Sympathies/condolences. I did this to myself back when I was into Nano and reset a phone to troubleshoot it while being 100% sure I'd written down the phrase correctly. That's 30 shitcoins I'll never see again, and I have a constant fear I'll repeat that with my current BTC collection. Really hope that correct mnemonic turns up.

(As an aside, I think about the number of times I've lost physical keys to places, and man does the concept holding my own keys not quite give me the confidence it should.)
