MDC/MF9 Bootloader and updating to NAE - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Hello everyone! I have been checking this forum for quite some time now and I wanted to update my phone to NAE. Right now I am on MDC bootloader and I wanted to know if there is any advantage in updating to MF9. Should I leave it on MDC?
I am using a MJA Rom with MDC bootloader.
Thanks in advance and great community btw!

Thanks bro, I actually read all that and downloaded everything I need to update to NAE. I just wanted to know if there was any difference or benefits between MDC and MF9 bootloaders before updating.

Same boat here. I'm actually on mf9 but wanted to make sure before I do anything. I can keep mf9 bl and then update everything else. I don't want to assume there's no downfall to doing this as well... You know the saying about assuming and all that. Otherwise I'd just as well stay on mf9 everything which is working perfectly.

My bootloader = MF9
Baseband = NAE
ROM/PDA = MK2
I'm on an MF9 bootloader with NAE baseband/modem and run some 4.4.x AOSP/CM ROMs and have tried a couple TW 4.4s too. Usually try and give them a good workout, but just find, for me only mind you, that they are not ready for prime time.
The nature of my phone use takes me back to my rocksolid MK2 based TW ROM for daily driver.
If you follow the OPs instuctions AND read through the entire follow-up posts for a particular ROM you will get an uderstanding of issues and fixes or resolutions. I think it's completely inane to flash something, then complain about an issue that has been already brought up multiple times.
If you try something and KNOW what you're getting into you might find something that works for you.
Good luck.

[Q] I think I hosed myself

I activated my S4, and I 'thought' I had taken the MDL update before I rooted, apparently not. My WIFI will not come on and I get the nag notice every time I try to open. Upon looking at my About Device screen I see that that my baseband version is L720VPUAMDC but my Build number shows JDQ39.L720VPUAMDL.
Used CF-Root and it seems to be holding according to Root Checker. I am currently downloading the stock MDC restore in an attempt to correct this problem. My hopes is a flash back to stock and starting from scratch will fix my woes. Am I wrong?
No custom recovery installed.I did a factory reset when I saw things were going bad. Any help will be greatly appreciated.

I would recommend flashing the stock MDC firmware and starting from there.
Here is a link to "[HOW TO]Install Latest Stock MDL Firmware & Modem w/Custom Recovery & Root"

The first 2 links on that page are to Odin and the Stock MDC firmware.
There are step by step instructions listed on how you will use Odin to flash the Stock MDC firmware.
I am currently downloading the SPH-L720_MDC_STOCK_RESTORE.exe file I found from another link. Do you think that will pose a problem? I would really hate to stop my current download and start all over.

If it is the one from here http://www.sxtpdevelopers.com/showthread.php?t=231 that will be fine. You will need to follow the instructions in that link.

MJA update without bootloader

I am trying to decide whether or not it is worth the effort to update to MJA without updating the bootloader per http://forum.xda-developers.com/showthread.php?t=2277480. I am now running 4.2.2 pretty much stock with root. I would like to run the same way on MJA, but don't want to have the wifi problem and would like the option of running stock kernel. I have not been able to find what is causing the wifi problem. Are people taking the OTA experiencing the wifi problem? If I were to install the update as described in the link above without the KT kernel, what is the difference between that and the OTA, other than the bootloader? Why would it experience the wifi problem and not the OTA?
From what I have read you should be fine. I am trying to make the same decision. I'm basically stock mf9 rooted and tweaked.
My understanding is that we could Odin the mja with root and be like we are currently with all the new goodness. The disadvantage, if it is one, is that we could not go back to a mf9 rom due to now having the mja bootloader. I am trying to wait for one of these amazing devs to get a tar or zip together that would be a one flash setup allowing us have all of the new stuff minus the mja bootloader. I don't think I would ever go backwards but I don't want to destroy that option. I probably won't be able to wait much longer and wind up jumping through all the hoops to get the mja modem, 4.3, and keep the mf9 bootloader.
I am in no way a developer and please someone correct me if I am mistaken. I hope this helps you in some way.

I just did what you're thinking about doing and my experience has been great. I have the full MJA with out the bootloader. The phone runs stable and fast. No Wifi issues, LTE works, and clear phone calls.
It was more time-consuming than flashing a tar but I'm liking MJA a lot right now.

