I'm new to jailbreaking, so I followed the guide on this website very carefully. I have a 4th generation iPod Touch (5.0.1). After jailbreaking successfully and trying it out, I now want to remove the jailbreak. I found the FAQ about this, which says to use iTunes to first bakup then restore the iPod. The 1st problem I'm having is that when iTunes tries to restore the device, it warns me that the latest iOS (5.1) will be installed. Having read the FAQ on this site about SHSH, I know that it's unwise to upgrade to 5.1 if I ever think I will need to jailbreak again (which I might want to do). Therefore, I believe it's recommended that I save my SHSH to my computer in case I want to revert back to 5.0.1. So, I tried following the directions using TinyUmbrella with these options:
After doing this, I tried going into the terminal to see if it saved any files (using
So, as you can see from the log, it seems like it hasn't stored the SHSH files.
For #1-3: You probably did the jailbreaking process correctly, but Cydia couldn't save your blobs since Apple is no longer signing iOS 5.0.1. You can investigate grabbing partial blobs using redsn0w or iFaith. See this guide to SHSH blobs - I'll quote the most relevant bits:
For #4: You can't use "Erase all content and settings" on a jailbroken device - because of the different filesystem on a jailbroken device, tapping that button messes things up and causes your device to get stuck at the Apple logo while booting - meaning that you'll have to restore with iTunes anyway.
