First of all, love your post! :good:
Do you know if you have the Knox bootloader? You can check by booting into download mode, if there is a line with Knox void 0x0, then you will do and unfortunately you can't download using official firmware.
If you root/flash custom recovery you can downgrade using custom ROMs but you will void the knox warranty.
Are you experiencing problems or having any particular issues with 4.3? Why do you want to downgrade?
First, thank you my brother because you're keen to help others.
My problem with the Kit Kat is root. Because, after the installation of root indicates that the case of Device custom, but some applications need Root do not to operate efficiently.

Yes the security Samsung introduced with Knox caused a lot of issues for some people. Luckily I am still on the old (MGA) pre-knox bootloader, but running a rooted stock based 4.4.2 ROM and can go back to official 4.2.2 if need be. So it really just depends on whether you value the knox warranty or prefer just to go ahead and root and enjoy the features that come with it.

1. I'm still on 4.3, My baseband is N900TUVUBM17, I would like to root WITHOUT tripping Knox.. Is this at all possible at this juncture? If so, what method should work? (I can follow directions, I just need confirmation)
2. I need 4.3 or 4.4 stock for when I eventually turn this phone back in for the JUMP program to get the Note 4, is there a link somewhere?
3. Are most ROMs for the Note 3, 4.3? And if there are 4.4 ROMs, can I flash those if I root my phone on 4.3? I'm interested in SlimKat mostly with Lean Kernel.
4. I heard that flashing a kernel or ROM will trip Knox, so how does one go about doing any of this without tripping it?
5. I thought t-mobile had a flash counter when you turn your phone in (different from Knox), is that true? And can it be reset? If so how?
I'm not new to rooting, and I have read these forms before making this topic. I just need mostly a confirmation on what has worked for people with the same baseband as me..
As always, thank you!!

Check This thread to see if you can root without mesing with KNOX
It doesn't matter what Samsung software is on the device when you exchange via the JUMP programme from what I am aware, so long as it's original Samsung TouchWiz
There's loads of ROMS for 4.3 and 4.4 - however the 4.3 are not updated so much now if at all - AllianceROM currently still support 4.3 and is a very good ROM - There is plenty now for 4.4 - and I mean plenty, @civato does some great kernels also and his ROM FlexKat is pretty great. - XNOTE is another big ROM for 4.4 as is Omega and SweetROM all of which are just great. You have to try them to get a feel of which you prefer though
Kernel flashing/Custom recovery flashing will indeed trip your KNOX. There is(was?) a method in the General section about how to do it safely via Mobile Odin PRO. but you'd have to read up on that.
As for the T-Mo counter, I cannot comment on that as I do not have an N900T however you can look @ the T-Mo forum for more answers which is HERE
Root De Late Vega will allow you to root without tripping Knox, provided that you do not update the phone.
After rooting you can use mobile Odin to flash 4.3 version MJ7 but you cannot update to KitKatt if you wish to keep both root and Knox 0x0. KitKatt has a new bootloader which is patched against the Vega exploit.
Sammobile.com is the place to find sock firmware. To Vega it you'll need the stock BMI7 firmware for your device to begin.
You must not flash any custom recoveries or kernels if you wish to keep Knox intact either.

Hello
I recently got my S4 i9505. I'm planning to root it
I have Android version 4.3
I used to flash costum roms on my s2 but I'm not really planning to do much flashing on my S4. not soon anyway
So as I connected the phone to Kies to make sure the drivers were downloaded so I can proceed with rooting
Firmware update popped up
I'm not sure what the best option for me now.
Should I root now and then I'd be able to flash a costume KK rom? and are there any stable ones that are better than the stock?
Can I use kies to update my rooted phone?
Maybe I should stick with JB 4.3? Which one is better 4.3 or 4.4.2?
I remember facing some issues when I update my s2 back. So I searched for the KK Update for the s4 and some people weren't so happy with their KK update
I know that doesn't represent the majority but still it could happen to me
So I confused myself
What is your advice to me?
sorry for the long post
Also I have an extra question What is KNOX? and do I need it?

First, the most problems in 4.4.2 are fixed, so if you flash the officical, latest firmware of your country you shouldn't have any problem.
An important thing: if you flash a custom rom, your warranty will be set 0x1, that means, you lost your garanty if you flash a custom rom, that's the so called KNOX. You can use knox like a second system on your phone, with all secure data in it, you can only access with a passwort and all datas are locked without this passwort.
Root your phone after the software update if you want to root it.

That's wrong, just not with towelroot.
thank you for your input
Hi everyone.
I received my Galaxy s4 yesterday the c9515L variant and it came with the 4.4.2 version of android. Using TowelRoot I rooted it and now is working fine , It constantly wants me to upgrade to the newest version (I guess 4.4.4) and I wonder if i'd loose the root and if the Knox would be activated once I try to do the root again.
Also I installed Xposed and some modules, did that trip the knox?
Also, Is there any ROM available that won't trip the knox to 0x01 and having more features thatn stock? I guess to install the Rom I'd need Recovery and thus tripping knox...
Sorry for asking so many questions but as you can see I'm new to the SGS4 comunity.
Thanks.
1. Do you mean GT-i9515L? coz C9515L doesn't exist...
2. The update isn't android 4.4.4 for sure.

