MF3 S4 question *noob alert*

So I bought a S4 yesterday on Craigslist and its on 4.3. I was looking around and I saw there is a MF3 firmware type crap out there and I was wondering could answer my question on what that is and if I have the firmware because I am trying to root my s4

You need to do a lot of reading. Look for the pinned threads in the general forum. Also, on your phone got to settings, about phone and look at the last three characters of your baseband. That will tell you for firmware version.
Don't try to root it into you do all of this

What are you on? You can still root with vroot but be aware vroot has been stated as malicious. BUT BEFORE YOU DO ANYTHING MAKE SURE YOU READ, FAMILARIZE YOURSELF WITH THE PHONE THAN RE-READ SINCE YOUR A NEWB!

This is most likely why the original owner sold it. You won't be able to install custom roms until a exploit is found or Safestrap gets 4.3 support. As for root there is a few methods but they are untrustworthy and not allowed on XDA. Best to what for a safe root method...

[Q] how to go from JB to KK? Very confused.

Hi all, Can anyone point me in the right direction? I am on Viper Rom on a SM-N900T 4.3, AND I want to try a KIT KAT rom, but I believe I need to go back to a stock rom first? So I have a few questions...I just got the phone and have been reading alot on it, but to me it gets confusing, and I dont want to brick the phone. I am rooted as well.
Where can I get the stock rom?
I have TWRP version 2.6.3.8 will this work to flash the stock KIT-KAT rom?
I am on BASEBAND N900TUVUBMI7
I read somewhere in XDA that if you go to KITKAT you can't go back to Jellybean?
Just a little confused here, and all the reading just confuses me with all the different models, roms, kernels, etc etc...
Thanks in Advance for the help, Larry

ODIN.... If you use 3.09 you put the full rom in AP, if you use 3.07 or lower put it in PDA. Make sure you have it unzipped to an .MD5 or .tar file...

You said you're on the N900T. There's a forum for that.

Ok, So here is what I did:
Downloaded Polish stock rom to work with tmobile.
Started ODIN. no blue box
Put phone in Download mode and plugged in to PC
Odin box turned Blue
selected AP
Browsed to the Polish stock tar file and selected it.
Waited about 30 seconds until it showed in the list next to the AP buttin in ODIN
Clicked Start
Waited about 30 seconds and then the box said Fail..
In ODIN I noticed it said something like NAND WRITE FAIl(auth) or something like that.
Im not at home so I cant be sure exactly the message details, but it sounds like I need to re-partition or something?...maybe load a different recovery?
Im using TWRP 3.6.7? I believe the number is, and I am currently on 4.3 ROOTED ( knox 0x1)
Can someone clarify this for me? I get confused because there are so many ways to do this, and different variables.
Thank you so much!!!!!!

Did you try it with the PIT?
EDIT: Just noticed you have a N900T, why are using the Polish stock? You need to use the N900T stock which you can get from Sammobile. I think you've come to wrong place buddy as international firmware won't work with the US T-Mobile version.

Thank you!!..I looked on Sam mobile but don't see a us version listed....do I use the UK version?

And here's the URL for 4.4.2 - http://www.sammobile.com/firmwares/3/?download=26282
You may need a PIT file but I'm not sure about this particular version of the device. Anyway, good luck and happy upgrading.

XSA ROM

Hey guys.
Quick one, is the XSA rom you can get from samobile the stock Samsung rom? As in not telstra or Optus? Like you would get if you bought unbranded from a Samsung store?
Thanks guys. Only reason I ask is that I'm trying to figure out if my Optus firmware is crappy, I'd guess it is but just need to see before I can't take it back.
Thanks again.

Search all the different AU(?) Firmwares and see, its possible XSA is the unbranded one - although saying that, I think sammobile says if its unbranded.
Sent from my CM11 Kitkat powered N9005

XSA is the unbranded one...

Thanks guys.
So I shouldn't have any trouble with that yeah?
It's the same build number as I have now so that should flash fine, without triggering Knox?
Thanks.

Yup no Knox worries
Sent from my CM11 Kitkat powered N9005

Thanks again guys. Might do that in the next day and see if it's this crappy rom.
Help me understand this note 3 Knox business. So, I've had nexuses and other Samsung's and I've never had the thing where I couldn't use a previous version of Android if I updated.
So is it just the bootloader we're talking about? If I updated to 4.4.2, I couldn't use anything older than that? Even just the rom?
So how would I even get a 4.4.2 rom if say the roms didn't include the bootloader? And if I did get a bootloader, is the right one? Haha.
Sorry to ask so much, just things seem different with this particular phone and the current versions of Android.
Maybe it's just the bootloader and you can't go and use an older version of Android if that's been flashed.
Couldn't you flash a stock 4.3 official rom if you wanted to go back?
Thanks in advance.

If you flash a stock KK rom it updates the bootloader. If you get the broken up KK polish rom and don't update the bootloader then KK doesn't load.
Once you update to the latest KK bootloader you CAN'T go back to JB... You will trip Knox warranty void if you try...

