Hi guys!
My dad has been using the above mentioned device for the past 5.5 years. The device is running a stock rooted 4.2.2 MDJ build. His bank is about to stop the support for the 4.2.2 version so we need to update the OS. The minimum required OS is now KitKat but I would like a more moderate ROM. Is it possible to have for e.g. an Oreo based ROM without Knox? In other words, do some ROMs include a Knox bootloader (to enable them to run)?
Thanks for the help!
Only Samsung ROMs would contain Knox.
The apps should be fine with a stock 5.01 ROM if you want to stick with stock.
If you want to run a custom Oreo ROM, I suggest flashing the latest bootloader and modem before installing Oreo.

Thanks for the reply!
As I said I would like to evade to flash the Knox bootloader. I know Samsung made it impossible to use their OS without Knox so I'm guessing my only option is to use custom ROMs. Are there any ROMs that still utilise the old bootloader?
You can't flash any bootloader other than stock.
Knox will not interfere with flashing custom ROMs.
Some banking apps will not work with a rooted ROM so you may have to use another app to hide root.

Root is in place just to disable OTA and by the looks of it the banking app doesn't care.
Regarding Knox, I actually think of it as a security downgrade because the NSA played a part in its development and they are known to spy on people. I feel safer when it's not installed LMAO
Is the phone an sgh-i337m or sgh-i337?
The sgh-i337 was made for at&t.

It's the SGH-I337M. Canadian model. CSC is TLS (Telus)
Okay, just wanted to make sure it wasn't the att model because the 4.3 or newer bootloader is locked on the non-m version.
Anybody have any suggestions for a ROM? It doesn't necessarily need to be the latest version of Android. It just needs to be compatible with the old bootloader
If you're still on MDJ stay on MDJ, don't update your bootloader, only the modem. 4.3 don't have KNOX, just don't update from OTA.

Don't worry. I won't I am just looking for an at least 4.4 ROM without Knox
AFAIK Knox is on the 4.3 build
Here are a few pics if some of you still don't believe me
Anyone?
Heard also Chrome is losing support for Android 4.2.2

Hey guys so i have heard that if i install the old firmware for my s4 from sammobile using Odin one from early 2013 that it will give me access to service menu so that i can unlock my phone. So my question is that is it 100% safe to Odin flash the older 4.2.2 rom when i am on 4.3? Can i flash it unlock my phone then upgrade my phone to a custom rom again? Thank you

Do not do this. This will brick your phone. If I am not mistaken, there is a method to unlock mk2 in the general section.

You should ask this in the t mobile s4 forum. I believe your bootloader is unlocked and you can flash an older firmware version. But check there first. This is the att s4 forum. It can't be done on the at&t s4.
Is the service menu missing on the stock T-mo 4.3 ?
Nooo guys i have an unlocked bootloader i have the s4 that is very similar to the tmobile and it's the same as the Canadian versions. And yes the Canadian version which is 1337m and mine which is m919v don't have access to service menus but i have flashed a lot of custom roms simply by philz recovery so doesn't that mean i have an unlocked bootloader?

If you're on 4.3 I believe you also have Knox, in which case I don't think you'll be able to go back to 4.2.2. Read through this http://forum.xda-developers.com/showthread.php?p=40903040

Did you ever take the ota to 4.3? Do you know what firmware your device is on? A 4.3 custom Rom wouldn't have knox but if you took the official update to 4.3 you would have Knox.

Idk, I'm not that familiar with your device. From the little bit of reading I've done I would say no, you can't flash an older firmware. But again, I'd post this question in the t mobile forum. They'd be more familiar with your device.

Did you ever update you device with kies or ever take an over the air update ? It's fine if you were on a stock based 4.3 rom as long as you never took an official update. If so then you can't go back. Just flashing a stock 4.3 rom won't change that status but the 4.3 bootloader would.
You would have know by checking in settings under SE

I remember i soft bricked my phone one time and had to flash my firmware but the 4.3 latest one from sammobile and after i did that i got knox but i believe i already tripped the knox counter because in download mode it says 0x1 so i guess i cant?
What is the difference between devices hltetmo and hltecan? I have a hltecan. Will we need CyanogenMod compiled for hltecan? I notice that recoveries have different versions for both devices. Also I am wondering about downgrading for 4.4 (when it comes) to 4.3. Is there a surefire way to upgrade and downgrade between 4.4 TW 4.4 CM and 4.3TW? I would not mind voiding my Knox counter. Just worried about being stuck or getting a brick for another 21 months on contract :silly:

I played around a bit earlier... The only firmware you can upgrade to 4.4.2 and downgrade back to 4.3 is the mexican telco one for the n900w8, however I had some issues but will play some more tomorrow when I get time. As for KNOX, it's just one of them things we have to live with I'm afraid..
EDIT: I'm gonna mess with the bootloader and see, doubt it can be matched/mixed to work with the N9005 but what's the harm in trying.

