I have some btc in a trezor with 1.5.2 firmware. I know my PIN but I don’t have the seed.
I can get to https://wallet.trezor.io/ and see my accounts. However, when I try to transfer btc to my another account I get an error:
Failed to send transaction
Error details: Failed to compile output
I know updating firmware should help, but since I don’t have my seed I’d rather find a way to extract btc before the update.
