So basically if i want to buy new SGS4 now it will most likely have knox :/ I'm "forced" to get HTC One than (no play store in my country so no warranty for Nexus 5 and LG G2 have little dev support compared to htc, samsung) or is there any chance to see production date before buying from imei for example ?
[Galaxy S 4 Q&A, Help & Troubleshooting] malybru:
Hi,

Yes,you are quite likely to have knox if you buy a phone at this point in time.

I have no idea if you tell whether it will have knox ,based on the imei number.

The only thing I can suggest is if you go to a shop and ask to see the settings/about phone page,and see the current firmware on it.

But I cannot see very many shops allowing that.

[Galaxy S 4 Q&A, Help & Troubleshooting] tech_head:
Production date means nothing. They get updated by some carriers while in inventory. The only way to get a specific revision is to buy used. Or buy a developer unit

Hello

I have a android 4.3.

If I root the phone it will increase the Knox counter.

If a later install stock rom again, will I get OTA update even if the Knox counter have been increased (and I have lost my warranty)
[Galaxy S 4 Q&A, Help & Troubleshooting] IberianPrince:
If it's completely stock and system status shows 'Official', then yes, Kies and OTA updates will work again.

Knox and rooting and OTA update

Just to make it clear for a stupid person like me:cool:

S4 with baseband XXUMK8.

1.Okay just to keep it clear. If I root my phone with autoroot (which I have to install CW, since I have to delete a file in order to keep my phone from removing CW), Knox will now read 0x1. If I now download the official and correct 4.3 ROM from Samsung and flash that. Will I then get OTA even if Knox not will work on my device? The 0x1 do not keep my phone from getting updated?
[Galaxy S 4 Q&A, Help & Troubleshooting] IberianPrince:
Yes, you will get OTA & Kies updates again. Just make sure to boot into Stock Recovery after flashing official Stock rom and clear cache with factory data reset... Your device status should be official after that :)

[Galaxy S 4 Q&A, Help & Troubleshooting] the Doctor:
I want to make sure I understand this Knox issue before rooting. I'm presently on 4.2.2. If I root, my status changes to "Custom" and because I have an i9500 I can't use Triangle Away to reset the flash counter and get back to "Official." That being the case, I then can't update to 4.3 via OTA and may even have trouble with Kies, but if I use Odin and flash manually, the Knox bit gets tripped. Is that about right?

Finding a ROM with VOC files

Hi, Im not sure if this is the correct plave to post but....

I managed to flash my Galaxy S4 GT9505 G, with Android 4.3 my Kernal version is I9505XXUEMK9 and the kernal itself is 3.4.0.

I have tried to install a program which requires root access, which i have.

I contacted the developer of the program and he told me I will need a kernel that provides VOC files in the /dev folder of my phone.

I am quite happy to change my rom if I need to (I installed everything with Odin. and Team-win software).

The problem is that I don;t know which kernel version or even the ROM, that i will need to provide these files and get my app working.

Can anyone help?

flah old boat loader on Galaxy S4 i9505

First I should say I read the whole thread and search a lot on net but did find any good answer. I do not want warranty.

I flash my S4 i9505 with official xxuemj5 4.3 rom from SAMmobile.com.

Unfortunately my boat loader is also upgrade to KNOX and I'm not able to downgrade to any 4.2.2 roms or any custom rom.

Even with CWM after flash a custom ROM like "Android_Revolution_HD-SGS4_3.0" I get freeze in Galaxy S4 logo in boot.

I know all of this for new boat loader.

I want to know is there any any to flash OLD boat loader so I can flash with Odin or CWM older rom version like 4.2.2?

KNOX flag doesn't matter I just want my Old OS back.

I recently bought a new Samsung S4 i9505 "European Sim Model" with the German label for the region lock that I have not opened yet.

I think I should expect Knox to be there ..lurking somewhere within the bootloader. I will either send it back, attempt to buy/sell or swap for a second-hand or new-in-box example without Knox. The region lock is less important as I am activating it within the EU but I expect these two features were rolled out at roughly the same time. I really do wish Knox was a feature we could choose to activate, such as encryption.

For when I find a pre-Knox phone, can someone suggest the best method to prevent the OTA update coming through? Be it freezing, deleting, flashing..?

