaxy S 4 Android Development] Mudavo:
You can downgrade the MJA modem. Its the MJA bootloader that can't be downgraded.

So if im on the mja bootloader I can switch back to mf9 modem

★☆TEAM VeNuM☆★
[Sprint Samsung Galaxy S 4 Android Development] xuser:
I'm aware the firmware is the issue on downgrading the modem. My question was more about being limited (for now) to a Stock ROM and KT kernel with the MJA modem, in regards to the WiFi fix.
[Sprint Samsung Galaxy S 4 Android Development] milli5410:
so do we have to install the mja modum
[Sprint Samsung Galaxy S 4 Android Development] jdmboy1188:
MJA

So im a little confused im running Sac custom rom 4.3 with mf9 what would be the benefits of upgrading to MJA is it major benefits or should i not risk it?
[Sprint Samsung Galaxy S 4 Android Development] xuser:
There are benefits in upgrading the MJA modem, that's the radio that gets you service. I've read there is better reception and call quality. Though if you want to downgrade the modem later for whatever reason DON'T INSTALL THE MJA FIRMWARE. Just install the MJA modem. See instructions in OP.

So just to double check once i have the recovery installed and rom do i just flash the modem update through recovery?

I read the post 3 times and i dont see the step when i flash the modem?

EDIT: i meant through odin since its a tar file?
[Sprint Samsung Galaxy S 4 Android Development] travisw0204:
Yeah reboot to download mode with the Power off by holding Vol down + Power button. Once you see Andy the Android then press the Vol up button to enter download mode. Then open Odin, uncheck Reboot and F Reset. Flash the .tar file using the Phone selection. Once it says Pass, power off the phone and pull the battery out. Then put the battery back in and reboot. You should be good to go.
