I'm a little confused about which ROMs I can use on my N3. I have a N900W8 Canadian Rogers hltecan phone with bootloader and CSC version MJ4. I am on 4.3 stock right now and I intend to keep knox at 0x0. I have rooted it with Kingo so knox is ok. On my old S3, I just used ROMs from AT&T section of S3. But it seems N3 is quite different.
From my understanding, to install custom ROM without tripping knox, I can go the Mobile Odin Pro route and make sure the ROM that I install has no custom kernels (and also that ROM does not require custom Kernels). The other way to go about it is to use Safestrap, but I don't think there's support for Rogers yet? Also, I cannot install custom recovery (safestrap exception)
Some other questions I need to ask is if I want kitkat 4.4 on ROM's, do I have to find one with the same bootloader version? How would I know if a certain ROM is compatible with my device or can I look in the AT&T Note 3 sections like I did with my S3?
Hope you guys can point me in the right direction! Thanks

coming from the g2x which was incredibly straight forward to deal with not having a locked bootloader or any other nonsense to deal with i have a few questions regarding a rogers s4 i337m
1. KNOX, as far as i have read this is a feature to detect tampering with the device and set a flag in place when tampered with. Specifically what sets off KNOX? as to that i have not really discovered a more direct answer. The repercussions to setting off KNOX is unable to use KNOX secured software aka roms/kernels? Is there any current updates by any of the providers that actually utilize this? or is it just more a enterprise feature being tested out in the s4 for additional security measures.
2. editions of roms, i honestly found a thread earlier for this but am failing to find it again i cant remember which s4 sub forum had it regarding the differences between google/asop/tw roms.
3. What are the mainstream Roms/kernels used, i noticed faux123 combined his rom/kernel of which i was not a fan of. for the G2x you had faux/morfic for kernels and just running stock cm7 was quite flawless for a combination.
4. I need a link to the latest CWM or has that been replaced for another recovery software? I know you can download it through rommanager but i thought that was like a fake flash more so then acutually pushing it to the phone via some other method. Is that done through rommanager as another step to avoid tripping knox? touch CWM is not essential and i recall the g2x touch CWM had issues so i don't really care if a legacy version can be used. stability > features for core components.
5. Having the unlocked bootloader has any other gains other then just not having to downgrade to a unlocked bootloader for flashing custom kernels/roms? flashing the roms even with the unlocked bootloader will still trigger knox correct?
I am quite aware of the safestrap feature and may try that if knox is required in any way. for warranty purposes i dont really care, if the phone runs for a month then it will probably last me 2-3 years. hell even the g2x survived 3 years now only with the power button becoming a tad problematic to turn on the phone. its more is there any software that may require it that as of now rom wise or app wise.
oh finally whats the difference between odin v3/v4? is there any real reason to use the newer. seems 3.09 is common revision to be used.
Seems like you may need to do a little more reading...but heres a little info for you
First let me ask you a question, what firmware is your s4 on, and is it an i337 (att branded)
As far as knox goes, I don't know much kore about it than you do...havent really looked into it, If you root your phone amd go in the superuser app it will ask you if you want to remove knox
Aosp vs touckwiz roms:
AOSP based roms can vary from pure AOSP, which is exactly what google intended android to be, no gimicks no extra features. But they can also be much more customizable such as cyanogenmod or aokp. Again these roms are built from the android source code, so it looks the way android was meant to be, the non pure ones having mamy added features
Touchwiz roms are simply based off stock realeases, they are often rooted and debloated, with a few tweaks thrown in and maybe a few mods...they typically loom and feel like a cleaner, smoother, and more polished stock rom, and with a lot less bloat
Recoveries: there are several recoveries available, you still got the basic CWM, than you got Touch CWM, Oudahs auto-loki recovery, phils cwm *I think thats the name lol* and than TWRP (may be missing some)***IMPORTANT: I asked earlier what firmware you were on, and this is way, if you have the mf3 firmware or mk2 firmware you CAN NOT flash any of the above recoveries due to our locked bootloader***
Safestrap: this is the recovery alternative which essentially is a recovery, however it is currently unable to flash kernels...which means you can only flash touchwiz roms, that are compatible with the stock kernel you currently have...so if your on mf3 with safestrap only 4.2.2 roms, if your on mk2 only 4.3 roms. Keep in kind safestrap is still in beta for mk2 so not every rom is working.
If you have an att phone with a locked bootloader there is currently and never has been any way to unlock the bootloader, so you are stuck with a locked bootloader. What this means is you can not downgrade to an earlier firmware, and if your mf3 or later you can not get a recovery and flash cyanogenmod aokp aosp or amy other aosp based roms

