When installed Cardblock.A appears be a cracked version of InstallSis providing user with ability to repack already installed SIS files and copy them to another device.

However when user tries to use Cardblock.A to copy an application a payload triggers that blocks the MMC memory card of the phone and deletes critical system and mail directories.

Blocking the memory card is done by setting a random password to the card. So that after the phone has been once rebooted, the card is no longer accessible on the phone or any other device, without entering password. And as the password is a random code, that is not provided to user, the card and it's contents are unusable until unlocked.

Deleting system directories destroys information about installed applications, users MMS and SMS messages, phone numbers stored on the phone and other critical system data.

Phones using Symbian OS 7.0s or older, such as Nokia 6670 and 6600, can recover from deleted system directories at the next boot.

However phones using Symbian OS 8.1a, such as Nokia 6630, cannot recover the system directories, and thus fail to boot properly and show message that instructs to take the phone into maintenance. Such phones can be recovered with hard format operation described in disinfection instructions.

If you have installed Cardblock.A and triggered the payload, do not reboot the phone before using sync software to make backup of the card contents.

As long as the phone has not been rebooted after the Cardblock.A infection, the MMC contents are still accessible and can be copied to PC.

Use PC sync software to copy the card contents to PC and from there to another card.
