[Q] ODIN flashing older rom.

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.

Hmm i think then yes i might have knox. I think at one point i might have been on stock 4.3 is there any way that i can check to see if i have knox? And if i have knox i cant flash an older stock firmware for my s4?

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

It would have been interesting to at least try some new test in the process - for instance I have seen some intriguing reports from N900W8 models where they have apparently installed some version of xnote (custom rom pre-rooted) without tripping knox presumably by somehow using stock Samsung kernel and stock Samsung recovery (I repeat, that was THEIR claim, not mine, but more research and testing on the subject would be nice).

I'm one of those people. I installed the Mexican update, then rooted using Cf autoroot, then installed CWM and flashed X-Note with Katturbine kernel and I'm still knox 0x0 :/

I am also on MJ7, N900t and I had have two questions if possible.
1. Do you recommend me to upgrade to kitkat then to have custom rom or just to root my 4.3 then to have a custom rom?

2. Can you please explain what you did step by step instructions to what you did, and if possible providing a link to the Mexican rom you referred to and the same CWM you used.
Thanks

That sounds very different from what I was expecting, and so far based on that I would say that it mostly seems to be a result of the N900W8 bootloader system rather than something very special that needs to be done when flashing stuff
Question specific for N900W8 - is it possible to downgrade MJ4 -> MJ1 on that phone? (since that would confirm that the W8 bootloader is quite different).

Root GT-N7100<4.4.2> without tripping KNOX

Hi XDA people,
Just found this workaround for rooting latest 4.4.2 stock firmware without tripping Knox.
This method downgrades the firmware(System & Kernel) on your device to N7100XXUEMK4 except for the bootloader.
Dont even try to downgrade the bootloader as this isn't possible.
What you need:
1.Odin v3.09
2.Stock official N7100XXUFND3 firmware on your device.
3. A device with Knox Warranty Void: 0
Procedure:
1.Download N7100XXUEMK4 Stock Rom from HERE
2. Open the downloaded file.You will find 4 .tar.md5 files and an Odinv3.09 zip file inside.
3. Extract the Odin file and setup Odin on your PC.
4. Next extract the file named AP_N7100XXUEMK4_2099172_REV04_user_low_ship.tar.md5
5. Load this file into AP tab on Odin. Connect your phone in Odin mode and flash this file.
( Note : You have to flash only the AP file from Odin. Do not flash the other files namely CP, CSC, BL)
6. Now once the phone has rebooted go back to download mode and check if Knox has tripped or not.
7. Next use Saferoot from HERE to root your device.
(You would find the guide on how to root using saferoot easily over HERE
8. Now if saferoot was able to root your device then you must be rooted without tripping Knox. :good:
9. Now you can easily flash your official firmware through mobile odin. Select Everroot option on Mobile odin while flashing the new firmware. In this way you wont lose root access.
Known Issues:
If after rooting you want to flash custom recovery via mobile odin, or via DR.Ketan's utilities app please note that it will trip knox.
Knox remains cool until your recovery is stock. The moment a custom recovery is detected knox goes 1.

Cant you just do this?
Use Mj5 bootloader and any rom 4.x
Flash Kitkat 4.4.2 via mobilOdin and root.
Make sure status is ok (use triangle away if not)
Flash latest 4.4.2 bootloader via Odin (pcOdin)

Surely it can be done that way.
This is for those who already upgraded to the newer builds.

What i mean was use Triangle away before you flash the 4.4.2 bootloader to get official status and binary count 0, the knox in MJ5 always stand 0.

I don't think flashing ND3 BL will trigger knox.
Most of the users already flashed ND3 BL from MJ5 while they were on DN3. It doesn't trigger that way.
And yes about that guy, he never mentioned any detail that he downgraded from ND3 to which firmware of 4.3.

I did read them. They got knoxed means they got a BL with Knox warranty Void 0. And @paarkhi confirmed it to me
And I really don't think it would trigger knox that way because the bootloader doesn't check the integrity of the firmware on your device when you're flashing the bootloader itself.
Also it doesn't trigger Knox while it boots up the system and finds unauthorized firmware.
Because we don't have Kernel lock and secure boot like on Qualcomm based N3.

Okay this is all too much for my brain to absorb at this time of the night ,i don't think i actually understand the difference between Knox warranty void and being Knoxed ,i guess since we install de-knoxed ROMs we can't get Knoxed ,just that our warranty goes out the window and we cannot downgrade beyond a certain OS right? If what i stated is wrong then i'll go to bed and dream of knox

Lol. It's paritally right.
Don't worry buddy I'll help you learn Knox
Being Knoxed is getting that extra line in the download mode.
But this doesn't throw away your warranty. Warranty is lost only when this extra line in download mode ends with 1 instead of 0

No feedback yet. But one thing i can say for sure that even if this method fails it won't hard rick your phone because we ain't downgrading the BL here.
And I found a similar method on S4 active forums. It seems it works very well.

Yes it would trigger by flashing unofficial firmware.
But here we ain't doing that too.
We're just flashing a older kernel+system partition (the whole PDA from MK4) that was vulnerable to root without tripping knox.

KNOX WARRANTY VOID on the GT-I9506 (Galaxy S4 LTE-A)

From reading around on the forum and asking on IRC I have tried to figure out exactly how KNOX works. This is my conclusion, but I am far from sure this is correct.
If someone can give me more information, I would be happy
On a GT-I9506 with the stock 4.2.2 bootloader, using ODIN to flash custom software does not do anything special since the 4.2.2 bootloader does not contain the KNOX functionality to burn the e-fuse.
On a GT-I9506 that has been upgraded and has the 4.3 bootloader, using ODIN to flash new unsigned software will burn the e-fuse.

Semi-correct, with 4.2.2 bootloader you doesn't have knox, but with 4.3 bootloader you have knox, but you can flash a new official rom with Odin without affect the knox status. It only will change to 0x1 if you flash something unnoficial with Odin, like a custom recovery, kernel, root, etc... but know you can root in 4.3 wirh towelroot.

Galaxy S4 [i337m] ROM update help

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.
The sgh-i337m forum is here: https://forum.xda-developers.com/galaxy-s4-att

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.
