There isn't really a bad HDD, but rather Sony's "oopsie" firmwares that semi-brick systems not using the factory installed HDD. (Its happened like 4 different times.)
Assuming it is an "oopsie" firmware, (which if you updated to most recent, 4.53 would be unexpected,) you need the original unformatted HDD inserted.
Some of the advice from the previous thread on the matter. Hopefully it helps.

If you've already formatted the HDD, a possible step that has supposedly worked for some users to full-format the original HDD as exFAT, and then try installing the firmware again.
Otherwise, the options are installing a hardware flasher to downgrade to 3.55, or sending it to Sony for repairs.
Apologies if this is not the most clearcut guide. There was never really any clear answers released on how to solve this, and I'm mostly trying to piece together as much as I can from what I can find.

this will reset the clock in it as well as any odd settings, then plug it back in, use original sized drive for the model and run from recovery mode, and restore everything to factory and instal the updated again before going through the trouble of ordering a new board
ive repaired a few with this issue, its not easy and its a coin toss on whether your going to git it going right again....sony shaved the monkey to the bone on this one...
