I have an iPad2 wifi+3G on iOS 5.0.1 and already jailbroken.
I'd like to upgrade to iOS 5.1.1 and for doing so I've downloaded the 5.1.1 firmware from iClarified and Redsn0w too. I've lauched iTunes (v. 10.7 under Win7 64bit, fully updated) and I choose the option the restore from my local firmware but I got an error 3194.
At this point I modified the host file and resolved the issue but then I got another one: unknown error 21 and the device remained in recovery mode.
Then I lauched the Redsn0w prog (v. 0.9.14b2-win) that helped me exiting the recovery mode and now the device is back to normal functionality but still on v. 5.0.1 .
Now the question is pretty simple: how can I restore (even without using iTunes) to the 5.1.1 firmware? is there a SAFE and effective procedure to upgrade and then jailbreak again the 5.1.1? even using just Redsn0w alone orsome other bunch of progs?
Thanks in advance for all the infos.
have a nice day,
