I337M Downgrade and Custom ROM Questions - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

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.

[Q] Flash a 4,3 TW Rom with STOCK Recovey and Pre-KNOX bootloader?

I THOUGHT what I wanted was simple enough but apparently with Samsung nothing is ever simple.
I have the i9505 S4 and am currently on the Pre-Rooted I9505XXUBMGA rom. That means 4.2.2, Stock Recovery and PRE-KNOX bootloader.
My custom flash counter is also 0 as I've only ever flashed the pre-rooted stock kind of roms. No triangle has ever appeared on my screen.
What I want to do is install a 4.3 TW rom WITHOUT flashing a custom recovery (so probably through Odin) and WITHOUT having to flash the KNOX-enabled bootloader.
The reasons should be obvious enough, I want this phone kept as close to stock as possible with what I do being completely reversible without having to rely on Triangle Away as with every new firmware Samsung appears to be even more hell-bent on breaking it.
Obviously I'd want said rom to actually function correctly as I've read things like sound and/or wifi breaking or mobile data dropping with/without the phone being on sleep etc...
So, any takers?

Hi,
From where I am,I can see 3 options.
1.Stay where you are on 4.2.2
You just need to flash stock firmware ,and you are back to out-of-the-box state.
But....you want 4.3.... so,
2.Flash a custom recovery,and you have the choice of every custom ROM in the DEV section.4.22,4.3 ,TW,AOSP , you get my drift.As long at it does not contain the new knox bootloader,you can get back to out-of-the-box state in 2 easy steps:
Triangle Away.
Flash stock firmware.
3.Try to flash the new knox-pox 4.3 ROM and be stuck there.(because there is no coming back)
Look HERE
The [OP] explains it well.
And this is probably the ROM you would choose.(close to stock)
It seems the samsung is determined to mess things up for the user who wants to easily mod their own phones.
It has gotten so bad,that the [OP] has even jumped ship to the Z1.
He says he will maintain that ROM,but for how long,because they have already moved the goalposts twice...
I am on 2.
And I intend to stay there,because I like to be in charge of what goes on my phone.
Devs will almost certainly maintain their ROMS,and updates like 4.4 will come along in time.
Only you can make the choice.
Hopefully,I have given you some options.
Yeah, that's the thread I flashed my current 4.2.2 rom from. I saw him throw the towel and decided this just wasn't gonna work.
I guess I need to take the plunge and install Philz recovery.
Somewhat subjective I know but, which 4.3 TW custom ROM seems to work best when the OLD Pre-KNOX bootloader is being kept and with which modem? (I've seem answers vary wildly on this one).

Hi,
The reason you have seen such wild variations on this,is because it is so subjective.
This is where the fun begins.
Trying out different ROMS,and seeing which is best suited to you,and your requirements.
Best advice...read the first post of a ROM,and see if it has what you want from a ROM...especially the bit about new knox bootloader removed.
And remember to make a nandroid!
As for modem,if you are having no issues or signal problems at the moment,stick with the one you are on.

[Q] Upgrade to MK6 modem?

Ok, I'll start by saying that I'm trying to update my rogers 1337m to a custom ROM based on 4.4. The phone came with 4.2.2 on it and the 1337MVLUAMDJ modem. Since having bought it, I rooted it with motochopper, kicked the samsung firmware to the curb, and installed jamal's 4.2.2 google edition rom.
Anyhoo, now I want to install jamal's 4.4 rom. I installed it, but the phone doesn't work. I can't make calls, mobile data isn't working, and I get no bars in the signal indicator. I restored my nandroid backup to 4.2.2 and all is well again - calls, mobile data, and signal reception.
Do I need to upgrade my modem firmware? I have the MDJ firmware, and I noticed that there's an MK6 firmware that seems to be newer. Jamal's rom actually comes with a modem, I9505XXUFNA1, but when I tried installing that with Odin, it said 'security check failed'. I'm guessing that I can only install Canadian modems?
What would be the pros/cons of flashing MK6? Does this unroot my phone? Does this lock my boot loader? I seem to recall that AT&T pushed out an update that locked their users' phones in some way. Is that what I would be in for?

The i337m will never have a locked bootloader. AT&T was never unlocked, we only had an exploit. Updating yours will get you Knox however, i believe. There is a thread of the modems so you can flash just the modem by itself.

I've seen knox before in my process list - when I had the samsung firmware installed, I thought knox was just an obnoxious ( obknoxious? ) policy agent for enforcing exchange rules or something. I've seen neither hide nor hair of it since I installed the google edition ROM, which of course doesn't come with knox. So you're saying the the new modem might have some knox component in it and this might cause problems?

Well if you already had a version with knox it doesn't make a difference. It's just that the newer official firmwares have the knox enabled bootloader and it adds an extra flag beyond the normal system status that would void your warranty on flashes but if you already have it then it doesn't matter. It wouldn't cause any problems, just adds that little flag and I'm not sure if recoveries are made to not trip that flag or what.

As far as I know, Knox is not part of any modem firmware. Someone please correct me if I'm wrong.

It isn't, flashing only the modem packages does not include knox. Using the full system ODIN or Heimdall files will include it if you update the bootloader.

