hey guys, im trying to update my f700bt and i want to back up my current files before doing it. however, when i copy from "my flash disk" and paste into "storage card", it says access is denied. my SD card i am trying to copy to is formatted as fat32. here are some pictures:

Use an empty freshly formatted SD card. Go buy a cheap one that is like 2gb for like 10$. You prob have some files on there that are protecting the drive. I am not fully sure though but that would be my assumption. Or on your SD card you slid the lock tab up if it has one.

can anyone direct me to a tutorial to back up my f900bt?

put testmode 2.3 on a freshly formatted SD card put it in avic and start engine

it will take a moment and then will load to whqat looks like windows 97

click start, choose explorer. click on MY Flash Disk so its highlighted, up top click edit copy

then click on SD card inside your folder so its highlighted, uptop click edit paste
