BestMemory - Highlander series - 480GB (SM2258XT)

Hello, i have this SSD, 480GB in safe mode, reporting 1GB in MRT.
PCB has 2 NAND chips, and PCB number is "SM2258XT_......_R0724"
Choosing SandiskPlus family - SM2258XT i get this:

Code:

Selected family : ............................: SanDisk SSD SM2258XT
Master Controller model : ....................: SM2258XT
Chip id : ....................................: 0x453C98B37672
Vendor : .....................................: Sandisk

SSD state:
Wether it is in a ready state : ..............: Yes
Firmware working mode : ......................: ROM
SSD error code : .............................: 0x00(No error)
Whether SSD is locked  : .....................: No
Whether in safe mode : .......................: Yes
Whether access user area : ...................: No
Whether access SA  : .........................: No

Load loader...
Default Loader name : ........................: S1022A0 BiCS3_02
Write default Loader : .......................: success
Load default Loader code : ...................: success
Obtain Loader version from firmware : ........:

After that asks to load loader manually, choosing "S1022A0 BiCS3_02" gives me better result, but....

Code:

Read Loader : ................................: success
Loader name : ................................: S1022A0 BiCS3_02
Write to Loader : ............................: success
Execute Loader code : ........................: success

SSD state:
Wether it is in a ready state : ..............: Yes
Firmware working mode : ......................: LDR
SSD error code : .............................: 0x00(No error)
Whether SSD is locked  : .....................: No
Whether in safe mode : .......................: No
Whether access user area : ...................: No
Whether access SA  : .........................: Yes
Load loader : ................................: success

Basic SSD information:
Read chip information : ......................: success
Chip id : ....................................: 0x453C98B37672
Vendor : .....................................: Sandisk
Flash type : .................................: 64L BiCS3 QLC 16k
Chip capacity : ..............................: 8192 Mb
channel number : .............................: 1
Chip number per channel : ....................: 4
Chip layers : ................................: 2
Number of logical units : ....................: 1
Number of chip storage blocks : ..............: 0x1000
Number of pages per storage block : ..........: 0x100
Page size : ..................................: 0x2000
Maximum retry level : ........................: 0x0

Load relocation block table : ................: Fail

Code:

Load CP list......
CP list data is not found in HDD, use the default CP list!


Load CP list... : ............................: success

Read password information...
Read password information : ..................: Fail

Of course it fails trying to "create virtual translator"

Tried some other loaders, including "R0724A0...."(because of PCB number) but they all fail in "Write to loader" and "Load loader".
Downloaded a few "SM2258XT......BiCS3......" over the internet but all "MPISP2258.bin" fail to "write to loader".
Does it matter when MRT chooses first to load "S1022A0 BiCS3_02" by default after selecting family, and before choosing the loader manually?
Thanks

You can rely on what the program automatically selects, but in these controllers, LDR selection often has to be performed manually with the appropriate configuration/memory type:

Thank you Lukas,
do you have any hints for what i should look for?
Nand is 45 3C 98 B3 76 72
64L BiCS3 QLC 16k
Do you edit the MPISP2258.bin file?
