So, all of the files that begin with BSDIF apply fine with the android applypatch utility I built from the AOSP source tree. Samsung appears to have made some modifications to their utility to also do sparse patching as well as regular bsdifs. I'm looking into doing to patches on the device while writing the outputs to the filesystem rather than the actual bootloader, or getting the sammy utility to run in a chroot in an arm environment. :D
[T-Mobile Samsung Galaxy S 4] neocorteqz:
I'm assuming that this line in the instructions linked from the site in the op

"Click the AP Button, and select that CF-Auto-Root-jfltetmo-jfltetmo-sghm919.tar.md5 file that you get in Step 2. "

Means PDA Button? cause I don't see an AP button anywhere. And of course the only other accessible button is the Pit button.

then again I don't recall a AP button ever existing in Odin.

Thanks.

[T-Mobile Samsung Galaxy S 4] widto08:
Just to clarify...

I see that you state that you are still on the 4.2.2 BL even after updating the non-hlos.bin.

By your statement above, are you are saying that flashing these two files will

NOT

update to a knox enabled BL as it did on the 4.3 non-hlos.bin.

I've Odin'd the NB4 modem.bin successfully and it's working fine.

Looking forward to clarification on this as I, and I'm sure many others, do

NOT

want anything to do with knox.
[T-Mobile Samsung Galaxy S 4] Fenny:
I can confirm that my BL does not show anything about Knox whatsoever. It is possible that the non-hlos is simply being rejected when the Odin flash completes, but I don't believe that it is.
[T-Mobile Samsung Galaxy S 4] OGPackin:

[T-Mobile Samsung Galaxy S 4] widto08:
Update

Just to update...

I'm currently on stock rooted 4.3 ROM.

Updating to NB4 Modem, all works as it should. (this is my current phone state 4.3 w/NB4 Modem)

Updating to NB4 non-hlos.bin causes loss of sound. I can confirm that it does

NOT

update to the Knox BL but not having sound is a no go for me.

If this happens to you, to get sound back you have to Odin back to MDL Modem.tar file that has the MDL non-hlos.bin file included (this is what I have and what worked) then proceed to update to NB4 Modem without updating the non-hlos.bin file.

Tried it 5 times and lost sound every time :(
[T-Mobile Samsung Galaxy S 4] j_r0dd:
The non-hlos.bin needs to match the bootloader.
[T-Mobile Samsung Galaxy S 4] widto08:
Not according to Fenny's statement above. May be due to ROM as I'm on stock TW 4.3 and Fenny is on GPE.

Just posting my results, I have no idea if it is indeed dependent on BL or not.
[T-Mobile Samsung Galaxy S 4] j_r0dd:
Definitely not the rom. It may work with a post-Knox bootloader but I guarantee it will not with a pre-Knox bootloader.
[T-Mobile Samsung Galaxy S 4] HampTheToker:
I lost sound as well attempting to flash non-hlos.bin.

I'm on Dan's 4.3 GPE rom with MDL bootloader and NB4 baseband (previously MK2).
[T-Mobile Samsung Galaxy S 4] Fenny:
Nope sad to tell, but you are incorrect on that point. :D

[T-Mobile Samsung Galaxy S 4] Fenny:
Good to know. Sounds like the GPE uses it in a different way.

Do not flash NON-HLOS unless you are on GPE or have the knox bootloader already. It won't upgrade the BL but you will also have no sound unless you are on the GPE.
[T-Mobile Samsung Galaxy S 4] j_r0dd:
That is interesting that it is working for you on GPE.
[T-Mobile Samsung Galaxy S 4] Fenny:
It kind of makes sense. I bet that the vendor put in a workaround for both Google and Sammy with the 4.4.2 releases. Why remove code from your build tree? Though they very reasonably could have disabled it using ifdefs... I'm just happy that they didn't. :)
[T-Mobile Samsung Galaxy S 4] HampTheToker:
I'm on GPE and had issues with it.

Maybe, because I'm on 4.3 GPE instead of KK?
[T-Mobile Samsung Galaxy S 4] Fenny:
I suspect that is the case... that is unless odin cowardly refused to flash the NON-HLOS and didn't have the decency to let me know about it. ;) I eagerly await a report disproving my little theory.

Mobile Odin is ran like an app. So, by default, you can't be in download mode. I personally like the old fashion way, Odin thru my PC
[T-Mobile Samsung Galaxy S 4] access9:
Happened to me too. Then I flashed it again (via PC Odin). When it was done I reboot immediately back into download mode then flashed the modem again. Only then did my baseband change from MK2 to NB4.
[T-Mobile Samsung Galaxy S 4] orphan203:
So just flash modem.bin twice? What about the non-holis file?
[T-Mobile Samsung Galaxy S 4] HampTheToker:
Skip it unless you're on GPE 4.4. I'm on 4.3 and it borked sound and such.

