Help restoring 9750GII to origional state
I have a 9750GII that I upgraded to the 9860 OS but now I want to restore it back to the original OS.
I have a backup of the original OS however when I try to put it on the calculator I get errors from the pfxrecover program as the OS doesn't match.
The current OS I have is 2.01.0200, the original I believe was 2.00.0700.
Thanks if anyone could help that would be great.
