Not having luck… does that mean your wallet still doesn’t connect to a server or that your Trezor isn’t recognized?
Also, what is the operating system you use and do you use a binary version of the FTC Electrum wallet or would you be able to install from GIT?
Sorry for the questions, but I need some more information.
There is no other wallet I know of which supports Trezor and FTC and if you want to continue to use Trezor, what makes sense, you probably need to go forward with the electrum wallet.
if you can install from git, I may have a solution for your actual problem.
I have a working alpha version of the 4.x Electrum-FTC wallet. It is not ready for production, but it has the 4.x fixes of the original Electrum wallet so there is a chance, that Trezor will work.
Unfortunatelly I don’t have a binary yet, so it needs to be installed from git.