First of all, my mistake, what I meant was I9515L.
And, If I currently have the 4.4.2 and it wants to make a system update in "your" opinion what would that be? 4.4.2.1?? No? I though so..... thats why I said 4.4.4.
Any information regarding my questions would be much appreciated.
Thanks.

Tale a look for example in Sammobile.com your updates and you will know something more of your device. It is likely that new models of Samsung using TW will update directly to android 5.0 Lollipop in early 2015 (but your device no maybe). Press "THANKS" button if the info helped you and Merry Xmas

Hi mate
You can root with this:
http://forum.xda-developers.com/showthread.php?t=2292615
The only problem is that the knox bit will be set and the warranty gone......other than that it will work, unfortunately there is no method to root the i9500 without tripping the knox bit .
Hey guys i have a galaxy s4 19500 running android 4.4.2 kitkat ( argentian (aro) firmware )
My phone was recently on 5.0.1 lollipop (indian ) version and i downgraded to 4.4.2 argentian firmware following a thread here on xda
I was wondering if a downgraded to 4.2.2 JELLYBEAN was possible ?
I mean i know it's super messy becuase of knox but if we take all the precautions like backing up efs partition then can the downgrade be done ?
I really think that jellybean is the perfect firmware for s4 and kitkat and lollipop have both made my s4 experience only worse
It would be awesome if i could go back to 4.2.2 jellybean and enjoy my old device
If you downgrade to 4.2.2 you will brick the device. Since new bootloader( version of Android 4.4.2 i think), you are not able to install 4.2.2 without brick.
@sgalchev: Not true at all. It is possible to replace 4.4.2 with 4.2.2 as I have done it in order to resolve issues I had with my S4. What ends up happening after doing the downgrade is that upon every boot and upon every trip into the recovery you will get a notification that the kernel or recovery is not SEAndroid enforcing. Other than that everything works normally.
Now, downgrading from 5.0.1 to 4.2.2 may be a completely different matter, but I suspect it too is possible.
Yea, shure, but you can't do it without ticking the Knox flag[emoji6] Goodbye warranty...

Hey man it feels awesome to know that it is possible to do can you please give detailed explanation of how you did it
I would really like to do it no matter how much hard or risky it is and i have already downgraded from 5.0.1 to 4.4.2 now i just need to downgrade to stock out of the box jellybean software
@sgalchev: Changing the goalposts? You flat out stated the OP would brick his S4 if he attempted to downgrade. When called on it, you switched your argument to tripping the Knox flag. As he mentioned in his latest post, he had downgraded to Android 4.4.2 from Android 5.0.1, so it's likely his Knox flag is already tripped. Even if it wasn't, I can't comfirm whether the Knox flag will get tripped as my Knox flag was tripped when I bought my I9505. Tripping the Knox flag != bricking the S4.
@tdssmarty16: Keep in mind that while everything worked, it took two flashes of the ROM to do it, and I only kept it on 4.2.2 long enough to verify that the hardware and firmware issues I was having were resolved. I then went back to 4.4.2. In downgrading to 4.2.2 I went to sammobile.com and downloaded the 4.2.2 firmware from them. Other than that, I simply treated it as if I was doing an upgrade through Odin. Unlike going from Android 5.0.1 to Android 4.4.2, going from 4.4.2 to 4.2.2 should be a piece of cake.

Hi I would appreciate alot if someone can teach me how to downgrade form 5.0 to 4.4.2 or at least 4.2.2 . I spent the whole day yesterday figuring out how to do it i'm not good with technology and I'm using a macbook. I'm using S4. Thank you.
Which model S4 do you have? Only certain models can be downgraded to 4.2.2.
Downgrade i9505

I downgraded my i9505 from 4.4.2 to 4.2.2 but had no sound so I went back to kitkat.It is possible to downgrade but I don't know is it possible to be fully functional.
I did it long enough to both check my SIM tray at the time, and to unlock the device. I wasn't getting any signal (expected), but I didn't check sound. I do suspect that if the 4.2.2 modem is flashed a second time everything would work. The only indicator that you were ever on anything higher would be the warning the bootloader pops up on every reboot about SELinux.
No sound,no wifi
I forgot first time to say wifi also didn't worked.I don't care for my warranty because flag was already tripped and now my device is older than 2 years so I can try some solution If someone has one.
anyone active here? it's not possible to downgrade to jelly bean anymore as the bootloader is locked to downgrade max at 4.4 as 4.2 will not work at all
if anyone has a ideea on how to do it (some people did it) i would be verry happy if you could share that info
I have not seen a post where someone running a 4.4.2 or 5.01 bootloader had successfully downgraded the bootloader to 4.2.2
