The last year I created three wallets, with Electrum, using Ubuntu installed on a USB. I only saved the files on the USB, Huge mistake
This year I tried to access to the wallets again, but the USB isn't working, so I had to use the seed phrase to recover them.
For two of the wallets, I didn't have any problem using the seed phrases, they worked fine and I can use the wallets again.
But for the last one, when I created it the last year, I used the option available in Electrum to extend the phrase manually, when you install the wallet, so in the next step you have an available space where you can continue extending the 12 word phrase. I extended it with 15 more words written by me, 4 numbers and 8 random keyboard characters like: ')#%&/*@_! .
So in total, the seed phrase was made of 27 words, 4 numbers and 8 symbols. The wallet was succesfully installed, and I made transactions with it. I had written down the seed phrase in a paper, but when I enter it in Electrum right now, using Windows 10 and the last version of Electrum, it doesn't work, no wallet shows up.
Does anyone has any suggestion of a possible solution?
Thanks for your time,
