Change WiFi credentials

If you wanto to change WiFi ssid and password without using the Yi app, you can do it with an SD card. This method only applies if your cam has already been hacked.

1. Remove power from the cam.
2. Download the following archive and decompress it to a FAT32 formatted SD card: sdwifi.tar.gz
3. Edit the file configure_wifi.cfg according to your needs. Pay attention to the special chars:
   • Use only the following special chars: \ | ! " $ % & / ( ) ' ? ^ [ ] @ < > , ; . : - _
   • Don't use double quote " around ssid and psk
   • Space chars are allowed
4. When you open the SD card you must have the yi-hack folder with 3 files inside.

/ --- yi-hack --- configure_wifi.cfg
              |-- configure_wifi.sh
              |-- startup.sh

5. Insert the SD into the cam and power on it.
6. The cam will reboot once.
7. Check the wifi connection.
8. Remove the SD card or delete the files listed above.
9. The script makes a backup of the flash partition where are stored ssid and password (in case something goes wrong).
