QUESTIONS:

1.
What size of ROM1,ROM2,ROM3 I must save from this old eMMC so that it will work after I replace that old with the new eMMC?
ROM1 is very large. What is the minimal size I must save?


2.
When I replace this old eMMC with new eMMC I must do:


Factory Reset +Format
Repair ExtCsd
Write Rom1, Rom2,Rom3 ( Those I saved previously)

Is that all? Or anything else?


3. RPMB is not possible to save with Easy Jtag PLus? I tried but failed

Thank you.
