MediaTek phones do not accept changing the memory unless the name of the memory to be installed is registered in the perloader file
In case the memory is EMMC, we can find out which memories are compatible with the phone through the perloader file, through the interface of the box, whether it is easy jtag, medusa, ufi or cm2
But if the memory is UFS, there is no box that is able to know the names of the memories recorded inside the perloader file
To solve this problem, we open the perloader file using one of the hex programs and you will see the names of the memories compatible with the phone
Note that the LUN0 file contains the perloader file inside
The file LUN1 contains a file perloader 2 .
For EMMC from SAMSUNG, we can change cid for it to make it compatible with the phone
As for UFS memories, they do not support this process. To solve this problem, we can write the name of our memory inside the perloader file using the hex program and here the phone will work normally
But this method is considered immoral because the perloader file has become modified and as soon as the phone flashes an official flash the phone will die because the name of the memory is not registered in the official perloader file
NB
The same method can be used with non-Samsung EMMC memory by writing the name of the memory inside the perloader file
As you know, Easy Jtag Box does not support writing scatter flashes for phones that have a MediaTek processor and UFS memory
If you have a dead phone, you can write the perloader file to LUN0 and perloader 2 to LUN1
I mean, you write the file as if it was a dump file