The KT kernel with the wifi fix. I didn't mess with the KTweaker settings.
I'm currently running MDC rooted stock with stock kernal. if i update using the thread posted by the OP. Will i be using MJA or MF9 bootloader...i've read throught the instructions and don't see anything about flashing the MF9 bootloader, or would that be the step which removes Knox

Before I started on the guide, I was on stock, rooted MF9. After the guide, I was MJA everything except the bootloader, which is MF9. As a result, Knox isn't triggered.
Since you're currently on MDC, perhaps you should start by flashing the OEM MF9 tar first through PC Odin.

damn...another slow 1GB+ download

MF9 (debloated and deodexed)

is there one floating around?
i looked but didnt see one
Most Roms are MJA or MK2 now as devs always stay on top of the latest updates. Download stock rooted MF9 and debloat it yourself. I can't remember which ROM might still be on MF9,

i have done the domestic lock so i thought it was good to stay on mf9 with mdc modem. thought about flashing modem back to mf9 as the modem will still stay unlocked but if i goto mja or mk2 i think i loose the unlock carrier mod and plus how do you all deal with knox?
figured most people would still want to stay on a firmware you could downgrade when you want and flash what you want without to much trouble
you think i should stay on mf9 considering my needs or is mja and mk2 ok to upgrade to now?

Last ditch attempt at help

Is there a single ROM out there for someone who went from MDL(I am pretty sure), who then ODIN'd MF9 way back last year...who then ODIN'd NAE MODEM ONLY, and is able to use their phone or camera, on ANY ROM whatsoever?
ive tried Negalite and SACS...using philz and twrp respectively, full wipes and all...roms install, some better than others...but on neither can I use phone or camera...and in 12 hours I am going to be halfway across the ocean
if anyone who knows of a similar situation, and has an idea for a rom that I can use while currently on MF9 bootloader, but NAE modem...pls help
thanks
Youll have a wayyyy easier time just Odining a full NAE tar..

okay...but my firmware and radio both say nae...whats a full nae tar gonna change?
That's the current version of the official ROM.
Sorry i meant MF9. Since your on MF9 bootloader than you should be able to flash the MF9 tar right? This way your at least back to a normally functioning firmware. Then just flash your favorite rom. I'm not sure about your specific situation. Its a little hectic. Lol but this would be my best guess and probably correct. Lol this way you'll at least have a funtioning device.. right?

true...so odin flash an mf9, like i was originally on, then find another rom thats working on mf9? suggestions? i loved sacs and negalite, but i believe ive got to be nae for those....
Im sure thats not a problem. NAE is simply the baseband/bootloader. This is not affected by rom.

You could try and flash stick rooted nae ROM and if that works for you then dirty flash nega or sacs.

Going back to stock?

Ok, I have been running an OLD version of SACs custom ROM for a while (Pre Kitkat I think).
I am considering going back to stock Rooted with the Hotspot mod only.
I've been out of the "flashing" scene for a while, so what's the easiest way to go back to current stock w/ rooted & hotspot mod? If you could point me in the right direction, I would appreciate it!
1. Please don't post questions in the development forum.
2. Find Unknownforce's stock rooted NAE thread.
3. Read and follow his directions.

Ahh... Sorry. I was looking at this forum and the Q&A forum at the same time. Thought I was posting in there.
Thanks, I'll look up his.
Been reading different threads. So if I just flash i Rooted NAE ROM I should be ok? I just want to make sure since I am coming from an OLD version of SACS.

You'll probably have to Odin the NAE modem as well. Somewhere in unknown's thread are the instructions to do and keep a pre Knox bootloader
Ok, 1 more question...
If I want to go back to complete stock from the old SACS Rom...
Could I just flash a stock MDL to my phone and then tell the phone to update it's self and let it OTA update to current version?
Would there possible be any problems with that?
Just curious as I have an old stock MDL already on my computer from when I was flash long ago.
I know this way I would have KNOX but I honestly don't really care too much.
That will take a bit, but will work for sure.

You should not do this! If you have a newer bootloader than the MDL install will fail. All you need to do is download the full NAE tar file and install it. You will be updated in one step and you won't lose data. you can get the full NAE tar from here: http://forum.xda-developers.com/showthread.php?t=2663619
