If your Ledger Nano has been lost or stolen, your funds can still be accessed by importing the recovery seed into Mycelium for Android.
A fresh install of Mycelium is required. If you already have Mycelium installed, backup your wallet and reinstall the application.
When opening Mycelium, you’ll be given two options: Restore Backup and Create New. Select Restore Backup.
All Ledger seeds are 24 words, so select 24 words:
Mycelium will have you enter the words one at a time.
You can now send any funds that were stored on your Ledger Nano.
Note that the private keys from your Ledger Nano seed are now stored in Mycelium. Your funds should immediately be moved to cold storage. The old Ledger Nano seed is now insecure and should not be reused.
