  • possibility of degrading binary samsung by emmc tool?

    Hello friends. I wanted to know if there is the possibility of degrading the binary version of any Samsung, of course by disassembling the Emmc and programming it again.?


    I also wanted to know if it is possible to expand the internal memory of any EMMC device and what a limitation there would be in that field.

    It's not possible to downgrade bootloader is antirollback protection is enabled.
    However, it's possible that only modem downgrade would work.

        In most phones this is not possible.

          with totally new eMMC chip could it be? or they wear other protection outside of eMMC. I thought that removing the chip and programming one totally nine could.

            ARB fuses are in CPU, not in eMMC. When version antirollback is enabled, in cpu fuse is burned and specific certificate activated.
