Error 1604 - Can't restore after 2.0 upgrade

I have already reported this problem to Itunes and made a visit to the "Genius Bar". It was bricked during the firmware upgrade to 2.0 and all the Genius bar could do is restore it to the previous firmware even though I have a receipt showing I purchased 2.0. Ugh!!
Anyway, in searching my hard drive, I cannot find the 2.0 firmware and it looks like it never downloaded in the first place. I have searched for files with ipsw extension and there's nothing, anywhere. Are you allowed to download again for free? Maybe this is why it bricked trying to load a file that wasn't even there? Any insight and/or help greatly appreciated!

People who have still not solved error 1604 and had a bricked iPhone no matter what they tried, might manage to revive it by following these instructions (on how to downgrade from 2.0 to 1.1.4).
You will need the following:
- iTunes 7.5 (NOT 7.7)
- iPhone firmware iPhone1,11.1.4_4A102Restore.ipsw
Step 1:
Uninstall iTunes 7.7 completely if you have it and restart your computer.
Step 2:
Install iTunes 7.5
Step 3:
Your iPhone should be in 2 states, either stuck on the "Slide to make emergency calls" screen, or you tried to restore before and it's stuck on the new look "connect to iTunes" screen. Either way you're ok.
Enter the phone in DFU mode (You must have the iPhone connected to the computer and iTunes running). To do this, hold the power & the home button down for about 9 seconds.
Why 9s? Well people say 10s, but it depends how slow you are at counting. Too short and it doesn't work, too long and the apple logo appears.
When you hit about 6-7s the screen should turn off, leave it for 2 more seconds and release the power button, STILL holding the home button. If all went well, you should NOT see an apple logo, the screen should be dead.
Keep holding home until windows/Mac informs you that it's found new hardware, OR iTunes tells you that your iPhone is in recovery mode. Remember, screen should be blank.
If you see an apple logo, repeat the process for less time until you get it right. Took me a little time.
Step 4:
Shift/Option click the restore button in iTunes and select the iPhone1,1_1.1.4 firmware you downloaded.
Fingers crossed it should restore back to 1.1.4.

Error Code 2300 on Restore after failed Os4 upgrade.

Pretty simple. Attempted to upgrade to the new Os4 with a 2nd gen iPod touch. For whatever reason, iTunes recognizes it, but the update failed which sent it into recovery mode. After 6 attempts at a restore, error code 2300 doesn't fail to pop up while preparing the iPod for restore. I've also tried 3 different USB ports- aiming for different computers later in the day. I don't want to have to invest money into a newer iPod - even though this one is 1 1/2-2 years old just about. Thankfully music is on the computer happily waiting to be loaded back in - so the only issue is getting the iPod itself to restore or SOMETHING. Paper weight - no thanks.
Any help is appreciated.

I have the same issue. from what i've gathered the issue is with the data transfer via usb

Can't restore after trying to upgrade to iOS 4.0.1

I tried installing the 4.0.1 update but it stopped downloading when the bar was about 70% full. Eventually I decided to disconnect the phone, knowing that I would have to restore. However, while trying to restore, it stopped again at about 70% full.
I have updated to the newest iTunes
I restarted my computer
I changed the USB cord
But nothing happens. All it says is "restoring iPhone software", yet it has completely stopped syncing

Error 14 is not a USB problem, but a CRC problem of OS image.
Image is corrupted.
Delete it (.ipsw) and it will worked well

thanks for your kind help

1. Update iTunes - latest version is 10.4.1.
2. Disable ALL security apps (firewall, antivirus/spyware) running on your computer.
3. Don't try to downgrade the iOS version. This isn't supported
4. If you EVER tried to hack thie phone or use apps like tinyumbrella, you may have to edit the hosts file on your computer to remove references to gs.apple.com
5. If your phone has been hacked (jailbroken, iOS downgrade, or unauthorized unlocking), you may not be able to restore the phone to Apple specs again.
"This device is not eligible for the requested build: Also sometimes displayed as an error 3194. If you receive this error, update to the latest version of iTunes. 3rd party security software or router security settings can also cause this issue, to resolve please follow Troubleshooting security software issues. Downgrading to a previous version of iOS is not supported. If you have installed software to perform unauthorized modifications to your iOS device, that software may have redirected connections to the update server (gs.apple.com) within the Hosts file. For steps to edit the Hosts file and allow iTunes to communicate with the update server, see iTunes: Troubleshooting iTunes Store on your computer, iPhone, iPad, or iPod; follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > The hosts file may also be blocking the iTunes Store. Also, using an older or modified .ipsw file can cause this error. Try restoring moving the current .ipsw file aside, or try restoring in a new user to ensure that iTunes downloads a new .ipsw."

