Restoring SMS messages using mmssms.db file

My Nexus 5x phone died from the “bootloop” syndrome.  I had unlocked bootloader on it and TWRP recovery image was installed, so I was trying hard to get at least some data off the phone.  Most of the time it would not boot at all, but I managed to boot into TWRP recovery after leaving the phone in the freezer for a few hours.
