Hello, please I need some assistance. In 2016, we used python to generate a Bitcoin private key and then imported the key into the electrum Android app, sent btc there and forgot about it.

I read through the thread and did not see any mention about possible mistake by OP, that Electrum wallet supported Legacy address in the past like 2016 but they disabled Legacy address creation with newest Electrum version.

With newest versions, they only allow to create Segwit addresses if a user does not know deeply technical steps to create Legacy address via command line.

Is this the problem of OP?

Now, for the past one year, I have been trying to recover that address but the private key doesn’t generate the same address anymore. I have used python to generate 5 different legacy addresses but all are different from the very first one.

Like LoyceV said, it is impossible. One private key, one public key and one public address.
