After hundreds of trials of flashing&modifcation. I found it is not true for upgrade buslink 48x12x50(aopen oem with justlink tech) to 52x24x52.
After failure of using aopen firewire 52x24x52 v.1.50.
I reflashed the drive with the aopen v1.40 one which this website provided
aopen oem firmware1.40.
I also found there're some bugs in the file.After flashing, My system become unstable and got crash everytime I run the Neoinfotool and drivespeed program.
Can anyone noticed about this!!! Or that's only problem happen to me??
Anyway, The hack for modify the buslink48x12x50(justlink)to 52x24x52 is not true.
But I'm not true about the Liteon one.
Anybody has comments on this??
