Incredibly, there is hope and I now believe it's possible for me to get barge back. I've put an update comment on the post. Basically I've now obtained the required keys and have a 9-min window on 31 Oct in which to request + initiate account recovery!

My tech skills, well, they're kinda all over the place...low-medium level tinsmith :)

Teleconf....like on Discord?

Thanks bro 🙏
