You can flash Custom roms like Omega v13.1, i get to use 4.3 rooted without KNOX.
Just flash a custom recovery and install from there. Do read instructions carefully when installing.

Guys, unless you want a knox enabled bootloader on your phone. Stay away from the official 4.3 rom. If you have no idea what Knox is, then you should read the thread about it.

You can also install PAC MAN Rom, CM, Paranoid Android etc. Knox Free

Downgrading my samsung galaxy s4(I9500) to 4.2.2

Hey guys i have a samsung galaxy s4 on android 4.4.2 kitkat and i am not happy at all with the kitkat update since it has ruined battery life and is causing many other problems like lag and overheating
So i want to downgrade to the stock 4.2.2. I have never rooted my samsung galaxy s4 and i am still unrooted.
I know knox will be set to 0x1 after downgrading but i do not care about it as triangle away supports galaxy s4 now .
So here is what i want to know
If i download the proper 4.2.2 firmware from sammobile according to my country(India) and install it via odin then will the process work? and if it is the right procedure does it require root ?
Is there any chance that my phone can get bricked because of knox ?
and how should i take backup of efs in case of a possible imei error ?

I know how to downgrade i9505 but i9500 Im not sure about it I never tested it out
I think you can downgrade successfully, I have a thread about how to downgrade from 4.4.2 to 4.3 but its for i9505 check my profile threads
You can downgrade successfully if you follow my guide, but you will lose wifi of maybe imei
So you can solve 4.3 wifi problem by downloading 4.3 kernel
You can use the same way to downgrade from 4.3 to 4.2.2
And for how to backup your imei you will need a rooted device !!
There some apps that backsup imei
Just look for your phone model "gt-i9500"
And you can backup you system starting from imei by having custom recovery like CWM and do Nandroid
And Knox will be tripped

Hey dude,
I don't really understand how the s4 lags - did u try resetting the device?
the battery life is fine with the latest update.
Overheating is still there in i9500 & also it cools down rapidly - I guess its a HW design. Hope it wont be fixed.
I was annoyed with the overheating issue & now i am used to it. It heats while using 2G or 3G Internet & playing games.
Using regular apps it doesn't heats up & now i am okay with it.
Regarding the downgrade, frimware from sammobile will work fine. You will have to install via odin.
no your phone wont get bricked cos of knox - I suggest you to follow a video tutorial and do the downgrade.
But I recommend you to try a custom rom such as Omega, Hassan etc
In my experience the these roms are very good on battery and performance. Pls do note these roms (Omega, Hassan) are based on samsung stock rom.
If you still want to downgrade, I would suggest you to take it to the service center guys & they will do it for free.
Hope this helps!! :good:

Yeah it mostly gets heated while playing games and using chrome
Though i can still live with the heat because eventually i will get used to it after some time
But the lag is killing me
My phone shows lags while entering and leaving apps and camera and gallery too and it was not lagging before on 4.2.2
Also i have experienced significant battery drag
While using the internet it falls of by 1 percent every two minutes
Is this kind of battery drop normal ?
I am really missing the old firmware so i think i am gonna go to samsung and get it downgraded from there
Thanx for the sugesstion bro

I think will be not easy. You voided ur warranty when u downgraded (KNOX:0x1). No service centers will fix it (in theory) :highfive:

No Performance Lag & Good Battery Life

Hey bro,
In my experience with the S4 on Stock ROM I never experienced a lag.
Please check on the settings - switch off the gimmicky features such as Air View, Air Gesture, S Beam, Air Gesture, Motion, Palm Motion etc etc.
Settings --> Connections Tab --> NFC, S Beam, Nearby devices, Screen Mirroring
Settings --> My Device -->(scroll down) motions & gestures, smart screen, air view
Turn locations off
Check the battery graph - see which app consumes more
I had this issues when these features were on.
The phone will be always hot, battery was draining like 1 % for 1 to 2 mins.
There is no lag with camera and gallery.
Battery drag is bit similar that I lose 1% for every 3 to 4 mins on 2/3G Internet. But on Wifi battery is solid.
In my opinion battery is very solid in S4.
The latest firmware is very stable. The performance has increased from old firmwares.
If you hv rooted the device, and got custom recovery just try a custom rom.

