Seeking some more technical assistance here - having spent the last 6 hours trying to update my current 4.3.3 to 5.1.1. Including hours and hours on google finding NOTHING.
I've tried TinyUmbrella w/ iTunes, and RedSn0W to update the ISPW.
RedSn0w demands SHSH blobs from my current 4.3.3 firmware, which i can't seem to obtain. 5.1.1 is available through Cydia and TinyUmbrella. But no way to get ahold of my own 4.3.3.
I've installed iSHSHIT on my iPad. Tried to get my SHSH blobs - but "no longer signed by apple".
Updating with Tunes / TinyUmbrella only gives me a 1600 error.
