After importing my xprv master key in electrum, how do i get correct balance in ...

I have created a wallet in electrum. I used option standard wallet/I have a master key. I have entered my xprv which I got from a dump of my wallet in bitcoin core. I expected to see 4 transactions from 2022 and 1 from 2025 and a positive balance. Instead I see 0 balance and 0 transactions. What should I do to see my 5 transactions and to be able to send out some BTC? I have also created a watch only wallet in electrum where I have imported my adresses from the same bitcoin core dump. In this wallet I see the 5 transactions and the positive balance.

The issue is your derivation path. Electrum uses different paths than Bitcoin Core.

Go to Wallet → Information in Electrum. Check the "Master Key" and "Derivation" fields.

Your Bitcoin Core xprv likely uses m/0'/0' for receiving addresses. You need to create a new wallet in Electrum using "Use a master key" again, but this time enable the option "Enable multi-signature" and set it to 1 of 1. This will let you manually set the derivation path.

Enter your xprv and set the derivation path to: m/0'/0' for the first keystore. This should make your transactions and balance appear.
