Do you recommend to upgrade bootloader? - Galaxy S 4 Q&A, Help & Troubleshooting

Hello mates, I have a question.
Which of you are in the latest bootloader?
I want to upgrade, usually with new bootloader there are some enhancements but reading about that KNOX thing that Samsung added to the bootloader. Also I think that that's just for warranty (I void mine at the first minute jajaja), I've never used TouchWiz and I read that the you can't revert the bootloader, as usual, so I want to be sure that I will be able to keep flashing things and use Odin as well, since the counter can't be reset.

I've got the new bootloader and flash a lot.
I'm currently running PAC ROM and KT Kernel with no issues at all
If you have new bootloader it does void warranty forever if KNOX WARRANTY VOID 0X1.
You can't downgrade firmware in Odin but you can upgrade

In any case if we want to upgrade to TW 4.3 next October I suspect all of us must use the new bootloader...

That's what I was thinking, besides since the KNOX feature is just for warranty purposes and I been using an AOSP ROM since the first minute.
But, are we going to be able to use Odin without any problems?

This is what I'm not so sure about, everyone is saying different things!
Some say once you trigger the KNOX flag then you can't use Odin at all. Some say you can but only to upgrade firmware, not downgrade. Some say you can but can never use stock kernel again as it checks the KNOX flag and won't boot phone if it's 0x1.
I think before you take the plunge, do some reading and research to be on the safe side

Could someone please clarify a rooting/firmware rollback question

Have updated my stock I9505 to JDQ39/MH8 and was wandering if I were to root and install something like CM10 or GE 4.3 rom, I will be unable to rollback to stock TW 4.2.2?
Sent from my Nexus 7 using Tapatalk 2
Of course mister you can. Why not?
But keep in mind that you can rollback only on MH8 stock firmware and not on previous cause new bootloader.

That's great. Thanks. Just wanted to make sure I could go back to stock touchwiz should any of the rooms not be for me.

your warranty will be void
and for now you cant roll back to warranty, knox warranty void counter will show 1 and there is no way to reset it so far
This has become a bit of a pain hasn't it. Think I may sit this out untill a workaround is sorted.

Apparently the new counter can't be reset, so once you do something to change the system (root etc) your warranty will be voided. For ever.

How can I check Knox counter?
[[]]
If you've updated to the new firmwares, just boot into download mode. You'll see it there.
Thing is, Chainfire said that it is based on an e-fuse, so it can't be reseted.

[Q] Knox, odin, root and warranty

I've updated my N9005 via OTA to the latest XXUDMJ7.
Can I flash a previous original rom like XXUBMJ3 via ODIN and then apply root de la vega?
Or this flash via ODIN will trip the knox flag to 0x1, even being an original rom from sammobile?
Now that I'm on XXUDMJ7, how can I root my N9005 without losing my warranty?

No, you cannot downgrade since you have MJ7 bootloader.

I would like to warn u about the hazards if rooting with the Note 3.
Knox invention by these south koreans is just a pain for all those rooters inc. Me.
Watch the reactivation lock, it can brick ur phone if u downloaded and installed the wrong kernel. It happened 2 me. Ive lost a brand new Note 3 because in download mode with odin i couldnt get in because it was locked !
Note 3's reset their bioses each time. It takes one heck of a good programmer to bypass this awfull but very effective manner of theirs.

Hi mate if you dont see any knox warranty void 0x0 0x1 in download mode. Means ur still on old bootloader and thats a good sign. Turn off your phone manually and press power+volume down in order to reach download mode to check it out.

I apologize for bumping this, but I am on stock 4.2.2 rooted right now and I don't have this knox warranty in download mode. It only says my system is modified and TringleAway can solve that. Does this mean if I update to 4.3/4.4.2 then this flag appears? Because from what I've read there is no way to downgrade to older bootloader/reset the flag to 0.
Hello,
flag in the new bootloader change only if you flash a kernel or a recovery stock.
For the root, it's possible to keep 0 x 0
But if you upgrade to 4.3/4.4 the new bootloader appears
Sorry for my bad english
So as long I stay on 4.2.2 they won't know a thing? I am not in hurry to flash a custom ROM, but I'd rather not deal with this KNOX crap.

As long your not flashing a stock 4.3 and 4.4.2 your fine. If you are still in 4.2.2 feel free to flash custom recovery. Root.custom rom. And if you got any problem feel free to flash a 4.2.2 stock rom. Make sure to backup first. Have a nice day.

Thats what I wanted to know. Thanks. Makes me curious if stock 4.3/4.4.2 would work with old bootloader or if Samsung requires it seeing as custom ROMs seem to work with either of them.
Hey do u wanna trade with me your s4 xD. I'm already with knox 0x0 and 4.4.2

I heard about Knox after I updated to 4.3. I probably won't buy Samsung phones any more.

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.

Ah, yes. This is my understanding as well, I was unclear in my post. I will edit it to reflect this!

Yeah. It would be interesting to find out if you can downgrade the 4.3 bootloader to 4.2.2 after getting root with towelroot, without burning the KNOX e-fuse

[Q] stock rom for N910F via odin no knox flag on

hay' i have note n910f with stock rom but no samsung rom and now i want to change it to stock from samsung.
if i will burn via odin stock rom did my knox flag will change to 0x1?
sorry for my bad english and thank's to the helpars.
Yes, flashing anything via Odin will trip your KNOX flag to 0x1. If that was the question..
@quadlt
Your answer is wrong
Stock Rom means original ROM.
Did you have a original Note 4 with original Rom?
Did you flash anything before?
If you're device is untouched, you can flash ANY original Samsung ROM via Odin without triggering Knox to 0x1

Yip flashing stock ROM with ODIN doesn't trip KNOX
I dream of a root who doesn't trip knox...like the note 3 had....I"m pretty sure it will come soon...

Are you sure? I really Mbolblthlk say yes and others Slatham you know that I will run Knox from personal experience? Just do not feel like losing warranty on a new device, thanks for the help.
Can someone tell me where i can download the stock ROM from for N910F. Many thanks!

rom for SM-N910F
Hi
I just bought note 4 SM-N910F and i came unrooted with vision-x n4 ROM. The problem with rom is that the finger print does not work and there iss no data usage. When i boot(from the first time) on the upper of the screen there is written : Kernel is not seandroid enforcing
set warranty bit: kernel. Searching on the web this shows from the bloatware as there is a custom rom. I used sam moble to find the firmware but dont know which one i am going to download. Searching the APof the cureent firmware it corresponds to the t mobile variant (sammobile.com/firmwares/database/SM-N910T/TMB/) firmware. Can someone help me which i have to choose. Attached there is the the curent CSC.
Did anybody try to flash stock firmware? did it trip knox? I have seen different answers to this question so want to be sure. Another thing is the flash counter that will definitely change and that does void warranty if I'm not mistaken? thanks
Ok, I say this one and for all, I burned stock with Odin and it doesn't trip Knox flag on,it safe.
