Figured that K5-Thing out already
Is it a problem with the two different PW versions?
Another question, I'm sorry I have so many of them. I jailbreaked my device now and in the wiki it says I should install usbnet now, to make a full backup. That sounds reasonable and I'm a fan of backups.
However in the instructions it also says, that I should have the knowledge of a linux CLI sysadmin which I certainly don't have (at least some knowdledge though).
What would you suggest me to do? Is there an easier way to do a backup? Or in case I don't have a backup: Will it still be possible to restore my device if broken somehow? I'd not care too much about the personal data that would be lost.
If yes, I'd leave out the usbnet part I guess, and go straight to MKK, KUAL and probably one or two other things that seem useful.
