MDC was the stock version that shipped with the phone and MDL is the update that was pushed out OTA.
I do not believe there is currently a sticky that explains the differences. Here are the main ones though from what I have gathered:
- MDL updated the radio firmware. I haven't experienced any enhanced reception but mine was already good to start with.
- Many reported that MDL decreased the lag users were reporting in MDC.
- MDL installed a new kernel that initially prevented root. However, thanks to the great devolopers on this site, that is no longer an issue and the MDL kernel is now easily rootable (see the developer's forum for instructions if you need it).

MDL for me definitely decreased some of the lag. It also fixed an issue I was having with blacks having a brown tint. The blacks are a lot deeper now.

[Request]I-337 AMDL flashable modem -Please, pretty please

There are a few of us that did not update OTA and now when we have AMDB baseband. This is causing issues with newer ROMS. I know this is something that done talented folks here can do easily. I can't so please, you will earn my thanks and that of many others.
I admit we could ODIN back to stock AMDL but this would save a lot of hassle.
Thank you

There are no disadvantages to installing the AMDL OTA.
No, but it would be nice to have some flashable zip modems. The devs will eventually provide them.

Compared to flashing just the modem, it's two additional long steps.

I hope you're right, haven't seen any interest in it thus far.
Anyone know if it is possible to flash a T mobile Variant Modem on the device ?
Or the whole ODIN STOCK Firmware from the M919 ? ? ?
Reason is cuz i have tmobile and i dont want it to run on the 1900 Band .. .

Should I even bother trying to upgrade to MF3?

I keep reading about the problems people are having with flashing to MF3 on their rooted S4As but I can't find anything on what you get with MF3. Can someone enlighten me on its new features or post a link that lists what it does?

Just install one of the stockish MF3 based ROMs or International Update based ROMs from the development section and you will have the best of both worlds. You will get any enhancements from the update (if there really is any) and still be able to keep custom recovery and use other ROMs / themes / etc.
If you update to MF3 (OTA) you will lose the ability for custom recoveries and ROMs.

I don't think the active can run a custom recovery or other roms.

I was able to install it pretty easily by unfreeze some apps. Reinstalled activeroot afterwards and refroze and am good to go.
I still can't tell any difference and am gonna wait before I upgrade my wife's s4.

Didn't realize this was for the active. Nit sure what mf3 brings for that variant. XDA should seriously create a sub-forum for this variant. It not the same specs, software, the roms are not cross compatible, whats the point?

so then they didn't have the MDL stutter/lag we had when the S4 first came out
Well, I upgraded something for 18MB via software update. In the active master thread, it is being referred to as mf3.

I agree with that Pat MOD???
It clutters thread, not in a negative way against the Active, just too much to watch for when trying to help people. Active owners want it too--
Not sure why it isn't

The New I337UCUEMJ6 Seems Fine

Since my S4 is bricked and I have no MF3 Odin to save it, I put on the Beta I337UCUEMJ6. It works fine. Now my phone is alive. I'm going to keep this one at stock.
I've not noticed any big difference vs. the MF3.
The official MJ6 should come soon.
As if this morning there are mf3 files for Odin. http://forum.xda-developers.com/showthread.php?p=46943588
That's great news but people on mj6 can't go back.

You are correct. But for those who are semi-bricked they have another option other than mj6, or best buy
I could not find MF3 Odin files. That is why I put on the MJ6. This phone will run stock only. I just want it to work....
Can anyone confirm whether this gets rid of the talk back issues running a pebble watch

What ROM is everyone using right now

Just curious to hear what people are currently running on their S4. I just noticed it looks like 4.3 update is finally available for ATT so might just flash that for now.

Questions go in the Q&A section.
Using stock 4.3 mk2.

Is mk2 good? I thought I read something negative about it somewhere... And was that the one where once you update to that you can't revert?

You can't revert once you're past MF3. MK2 has been working just fine for me, the only negatives are you don't get ROMs or recovery, neither TWRP/CWM or SafeStrap. Also, they removed the network data toggle which does suck.
You mean from the drop down where you can just flick it on/off? I don't use that one too much but I know what you mean...hate when I lose toggles I was using before.
But No ROMs or recovery?? Is that just cause it's pretty new? Seems surprising

I'm using Gummy 4.4.2 and it's working awesome!
Well, this thread is being closed as "everyone" is a subjective term, there are plenty of ROMS for many users that many are using.
This question can only be answered by the individual user? Try all the roms over in the development threads - that is why we are here, and the fun part of the journey.

Have you checked Device Administrators in Security to see if anything is there that shouldn't be?

Are you rooted?
If so, what rom are you running?
This is the exact issue the UnKnownforce is trying to fix in his thread.
Go HERE and search the thread for lockscreen. You'll find many posts concerning this issue. There is no 100% fix yet. Works fine for some and not for others.

That's what I'm guessing he did. Someone said that if you flash with cwm not Philz or Twrp that it works.

Well that makes absolutely no sense. You took the OTA then rooted and flashed the NAE modem??? If you took the OTA why would you have to flash the NAE modem. Something is fishy here. Are you on the NAE upgrade or are you a piece meal install with mismatched bootloader, modem, and software. If you are on stock NAE then the lock screen should work as mine works with all options. If you are on a custom rom, that is where the problem is. Post a screenshot of your about phone info page or list the specifics of what you have so we can further help you.
Yea i took the Ota everything was nae but my baseband then I flashed the nea modem is

You might be screwed until the stock tar comes out. If your baseband hadn't changed with the ota, then the update didn't complete. You may still be on the mk2 bootloader. There is suppose to be an app that can tell you what bootloader your on, but I don't know what it is called. You can try to Odin the mk2 tar file. If it completes your golden and then can redo the update. If it fails then you have the NAE bootloader. you can try installing a custom kernel to get wifi back, or see if you can find a copy of the stock NAE kernel.
