Is it possible to unbrick / recover bricked T5577?

So, yeah, I've been playing with a few T5577 tags, and eventually made some dumb mistakes and bricked them. (Who hasn't made them mistakes though)

To my surprise there was only quite sparse info about debricking T5577 tags, and nothing of what I found, actually helped.

Is there anyone with some experience regarding bringing T5577's back to life? Or have you, bricked some T5577's yourself and came to the conclusion, that it's unrecoverable?

In either case, do tell me in the comments, please!
