Hello guys hows your new year?
i received this drive that doesnt spin at all and stay BSY with error LED:0x000000BD FAddr:0x000059D8

iv tried the official guide https://blog.acelab.eu.com/how-to-fix-a ... -chip.html

but with donor PCB "after Repeat the unlocking steps (1-6) " i cannot enter the command OI1 ..... i will get LED:0x000000BD FAddr:0x000059D8 !AGAIN
and if i skip this command and Repeat the unlocking steps (7-9). the drive spinds but i get Waiting drive spin up ! therefore i cannot use the terminal !
with original PCB is the same.....the drive spins if i change to 82 34 56 78 but i cant enter the command OI1
i also noticed that nomatter how many times i write the patient rom into DONOR PCB it will show the SN of the DONOR.........
any help will be very very helpfull

i also noticed that nomatter how many times i write the patient rom into DONOR PCB it will show the SN of the DONOR.........

try ROm Programmer to write Patient ROM or change Terminal Speed,

Good Luck...

programmer ? Sir this drive has no tsop rom on it! the rom is stored inside the nand flash!
anyway when i disconnect the pcb from the patient drive it gives me the patient SN but when i connect to the patiend hdd it shows the donor drive SN

it has NOR flash (serial flash) albeit not TSOP indeed, but BGA. It is the ~3x2mm chip near the DRAM.
ROM is also present in NAND and some parts of it are read from there normally.

yes right Sir . you 100%...unfortunatelly im stuck.................... maybe non compatible BGA on the donor? but the drive spins when i set 82 34 56 78
however BSY and same terminal error

can somebody tell me which is the correct position for the read channell? i tried many times but is still get the error LED:0x000000BD FAddr:0x00008004

should i short before or after the tech Unlock Handshake"?
should i keep the position untill the drive get ready ? if the position is correct will the drive keep spinning or will stop spins?
