in the .80 thread, some one said that you could crossflash the firmware with the TS-H352c
QUOTE
The easiest way to crossflash the drive with the no check option is to open a command prompt and change to the directory where your sfdnwin.exe file is and type in "sfdnwin.exe -nocheck" and hit enter. You should get a message box that pops up that says "-Nocheck Use!!" and you'll have to hit ok to continue.
Could I do this with the TS-H352. If so would it be the same way with .81
