Hi,

Same FW version required.
Otherwise U have to swap ROM provided that the board layout (CPU, motor controller...)is the same.

i switched the segate rom but hdd dosent spin up

if hdd does not spin up it does not have anything to do with ROM , check motor for damage.

try cleaning the pins on the connector block and bend the tabs up so they make better contact see if it will spin again. Either that or your donor was no good, or you missed something when you soldered the chip.
