BTC stuck in Electrum multi-sig (will pay $1k reward)

o_e_l_e_o he also has to select legacy p2sh as the script type.

o_e_l_e_o he also has to select legacy p2sh as the script type.

I'm not sure he does. If he enters his Electum seed phrase as the first signer, then Electrum will automatically choose the matching script type for the two hardware wallets and he won't get a choice. He'll only get shown a choice if he enters one of the hardware wallets as the first cosigner, but if he picks the wrong script type then Electrum will return an error when he tries to enter his Electrum seed phrase and he won't be able to generate a wallet at all.

CMIIW though.

Hi all,

Thanks for all your help, but I was able to figure it out.

Here's what I did in case anyone has the same problem:

1. Used someone's Windows computer
2. Loaded up Electrum on there - same version 3.3.8 - with Electrum + Ledger wallet files
3. Ran Electrum as administrator (may or may not have helped)
4. Signed transactions from Electrum wallet file
5. Before signing + broadcasting with Ledger (via Electrum), I did this:

You need to modify the ledger.py file found in x:\Program Files (x86)\Electrum-RVN\electrum\plugins\ledger.
You can use notepad to modify it. Under DEVICE_IDS = [ you should see something like (0x2c97, 0x0001), # Nano-S
You need to change it to (0x2c97, 0x1015), # Nano-S
Here are the codes for the different Ledger
Ledger Nano S : Product ID 0x1015
Ledger Blue : Product ID 0x0015
Ledger Nano X : Product ID 0x4015
Hope this helps

Personally I changed the DEVICE_ID to (0x2c97, 0x1011) after (0x2c97, 0x1015) didn't work because:

You can find your product ID in Windows device manager in the details tab of your Nano. It looks like USB\VID_2C97&PID_1011

6. After making the above change to the ledger.py file in the Electrum program files, Electrum detected the Ledger, and I was able to sign transactions and broadcast them!

7. I had to wait a bit for the transactions to sign + confirm (I think because I had a lot of inputs), but damn it finally worked

Again, thanks to everyone for their help. And I hope no one has to go through this

What I thought would be a nice HODL ended up being very stressful.

I think the lesson is to not overcomplicate things if you aren't a pro

Very nice kung-fu! Congratulations!

Glad it worked out for you.  

Technical issues like that is what puts me off using hardware wallets, which is why I like to keep it simple and sign via electrum air gapped computer.

A multisig with 2 different hardware wallets isn't the most standard way to use hardware wallets, so I don't think this should be a reason not to use them. I would however recommend funding and withdrawing a small amount before putting your life savings into a multisig address. It also doesn't hurt to verify you can do the same from your (seed word) backups.
