Description:
From Android 7.0(Android N), the Android system no longer trusts the user certificate . This may cause the issues such as unable to capture SSL/TLS encrypt packets or no network connection. Therefore, you need to add the LMNx9 Canary root certificate to the system CA directory. This operation is only feasible on rooted device.
Instructions:
1、Obtain an installed LMNx9 Canary's certificate file (.0 format): You can find it under /data/misc/user/0/cacerts-added/ directory (you need to distinguish by file's time attribute if there are more than one file). Or you can export it to SD card in LMNx9 Canary's root certificate settings.
2、Copy the .0 file(do not edit it's name) to the system CA directory: /system/etc/security/cacerts/.
Method 1: Use adb commands to copy，the "<cert>" in the below is .0 file name of yours.
Method 2: Use the applications which can operate on system files to copy it, such as the MT manager.
3、After adding it successfully，you can find the corresponding LMNx9 Canary CA certificate under Settings -> Encryption & credentials -> Trusted credentials -> System.
Notes:
- This operation requires a rooted device.
- No need to configure this for devices below 7.0, the system trusts user certificates by default.
- Updating your system may cause the deletion of the certificate, please check and re-add it when necessary.
