Does anyone know how to unlock MMC cards protected with password and when the password is not known and can not be extracted from the device that locked it ?
Something like This can unlock the card but the data will be lost.
They use standard MMC-command to unlock cards with the whole data erasing like Security Erase on HDD
If you need data - unsolder chip, read it on programmator and decode translator schema to get correct data or unsolder, find the password and reset it then solder it back
