Not sure if I accidentally double spent my LTC LITECOIN
The underlying problem is that somehow Ledger did not broadcast my transaction to the mempool. Don't know exactly why it wasnt relayed.

Solved in the following way:


Close the LTC Chrome app
Download the LTC-Version of Electrum Wallet. This wallet interfaces with the Ledger directly, like the chrome apps. No need to import the seed.
If Electrum gives a read error make sure you enable and disable broswer support once.
Make sure you started the correct app in Ledger. In my case it was LTC.
In Electrum go under the tab "Addresses" and copy one of your receiving addresses with 0 balance
Send YOUR ENTIRE BALANCE at once to your own copied address. For good luck make sure the fees are sufficient.
Wait until it confirms.
Thats it! When you start the chrome app again the new transaction will have replaced the unbroadcasted old one and the balance returns to the correct amount.


It should work in principle with every currency.
