Use a “root explorer” (file manager with root support) to copy the file, copy it using a terminal emulator, or push it through ADB (requires the ADB daemon to run in root mode). To do this, the / system partition must be mounted read / write. If your device is rooted, you can avoid this by copying the CA file as the system certificate.
To do this, the device made me install an aspect screen (Pin or password), any other lock screen option is not available and gray with a message “Disabled by administrator, encryption policy or credential storage “ In order to use the university’s WiFi network, I need to install a certificate of authority (WiFi credential). I am using the Samsung Galaxy Note 3 N9005. What happens if I delete the credentials on my phone Here’s how you get to it on my S3, but yours should look similar no matter what phone you have. You should be able to disable lock screen security somewhere in Settings> Security> Screen lock and then change it to none or just a simple swipe to unlock or whatever you want. Just hit the back button and it will automatically go to none. Then a screen will appear saying to change the lock type. Click on that and enter the account details. You will see that “I forgot my password” appears. First change the password lock to the pattern lock. It will then allow you to change the lock code. Then go back into Settings> Security> and Clear credentials. Go to Trusted credentials> User> and delete Foxfi.
Go to Settings and make sure you have removed Foxfi as an administrator. I’ve since uninstalled it and removed the FoxFi certificate, but I still can’t turn off the screen lock (which I don’t really want). To use Wi-Fi tethering, it asked me to accept a certificate and establish a screen lock pattern.