Quick Odin instructions for those of you having issues:

After the first flash in download mode just hold down power until the phone shuts down, then press and hold volume down and power (you don't have to hold the home button) until it boots back into download mode. Flash modem.bin again, then hold down power until the phone shuts down again. Unplug, power on, and check your baseband after it boots.
[T-Mobile Samsung Galaxy S 4] Romcrazguy:
Finally got it to work ... The instructions are not explained properly for anyone having difficulties make sure your phone is in download mode the first time around flash modem.bin and do then go back to download mode again and re flash for the second time ...then profit ?
[T-Mobile Samsung Galaxy S 4] norml:
Little tip, turn your phone off and then go into download mode(press power+vol. down) when flashing via Odin. Tend to stick better this way

You can't because you have to be rooted to have custom recovery. I think you're supposed to be on stock MK2 and you do it in stock recovery, install from ext sd or whatever. Do a search, I don't plan on upgrading this way, but I've read enough to know that much. Just read the forum.

Thanks. I'm no Dev, so I didn't want to ask this in your new thread over at Android Dev. Hope you don't mind if I ask here:

Why do you recommend staying on the MDL boot loader? Simply to avoid Knox installation, so as to avoid the Knox counter tripping, so that the warranty isn't voided? Or is there a more insidious aspect of Knox that I'm not aware of? Thanks.
[T-Mobile Samsung Galaxy S 4] gaww:

[T-Mobile Samsung Galaxy S 4] Fenny:
Well for one thing, you can't downgrade once you have upgraded. So, for instance if you decide that you want to go back to 4.3 or 4.2.2 you cannot fully revert. I am not about to advise updating to a bootloader unless there is a very good reason to lose that ability to downgrade.
[T-Mobile Samsung Galaxy S 4] Dr. Fed:

[T-Mobile Samsung Galaxy S 4] Dr. Fed:
To Fenny or anyone who knows, I just want to clarify. When you say that once you upgrade to a Knox-secure bootloader, you cannot downgrade, what exactly can we not downgrade to?

After reading about it, I came to the conclusion that once we go Knox bootloader, we cannot downgrade to a pre-Knox bootloader. Bootloader only. For example, if we are on the MDL bootloader, I thought we can Odin flash TW Knox 4.3 official, update zip (in stock recovery) to TW Knox 4.4.2, still root, install custom recovery, and still install a custom rom through recovery that is Android 4.3 or 4.2.2. The Knox counter would then read 0x1, the warranty would technically be void, but we would still be able to jump to different versions of Android. I thought the only unchangeable things would be the bootloader and, because they are tied to the bootloader, we would have to use the latest LTE and GSM modems to have a fully operational device (for working sound, wifi, data, etc).

But, one could interpret Fenny's statement of "you can't downgrade...back to 4.3 or 4.2.2" as not being able to downgrade to a previous Android version rom.

So which scenario is true?

In addition, I read that once the Knox counter is tripped/blown/0x1, it is impossible to Odin an official firmware, whether it is an older version or a new version. Is this true?

Thanks to everyone for their help, I appreciate it and I'm sorry to be a pain in the arse. Knox has been a tremendous source of confusion and misinformation.
[T-Mobile Samsung Galaxy S 4] imanoobfml:
4.2.2 or MDL bootloader is pre Knox. After doing the 4.3 OTA which would give u the MK2 Bootloader with Knox, you can't go back to MDL. MK2 has the Knox counter thing and MDL doesn't. The way I see it, is if you're out of warranty then it shouldn't be a big deal. Also my Knox counter is 0x1 and I still odin'd stock 4.3 without an issue. I was on the MK2 bootloader so I can't speak for people on MDL.

Sorry if I didn't answer everything... You wrote a lot.
[T-Mobile Samsung Galaxy S 4] Dr. Fed:
Thanks for the input. So you must have Odin'd the stock 4.3 so you could update to TW 4.4.2. Yes? And if that's the case, I wonder if an attempt to re-Odin the stock 4.3 would now fail.
[T-Mobile Samsung Galaxy S 4] imanoobfml:
Yep that's correct. I've been meaning to try flashing the 4.3 stock again through odin. I'm not sure if it will fail or not. 4.3 and 4.4.2 both have Knox, I don't see why it would fail but you never know until you try. I'll get around to trying it later tonight tho.
[T-Mobile Samsung Galaxy S 4] Dr. Fed:
Good luck. Some have reported that the secure bootloader of 4.3 prevents Odin-flashing back to 4.2.2, which makes sense since Knox isn't a part of the MDL 4.2.2 build. But we'll see if the newest Knox 4.4.2 secure bootloader prevents Odin-flashing Knox secure 4.3 (reverting).

Any other input is greatly appreciated.
[T-Mobile Samsung Galaxy S 4] HeavyA:
I'm still on the MDL bootloader with the MK2 baseband. (No Knox).

[T-Mobile Samsung Galaxy S 4] LuigiBull23:
Some have been able to flash the entire NB4 modem (modem.bin + NON-HLOs.bin) without issues while others have needed to flash just the modem.bin file to prevent sound corruption. It's hit or miss really.
[T-Mobile Samsung Galaxy S 4] Dr. Fed:
Yes you can, only the GSM modem (not LTE)

Follow Shiamatsu's guide here:

http://xdaforums.com/showthread.php?t=2678774

I haven't done it yet, but its been confirmed to work. The modem must be flashed twice in Odin, refer to the guide. This will give you NB4 GSM modem while still on the MDL bootloader.

Note: this is the modem file that Fenny put together, not an official modem package, but official in that he used the update to "create" it.

Additional note: LuigiBull probably knows better than me.
