By installing it took a while!
I'll write to you because I'm not a PC Spezi my steps!
1. An external hard drive to FAT32 formatting with PC / Laptop.
2. In the USB slot Playsie and update from the network directly to the external hard disk storage!
3. HDD as in the manual switch
3.1. When switching 5sec power button and hold until a beep is heard, then release!
4. External hard drive into the USB Stecklatz 1 Kontroler with cable in slot 2
5. Start and Select buttons simultaneously press and Playsie aktualiesiert!
6. Playsie succinctly setting
7. Again old hard drive clean (ie step 3 again!)
8. with the old hard drive a backup on the external hard disk storage. (Took nearly 2 hours with me!)
9. Step 3
10 External Hard Drive to the Playsie and Data Recovery (where you where you made the backup!)
Can take at least as long as the backup!
11. Your data should now be transferred, have fun!
On the PC-professionals, I know it certainly is an easier and quicker but as already mentioned, I am not a genius as far as the PC but I did it!
