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 firmware as your device has been flagged as insecure.
3. If the knox warranty line says 0x0 knox will work.
4. with the new knox bootloader root will work, however rooting will trip the knox flag. thanks @
DjeMBeY for correcting this point
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.
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. 4.3 touchwiz leak rom will not work with custom kernels at the moment.
12. 4.3 touchwiz leak rom will not work with the old knox-free bootloader
13. Software affected thanks to @
DjeMBeY
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.
