Hi, try to downgrade the firmware to the Android 5.0.2 version of the older security patch level. Since you have the firmware installed the Android phone 5.0.2 with security patch level of December, try to degrade the patch level you security Making the flash of another firmware with security patches before October 2015 did this, try rewriting the certificate in the phone and see if it writes it correctly
