First of all Hi everyone!
I bought an S4 for my girlfriend and have a question regarding this Knox bullsh*t. When I bought it out was running 4.2.2 i9505xxubmga firmware. I rooted and installed aosp rom on it. But she doesn't like aosp apparently..
So i wanted to know if it is possible to flash 4.4.2 Samsung rom without upgrading the bootloader to Knox enabled one?

Hey,
sorry, this is not possible with stock Samsung rom. When you upgrade to 4.4.2 knox bootloader will be activated. But it is possible to go back to 4.2.2 mga, this firmware uses the old knoxfree bootloader.
Edit: i think you can install a Samsung based custom rom like imperium rom, this is also knox free and compatible to the old bootloader but I'm quite not sure whether this will enable knox. I think it won't...

You can flash any custom rom you want. 4.4.2, 4.2.2, 4.3 etc. It doesn't matter.
You need the correct modem though if you have the old bootloader and anything above 4.3+ rom. You have to do some searching on the correct modem I can't remember which one it was.

p.s i couldnt find any other post which could help me so if there is any,can you guys please post the link also
If you are still on 4.2.2, then I would recommend to not upgrade to a 4.3 stock rom. Doing so will flash the new bootloader which will setup Knox on your phone. When you have the new bootloader and you flash a custom rom, Knox wil be set to 0x1. You can read more about Knox in the Knox thread.
If you planning on flashing custom roms in the future, then stay away from official firmwares.

You can flash any custom rom based on 4.3 that you want. Because custom roms don't flash the bootloader. There seem te be some problems with sound and wifi (but i'm not sure) when you flash a custom 4.3 rom on an old bootloader. But you can always revert to a custom 4.2.2 rom. So you can just try it
Just don't flash originial firmwares. Custom roms are safe.

Thanks for the info bro..i just wanted to know whether I would be missinganything significant If idont updateto 4.3.3 or any 4.3.3 roms, cause of the problems you mentioned
sorry to highjack the thread as its a noob question but wanted to make sure.
I am on MH8 knox 0x0.
If i flash the 4.3 MJ5 stock firmware via know will it trigger knox? i have no intention of rooting just to upgrade to official 4.3?
I currently have 4.2.2 with the old bootloader on i9505. I would like to keep it Knox free, but would also like
to try a newer rom. Is there a rom that is as close as possible to stock Samsung 4.3 (obviously
without Knox or new bootloader)?

Which modem would suit the PDA: XXUEML6 version? The same one that came with XXUEML6 in stock? I have heard conflicting reports about different modem versions playing not so nice and its better to match them with what came with stock rom?
I assume also that XXUEML6 WiFi_FIX will need to be flashed via Odin after flashing a modem?
clarification
So do you mean without knox and without bootloader or do you mean or do you mean without knox but with a bootlaoder as it is the older bootloader that i am trying to find for i9505. i understand some forums say you cannot roll back the firmware from 4.4.2 to 4.2. I however am having the screen rotation problem with the new 4.4.2 so i'm trying to find a way and one way might be to install a custom rom with old bootloader via CWM install zip function to replace the new 4.4.2 bootloader. This will then allow me to roll back the firmware to an older version and kill my screen rotation problems.

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.
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 Everyone!!
Thank you for looking at this thread.
In a nutshell, I got my i9505 galaxy s4 since June 2013, rooted it straight away when i got it, its got twrp recovery, and im on omega v9 4.2.2. Havent touched it since to date
It does not have knox.
Is there a way I can simply upgrade to something like cm 12.1 with 5.1.1 with everything working, by simply flashing latest cm with gapps using twrp, or will I have to upgrade bootloader, radio, get knox, or even just start over, flash stock samsung lollipop firmware with knox using odin, in order to do so?
I already a while back tried updating twrp to latest, and tried flashing cm with lollipop 5.0 when it first first came out, but only 2g was working, and signal would cut if i lock my phone. Im guessing this is due to bootloader/radio incompatibility, or maybe because it was early builds? Apparently i cant flash lollipop bootloader and radio over old 4.2.2 stuff without consequently installing knox? Is knox that bad? I heard its better to not have knox but if its the only thing stopping from lollipop then so be it.
Any help and advice much appreciated.
Hope to hear soon,
DJ
You can try upgrading just the modem to be able to flash an Android 5.x ROM, but it likely will not work and thus you will have to flash an updated bootloader as well. The good news is that since your S4 is out of warranty, whether you trip the Knox flag or not will not matter.
You should be able to flash the updated bootloader and radio without having to install an entire ROM, though you might want to download the latest ROM for your S4 anyway. There is a thread in I9505 General that has a list of bootloaders and modems that can be downloaded and flashed through Odin. From there, you should have no problem flashing the custom ROM of your choice through recovery.
