An eMMC chip from a salvaged Samsung phone, for example, will have a programmed RPMB key. To use that chip in another model, the RPMB must be cleared so a new key can be written. clean rpmb emmc skhynix

The is a dedicated, secure partition found in SK Hynix eMMC and UFS storage chips designed to protect sensitive data against replay attacks.
