[Ethereum] How does a Jaxx backup phrase work

You should be able to restore and recover your wallet by following this Jaxx Knowledge base solution:

Then just rename the "C:\Users\\AppData\Roaming\Jaxx" folder to something else, make a new "C:\Users\\AppData\Roaming\Jaxx\Local Storage" folder, copy and paste file__0.localstorage into "C:\Users\\AppData\Roaming\Jaxx\Local Storage" folder. Next the install the latest version of Jaxx Desktop and run it to let it onboard/initialize the wallet, you will need to initialize each coin wallet using the "<" or ">" and clicking on the coin name. Then Go to options->tools->backup wallet->View Backup Phrase and write down your wallet backup phrase and put it in a safe place, really this time.

I retested it on

using "Mnemonic phrase". Here you can choose a different address path and it says which one is used by what type of device.

It turns out Ledgers use m/44'/60'/0' instead of m/44'/60'/0'0/0, so my phrase was correct. It seems that currently the Coleman BIP39 tool doesn't support m/44'/60'/0' paths.
