I tried both but it keeps showing the wrong balance and transaction history of 5 years ago even before I started using the account.
Mycelium has an "
Accounts" tab on the left, check if it has more than one entry aside from your main HD account.
If there are more entries there, its recovery will be based on its type.
If it's under "
Bitcoin HD": You will need to specify the correct derivation path - account_index when restoring it to another wallets like Electrum. (
or use Detect Existing Accounts)
If it's under "
Bitcoin SA": It can't be recovered by your seed phrase, but you should be able to export its private key with "
Export Account Keys" option.
You can then Sweep/Import that to other wallets. (
but do not do it without DYOR first)
But take note that restoring the seed/prvKey to other wallet is just a solution if that send transaction issue is caused by Mycelium's server/client side error or the transaction's structure.
If it has something to do with the actual transaction (
input availability), that wont solve the issue.
