RPMB - questions

[gautamgzb2]

Today i want to repair an emcp of Asus zenfone max M2 (XO1BDA)
I remove emcp and check in easy jtag plus then the emcp health status is very bad , so according to the solution the repair process is backup rom2/3 and security partition, i did it well
I can't take backup RPMB partition because when i try to read emcp in easy jtag classic suite the tool stopped working
I universal factory emcp and erase all rom after erase emcp and create gp partition emcp health staus is normal now.
So write back ROM 2 , ROM 3 firmware and security backup as well and there is no backup of RPMB partition so emcp will work or not.
I solder again emcp to pcb but phone can't boot up it show only Qualcomm port 9008.
Is RPMB partition is important for boot up or not if yes so now how to write previous or new rpmb partition even i have no file for them.

This is section only for RPMB.
But according your description there is need more detail about 2 things.
1:- Health Report (Before GPT Partition)
Share your Log on new post.
2:- RPMB Program detail (counter etc)

Hello masters ,
I need a quick tip from y’all about RPMB , Foe understanding this better please have a look on below example.
I know some phone boots normally irrespective of the RPMB status but most of them do creates issue so please have a look on my Little post.
Suppose I have a phone ‘X’ with its original emmc ‘1’ and it has no juice left , and on reading info if it’s says RPMB Status is not clean then can I change it’s replace it’s emmc from Phone ‘Y’ with emmc ‘2’ who’s RPMB status is clean OR the emmc ‘1’ from phone ‘X’ should also have Clean RPMB status 0R Emmc of phone ‘X’ should be clean and the emmc ‘2’ from the Phone ‘Y’ can also be not clean or clean .
Please Masters it’s my humble request to clarify my little doubt .
Thank you .

At most ccases you need use eMMC with clear RPMB, if eMMC at device uses RPMB (not clead)
If you device have RPMB clean, you can yse any eMMC to replace
And sometime devices wirh ysed RPMB can work witk used (not Clean) RPMB
