I will reference all the threads I have used to obtain the info from at the end for reference.
So, I was running a pre rooted stock 4.2.2 MH1 without any knox.
Decided to go to 4.4.2 and followed the knox free method for nc5 with mobile odin. It flashed the rom but wouldn't do the bootloader via normal odin, complained that it didnt recognise the device.
So though what the heck, go staight to the latest pre rooted c9 firmware and had a thought. I was still rooted at this point and the phone ran with 4.4.2 nc5 with the mh1 boot loader. I stripped the boot loader out of the downloaded prerooted nc9 rom, flashed that with normal odin, then flashed the whole rom again with bootloader over the top.
I now have official status. No knox flags and root.
In download mode i see the following:
product name: gt-i9505
current binary: samsung official
system status: custom
knox kernal lock: 0x0
knox warranty void: 0x0
csbconfig lsb: 0x30
write protection: enable
emmc burst mode: enabled
Perhaps there is something of significance here for others or maybe someone can point out what I've missed or done wrong.
Thanks for the following threads for their info and inspiration (thanks also given)
