I put tails on another usb and transferred my persistence folder over. Then I opened electrum and entered in my seed but it gave me some weird wallet with no receiving addresses and some transactions of 200+ btc. Is there a file I can copy over from the old usb to the new one to get my wallet back?
Try restoring from your seed words.
You can access your current wallet file from the file manager like this:
Places > Home Folder
View > Show Hidden Files
Double click on ".electrum"
Double click on "wallets"
Right click on "default_wallet" (or other wallets if you have them) and select copy.
Select where you want to save it and do a right click save.
Also check this:
Start Electrum.
Do Tools > Network
Make sure that you have the following settings:
You may need to shut down Electrum and start it back up to get it to connect with the new settings.
