Same thing happened to me also
I just want to relock my bootloader so I just trying to do stock noughat flash, after noughat flashing I did and side load of Oreo opj28.111-12 . After successful completion, the phone should be reboot. But it bricked and only the led indicated blinking. I tried all older blank flash . Still dead . Blinking led is like last oxygen of my moto g4 plus :crying::crying:
