Default [Q&A][i9505] Knox Q&A / Discussion Thread - ask questions here!

Seeing as the thread in the development section is being flooded with questions when its meant to be a development research thread and important info is getting lost amongst all the questions, I thought Id create a Q&A thread for all Knox bootloader 0x1 related questions so that we can try and keep the development thread just for research and testing.

Please feel free to ask any question here and i'll do my best to answer it but hopefully some of the other members who know a bit more will also join in and help answer some of the questions people have.

What we know so far (I think!)

1. Upgrading to newer Samsung firmware will upgrade the bootloader to knox bootloader. this will give an additional 2 lines in download mode about knox status.

2. If the Knox warranty void line says 0x1 then you cannot use knox softwareas your device has been flagged as insecure. By this i mean that if your workplace / company supports bring your own device to work for corporate emails etc and they use knox to keep security your device will not allow this. You are still able to use future samsung firmware releases with the knox flag 0x1. hope this makes sense. sorry for any confusion this has caused!

3. If the knox warranty line says 0x0 knox will work.

4. with the new knox bootloader root will work, however rooting with CFautorootwill trip the knox flag. thanks @DjeMBeY for correcting this point you can use the root method (Root de la Vega) described here for rooting a device with knox bootloader.

5. If you try to downgrade to earlier firmware / bootloader it will set the knox flag to 0x1 i.e. void.

6. once the knox flag gets set to 0x1 there is no way to set it back (that anyone has found yet anyway!)

7. some newer 4.2.2 software that's supplied with the knox bootloader has been repacked by devs to not use the new bootloader and it all works fine you can still keep up to date.

8. I've seen people trying the test build of 4.3 touchwiz without the new knox bootloader sound and wifi does not work. This is no longer the case, see point 12.

9. There seems to be a big question mark as to weather Samsung will allow hardware repairs under warranty with the knox 0x1 flag

10. only seems to affect GT-i9505 at the moment!

11. Software affected thanks to @DjeMBeY

12. it is now possible to install custom 4.3 TW roms which have been modified to work without the new knox bootloader, do make sure that they are free from knox bootloader before flashing. Do note also that if you already have knox bootloader flashing anything even these 4.3 custom roms will still trip your 0x1 flag

What knox bootloader looks like in download mode . In this picture Knox warranty is in tact as the flag is 0x0:





I hope this answers some questions, anyone feel free to correct me and i'll try to keep this OP updated with info as people supply it / discover it.

good idea,

This thread Must be splitted because of several models that can be concerned in different aspect. ( I9505 or 9500 and others)
this would avoid misunderstanding or wrong rules to be spread over.
Thanks

Its quite obvious that Samsung are not only trying to control the software we use on our device but also how we obtain it.

I dont see many posts about binary counter recently, because now theres a bigger wall that has been put up.

So you cant even check to see if there has been custom software on your device, because doing so would require root which will trigger the knox crap, permanently.

Its that permanently which i have a problem with, and one i believe Samsung will use to reject a warranty claim in future based on that.

They want OTA and Kies naturally. I mean going back to an older official release bootloader via odin break knox? What the hell Samsung.

The saying you cant have your cake and eat it too applies here. I do read some people of the opinion that its my device and i can do anything i want with it, and Samsung you must now fix it when it breaks.


Anything, really? No, and this is the problem, because running custom software gives you the ability to do this. Not because you did, but because you could have and they probably dont have the resources to prove it with every single warranty claim.

So where does that leave the rest of us? In the same boat because they now have a way to prove you did something naughty, theyre not quite sure what it is except knox warranty void 0x1 (maybe).

I just got my new s4 20 mins ago, I've switched it on and it has 4.2.2 MH8 can i use a repacked 4.2.2?

If I cant get root the phone is useless to me as i need to run it in my car with the pioneer appradio arliberator software.
Looking at my Sony it's about that time for SW2 to drop a jam on mine
