Wintouch Q75S - Removed wpa_supplicant on accident I removed the wpa_supplicant file and now the Wi-Fi doesn't work. Is there anyway to restore this file back? I tried Factory Reset but that only resets the apps and removes user data. The device is running on Android 4.0.4 Ice Cream Sandwich.

Will flashing a new ROM fix this issue?
Thanks in advance.
If you're only missing that one file, you could try using my copy of it:

I'm running 4.1.2, but I'll bet it'll work.
