If it was permanently bricked, then no. The device would be in a state that it could not restart the flash process.

If reflashing were possible with the original ROM, it would not be considered permanently bricked.

It would be possible that an OEM or advanced specialist may have the ability to salvage a permanently bricked device, through special equipment, and/or repair/replace components. However for all practical purposes, if a (update/patch/hacking) process can leave a device "permanently bricked", an end-user cannot recover from that state.
