Thanks for the reply. Is there no way i could get the key back?
Its like this:
If you are completely sure you wipe the drive, you can get the key by:
- JF Key DB
- Keyvault (this requires JTAG or at least CPU key)
Other than that, no you just bricked the console. Try searching for JF logs, or maybe sabed OFW/CFW somewhere in your computer.
The new firmware update is applied by sectors, so restoring is impossible through this metod.
