I am buying a Sprint Samsung Galaxy S4 on Monday. I know it will come with a KNOX-enabled bootloader. My question is, I know flashing a custom ROM onto the device will void the KNOX warranty. But will I be able to switch from Touchwiz stock rooted to… lets say, CM11? If so, would downgrading CM11 to CM10 require an older bootloader (pre-KNOX)? Will custom recoveries such as PhilZ work with the latest bootloader?
Sprint bootloaders are not locked like ATT and Verizon. And Knox doesn't affect the installation of any custom Roms.

hi guys have an s4 in the uk im bored of stock touchwiz an want to install a custom rom. can i do this even tho its locked to 3? or do i have to unlock 1st? or does it not matter cheers guys?
Yes you can, you can change officially via Odin or install custom recovery and flash whatever rom you desire. I got my S4 back last year on o2 then flashed the BTU (unbranded UK version straight away) and now run the Google Edition rom. However I am on the bootloader and can flash whatever I wish without tripping KNOX but only via CWM.
What current firmware are you on?
im on three locked. firmware is the new 4.3 software.
so do i just root an flash cwm and im ok or?
Be aware as you have a KNOX bootloader installing recovery will trip this and you can't reverse it.

so what does this mean?
KNOX when tripped can cause issues with warranty. Now as we live in the UK we have warranty covered for 2 years by the EU. But it's like a warranty flag they could use that against you and not fix any issues, it will also disable KNOX which is a security feature but more for commercial rather than personal and it you will not be able to downgrade your firmware.

hmm so basically if i do this put a custom rom on then decide against it and want to go back to my stock rom or any other rom i wont be able to?
You'll be able to go back to whatever stock rom you were originally on or higher. I suggest looking in the android development section for the pre rooted roms, I think there are ways to flash a custom rooted rom without recovery without tripping the knox flag.

ahh so its better if i just flash a pre rooted rom then?
so u think its better if i dont flash any recoverys but then how do i flash the rom over odin or?
Currently I'm running Beans ROM. Any chance we'll get CM11 for the Note 3 VZW non developer edition?
I don't care about tripping Knox, so if there's a way to do it that involves tripping Knox I don't care I'll do it.
i dont think so..without bootloader unlocked.
It's all about the kernel. We can't flash stock aosp kernels so we are stuck with touch wiz roms. Unless we get an unlocked boot loader.

I have a Sprint Galaxy S4. I old one broke and i got a another using my warranty. There was no way they could repair it. it had a rock go through the phone. My old one had the old bootloader and i rooted it, installed CWM bootloader and had custom roms on it. I liked it that way. My new one had the newer Kit Kat OS on it. I was aware of the KNOX counter on the newer version of android. I know i can root it with out tripping the KNOX counter but can you install custom roms on my phone. What if i don't care about tripping the KNOX counter can i still install CWM or Philz recovery? If so, will KNOX let me install custom roms. Basically i want to do what i used to do on my old phone; freely try different recoveries/bootloaders and custom roms, with out KNOX interfering. At the very minimum have root access and install any of the newer custom roms that are out there( particularly the Negalite rom.)
Yes you can. Search next time please. This has been answered before.

can you provide a link.
I have been searching the forum for hours now, but could not find a definite answer. Please help.
First question: Is it possible to install Samsung I9505 MIUI ROM on I337 ?
Second question: If possible, can someone direct me to a tutorial?
I am asking this about Samsung Galaxy S4 i337 ( USA AT&T version) on 4.4.2
I would bet it is NOT possible for your i337. You say your on 4.4.2, so the only recovery available for your device is Safestrap. Since your bootloader is locked you CANNOT flash custom kernels. To run AOSP/CM/ and most likely MIUI required a different kernel than stock kernel. Safestrap on your device can ONLY run Touchwiz based Roms due to needing a stock kernel.
If you had the Original firmware like MDB or MDL and used Loki bootloader bypass you can run AOSP/CM based Roms and more than likely MIUI as well. With the Loki bypass those on MDB or MDL CAN FLASH custom kernels.

Thank you for the response. Then my new question: is there a version of MIUI that uses stock kernel? I remember reading that some people installed MIUI on bootloader locked galaxy s4 with Safetrap.
I haven't seen a MIUI thread at all. Sorry I could not be of any help with that. How old is the thread you saw? Point it out and I can take a look. Phones with MDB or MDL may have been able to since they use regular TWRP/CWM for recovery, but never seen one for Safestrap.

I am still on an older android, and rooted with recovery. How would one go about flashing the i9505 on here (i337)

I just rooted my OC3 ATT galaxy s4. How the hell do I get custom roms on this thing? Is there a way to downgrade to KK and use those? I'm not new to samsung devices but I am new to the devices with KNOX.

You can downgrade to kk and use safestrap for custom roms. Refer to this forum for instructions http://forum.xda-developers.com/showthread.php?t=2926642
