I was worried because there is no counter/clean option same like as below

emmc rpmb (replay protected memory block) capacity: 512 kb (000000080000) counter: 25 , response: Not clean

[layder]

If RPMB have counted >0 - it's not clean. It's a elemantary logic

[bhavesh jethva]

I also have issue in samsung j810f emmc was gone and i made backup and write in same name emcp... But phone dosent respond... Rpmb counter was not clean...... But emcp name was same.... So i want to know that emcp will work or not

[amirjco4]

Boss
We wait for new update that can upgrade new emcp and emmc for
Reset RPMB counter
Is it possible or not ?

[layder]

No way to Remove RPMB key now
Counter is consequence and not cause of situation

[hafiz4saqib]

What about this RPMB ?????
If I want replace with new eMMC then it will work ?
Counter 0, Response: Maybe not clean

[layder]

1 bit mode not correctly work to recognize RPMB status

Right now same mobile I dont have to test with 4/8 bit mode.
Could you explain in easy way with yes or no.
If
Counter = 0, status = not clean
Counter = 0, Status = may be not clean
Then mobile would be boot up or no after change the eMMC ???

Now!! I have in my hand Nokia 3 (TA-1032) with Samsung eMMC KMQE10013M.
And its showing that Counter :0, Respose: Not Clean with MLC/SLC life 80-90% consumed.
If I want to rechange emmc with new one then mobile will work properly or no ???
Or both CPU+eMMC changed will be help ....
And other thing is that I cant get eMMC firmware update file from Easy Jtag Menu to clear MLC/SLC life.

you eMMC have use 80-90% of lifetime cells cycles

how you return phisycally lfetime condition to eMMC cells? via new emmc firmware?

how you repair HDD with bad surface? via update HDD firmware or install new Windows?

how you return youthfulness to old people? via new words?

===============
if you want to change eMMC you need use new eMMC with clean RPMB

via 1bit mode we can't get RPMB status

In this case if I do change emmc/cpu then mobile wont turn on properly.