I have the Schrodinger Box staring at me! ...It's tempting to check, but I expect it to be half dead.

Thanks for the reply! I hope that works as I have read that some people have to use Titanium Backup to freeze FWUpgrade.apk etc.

Maybe the use of Titanium Backup is for those with carriers who disable the ability to turn off OTA updates?
[Galaxy S 4 Q&A, Help & Troubleshooting] :
Hi all, noob question regarding Knox.

1. If I have an older firmware without Knox, and I root and flash a custom ROM running the latest Android, I will stay safe from Knox, right?

2. If I update to the latest Samsung firmware, my bootloader will get updated to a Knox-enabled one. When that happens, attempting to downgrade to an older bootloader will trip the Knox flag, right? So I take it that the downgrade will be unsuccessful? I don't understand how Knox can be installed by upgrading but not removed by downgrading. If it comes with the updated bootloader, installing an older bootloader should totally replace whatever comes with the newer one, including Knox, no?
[Galaxy S 4 Q&A, Help & Troubleshooting] tech_head:
1. Correct. LOKI is available on MDK.

2. Will close the LOKI exploit. The new bootloader has the KNOX flag and an excuse that gets burned that prevents the downgrading of older software When a new bootloader is installed it will prevent older bootloaders from booting.
[Galaxy S 4 Q&A, Help & Troubleshooting] malybru:
1.Correct.

Best to keep it that way.

2. a) Yes

b)Yes

c)No

[Galaxy S 4 Q&A, Help & Troubleshooting] :
Thanks a lot. Considering that I am planning on getting the i9506 soon, I'm gonna have to decide if I value warranty more or the freedom of custom ROMs, hah.

Anyway, what other things should I take note to avoid bricks? If I were to say, root using the root de la vega method (knox friendly), enjoy root until I need more thrill, install a custom recovery using Odin (CWM), then use CWM to install a new ROM, will I brick it? I've done extensive research and I don't believe so, but you learn something new everyday. :)
[Galaxy S 4 Q&A, Help & Troubleshooting] malybru:
Hi,

Do not know about root de la vega.

A lot of custom ROMS come with root installed.

So,Odin install recovery,and then,recovery to install custom ROM is fine.

Hi all, and sorry for another, already answered question, about knox. I just want to make sure I understood it right. I am thinking about giving my Note 3 to my wife (Still not sure about this, b/c I like it : )), and taking her i9505. I cannot stand TouchWiz on any Samsung phone except on Notes 2/3.

Now the real question is, if I don't care about losing the waranty, I can proceed as usual, i.e. I flash custom recovery, I flash custom ROM (probably CM), and I have fully functional S4?

I appreciate any help regarding this. Thanks and regards

How to find out the Knox bootloader version?

I cannot tell if my S4 got it via OTA or came with the box..

It was stock 4.2.2 and I installed 2 or 3 OTA updates. When I got to understand this Knox thing, it's already 0X1 so no way back.

Just like to check any way to confirm the Bootloader version?

Thank you very much for the compiled info,

Just like to ask a quick question, so what's the difference between a Knox bootloader and old bootloader to average users?

If not using any Knox software, does it affect anything to Rom bootup process or any other system related matters?
[Galaxy S 4 Q&A, Help & Troubleshooting] Hawke84:
for the average user no difference. only thing it will really do is flag to samsung if you mess about with rooting your phone / installing custom software etc etc. but if you dont care about warranty u can blow knox fuse and doesnt really matter.

only thing you wont ever be able to do is use your phone in a corporate environment if your company uses knox.

Don't root if you too worrying of tripping knox. Samsung made our rooting life very difficulty. I already tripped since 2 month ago and I was free to flash anything I like especially I nearly flashed all the new rom. Warranty is only one year and I already passed five months plus.

On this eml1 bootloader, I can't get the official status. I had to downgraded to emk9 or emke bootloader then I will able to get official status on eml1 firmware. With official status I will able to receive ota upgrade.

Hey guys.

have been away from the Custom Rom scene for quite a while after i lost my 2nd SGSII. Now i come back and read all this crap about Knox. Unfortunately, as I got my S4 just recently, I am already on a 4.3 FW with Knox included. As far as I understood, there is no way of flashing custom roms without tripping Knox. I couldn't care less about Knox itself but I wouldn't want to risk voiding the warranty.

