Can I unlock with stock NB4 - T-Mobile Samsung Galaxy S 4

Just swapped over to tmo today and picked up an S4 with NB4. I know it can be rooted, but can I unlock the bootloader and flash a custom recovery and roms? I know about tripping the KNOX counter, but I don't care about that.

Bootloader is not locked, so in other words yes

Sweet! Is there a guide to doing this?
EDIT: Nevermind. I didn't realize it was as easy as installing Rom Manager/CWM recovery.

Yup very easy

[Q] clockwork mod removal

I rooted my friends S3 ATT with the s3 toolkit v7.0 he now wants me to unroot it so he can take the 4.3 update it have run the unroot and remove zip multiple times ( I even re rooted it and tried removing it again) and it will not remove clockwork mod recovery even though it says it will, it has successfully unrooted it the phone and removed super user and busy box . he does not want to loose all the data on his phone is there another way to remove clock work mod and get him back to the stock recovery so he can take the 4.3 update with out using triangle away ?
thanks
You would need to flash the stock recovery to replace CWM.

where do I acquire a stock recovery and is it flashed through oden or through clockwork ?
thanks
I'm not sure where to find the stock recovery as I have never seen one that is flashable via Odin, CWM, or TWRP.
By updating to stock 4.3, the phone will have a bootloader that cannot be downgraded and Knox will be installed.
I personally avoided the 4.3 update because the 4.3 bootloader makes it tough to go back to stock and tripping the knox counter will void the warranty. Also, knox can interfere with root access.

[q] 4.3 jellybean ota questions

I've got a Galaxy S3 I747 it is currently running 4.1.1, I747UCDLK3 Baseband. I'm not exactly a noob when it comes to flashing and rooting, I know my way around CWM and Odin pretty well. But I have a few questions on this 4.3 OTA. (I am a forum noob)
-Will I still be able to root? (I heard CF works for it)
-Can I install CWM? (Is the Bootloader locked??)
-Will I be be able to I flash other roms than the 4.3 TW like CM11Snapshot? (Is the bootloader locked?)
-What the h*ll is knox and why should I be worried?
-What is with the boot loader downgrading thing? (Have to do with locked bootloader??)
I AM NOT AT ALL WORRIED ABOUT A FLASH COUNTER OR VOIDING A WARRANTY I AM NOT ON A CONTRACT . I JUST DO NO WANT TO HARD BRICK MY PHONE.
If you take the OTA 4.3 update, it will install Knox and the 4.3 bootloader.
The 4.3 bootloader cannot be downgraded and attempts to do so will probably brick the phone.
You can root the stock 4.3 ROM with auto root but Knox may interfere with the process of cause issues after the fact.
You can still install CWM. I rrefer Philz Touch which is CWM-based.over TWRP.
So can I still flash roms?

Yes, you can flash ROMs. Is your phone unlocked? Since you're on 4.1.1 stock, you can unlock it for free.
Personally, I avoided the 4.3 update because it installs knox and the 4.3 bootloader which can cause problems when using Odin to get back to stock.
I have a Canadian version of the s3 and I'm able to run KK ROMs with a stock 4.1.2 bootloader.

Unlocked as in Bootloader? Yeah I've been able to flash roms via CWM and Odin on 4.1.1 and as in Carrier unlocked? Yes I use Straight Talk on this ATT S3
If I got the 4.3OTA I wouldn't need Odin to go back stock if I flashed a ROM would I? I could just make a back up via CWM then restore later if I wanted right rather than using ODIN?
See I can't use KK roms because I have the 4.1.1 BL so is there a way I can upgrade my boot loader to the 4.1.2 version??
Would I lose my carrier unlock if I upgraded to 4.3 or if I upgrade my bootloader??
I suggest downloading a ROM you want to try, then unzip the ROM and look at the updater script to see which bootloaders are supported. The updater-script file is located in \META-INF\com\google\android\updater-script. You can use a text editor to open the updater-script file.
The first few lines will list the bootloaders that are supported. I run Validus which is a KK ROM using a stock 4.1.2 i747m bootloader.
Do you know about this > "If I got the 4.3OTA I wouldn't need Odin to go back stock if I flashed a ROM would I? I could just make a back up via CWM then restore later if I wanted right rather than using ODIN?"
Also couldn't I just upgrade my Bootloader and Modem from here?

I feel like if I upgrade my boot loader then I won't have to worry about restrictions.
Would I lose my carrier unlock if I upgraded to 4.3 or if I upgrade just my bootloader??
I ended up flashing the MG2 Modem and Bootloader, I'm good now, also if I want 4.3 I saw loserskater has a leak version that will be good and wont not let me downgrade my bootloader.

How do I flash with mobile odin

Can I ask...
I've been reading thru some of these threads, and I'm coming to the conclusion that even with KitKat the bootloader is still unlocked, is this true? I have at&t version and they started locking that down with 4.3 JB.
Thanks.

