I bought a S4 I9505 because my I9001 is lost (and microSD and replaceable accu is important for me).
I know that Samsung has integrated KNOX since 4.3 to the devices. The flag changes from 0x0 to 0x1 while flashing.
The most of the threads and articles are dated from 10/2013 to 01/2014. While that period there was no chance to reverse the flag.
Now, it's middle may. Does the status of progress change somehow? I read about eFuse. Note3, Note 10.1 2014 and S5 have that by default, because they were run 4.3 and above since release. The S4 had 4.2.2 on release (when I started my device 4.2.2 was installed) and KNOX was enabled by software after update to 4.4.2.
So the question: Has the S4 the eFuse too?
I had nothing done yet but it would be helpful to know.