Yes.
First, I don't think that it was strictly necessary to upgrade the modem to get 4.4 - I think it might have just been a problem with jamal's ROM and the kernel he used. Anyways, I decided that I wanted the new modem anyways because I reasoned that it would probably have bug fixes and performance and reception improvements. I was pretty sure that flashing the official 4.3 Rogers image (there is no 4.4 Rogers image) with Odin would give me the new modem. Then I could flash whatever aftermarket ROM I wanted.
Strangely, this didn't work. At least not the way using Odin is recommended. Odin has two text fields pointing to tar.md5 Roms - onw of them is marked 'phone' and the other is marked 'PDA'. As I recall, I had to point BOTH of these at the official Rogers 4.3 ROM get get both the Samsung/Rogers android along with the Qualcomm mk6 modem. I don't think I've ever found a how to where they recommend using both at the same time.
After that, I flashed a Google edition ROM and all is well. And the new modem does seem to get somewhat better reception.
So there is no way to update just the modem from a custom ROM (without wiping everything and installing a stock ROM) for Canadian S4s?

[Q] Just bought my Note 3

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 new on android ... now i using galaxy note 2 ...
the problem phone is got super user ... what i know is my phone was root ...
can i unroot it ??? because i wanna upgrade it to kitkat if can ...
please someone help me ... new on android ...
which country firmware i need to download ???
will my phone brick if i download wrong firmware ???
If you want to unroot fully download triangle away to reset your counter and run it then uinstall superuser. That's pretty much it if you are on stock with stock recovery. If not you can flash stock through odin and it will be back to factory. There is a stock 4.4 prerooted 4.4.2 available which you could flash without needing to unroot

I know it might all sound too overwhelming cause that's how i felt when i was in your situation but reading a lot of threads and gaining as much knowledge i somehow understood what i needed to proceed ahead and flash newer custom ROMS,since you are 4.1.2 and rooted in order to upgrade to 4.3 or 4.4.2 custom roms you don't need to unroot or use triangle away,all you need is custom recovery (philz touch 6.26.0 or twrp 2.7.0) ,you need mj5 bootloader(i'll explain about bootloader in detail below ) and last but not the least backup your current 4.1.2 stock rooted ROM as well as EFS partition.You can visit dr ketan's thread on how to back up your efs incase your imei goes corrupted chances are rare but it has happened with people so backing up EFS is must.Now after you have taken care of 4.1.2 ,you can proceed with flashing a custom ROM,since you want to flash 4.4.2 there are several deknoxed,dedoxed and pre rooted ROM's available by developers and they are just like stock samsung ROM.
Now comes the tricky part and it depends on an individual how he goes about bootloader part. Since you are on 4.1.2 stock rooted ROM your bootloader is outdated,there are few 4.3 Jellybean bootloaders but MJ5 bootloader is the BEST cause it's deknoxed ,meaning it won't void your warranty so even if you upgrade to 4.4.2 you can always go back to 4.1.2 stock ROM ,unroot your phone ,reset the flash counter via triangle away and then take it to service center.If you flash MK4/MJ9 bootloaders which is built in if you officially upgrade to 4.3 you'll be KNOX ,so when you root your phone knox will be triggered and warranty will be null,there's NO WAY currently to reset knox once its triggered. There are no benefits of knox but samsung has its own theory of implementing it for security purposes.Also one cannot downgrade back to 4.1.2 if they flash a knox bootloader you'll be stuck on 4.3 or 4.4 roms
So let's say you flash mj5 bootloader ,then flash the kitkat ROM from one of the links available on xda only draw back being on 4.3 jellybean bootloader (whether its mj5/mk4/mj9) you cannot charge your phone when turned off when on samsung touch wiz kitkat ROM.Kitkat bootloader is available but it's KNOXED which as stated earlier knoxed bootloader will void your warranty but you'd be able to charge your phone when turned off.
I know this is a lot of information at once for you to understand but main thing you should worry about is backing up EFS partition and which bootloader you choose, once you take care of those two things, ROM flashing is easy if you follow the correct steps on how to flash it (mainly making sure you clean your internal memory of phone clean).I am on mj5 bootloader and just this morning i flashed 4.4.2 ROM and everything is running smoothly,no fc no bootloop nothing.

[Q] Should I update from 4.3 JB to 4.4.2 KK ?

Hello
I recently got my S4 i9505. I'm planning to root it
I have Android version 4.3
I used to flash costum roms on my s2 but I'm not really planning to do much flashing on my S4. not soon anyway
So as I connected the phone to Kies to make sure the drivers were downloaded so I can proceed with rooting
Firmware update popped up
I'm not sure what the best option for me now.
Should I root now and then I'd be able to flash a costume KK rom? and are there any stable ones that are better than the stock?
Can I use kies to update my rooted phone?
Maybe I should stick with JB 4.3? Which one is better 4.3 or 4.4.2?
I remember facing some issues when I update my s2 back. So I searched for the KK Update for the s4 and some people weren't so happy with their KK update
I know that doesn't represent the majority but still it could happen to me
So I confused myself
What is your advice to me?
sorry for the long post
Also I have an extra question What is KNOX? and do I need it?

First, the most problems in 4.4.2 are fixed, so if you flash the officical, latest firmware of your country you shouldn't have any problem.
An important thing: if you flash a custom rom, your warranty will be set 0x1, that means, you lost your garanty if you flash a custom rom, that's the so called KNOX. You can use knox like a second system on your phone, with all secure data in it, you can only access with a passwort and all datas are locked without this passwort.
Root your phone after the software update if you want to root it.
