[SOLVED] WIFI not working after replacing /editing /modifying the wpa_supplicant.conf file

How to solve WIFI not working if WPA_supplicant.conf is modified or changed.

I ran into the problem one day when I was just playing around my Android phone's wpa_supplicant.conf file.
I happily rooted my phone and went to /data/misc/wifi folder and edited the file using root explorer and saved it. Till this point it was all looking so easy. I rebooted my phone and was surprised.
My Wifi was not switching On at all after replacing the wpa_supplicant.conf file.
Tried many things but did not solve the issue. Was thinking to factory reset my phone.
Somehow I found the solution to WIFI not working.

The reason was, when we edit the wpa_supplicant.conf file while saving the ownership to file changes as we will be editing the file as a root.

You can see from the screenshot, the ownername and ownergroup are changed to "root" instead they should be "wifi"

The solution to wifi not working is,
$ adb root
$ adb -d shell

# cd /data/misc/wifi
# chown system.wifi wpa_supplicant.conf
# reboot

Hope you find this useful.
