After entering the link, the Certificate Installation window pops up, follow the instructions below in option 2, Step 5.


2. If "Can not install because the certificate file was not found" or "Can not find app to open application":

  1. Download the certificate (when connected to NetFree) from here http://netfree.link/netfree-ca.crt via the device's browser, or download the file to a computer [1] and copy to the device (in case there is no browser app on the device).
  2. Open the Settings app אייקון אפליקציית הגדרות on your device.
  3. In the Settings menu click on Security & location > Credential storage / Advanced > Encryption and login information > Install from storage/Install from sd card (please note! The exact settings name varies from device to device, so you can use the search box)
  4. Go to the folder where the downloaded certificate is located from Step 1 > Click on the downloaded file (default certificate name is netfree-ca.crt).
  5. In the panel that opens, give a name to confirm (any possible name) and choose the option VPN and apps
  6. Click on "OK".
  7. If you have not already set up an access code, pattern, or password on your device, you'll be prompted to do so.
  8. Repeat these steps and in step 5 select Wi-Fi.

For Android 7.0 and higher

By default, apps do not reliy on certificates added by the user only of system certificates, so most apps that will not work even after installing the certificate as above.

Solution:

If you have Root authorization, see here or here

Copy the cetificate (In Android-optimized format - download from here) to the system certificate folder path system/etc/security/cacerts/ thus causing the certificate to be a system certificate. This can be done easily using the appRoot Certificate Manager, download from here.

If TWRP Recovery is installed:

You can copy the certificate to a system certificate folder without rooting. You can read the tutorial here.

Installation using magisk module:

You can copy the certificate to a system certificate folder without rooting. You can read the tutorial here.

If you do not have Root authorization:

There is a partial solution for each app individually, see here.

There is currently no perfect solution for Android 7 and above without the need for root permissions or custom recovery installation.


Problems and solutions

In different versions of Android sometimes at the point of installing the security certificate, a message pops up asking for "Enter the password for credential storage".

Try entering the device PIN code. If the PIN code is not accepted or the PIN code has not been set, follow these steps:

Go to > Security & location (or Security) > "Clear credentials".

Then go to Settings > Screen Lock (sometimes, lock screen settings appear on different devices in other places, If they are not in the general settings, try searching under Security or Display). Set a pattern lock (It may appear as line). When setting up the pattern, you will be asked to set a PIN code for recovery, set a PIN code it is important to remember it.

Restart the device.

When the device has finished restarting, you will be asked to insert the pattern to open the device, enter a wrong pattern 5 times and then enter using the recovery PIN you set up in Step 2 (click "Forgot pattern").

after you signing in to the device, go to Settings > More Networks > VPN, a window will pop up that will require a PIN code, enter a different PIN code than previously defined.

Now you can install the security certificate.

Please note: There are also malfunctions in devices lower than version 7.0 that can be created and, if necessary, consult a specialist technician.
  1. Make sure that the computer is connected to the same NetFree ISP to which you want to connect the device.
