[Q] Cannot downgrade from 4.3 to 4.2.2 - Galaxy S4 i9500

After upgraded my S4 i9500 from 4.2.2 to 4.3 XUEMJ5 via Kies, I'm having a lot of troubles regarding battery drain and overheating.
I came to the Samsung Services Center yesterday and asked them to downgrade my device back to 4.2.2, but their answer is "Sorry, we cannot do it. Once upgraded to 4.3, there is no way to reverse to 4.2" ?!?!!?!?!
Is it true? Has anybody tried to downgrade your S4 from 4.3 to 4.2
Thanks for your advice!

I had the same issue. There seems to be a problem downgrading to certain 4.2.2 roms. I eventualy managed to downgrade using the South African version (I9500XXUBMH1) . After you've flashed this,you can re-flash whichever ROM you prefer.
Give it a go and let me know.
Cheers

you are you kidding

Are you really serious? So you can downgrade from 4.3 to 4.2.2 using that firmware? What does your knox say in download mode?

Unfortunately it states:
Current Binary: Custom
System Status: Custom
Warrant Bit: 1
But it doesn't really bother me for now, until I have to send it back for repairs I guess
I'm sure the Chainfire guys will eventually be able to reset this counter as the TriangleAway is currently not supporting the GS4 I9500.
Cheers

So is there a specific way you have to flash it or do i just use odin?
Do i flash the roms back to back or what?

You can flash stock rom 4.2.2 through odin to downgrade. You can find the rom in the forum of I9500 or on sammobile.com. But you may face problems with IMEI. Happened to me.

[Q] rom Question

Hi
Im new to Android and got some questions. I ´v been reading but at this point i rather ask.
I got an I9505 Int unbranded model on 4.2.2 (UBMGA) knox free. I would like to try out some roms but be able to revert back to stock for official updates in the future.
I would like to tryout GE of the latest 4.4.2 without knox or locked bootloader is that possible?
Also if its possible to install an official 4.3 TW version without the bloatware?
Just need a push in the right direction.
Thanks

You can start rooting your phone and then flash a Custom recovery such as Philz/TWRP/CWM and flash any 4.3 Rom's (Bloatware) you like and make sure its a knoxfree rom. and about 4.4 kitkat it wont work for us Oldbootloader (NOWIFI) since Samsung did not release any kernel source yet . so be patience . Until they relase the Official. Have a nice day.
And If you wanna go back just flash a 4.2.2 Prerooted BMGA stock > Reset binary > Flash a normal Stock 4.2.2

No worries mate , feel free to ask anything here if you got any problem , and im sure alot of xda member's will try to solve that problem "Btw if your flashing a custom rom via recovery make sure to wipe or follow their instruction in order to prevent any issue .

No. Unless you flash a Knox-free custom ROM, but you can't do it with the official one

KNOX

You cannot downgrade from 4.4.2 to 4.3 and if you have a 4.3
nandroid backup you cannot restore it either.
You will only be able to upgrade or flash 4.4.2 roms and newer
versions of android roms/firmwares.
Oh, one more thing there is no such thing as "denox" LOL
Good luck!

Yeah you can flash Stock via ODIN or you can install CWM/TWRP and use a custom recovery. -- Make sure REACTIVATION LOCK is OFF before you do anything or it won't work.

note n9005 JB ROM 4.3

You may find by search in general section .
Or from the usual stock sources. Samsung-updates or sammobile .Or via google search.
But your Kies backup should have it from when you backed up your original rom.
Sent from my SM-N930F using XDA-Developers Legacy app

You are in a Lollipop bootloader, you cannot go back to JB (stock) anymore
You need to root and flash a custom ROM based on JB

Seriously, at this day and age you're better off just sticking with Lollipop.
I know I'm spoon feeding, but I figured what the heck. Here:
Jellybean based ROM
Kit Kat based ROM
I have not tested these ROMs nor am I responsible for what you do with your phone.
Please please PLEASE, DO YOUR OWN RESEARCH
Just whip out the old google, it doesn't take that long.
