I have a nexus 5 which is having troubles with wifi (usual 02:: MAC address, no wifi connection) and hotspot.
I tried to change the MAC address with different tools, but it didn't work. I tried as well to put in /persist/wifi some files with the mac address, but still not working.
I've also noticed that inside the /persist folder there are many files and folders missing. I think this may be the reason of the problems.
My question is: how do I restore the missing files?
I tried to search someone sharing that folder(no success), but I understood that I may encounter other problems.
