no,i have lost the backup
however,thanks a lot bro.
Try your best to enter correct password if not you will need 12 word recovery phrase like bl4nkcode have said above.
Blockchain.info doesn't save any of your wallet info in their database other than your wallet identifier and encrypted wallet file so their support can't help you to recover your password.
Thank you for your kind information.
I have forgot my bolckchain wallet password. now what i will do? how to recover this wallet??
Here you have three options to recover your wallet .
1) Try every possible password that you used in the history , Probably you can access ( specially I recover my account through this trick in one week )
this one is best idea to me.thanks a lot every one, i am going to lock this thread.
