I only see here next: if you have working console over exlink (but I doubt about that...), you could flash firmware and hash partitions by hand. I could help you, but need some info from your tv.
Make exlink (for B series -look at the wiki) and gain shell access. Then I write what to do next.
or find PC with com port. It is up to you. Even you can leave TV as is, unchanged.
Thanx a lot
