Hey, i want to upgrade my 9750gii to a 9860, but i am unable to make a backup in fxremote, regardless if im on the "os error" screen or in normal transfer mode.


Edit: should probably mention that the error i get is error 4, thats all i remember, said something about being in transfer mode which i tried, but that didnt work either


Wat do?


Running firmware 02.04.0701.


Btw, the file im gonna use to upgrade the calc is "2_04_0200_sh4.fls", is this the correct one?


Edit: solved, use fxBackup 204 for backing up.

Hello! I also have a fx-9750.

I was dumb enough to not check if my backup for my fx-9750 worked before upgrading.

Now I don't have the fx-9750 os anymore. :(

Could you email me a copy of your backup? My email is tnt84268@gmail.com

I would be very grateful if you could send me a copy.