so if i were to upgrade to 4.3 ota it would flash MK3 giving me a locked bootloader? i was under the impression that the i337m canadian models all have unlocked bootloaders. only the i337 US models had locked loaders. i listed the model earlier and everything is stock out of the box
baseband/build is MG1 on 4.2.2
actually ill just check that latest firmware thread, the candian models are equiv to the m919 tmobile models basically. we also have the m919v for wind/mobilicity.
100% my bad I missed that you had the i337m
So with that said, you dont have a locked bootloader, and theres nothing you can do that will lock it
You can flash any of the recoveries, cwm twrp or whatever. They are all stable and seem to be working fjne...so its just whatever you perfer
Personally I like twrp, and that can be installed using goomanager if youre rooted, rommamager should also work if your rooted for cwm recovery

Haven't played with custom rom for awhile as well as rooting/recovery.
Now that Samsung implemented Knox, I'm reading this is changing how to implement roms and upgrading/downgrading stock roms.
I am currently on MDJ from MG1 and did not want to go to 4.3 because of the full blown Knox implementation.
So my questions are:
1. Can I still downgrade from 4.3 to 4.2.2 (MDJ)? I read some in one thread you can but others you can't. Have to make sure which thread I read for I337 vs I337M which seem quite different. Reason is that I can still easily repair/modify stuff on MDJ firmware.
2. I am also considering installing Google Edition 4.4.2 ROM as I believe it does not have Knox. Can I easily revert back to 4.2.2 MDJ from a custom rom?
I've been reading for awhile and I can't seem to figure this out. Must be old age. TIA.

The safest thing to do is stay on a version without the knox bootloader. I know for sure I337 can't downgrade, and i think the bootloader isn't downgradeable but the system is or something for the I337M. I'm not sure, but either way the safest bet is to stay without the 4.3 bootloader. That way you can root and use recovery and flash without worrying about knox and you'll easily be able to revert from any custom ROM back to stock as long as you either keep a nandroid backup or the ODIN files for the firmware.

Yeah, I think I'll do that. I also understand the issue with Knox is tripping the counter voiding the warranty but I don't care about my warranty. Going to try Goldeneye when I get the chance or look at some 4.4 roms.
I don't know why Samsung or any other manufacturer just let corporate users enforce Knox or whatever and let the rest of the users alone.
its completely fine flashing custom roms with the 4.3 bootloader for us canadians. the only downside is, you will trip a knox flash counter, it cannot yet be reset. you only see this flash counter in download mode. AND if you have a non-official kernel, or recovery, you get a little yellow message in upper left corner during the first bootscreen.
BUT. if you do not upgrade to 4.3 modem, you will experience data drops (loss of signal randomly) with any custom 4.3 or 4.4 rom.
so you dont have to upgrade to 4.3 bootloaders, but you will need to get the modem, its around, if you are already on 4.3... just flash the phone as normal, you cant go back, but its not stopping you from going forward.
I have the bell smartphone protection plan, if i break the phone, they replace it, and dont care about custom software or booloader flash counters ect. So i dont care either.
For the modem, find a copy of MK6 modem assuming your in Canada, flash it through odin from your pc. If you get a fail, chances are you have a bad download (happened to me) download from a different source then. Before you flash any rom... root.... install custom recovery.... nand backup your current "stock but rooted rom" If you flash a 4.4 rom (not sure if this applies to 4.3) do a full wipe... System/cache/dalvic.... then factory reset... then flash.... I flashed 4.4 the first 2 times without wiping system and though the phone worked fine, data was inconsistant at times.....

I have a Bell S4 with Google Play Edition 4.4.2 running perfectly so far. I had an MDJ modem, and tried flashing many custom ROMs on it. All 4.3 ROMs worked fine, and only AOSP 4.4 ROMs also worked fine. The only problem was the GPE 4.4 ROMs that gave me constant signal drops. So I tried to upgrade my modem to MK6 to fix the issue. Even when I upgraded to Samsung's stock 4.3 through Odin, it still didn't upgrade my modem. I had to manually flash the modem in Odin to get it to upgrade successfully. Then I just flashed a GPE ROM and everything went well.
1. I'm still on 4.3, My baseband is N900TUVUBM17, I would like to root WITHOUT tripping Knox.. Is this at all possible at this juncture? If so, what method should work? (I can follow directions, I just need confirmation)
2. I need 4.3 or 4.4 stock for when I eventually turn this phone back in for the JUMP program to get the Note 4, is there a link somewhere?
3. Are most ROMs for the Note 3, 4.3? And if there are 4.4 ROMs, can I flash those if I root my phone on 4.3? I'm interested in SlimKat mostly with Lean Kernel.
4. I heard that flashing a kernel or ROM will trip Knox, so how does one go about doing any of this without tripping it?
5. I thought t-mobile had a flash counter when you turn your phone in (different from Knox), is that true? And can it be reset? If so how?
I'm not new to rooting, and I have read these forms before making this topic. I just need mostly a confirmation on what has worked for people with the same baseband as me..
As always, thank you!!

