The phone is stuck on the Motorola logo screen, then goes to fastboot mode displaying the message "flashing locked". A stock ROM was attempted, but the device does not accept commands and says that the bootloader is locked. When trying to unlock the bootloader, it asks to enable the option in developer mode, but the phone is in hard brick. ADB and recovery attempts were unsuccessful, and it is also not possible to install a custom recovery. All of this happened after attempting to fix a soft brick issue after an update.
It should also be noted that the device had been rooted some time ago and, when turning it on, it was stuck in a bootloop but eventually booted up normally. The root had been undone well before the device was updated.
