Some technicians claim that heating the SK Hynix eMMC to 200°C and powering it on while shorting specific pins will clear the RPMB by causing a catastrophic NAND read failure. It is unreliable and destroys the chip.
Every subsequent read or write request to the RPMB partition must be signed using this key. The eMMC controller verifies the signature. If it does not match, the transaction is rejected. 2. Why Do You Need to "Clean" a SK Hynix RPMB?
Locate the hardware schematic or test point pinout diagram for your specific SK Hynix BGA layout. clean rpmb emmc skhynix
When salvaging SK Hynix eMMC from a dead board for use in another device, the old RPMB security keys conflict with the new host’s expectations. A clean RPMB makes the chip behave like a blank one.
The term "cleaning" an RPMB refers to wiping its data and resetting the Authentication Key back to an unprogrammed, clean state. Donor Chip Reuse Some technicians claim that heating the SK Hynix

Place the SK Hynix eMMC chip into the correct socket adapter or connect the ISP wires to your JTAG box. Launch the companion software (e.g., EasyJTAG ToolSuite).
