Hi, i have an s4 and i am still on the 4.3 bootloader. I never officially flashed 4.4.2 tw. I can flash all 4.4.2 roms just fine everything works. So my question is..should i update it? Should i not? What are the downsides and upsides. Also i believe my knox is already tripped and my warranty is gone because i hastily updated to 4.3 from 4.2.2 so yeah if knox is out of the question is there any harm in updating my whole phone to 4.4.2 bootloader/modem etc

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.
Reading the forums, and i am more confused than when i started.
Anyhows i have a Rogers i337m at 4.2.2 rooted. Want to upgrade to 4.4.2 and avoid the Knox Trip. From what i understand 4.2.2 doesn't have knox. It came from 4.3 and above.
So whats the best approach to go about the upgrade that would allow me to come back to 4.2.2 so i can put it back to stock if required.

Install a custom recovery and install a 4.4.2 KK ROM - don't do the official update. The official update will update your bootloader allowing you to only SafeStrap and install TouchWiz ROMs.

Go with Mapple leaf from iB4STid. works good on I337M.
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.
Hi,
I have experience with the Canadian S4 I337M, currently running custom Validus ROM 5.1.1, originally was on TouchWiz 4.4.2;
I have altough a question that seems quite.. debated, did looked around I can't find a definitive answer and know who I should trust. I wonder if options changed in 2015 rather than 2013 when KNOX was still new.
Out of simple curiosity (I will not attempt it, risky, probably useless and I'm running 5.1.1 anyway): I keep reading that it's impossible to downgrade the S4 to 4.2.2, due to the KNOX bootloader on 4.3 / 4.4, I understand that you cannot downgrade below 4.3 which is the "new" KNOX bootloader.
1. I'm simply curious: On the I337M, what happens if you grab the stock 4.2.2 firmware and flash it with Odin anyway, considering I'm on 4.4 ? My guess, if I'm correct, Odin detect the bootloader version right away and says "FAIL". Correct?
2. I used to think it was possible to downgrade from 4.4 to 4.3, since 4.3 has the KNOX bootloader as well. Is this possible anyway, or will Odin fail (Not going to try it, not worth it)? Considering what I've read just today, 4.4 is also a new bootloader. In any case, since that 4.4 bootloader cannot be downgraded (I guess?), there is no way to downgrade from 4.4 to stock 4.3 either? Odin will show "FAIL" ?
3. Is there any other way to downgrade it anyway? I understand that KNOX 0x1 remain irreversible yet, and to my knowledge, it's impossible to dowgrade to 4.2.2 (Or even 4.3?), but I've been reading that it was possible to downgrade if the bootloader is excluded from the TAR archive, make sense to me, but is that true, was that patched? Should I recompile an ODIN package excluding the bootloader, is that how it's done (Too dangerous, not trying it)? Or maybe by using Mobile Odin / FlashFire, downgrading from 4.4 to 4.3 / 4.2 can be acheived, if the bootloader is left untouched? What happens if we try it anyways? Odin fail, or device does boot but doesn't get past Samsung boot logo?
I'm just wondering, and quite confused by the different opinions that were shared. Remember this is for the Canadian I337M variant.
Thanks for confirming, appreciate!
So I got my father's old Note 3 after I lost a Z5 in Disneyland, I updated from JB to KK through OTA and installed SuperSU with Towelroot (Knox is still 0x0). I want to clear up some confusions before I go ahead and trip Knox:
AFAIK 4.4+ boot.imgs are not compatible with 4.3 aboot (and vice versa) and you can't downgrade the bootloader once it's updated (you can't odin a older firmware as a result). Will MM roms work with my current BL (rev counter 2)? I wasn't happy with the performance of stock 5.0 the last time I used a N3 and I don't want to risk losing the ability to revert to 4.4.2 if something went wrong with 6.0.
I'm probably sounding stupid but I never tinkered with a Samsung before.
MM is worser than LP so stay with KK.
I like my AryaMod 6.0.1 ROM, but no clue about BL. I always use newest. Why is tripping KNOX a problem? Warranty is no more anyways.
