Hi there,

I have some BTC stuck in an Electrum multi-sig that I setup a couple of years ago.

The wallet is set up as a 2/3 multi-sig wallet, with #1 being Electrum, #2 being Trezor One, and #3 being Ledger Nano S.

When I try to sign a transaction with Electrum (and then sign + broadcast with Ledger Nano S), it won't work because Electrum won't detect the Ledger Nano S.

When I try to sign a transaction with Electrum (and then sign + broadcast with Trezor One), it won't work because of the error "DataError: Expected input with amount".

I am on Mac and using Electrum 3.3.8.

(I tried updating to the most recent Electrum version, and it didn't work either. I think that's because according to the release notes, after 3.3.8 something changed with the Electrum partial transaction format - which I'm guessing applies to multi-sig transactions).

^ Release notes (see under Release 4.0.1 - (July 3, 2020): https://github.com/spesmilo/electrum/blob/master/RELEASE-NOTES

Please let me know if there's any other information I could provide to fix this. I would be forever grateful to whoever can help.

Also, as mentioned, I'm willing to pay $1k of BTC to whoever can help me fix this issue

Thank you!