Can't activate after latest iPad upgrade. Advises me to go to iTunes but it won't get off the error screen.

Can't activate after latest iPad upgrade. Error message advises me to go to iTunes but it won't get off the error screen.

I am the original owner of an ipad and it woke it yesterday requiring me to activate it using the original apple id used to set it up.
It will not accept my apple id and password.
It does not show up in my icloud under devices.
I have tried hard restart (home + power) and itunes recovery.
I am out of ideas and have not found anything for original owners (as opposed to someone who bought it from someone else). I did see some posts from last year where a few people had the same problem and took it back to apple and got a refurbished unit given to them since customer service and engineering couldn't fix it. I was wondering if this was related to the recent ios8 upgrade. Anybody else have ideas or same problem before I hike down to the apple store for mercy?

When I try to update my ipod touch from 4.2.1 I get an error 1604 can someone help?

I had previously installed ios5 to see it and then downgraded my ipod back and now I can't upgrade.

Error 1604: This error is often related to USB timing. Try changing USB ports, uninstalling and reinstalling USB ports, and other available USB troubleshooting steps (troubleshooting USB connections, device not recognized properly, computer won't recognize a FireWire or USB device). If you are using a dock, bypass it and connect directly to the white Apple USB dock connector cable. If the issue persists on a known-good computer, the device may need service.
If the issue is not resolved by USB isolation troubleshooting, and another computer is not available, try these steps to resolve the issue:
Connect the device to iTunes, confirm that the device is in Recovery Mode. If it's not in Recovery Mode, put it into Recovery Mode.
Restore and wait for error 1604.
When prompted, click OK.
Close and reopen iTunes while iPhone remains connected.
iPhone should now be recognized in Recovery Mode again.
Try to restore again.
If the steps above do not resolve the issue, try restoring using a known-good USB cable, computer, and network connection.

Also, look at the article for stuff about the hosts file since you may have to get that back to normal since downgrading usually requires changing the hosts file.

BBM contacts restore after an OS upgrade from 7.0 to 7.1

Torch 9810, OS 7.1, SD card support with 14G free space
After an upgrade of BBM8.5, my phone could not complete booting fo several time until I flashed it but with OS7.0, this did not restore my BBM contacts; I used my computer to restore phonebook contacts and other data but BBM contacts still was not loaded.
I re-installed BB8.5, still to no avail. 3 days later I was re-prompted to sign in with my BB ID and I got all my 181 BBM contacts back. (Is this a remotely initiated action?)
After this I re-installed BB OS 7.1 and again I lost my BBM contacts. I have tried everything possible to get these BBM contacts but no way; but I am sure it is somewhere in RIM remote server.
These are my questions:
Does BB OS 7.1 supports the easy backup and restore of BBM contacts just as it does for phone contacts?
Can you make it easy for BB users to be able to restore BBM contacts as it is possible with phonebook contacts?
On the custom restore option on the BB Desktop software, what is tab to select for BBM contact restore after an upgrade/update?
Does Blackberry protect saves BBM contact details?
Is there an unshared info/law that must be respected in getting back BBM contacts, like "wait 72hrs after an upgrade before getting back your BBM contacts?????????
I do not have problem with Phonebook restore at all. That comes easy with my computer back-up but BBM contacts restore is a pain in the neck! Please help.
NB: I need to add that various suggestions seen on the site have not worked and I saw that my suffering on BBM contact restore is almost becoming an epidemic!!!

