[HOW TO] Backup WIFI networks without Titanium Backup (Requires Root)
I'm sure this is mentioned somewhere else but haven't found it in the S4 forums...I was annoyed that Titanium Backup kept failing to backup my WIFI passwords...so I played around with the files and found it quite easy to back them up myself...as long as you have root access
NOTE: Be careful whenever moving/editing/renaming anything in your ROOT directory. You can cause serious issues, including bricking your device, by making mistakes here. Be especially careful if you are on firmware MF3, with no stock image/recovery, as fixing these mistakes is significantly more difficult, if possible at all.
- Anyways, use a file explorer with root support (on your rooted device...I use ES File Explorer but others are great too) and navigate to the following folder (from root): data/misc/wifi
- In that folder, you will find this file: wpa_supplicant.conf
- Copy that file to your MicroSD or wherever you prefer to have it.
- Now, when you want to restore those passwords, simply copy that file to the same directory and overwrite the current file.
- You can also open that file in windows with notepad and, while not visually pleasing, view the passwords in the text.
I hope this helps someone! I wish TiBu would fix this already...S4 is kind of popular so not sure what the hold up is. I am pretty sure there are other backup programs that having a working WIFI backup...but I didn't want to install something alongside TiBu just to do this simple functionality.