CM is based on MJ/MK Bootloader. You could run Android 9.6 and it'd make no difference. It's all about the bootloader

Sorry. Can't understand exactly. What exactly means what versions you can run with a new bootloader?
MJ7 is the bootloader that powers CM currently. You need a bootloader to be able to boot into the operating system. Like a key into the phone.
If you upgrade your bootloader to a newer version aka NA6 it locks the phone. Therefore anything that runs lower than NA6 aka MJ7 won't work.
Think of it like, you broke your door, you got a new door and tried to use the old key. It no long works.

hi, can you elaborate?
i always thought samsung doesn't let you downgrade to an older bootloader. but if you install CM (not samsung official updates) the bootloader doesn't get updated so you can downgrade in the future.
unless you upgrade to 4.4.2 official samsung ROM and update the bootloader, then you'll never be able to downgrade again?

Currently have a AT&T S4 rooted with MDL firmware. I have flashed other 4.3 loki roms without any problems (using Goldeneye 20 now). From the reading that I have done on the forums, it is my understanding that certain roms require a newer firmware version, for example, Hyperdrive. Is that a correct statement? If so, will that continue to be the trend with later releases? Can anyone provide any additional information to help me understand this better? Thanks in advance!

For MDL, that does not apply. Basically people with MF3+ phones need to upgrade to 4.3 to have 4.3 ROMs. All you need to do is continue to use loki and never upgrade your bootloaders.

Unless he wants a 4.4.2 rom then he needs the new bootloader....which is locked! so stay away of 4.4.2 for now
Flashing roms (unless stated by OP) will not update your bootloader correct? Since I am one of the lucky ones to have the MDL, I don't want to jeopardize it.

Not true, he can flash a 4.4.2 ROM with the MDL bootloader as long as he gets a loki 4.4.2 kernel. Otherwise the 4.4.2 Google Edition thread wouldn't get much attention

Flashing ROMs will not touch your bootloaders. Just never take any OTA updates to the stock ROM, and never ODIN any firmware except MDL. OTA updates on custom ROMs will only work in some cases (GE doesn't because they're ported from a different model, Hyperdrive will because it has a specialized system).

The Stock Rom rooted with old bootloader would be great.

You can grab any 4.2.2 formware from sammobile. Those shouldn't have knox in the bootloader.

Okay, sry it seems that I was a little bit wrong, the MGG build is the first 4.2.2 version with the new knox bootloader, but it is still correct that MGA is the last build with the Knox free one.
On my german sources they told that MH1 build is the first Knox version but however. Take a look at this

Knox has been introduced in Oct 2013 along with 4.3 bootloader (as far as i can remenber! one year old.....)
So your request is to come back to a 4.2.2 rom version, why? just to avoid Knox? OK I understand
But In my view you have better to flash a recent 4.4 CUSTOM rom that will preserve your legacy bootloader and will offer all the upto date features. They are many available in the dev section.
Custom Roms do not modify the boot section , so no risk to become knox pointed.
Thanks to Darker Times for his links.
Hey guys, everything I've read has said once you update beyond 4.3 you can never go back down because of knox. I also saw someone mention you actually can downgrade to a custom ROM based on a previous build just not to stock. Can anyone clarify this for me? I'm not worried about breaking my warranty since it's long since expired. I'm on the rooted 5.01 Goldeneye ROM and want to go back to a 4.2 ROM. strictly for tethering purposes
What is the model # for the s4?
It's the AT&T sgh-i337

I can't recommend any 4.2 roms as I don't have the phone. Also, I don't think such an old rom will work on an lp modem and bootloader.

You can try but I don't think you will have a functioning phone in that the imei will not be properly displayed which means the phone wouldn't be able to connect to the carrier.
