I did - I didn't find any relevant information.
Phone is not jailbroken. I tried different USB ports.
Saying "you couldn't have done a search" is not helpful. I wouldn't have posted if I had searched and found the information I needed.
You're kidding me right? There's 5+ threads RIGHT NOW asking the exact same question.
Obviously you did not search even a little bit so you deserve no help. There have been over 11 answers in the 5+ threads explaining why this is happening.
And that's only HALF way through the first page of Threads in this sub forum. You can't be that blind.
That is not the error I'm getting. I downloaded the update just fine... but now it won't even turn on it gives me an itunes logo and usb cable. Attempting a restore I just get the error I wrote in my OP.
Nothing in those threads have anything to do with my original error. I could be mistaken as I'm not too savy on this but the update downloaded...
Tried update from the wi-fi and it failed so that's when I tried to do it from iTunes and still no go. It downloads and starts to install but after I get that error and the screen shows an iTunes logo and USB cable.
The iTunes logo and USB cable is telling you to plug into iTunes. Try that and see iTunes needs to restore something. You will likely get a message from iTunes when you connect telling you what's going on. Worth a try.
EDIT: Be sure to update your iTunes before doing this. iTunes also has an update to make it compatible with the 5.1.
Any update? I update through wifi, phone went to connect to itunes screen, go through restore, get unknown error occurred (1) message and have tried all 5 suggestions in the "resolving update issues" page from Apple. I also have a Verizon iPhone 4.
