trezor have a new solution for this, didn't check it, I wonder if it will work for the f2a multisig
No, it won't... because the Trezor tool is designed for claiming the BTG from your
Trezor BTC wallet... NOT from other wallets.
If you need to get the BTG from your Electrum 2FA wallet, you'll need to follow the guide that they have provided here... and you'll need BTG Core installed and fully synced... or you'll need to get someone you trust that has BTG Core, give them your Electrum 2FA seed and let them do it on your behalf.
You are right.
I have the core installed and sync finished today.
Need to find the time to do it, I will update here.
Ady.