This caught my eye. How is that possible with the bootloader unlock, is that just for AT&T? I am on T Mobile GS4 running 4.3 and I can see the knox counter on it 0x0 and I was informed that once updated from 4.2 to 4.3 and above the bootloader is now locked. Please clarify I would like to know. I am rooted though on stock through using this forum and have not tripped knox using this method. http://forum.xda-developers.com/showthread.php?t=2565758
I would love to find a way to install CWM without tripping the counter and trying other roms again but I here I can use bootstrap to run a custom rom, but no word on getting CWM installed without tripping the counter......unless I am wrong and I hope I am!
Thanks,

I think you have a definition difference. The bootloader is unlocked on the TMO S4. That is you can use the bootloader to update and install modems, roms, recoveries, etc. It is not locked and will let you do this.
However, if you use the 4.3 and above bootloader, it will set a flag if you flash a recovery. This is known as the Knox Warranty flag. And, this is what is shown on the ODIN or bootloader screen.
BTW, if you update to NB4 (Kit Kat) with a 4.3 bootloader or later, the SafeRoot method will not work. The only known rooting method at this time is the CF-Auto-Root which will trip the Knox flag. So, if you are fully stock 4.4.2 you will trip your Knox flag if you root the phone.
However, you can do it. It doesn't lock you out of doing it. It just records that you've done it.

So if Knox counter doesn't matter you can still root device..are you still able to install custom roms? or isn't that possible ATM? Trying to get rid of the severe lag 4.4.2 OTA update has bestowed upon my gf's phone.

You can flash anything you want with the TMO S4.
However, if you need to return it for warranty, they MAY check the Knox flag, and they MAY not do the warranty service for free. That hasn't been shown to be a fact, but it is the reason for the flag in the first place.
It has been stated by a few people that re-flashing back to full stock will remove the Knox flag. I cannot verify it, since I haven't tried it.

Can anyone shed some light on a couple of points? I currently have the MDL bootloader along with the NB4 modem. This all runs fine with my daily driver (LightSpeed) 4.2.2 ROM, as well as the (Insane Kit Kat) 4.4.2 I've been experimenting with. I do understand that I can't go back to the MDL bootloader if I update. Knox issues aside, is there any actual advantage to having the new bootloader? Since my warranty is running out soon anyways, I'm not too worried about tripping Knox. So, does the NB4 bootloader offer any real performance or feature advantages? Can I still run 4.2.2 or 4.3 ROMs with it, or will it limit me to 4.4.2+ ROMs? Does it impact the usage of different kernels? Thanks!

It won't remove the Knox flag although they MAY not check it or they MAY when I did my warrenty return they did not but that doesn't mean it will always be the case

If you don't care about knox you better off going to the new bootloader ,the NB4 wifi driver is not present on the MDL bootloader so you still using the old wifi. I notice very strong wifi signal after upgrade to kitkat bootloader to flashed modem and wifi fix.The best way is to flash the NB4 firmware through Odin so you can get everything needed and go from there.
Thanks, makomek. I've been wondering about that, but haven't really found much info beyond the Knox implications. I have gotten an improvement in general phone call stability and download speed with the NB4 modem. Is what your're talking about related to the NON-HLOS.bin being installed? As I recall, that was to improve LTE, but I apparently it's actually related to WiFi. Or could be both? At least it's good to hear there are positive reasons to update the bootloader. Any idea if doing this would lock me into only using KitKat ROMs/kernels, or would 4.2/4.3 still work? Your input is much appreciated.

If your girlfriend's phone is stock, unrooted, and she took the OTA, the easiest way to get rid of lag is to factory reset. If she doesn't care about being rooted and just wants the stock rom, this is the easiest way to improve performance. Just start over. OTAs, in my opinion, are like a dirty flash.

[Q] 4.2.2 Roms after Knox is tripped?

So I recently used CF Autoroot to root my T-Mobile GS3 SGH-T999 and I heard that if you try to downgrade to android versions before 4.3 your phone will be hard bricked. So with my knox counter tripped I was wondering can I flash a rom that is on 4.2.2 I want to flash the MIUI rom. Thanks in advance.
You can flash any custom Rom via Custom Recovery. Nothing bad will happen as they have only Rom and Kernel.
However just never flash Pre-4.3 Samsung firmwares via Odin. Those contain the older bootloader. If you tried to flash older bootloader, you get hardbrick.

I know to get rid of the trip count I used triangle away. I installed, opened the app, followed the set up, reboot and count was back to zero.

[Q] What should I do to not flash KNOX bootloader?

Hi guys, I'm getting this phone from someone and I want to know that if the phone came with 4.1 without KNOX bootloader what can I do for precautions to not flashing KNOX bootloader?
or, if the phone is came with 4.4 with KNOX bootloader how can I remove it? thanks.
The question should be if you still need to bother about KNOX? THe warranty is probably over and if you have lower bootloader, then flash MJ5 and ROM without KNOX and prerooted like OMEGA, which I recommend. If you have newer bootloader then just flash whatever you want and forget about KNOX

so there's no way to remove the knox bootloader right? So if I got the old bootloader, should I flash MJ5Patch?

If you get bootloader older than MJ5, flash MJ5 bootloader, it is the last one that works with 4.3/4.4.2 that is without KNOX. If you get it with MJ5, no need to do anything. If it's newer - you'll just have to live with the fact that Knox flag will be set to 1.... (if you want to flash custom ROMs)
