Hey all, I'd like to install this rom, but my phone (S4 international GT-i9505) is KN0X tripped on 4.3. I currently run 4.3 stock. Is it safe to install this rom, and is it possible to downgrade back to 4.3 stock after?

Yup you can flash any custom rom via custom recovery and Yes you can still downgrade your phone into 4.3 stock rom but remember not to flash a Stock 4.4.2 Kitkat firmware because flashing 4.4.2 firmware can no longer downgrade to 4.3 stock rom. Flashing any custom rom/root will trigger your knox and If you wanna know more about knox , check this thread Have a nice day.
Hello, i am currently at 4.2.2 firmware (I9505XXUBMG4) and i have a EFS backup and a nandroid backup. i wish to upgrade my phone to 4.4 but i not sure because maybe if i do not like the 4.4 i will not be able to downgrade to 4.2.
can i go back to 4.2 from 4.4?? i don't care about the warranty or the knox feature

Hi ,
Once you upgrade your bootloader is not possible to go back to 4..2.2 (or 4.3)
You upgrade your bootloader if:
Flash a stock rom 4.3 and higher
you do not upgrade your bootloader if:
root , install custom recovery and flash a custom rom , there are a few good rom based in samsung stock 4.3 and 4.4.2 you can try them see if you like them and if you don't you can always flash stock 4.2.2 and be as you were
Ok, so essensialy i can't downgrade the bootloader to 4.2.
but a official 4.2.2 firmware (without knox) will work on a 4.4 bootloader ??? (again i don't care about knox working or not)

You are asking the same question again. It's not possible.

It has been done to 4.3 in this thread: http://forum.xda-developers.com/showthread.php?t=2744061
they have flashed a 4.3 ROM without bootloader over a 4.4 ROM so the result is a 4.3 rom with a 4.4 bootloader

HI ,
Mate if you flash with Odin or OTA (kies) you will change the bootloader , ok? so once you have a 4..4 bootloader installed there is no way to install back a 4,2,2 stock ( official ) firmware , 4.4.2 official firmware includes 4.4.2 bootloader and flashing an older bootloader than the one you have is not possible (yet)
your options are:
4.2.2 bootloader
stay there do nothing
Upgrade to official 4.4 and not be able to downgrade to 4.2.2 official
root , install CWM and install any custom rom you want ( 4.2.2 , 4.3 or 4.4.2 and 4.4.4 ) and if you do not like any of them go back to official 4.2.2
Once you upgrade to official 4.4.2 there is no way to go back to official 4.2.2 , the only way to go back to 4.2.2 would be with a custom rom

No . I did not say that
Once you are in an official 4.4.2 firmware , the only way to use a 4.2.2 rom would be by flashing an un official 4.2.2 custom rom

Ok mate ,
Good luck .
Hi everyone,
I have a Galaxy S4 that is a Canadian version (SGH-i337m).
It is currently running Android Kitkat 4.4.2 (Latest Update) - Stock Android.
As I do not like it, has so many buys and seems a battery killer, I was wondering am I able to downgrade to JellyBean 4.3?
Things you need to know about my device;
It is currently KNOX void 0x1
I have downloaded an official Android JellyBean 4.3 that is the stock to this phone
Is it possible to downgrade at this point? I do not want to install a cusom rom, I want to install the official JellyBean 4.3 that I have
If it is possible, can someone please tell me how?
Thank you
No its not possible, you'll brick ur phone

Hey all, Back from kryosleep after long time.
Was wondering if downgrading to 4.2.2 [1st Firmware, when shipped] possible from the 5.0.1? Back then the Bootloader, modem, etc were separate and knox was unheard of.
I just want to downgrade to 4.2.2 or 4.3 if possible.
Awaiting answers.....
Regards,
Achyut.
No impossible with stock. Only with custom rom (if you find any still out there).
