Cannot restore/update iPhone. Internal error iOS5

Same problem as others on the iPhone4 update. Error code 3004. ITunes now doesn't recognize my iPhone and my phone just has the "spinning" circle. Any suggestions other than waiting? Do you think if I keep the phone plugged into the Mac and iTunes opens, it will recognize my phone and eventualy restore? thanks

Close iTunes, open Terminal and enter the command "dscacheutil -flushcache". Restart iTunes and restore/update.

That's what worked for me when I was stuck on the "Connect to iTunes" screen/3004 error.

Edit:

Just noticed you said Mac, deeeerrrr. My bad.

Mine too. It has a loop and Itunes can not find it. I tried to do a reset but it dont solve...

Same - Including not being able to update ATV2

I had 3004 error and was stuck. I think it was a corrupt ios 5 firmware download in my case.

1. Delete IOS 5 firmware from folder ~library/itunes/iphone Software Updates

2. Enter DFU mode ie. http://www.iclarified.com/entry/index.php?enid=1034

3. itunes will then re-download the firmware and restore the iphone.

No promises as I pieced this together from several sources but it worked for me. Good Luck.

Someone posted this:

"I just restarted my phone my holding the sleep/wake button and home button at the same time, once the apple logo comes up release the sleep/wake button and keep hold of the home button till the usb cable and itunes come up."

My iPhone is now again known by iTunes. But upgrade doesn'n work anyway. I'll wait untill tomorrow.

For those who don't wish to fool around in the Terminal, the solution for me appeared to be "wait a bit."

I got the same error as everyone else attempting to upgrade my iPhone 4 (running 4.3.5) to iOS 5. After two unsuccessful attempts, I waited an hour on the assumption that heavy server traffic was making the "verification" step unable to complete.

Sure enough, the third time was the charm. I made sure not to engage in any other bandwidth-using activities while the update was being downloaded, and that appears to have solved the problem. I'm now running iOS 5.

It may not solve everyone's problem, but I'm not surprised that a little patience turned out to be the key for me.

You know whats an easier way..?

Just make your device to be Factory setting then hook it up and restore!

Updated it in first try.. lol

I would just like to know what GENIUS put out all these updates at one time , i cant beleve Apple could be so STUPID an be caught out by this ?

Will try the 'clean' installation later once i reach office.

Hopefully, it works. I'm waiting for this updates for the longest time~!

If you never try, you never know.

After about 5 tries... I finally downloaded ios 5. Now, I cant restore my iphone. It says " Jeremy's Iphone restore has been interupted." Any ideas?

After I updated I got the error mentioned and now my iTunes won't even recognize my iPhone 4. Any similar cases?

Yes. Someone posted a solution that worked for me. I apologize to the poster but I can't remember his/her handle. Hold down the home button and the open close button ( located on the top right) at the same time. When the apple logo reappears, release the open close button, continue holding the home button until the iTunes and sync cable appear. iTunes will now regonize your phone.

I've tried that fix numerous times and no dice so I was hoping there was another way because I'm pretty much at the end of my rope.
