Who does the recovery?
I do, personally. Every job is manual — it isn't automated with a tool and it isn't resold to anyone else.
Do I have to own the equipment?
Yes. I only help owners and authorized maintainers regain access to their own projects — in line with the authorized-use-only policy on the channel.
Do you sell a tool or a download for this?
No. There are no tools for sale and no downloads on this site. Recovery is a manual service I perform or guide you through.
