I set up two factor authentication on a Blockchain.info wallet with an Android device that had its firmware fail. I had to reinstall the firmware for my phone, and now the authentication no longer works. Was the authentication associated with the IMEI of the device, the SIM, or the ROM? I have lost the ROM and I did not back up the settings or configuration partition for my device.
I still have access to the email and IP Address that was used to create the account. I don't remember setting up a recovery phrase. Does anybody know how I can recover this wallet?
if you have the mnemonic phrase you can recover the password for it and maybe change it and if you don't then there isn't much luck on your side because blockchain support won't help either, another thing you can do to get your account back is get someone to crack it and pay them the fee
