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.

I was in stock I9500UBUBMG1, then I used auto-root and after that I flashed cwm recovery via odin. Everything worked fine in despite of Custom Binary and custom system status in dowload mode. So tried miui rom, but after 2 months I decided to come back to stock I9500UBUBMG1.
curiously, all status are Official again.
Is that normal? since I just use stock 4.2.2 (old bootloader) or custom roms I can always return to official?
If I update via OTA will still official and show knox 0x0? (not that I would update).
If I install a 4.3 or 4.4 based rom I can return to MG1 with offical? or just if isn't TW based?
Thanks
I too have a question relevant to Knox behaviour: I am on Stock 4.2.2 MG1 firmware. I would like to Root and use Custom firmware. Any possible way not to trip Knox Counter? Anyway to save or backup my current modem / firmware, so that I can flash back to it if Knox is tripped?

if you update your phone to a rom with knox bootloader, then you can't root and install custom recovery without tripping knox flag.. otherwise, on 4.2.2 you can root and return to stock rom(only 4.2.2) to get fully official status.. consider flashing latest roms modified to support old bootloaders.. so you can keep away all knox things... press thanks if it helps..

As we are in the old bootloader, we don't need to complain about knox, since we can flash stock MG1 back. You just need to pay attention because some custom firmware are imcompatible with old bootlader (or modem, idk) and if i'm not wrong, some custom roms can update your bootloader. There are some methods that will not turn your status to custom, but I think that auto-root and flash custom recovery is the best way to install a custom rom.
Thanks so much for that info!
I've Rooted using Ryebread76's method:
If you plan to flash custom firmware, as in a ROM, your going to trip KNOX. If you just want root, I used saferoot. It's for the VZW version, but it works just fine for the i337M.
Any suggestions on Custom Recovery / Firmware that will not change 4.2.2 MG1 bootloader?

It will not trip knox, since it is not activated in MG1.

If I already rooted and on custom roms since 4.1 or 4.2 (Before The Knox 4.3)
Do I have to worry about downgrading custom roms from 4.3 to something earlier?
Like triggering something or bricking the device...?

1. Android 4.3 have new bootloader. You cant downgrade from android 4.3 (if u install ur firmware by OTA, ODIN or KIES) to something earlier.
2. The unique u can do for no update ur bootloader (before the Knox) is install one custom ROM by Custom Recovery . The result will be android 4.3 with old bootloader (no void ur warranty: KNOX 0x0)
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
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, recently I received the Marshmallow Update for the Note 4, and I have been procrastinating to update it to 6.0, and I know I am being skeptical, but if there was a chance my battery life would get worst, is it safe to downgrade with firmwares from sam-mobile? Would it trip the KNOX counter? How do I get the original firmware off my phone without rooting it? I know it's a choice to update or not, but the 6.0 Notification is annoying and tempting.
BUMP
Sometimes you have e to jump first.
First things first:
1) Like kitkat, marshmallow has the best battery backup. You won't have any problems with the battery if you do a clean install through odin. (What I mean by clean install: first wipe data/factory reset through recovery before flashing through odin).
2) Upgrading-downgrading doesn't trip the knox counter if you flash only samsung official firmwares. Rooting or flashing some other software does trip the knox.
3) The ability to downgrade from marshmallow depends on which phone your having. For example mine is the SM-N910G snapdragon variant. Here in India when they initially released marshmallow, it didn't come with a locked bootloader. Hence we could downgrade easily. But the new marshmallow updates that came later had locked bootloaders.
yes, i've done that.. no problem at all