Argh I see.
So basically it's the bootloader. But if you root, flash custom recovery and or rom, that's going to trip knox anyway isn't it? So if you did use a earlier version of Android, you still can, it will just trip knox?
Tripping knox doesn't make your phone unusable does it? I'm sure there will be some sort of triangle away or similar that will get rid of it. What if you flash a clean bootloader? Would that clear knox? I wonder where the knox counter info is stored and if it's accessible...
Geez, making myself sound like a noob here haha. I swear I'm an experienced flasher haha.
Just making sure I understand this before I do anything. Seems a little different than normal. Everyone should understand this stuff before they do anything. Haha.
Thanks again.

Bootloader differences

Just a quick one guys, is the bootloader any different in the firmware builds of 4.4.2? As in, NB3 or NA7 etc etc? Is it really worth flashing a later firmware to get the 'latest' bootloader? In my knowledge, I doubt there much different as it has not much of a bearing in the firmware itself, I've been told anyway.
Thanks in advance!

As far as I know, there is no difference in the bootloader between the KK builds -- or if there is, they seem to be fully compatible.

Thanks mate. Yeah, I didn't think so. What are you running at the moment? Did you flash KK firmware and flash custom?
Thanks again.

I think you can download these versions, extract it and binary compare the files inside to know if they are the same or different.

Flashing bootloaders is a risky business... These little puppies will almost always give you an expensive paperweight if something goes wrong during the flash...
Custom rom with NB3 bootloader... Like the old Androidnow rom, NC2 but developement has stopped and also Assassin rom, waiting fop the V3 with the latest base....
Both those roms have good battery life (depending on use of course) but my screen on time is generally around 4 - 5 hours with around 70% battery left....

That's insane. Haha. I'm just sick of waiting for Samsung to do there business in Australia. This is ridiculous. I've never had a device this long without rooting... It feels, unnatural haha. I'm thinking xnote, crash, bobcat it assassins.

Both... However in the last few days this has increased somewhat due to me turning off my mobile data cause I went over my limit... Bloody google+ and it's update of pictures and videos. There's a reason I use a 64gb sd card....

Well, I flashed the Netherlands latest firmware and working like a charm. Even kept my Data partition haha.
So bootloader is 4.4.2 now. Trying to find a way to flash twrp without tripping Knox. Don't think it's possible. I've read that the kernel and the recovery are the parts that trigger Knox.
I noticed that there is an option to flash update zips through stock recovery. Could this be a way to flash a rooted custom rom with stock kernel and not trigger Knox?
Thanks again.

ND3 has a locked bootloader apparently, that makes it impossible to downgrade to earlier KK builds.

No way to flash a custom kernel or recovery and keep Knox. Also no way to root on 4.4.2 without tripping knox, if you had rooted on 4.3 and kept root while upgrading to 4.4.2 you could have used MO (Mobile Odin) to flash roms.

[Q] GALAXY S4 ATnT 5.0.1 OFFICIAL NEED HELP HERE!

My playstore not working said. " cant initialize...."
I know the cause of this is the freedom. I used freedom when im in kitkat official. Im also rooted that time. Then i forgot to delete the "host" file before updating. Now my "at&t galaxy s4 is 5.0
1 official" can someone help me root this device pls. To fix this problem ? Or any fix/method to this problem without root ?
I also dont know what is lock and unlock bootloader, even how to check if i have lock or unlock bootloader. What does it mean if i have lock and unlock bootloader
Note: my galaxy s4 is at&t 5.0.1 not rooted.
My galaxy s4 at&t can read any sim card because its already factory unlocked.

First, freedom is warez. DO NOT USE IT. To get you're phone working properly again you'll most likely need to flash the nb1 firmware in Odin. You can then work on rooting your device and getting back to 5.x. But you'll have to read this very carefully first, http://forum.xda-developers.com/showthread.php?p=53758227

All at&t i337's have a locked bootloader. So don't worry about that. Carefully read the link I gave you. Yes it's long and yes it's going to take a lot of reading and re-reading before it makes sense. And yes you can downgrade to kitkat, nb1, and yes you can have root on 5.0. Look at how to flash nb1 in Odin, how to update to nc1 and root, and how to keep root to oc3, 5.0.

The people who contribute here donate their time to the forums. Usually, they do it because they like to help others. For many it is like a hobby.
However, there is already a lot of information collected here on the forums. Most people don't really enjoy saying the same things over and over. And besides, it is not really very polite to ask someone hold your hand, when you can find the information and process it yourself.
Most people here would say, if you can't understand the directions, then you shouldn't probably be trying to modify your phone. So, to re-iterate what jd said, read the instructions, read them again, and again if necessary. Only proceed when you understand what you are doing. If something doesn't make sense to you, ask a specific question and someone will be happy to explain.

You should flash nb1 using desktop Odin. This will return your phone to fully stock I337UCUFNB1 which is KitKat 4.4.2.
You may also want to read through this thread several times.

Is the nb1 is universal ? I mean, how can i know if this fits in my device ? I337 att
