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
Downgrade or Install Custom ROM

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

Which file did you try to flash it with? I used one from a guide but I'm not allowed to link to anything because I'm a new user
Not sure if that's the wrong one or what's up...

I've followed the guide in this forum downloaded the file from chainfire site for my exact model but it didn't work only ended up in samsung logo. I am even unable to shutoff my device, be aware that CF Auto root method is not working on latest patches. If u r stuck in samsung logo flash stock firmware via odin then u r good to go....
