Error 37 after iOS 4 upgrade

I upgraded this morning to iOS4 on my second generation iTouch. After the download, the OS started installing on my device and right before the end it popped up error 37 and it said there was a error and I had to restore. After 5 restores it always stops with that message. My iTouch doesn't even turn on now, is downgrading my best option at this point?

My iPod 2G became a paper weight after trying to upgarde to iOS 4.0 from 2.2.1.
The upgrade exited with error code 37.
Also, my iTunes din't recognize the iPod while connected to it via USB
The culprit was indeed the ZoneAlarm firewall...
Turn off all third-party firewalls before upgrading to iOS 4.0. iOS 4.0 doesn't like some of these firewalls.
I got the iPod to DFU mode...pressed the sleep/wake and home buttons for 10 seconds, then released the sleep/wake button and held the home button for another 10 seconds. iTUnes recognized the device and said it found the iPOD that is in recovery mode.
Clicked the Restore button for a successful restore.
Then, it gave me a choice to either restore the iPOd from my backup or present a fresh iPOD.
I got all the data restored.

Cheers !!

Buehler... Buehler?

Man, I'm getting mad. After messing with it for several hours, I've gone from error 37 to now error 9. Although, I'm sure error 37 is still the issue. Blergh!

Jeez, I should read ALL the replies before posting. Zone Alarm was the culprit for me as well. I DL'd the newest update, turned off my firewall and disconnected from the interwebz and everything updated just fine.

I had the same problem - switching off Zone alarm and re-trying a restore on my Iphone 4 worked afterwards.

I think its just crap that I have to disable my firewall, making my entire computer vunerable every time I attempt an update.

I HAVE SOLVED IT!! Just switch off Zone Alarm (or in general the FireWall) and rename the file "iPod3,14.0.2_8A400Restore" to "iRest" it will work! (sorry for my english!)