Check This thread to see if you can root without mesing with KNOX
It doesn't matter what Samsung software is on the device when you exchange via the JUMP programme from what I am aware, so long as it's original Samsung TouchWiz
There's loads of ROMS for 4.3 and 4.4 - however the 4.3 are not updated so much now if at all - AllianceROM currently still support 4.3 and is a very good ROM - There is plenty now for 4.4 - and I mean plenty, @civato does some great kernels also and his ROM FlexKat is pretty great. - XNOTE is another big ROM for 4.4 as is Omega and SweetROM all of which are just great. You have to try them to get a feel of which you prefer though
Kernel flashing/Custom recovery flashing will indeed trip your KNOX. There is(was?) a method in the General section about how to do it safely via Mobile Odin PRO. but you'd have to read up on that.
As for the T-Mo counter, I cannot comment on that as I do not have an N900T however you can look @ the T-Mo forum for more answers which is HERE
Root De Late Vega will allow you to root without tripping Knox, provided that you do not update the phone.
After rooting you can use mobile Odin to flash 4.3 version MJ7 but you cannot update to KitKatt if you wish to keep both root and Knox 0x0. KitKatt has a new bootloader which is patched against the Vega exploit.
Sammobile.com is the place to find sock firmware. To Vega it you'll need the stock BMI7 firmware for your device to begin.
You must not flash any custom recoveries or kernels if you wish to keep Knox intact either.

I'm going looking into flashing a custom ROM on my sister's i337m (on Rogers) . Currently it is on Lollipop OTA update, and she says that ever since the update it has been super slow and laggy. I told her i can flash a custom ROM and it should be much better performance (in my experience good custom roms can provide much better performance than stock firmware in most cases).
I'm not familiar with the S4 specifically but have been using custom ROMs myself on various other phones so i generally familiar with the procedures involved. Just want to ask for advice on a couple points.
1) From what i've read so far i am trying to decide between Goldeneye and Kangapop. both seem to be pretty solid options. I noticed in the install instructions for both it mention that the i337m useres need to have 4.4.2 baseband and bootloader. Is there any specific one that works better than others i see a few different stock versions of 4.4.2 for i337m Rogers on sammobile (MG1, NC1, NE1, NI2) I am currently downloading the most recent NI2. Just not sure if specific versions have any bugs, flaws or advantages/disadvantages to worry about..
2) I figured while i'm going to have to downgrade the firmware to install the custom ROM i might as well try the Root/Unlock procedure from this thread . Is this still working? I think i would need to flash the stock NI2 firmware then follow the procedure in that thread to root and unlock the phone then from there i could install Goldeneye or Kangapop? Has anyone done this or can confirm if it should work this way.
Thanks
Okay so I'm fairly new to the forums but I'm somewhat knowledgeable when it comes to rooting and flashing custom Roms.. At least one the Galaxy S3. So I now have a note 3 and I'd like to root and install a custom recovery and then from there a custom Rom after a little more research.. Because.. Eff touch Wiz. Now I got the note from a friend and it's been fully updated knox hasn't been enabled but has been fully updated and I believe the same thing for the security policies. Now this is where my question comes in I found a method on google (galaxynote3root.com) to root and install the recovery I just wanna know if anyone can confirm this method is safe with the new updates and what not? I'd rather not brick the phone obviously lol anyways the phone model is sm-n9008w unlocked but was a Rogers phone.. Android 5.0 stock firmware and recovery knox 2.3 any help would be appreciated
Which note 3 do you have? Are you sure it's not the sm-n900w8? Depending on the ROM you install, you may need to update to the latest bootloader and modem.
Edit: read your post again. Since stock LP is on the phone, Knox has been installed and the phone would be running the doc4 or doh1 firmware.
The simplest way to root would be to install TWRP and flash supersu from TWRP. You're going to trip the knox counter from 0x0 to 0x1. Also, make sure reactivation lock has not been enabled.
