Following this thread with interest. The main concern I have with the process is backup NAND. How is this done as it is not something I have any experience with?
Thanks.
The NAND back up is the easiest part of the process
Basically, ensure you are on the latest official firmare
You find an old crappy USB stick (I think you stay clear of a USB 3 stick?) and make sure it is Basic, MBR, FAT32 formated.
You downloa the very small sized file from the first page of this thread and extract it to that usb stick
You put the stick into the front USB slot and your player should report that it has seeen the usb stick
You don't have to do anything more except leave it plugged in that front port for a while (I left it in about 5 mins) and then remove it and check on your PC that there are 23 files written on the stick
If there are, then that is the NAND backed up
I made a couple of copies of the files and stored them safe and that is how simple that part is
Once I had installed the jailbreak firmware, I did another NAND back up
So I have two seperate NAND backups, 1 before the jailbrake and 1 after the jailbrake
I am hoping that I never need them at all in future