Okay i think it would be good to try the custom rom
So i am gonna try that and see what happens

As I know, if you download an official firmware of samsung from sammobile, you can downgrade/upgrade your firmware without rooting, just flash via odin. Maybe you can uninstall KNOX first before downgrading, open KNOX mode and press menu and click uninstall KNOX. I hope this helps. Good Luck

Upgrading from Custom to Stock

Hello everyone.
I've just installed Sweet ROM V4 MJ7 and I wanna update to Stock 4.4
So its rooted and CWM is installed.
Here's my question...
Should I just put 4.4 stock to Odin and install or should I do sth else?
I know, this question could be so frustrating for someone but it's my first NOTE and i dont wanna mess it.
Also, is it worth to update from 4.3 to 4.4.2 (N9005XXUGNG1)
Im afraid of this knox 2.0
Thanks for help.

Yes..it is the way it should be using odin to install stock firmware. This is gonna be fine bcoz u are going to 4.4.2 unless you are downgrading which is too dangerous.

Just tell me my friend now if it is worth to upgrade to 4.4.2?

For my personal prefence, I like to be up to date all the time. So I would stay with latest update. But some people prefer to stay with 4.3 bcoz of better battery life or other wifi issues. But all bugs have been fixed in these days. So I guess the main reason to stay with 4.3 is just bcoz of battery life. I cant tell exactly how much difference of battery since I just upgraded to 4.4.2 as soon as I got this. So I cant notice 4.3 that much in less than a day. ?? go for it. What is bothering you! You are holding Note 3 and life isnt worth if u don't stay up to date.

Downgrade Possible?

Hello folks,
So i just bought a new Note 4 SM-910C which is running android kitkat 4.4.4 out of the box. Everything is working fine except kitkat feels outdated and lags sometimes its not as fluid as lollipop on my Galaxy S5. I was thinking of flashing the stock lollipop rom available for my country from Sammobile. But as i was searching through forums....i read somewhere that its not possible to downgrade once you have upgraded to 5.1.1 or 5.0.1 . Kindly confirm the following
1) is it possible to flash stock 4.4.4 after flashing stock 5.0.1?
2) If i upgrade even further to 5.1.1 from 5.0.1 will i still be able to downgrade from 5.1.1 to 4.4.4?
3) Will any of these trip my knox (its imp as my phone is still under warranty)
Hardware question
the power button on my note 4 feels bit loose....its like i can press it from one side and the other side would come up a bit.....but it presses and clicks perfect nomatter where i press it ...upper end ....middle or lower end...is this normal for it to be little loose or should it be rock solid?
:good::good::good:
HELP WILL BE APPRECIATED BEST REGARDS

So. U CANT downgrade stock samsung rom. Because of the bootloader from samsung. And if u do. It will just brick ur device. And IF u rooted and have custom recovery. U can just like download kitkat rom that flashable from recovery. Then just do flash. And DONT install like lollipop rom if u still on KitKat bootloader. It may cause prob so if u have like L bootloader. U can go to kitkat using cusrom. (NOT ODIN) so yeah good luck

Im unable to understand what you Just said can you please simplify it.....andwhat about the hardware issue that i just mentioned i went to Market to check a few other phones only one of the six i checked had the same wobbly power button. Is this normal ?

The wobbly button is normal if u use it on long time. But. The downgrade is the hardware prob. Samsung decide that so we cant downgrade. If we do. We brick our device / destroy it. But if u use lollipop then root and install like kitkat custom rom via custom recovery. It will work fine. Because it didnt flash the older bootloader
