[i9505] Can't turn on wi-fi
Hello, I just received a used Galaxy S4 and I can't seem to get wi-fi to work. Every time I try to turn it on any other network than my own it simply gets stuck. The only fix that I've tried until now is a factory reset which doesn't really work. The KNOX has already been tripped by the former owner (it's 0x01) and I'm pretty handy with flashing tools like Odin. I've heard about flashing a different "non-HLOS" modem, but I don't really understand which one I should use. I have attached to this post two screenshots of the version, baseband and CSC.
So, what should I do? Should I try a non-HLOS modem? Which one should I use? Is there any way to mess up the EFS that way?