What I really dislike about the stock rom is that it somehow feels laggy. There seems to be a lag of ~0.3-0.5 seconds, e.g. when I am in the browser and press the home button or when i switch the month in the S Planner app.

So ... I am considering going custom ... Has anyone had problems with warranty after tripping Knox?

I know resetting the knox counter from (0x1) to (0x0) in Galaxy Note3 is very hard because it may related to eFuse and if that , then no way to reset it , and if it's Software , then may be someone find away to reset it

that is about Note3 , because Note3 already came with 4.3 bootloader

but about our S4 i9505 , it came with 4.2.2 knox free , so I think it's not related to the i9505's hardware , so it is Software

my first question is : can I reset my i9505 knox counter to (0x0) with someway ?

my second question is : can I downgrade to 4.2.2 ?

I know the knox will refuse the downgrade , but I did read about flashing the South Africa rom 4.2.2 , it passes the knox but the problem will be with the network driver , and it can be fixed with an 4.2.2 network driver

please answer me , and really thank all of you and I will respect all of your opinions whatever happy or sad news , thank you again

Happy Xmas 2013!

Just disable S Voice integration to your Home button. This make your lag feeling, what you wrote above.

I have understood this "knox warranty void" so that when knox-flag have rised, then you just do not have the trust about knox-apps. So I think the "knox warranty void" have just wrong format/ sentence. It could sound like "knox trust lost" etc. I think Samsung cannot therefore void the real warranty for phone itself.

Here some link to todays story about KNOX:

http://www.phonearena.com/news/Samsung-Knox-found-to-have-a-serious-vulnerability_id50670

Samsung Knox found to have a "serious vulnerability"

With the fall of BlackBerry, companies are scrambling to pick up the enterprise market share that is up for grabs. Samsung desperately wants to make a dent in that space, but a new "serious vulnerability" found in Samsung's Knox security software could make that quite a bit more difficult. Cybersecurity researchers at Israel's Ben-Gurion University of the Negev found the security flaw.

The vulnerability reportedly will allow malicious attackers to track emails and record data communications. The researchers say that the worst case scenario for the flaw is that it would allow a malicious attacker to "easily intercept" secure data, modify data, and even insert hostile code which could put a secure network at risk. The vulnerability was found earlier this month, and Samsung says that it has investigated, but claims that the flaw isn't as serious as the researchers make it out to be. Samsung says that the testing was done on a device without the full corporate client software package installed.

The news of this flaw comes at a bad time for Samsung, as the U.S. Department of Defense has just purchased about 500 Samsung Galaxy S4 smartphones to test. If the devices are deemed to be secure, they would be used in the Pentagon. Of course, a government spokesman was clear to say that no devices would be used if they weren't found to be secure.
[Galaxy S 4 Q&A, Help & Troubleshooting] GlossGhost:
Merry Christmas!

That's a nice idea and maybe it is like that. The thing that leads me to this is that half of the service support calls confirm that knox flag voids your warranty, otgers say that it doesn't. Maybe there's no information from Samsung about knox at all.

hey everybody,

got a new sgs4 today, came with 4.2.2, installed twrp and rooted it, then i was going to install a custom rom,

probably newest omega rom v18 XXUEML1

but then i have read about this knox bootloader, which is all a bit confusing... or maybe only for noobs :)

now i got 4 questions:

can i install a newer (4.3/4.4.2) custom rom without updating the bootloader?

does this knox bootloader only affect samsung based roms or also cyanogenmod based ones?

does it matter if i install a custom rom + custom kernel in custom recovery or odin in terms of knox flag?

what happens when the knox flag is set to 1 except void warranty? stuck in bootloop? root remove/block? or anyything else?

Thanks.....So currently KNOX free.........

In terms of flashing ROMs in recovery, if you follow the install intructions for whichever ROM you choose (4.3/4.4) you should be OK and no KNOX related bootloader should be installed on the phone. Afaik you can only get the KNOX bootloader via flashing firmware/bootloader via ODIN and not in recovery. I may be wrong:eek:

I am very familiar with Omega ROM :silly: and as long as you follow the instructions in the OP for the old bootloader you should be fine.

It will be well worth your while doing alot of reading through the various ROMs that are available and then making a decision.
