Situation:
Iphone firmware 1.1.1, was jailbroken and working. I have had several calls, had connenction to the Internet, and everything was working.

I was installing new phoneformat and keyboard, when my Iphone froze.
I connected to Itunes (ver. 7.4.2.4) to restore firmware to 1.1.1, and gets everytime the warning "Iphone, could not be restored. Unknown error (1604)."

I have restarted computer, software and Iphone, and still get the same result.
Does anyone have any suggestions to how my Iphone could be restored.

If you have Windows, run iBrickr 0.91. It always does the trick for me, should fix it for ya...

I do have Windows, and I ran iBrickr 0.91.
iBrickr could not make a connection to Iphone.
Iphone constant request firmware update.

How do I restore/reload the FW, when i get the error everytime i use Itunes.

Try uninstalling iTunes
Restarting Computer
Reinstalling iTunes
Different USB Port

Allright, new Scenario. On a new (different) computer, I tried:

1. Installing Itunes (ver. 7.4.2.4), and restarting computer and Iphone.

2. I tried to install FW 1.1.1 via iTunes, and got same message "Unknown error (1604)."

3. Tried to upgrade to FW 1.1.2 via iTunes. New error iPhone could not restore. Unknown error (-50).

4. Installed and ran iBrickr v0.91. Selected "Reboot Iphone" but Iphone display stay Green (which means, Iphone should be restored via iTunes).

Any suggestions on how I got corrupted FW reloaded....?

I can solve 1604. I had it too. All I did was to remove the sim card in the iphone, restart the iphone and pc, and voila, it works fine. Im on Vista Ultimate with iTunes 7.5

to all with 1604 error

i solve this problem

1. clean all usb contacts / female usb computer,male usb cable and iphone connector/ very important
2. eject sim card from phone and put iPhone in flash mode hold center + power , after that run iBrick . enter downgrade to 1.0.2 / firmware 1.0.2_restore need to be in folder with iBrick with name 1.0.2.ipsw/
3. the phone will be light with white light
4. start iTunes , hold shift key and restore / restore firmware need to be high version , like this dead unit is a 1.1.1 , new restore version 1.1.2 /

and now unit alive with 1.1.2 firmware

B.R.
