It applies to ABB Compact Control Builder (CCB / CBM) software, AC 800M controllers (PM851, PM860, PM861, PM864, PM865, PM866, PM891), System 800xA engineering libraries, Standard, custom, and user library (.afw / .mdd / .lib) files.

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.
