In order to "restore" to an ipsw you must have shsh blobs for that firmware either on file with Cydia or locally using TinyUmbrella. This means that the device would have to have been previously jailbroken at or before the desired iOS version. Someone please correct me if I'm wrongPlease correct me if I'm wrong.
if I'm not mistaken, Apple no longer signs 4.1 so that won't work unless you already have your shsh blobs saved and you redirect the signing verification url in your hosts file.or you download the ios 4.1 file from felixburns.com
go to iTunes
klich restor while holding the shift button
an select the ios 4.1 file
Perhaps you should have watched that video before posting it. It "does" require you to have your shsh on Saurik's server and he even mentions this at the very beginning of the tutorial.there is another way shown on youtube whitch works
without the shsh thing
chet it out
You realize no one here is going to believe you unless you provide some evidence other than "search by yourself". All signs point to having a shsh on record, even from the jb devs themselves, even from your own posted youtube link, and other youtube searches. just sayingno its not the only way
What's the history behind redmond pie? Their signature says Microsoft, Google and Apple and yet it seems to be such a strongly cited Apple source.I would go ahead and and update to 4.2, indications from the dev team are that there untethered JB won't need the old blobs. It runs well like 4.1 and will allow you to use the free "find my iPhone ".
