Method 1: Unlock or reset memory card password of Nokia phones:
The first hack to recover the password of memory cards will not work on Nokia Nseries and Nokia Eseries devices. Here we will use the remote lock feature for re-setting the password. For this, go to your phones settings >Security >Phone and SIM> and then allow Remote lock. The password of your remote lock will be the password of your memory card. So if you want to change the memory card password, just send an SMS containing your remote lock message.
Method 2 : Recover memory card password, using Fexplorer.

FExplorer software
As I said, we need to download Fexplorer software for this mobile hack. After installation, Browse to c:\system folder in your mobile phone. Here you would find a file mmcstore. This file is actually used to store memory card passwords in a mobile phone. Rename this file to mmcstore.txt and open with notepad. Now you will see the memory card password as it is, exactly. Mobile manufactures are now aware of this trick, and nowadays they use better encryption methods to block access to passwords.

I am Using nokia 2730 Classic.
I recently formated my phone with Restore Factory settings option in Settings of Phone.
After format, My memory card is asking for password which i never used for memory card.
I am very sure that there is no password for memory card but it still asking for it..
I searched many sites and blogs for the solution, I found one with MMCSTORE, but in this case this phone is java based and any file manager do not support access of System folder in C drive(phone memory).
I also tried to search the MMCPWD application but it is also a SIS file, my phone does not support it.
Many people says try formating from phone, but formating in phone also asks for password.
I’ve downloaded FExplorer and installed but when I try to access the system file it shows “Unable to execute file due to security reasons” can you help me on this