ITunes error 13/14/1604, Can not restore my iPod Touch

Hello,
My iPod Touch crashed when using a app, so I did a hard reset.
After that it displayed the "Connect to iTunes thing"
The problems started that
So I connected it to iTunes, and it said that it couldn't make a connection because of my password.
There was no way to enter the password though, because of the connect to itunes picture.
I've put my iPod in DFU mode, and then tried to restore.
It gave a unknown error (14)
I asked on some forums and they gave me some tips, I tried them, got a 1604 error, tried to restore again, got a 13 error.
Now I keep getting an 14 error
I have no idea what to do now, I do not have any warrenty, since the water indicator is not the color it should be.
But that happened 4 months ago, and all the time it worked perfect
Can someone please help me out

Ok. I have spent the last 8 hours researching this problem and have the absolute 110% answer to everyone's problem with this issue.
Error 13 and 14 : Are checksum problems with the firmware image that is in the update package.
The update package is a .ipsw (IPod or IPhone SoftWare). This file is actually just a .zip renamed .ipsw.
The error is caused by a failure to download a crc-free version of the file. Not really sure why there are so many crc problems with the iphone updates, but Apple does not check the integrity of the update package before wiping your current version of IPhone software and that is why all IPhones that start an update with a bad update package end up in recovery mode. These errors are NOT related to the iTunes installation, antivirus software, or firewalls.
Recommendation : use a program like "Object Fix" (Freeware) to verify the integrity of the file prior to commencing with any new updates. You will have to keep trying to download it until you get a error free file. Once you have a CRC error free file this problem will go away. (I thought TCP/IP helped get rid of CRC errors.)
I had another problem and that was...
Error 1603 and 1604 : These are USB driver connectivity problems.
Recommendation : FULLY uninstall and re-install itunes software as stated in the Apple support documentation. Be sure to reboot between each step and these problems should clear themselves up. In addition, firewalls and anti-virus software may cause these errors as well.
Finally, shame on apple for not properly documenting their software so that end users do not have to decrypt their error messages with no true support to solve the issues. These are problems that enough people have had that there should be specific documentation on these problems.

Error 21 unable to restore after update

Hello,
I recently tried to download the new update as it pestered me everytime I plugged my iPhone in (think it was 4.1). It failed, and as a result it said that I had to restore my iPhone. So I go to restore it and now it says unable to restore (error 21).
I literally have no clue what's going on. Anybody out there offer me any suggestions or advice on how to fix this problem?
Thank you for your time!

*Error 20, 21, 34, 37:* These errors typically occur when security software interferes with the restore and update process. If you are using a PC, follow this article to resolve this issue: http://support.apple.com/kb/TS3125 .

*Basically you need to disable your Anti-virus software and then do a DFU restore.*
*How to DFU Restore.*
1.) Open iTunes and connect the iPhone.
2.) Press and HOLD the Home button AND the Sleep/Wake button at the same time.
3.) After the screen turns off, +LET GO+ of the Sleep/Wake button and +CONTINUE HOLDING+ the Home button.
4.) iTunes will pop up a message telling you that it has detected an iPhone in Recovery Mode. (You can let go of the Home button now.)
5.) Click 'Restore' to restore your phone to Factory settings.
Also, try updating to the latest version of iTunes before you do this.

BBM 7 Problems - Can't restore after OS Re-install

I had to reinstall my operating system due to problems I was having. I had BBM 7 on my phone.
When I restored everything, it all seemed to work fine... then I went to BBM, opened the app and for an hour now I've been stuck in this loop without anything happening ... even going so far as to selectively restoring BBM from my back up file. Here's a screen image of what I am seeing. I can't even get into the app.
Any help would be appreciated.

I'd suggest this, in this order.
Do a simple reboot on the BlackBerry in this manner: With the BlackBerry device POWERED ON, remove the battery for a minute, and then reinsert the battery to reboot. Then, try the BBID login again and allow BBM to restore.
Remove BBM7 by deleting it from your BlackBerry at Options > Device > Applications Administration. Scroll and find it and delete, and reboot again as described above. Then, after reboot, go to www.blackberry.com/bbm and download BBMessenger again and login your BlackBerryID. (I'd recommend doing this while connected to a WiFi source, but it shouldn't matter, just make it faster).

Error 6 can't restore iphone

i have two iphone and now both show the same message as can't be restored error 6 any suggestions? please help thanks

Try this: Shut down your Mac and disconnect all USB and peripheral devices. Restart your iPhone by holding down the sleep and home buttons for about 10 seconds. Connect the iPhone to your Mac directly - no USB hubs, etc. Power up your Mac. iTunes will prompt you to restore. Click okay and it should be good to go. The main thing I noticed with this fix is that there can't be ANYTHING other than the iPhone connected to your Mac. Hope that helps!
