for recovery, i'd recommend #Electrum, not #Sparrow, though I consider Sparrow in most cases is way superior, but for recovery no.

I have tried both. Blue wallet is the only one that pulled up a wallet with a transaction history at all.
Was following the links sent successful?
Not yet. I loaded a wallet into sparrow. It shows some addresses but no transactions. I am not sure how much time it might need or what else I need to do.
If your Umbrel is on a raspi and you are concerned about overwriting it with a reset, the only “safe” option I would take is buy another raspi and install Umbrel on it and re-establish the seed phrase on the new one. Once set up use the old raspi as backup server.
Other than that I would follow the link darthcoin write up.
I am trying on another hard drive right now. I have to wait for the chain to download and sync before I can see it it works. I am assuming any data that I could need is still on the other hard drive. It seems like the SD card just stores and image for the is and the Harddive holds all the data.
