Hi i jz saw the questions u asked me in the comment of bang dream ~
Here is the steps in order to log in back ur acc via id and pass , hope it helps
By the way , this method only work for once , which means you have to reset your password again after proceeding data transfer in other device
* The password is single-use only and will not function after a Data Transfer has been completed.
If you wish to perform second data transfer, you have to set a new password again for next.
