New Blockchain.info wallet but where are my bitcoins? How to access them?
This method will only work if you didn't imported any addresses to your account. (Reason? "Please note that imported addresses are not backed up by the wallet recovery phrase. We strongly recommend you sweep funds from imported addresses." Source)

First go to Electrum and download the wallet from there.

Then install &amp; open that wallet.

While opening, select "standard wallet"

Then select "I have a seed"

After that you will get a screen like this where you need to import your 12 word seed:



Then click on "options"



After that click on "BIP39 Seed"



Then the wallet will have your BTC with the same address.

Hope this helps you in some way.
