First of all, you can't downgrade the firmware, so you might as well stop trying to do that.
See if you can force the phone into recovery mode:
Leave the USB cable connected to your computer, but NOT your phone, itunes running, press & hold the home button while connecting the USB cable to your dock connector, continue holding the home button until you see “Connect to iTunes” on the screen. You may now release the home button. iTunes should now display that it has detected your phone in recovery mode, if not quit and reopen iTunes. If you still don’t see the recovery message repeat these steps again. iTunes will give you the option to restore from a backup or set up as new.
well , i'm in the recovery mode , and i'm stuck in it
and itunes detected my iPhone and i've got the message that says : You must restore your iPhone before it's ready to use , and the only activated Restore Button , and i've clicked Shift + Restore , Browse for the IPSW file , and selected it , it's all great , iTunes has verified my firmware with apple and continue the restoring process , but when " Restoring your iPhone is 2% "
i've got the Error Number (14)
that's exactly my problem
and by the way , the country option in the sittings , i thought that it's (where are you) not (where are you from)
well , i've done all of 'em
but this one
5.There may be third-party software installed that modifies your default packet size in Windows by inserting a TcpWindowSize entry into your Registry. If your default packet size is set incorrectly it can cause this error. Contact the manufacturer of the software that installed the packet size modification for assistance.
because i didn't understand it
The TcpWindowSize entry determines the largest TCP receive window that the system offers. The receive window is the number of bytes a sender can transmit without receiving an acknowledgment. This entry overrides TCP's negotiated maximum receive window size and replaces it with the value of this entry.
But how this helps you, I have no idea.
I'm out of suggestions. If you have someone available that has a Mac or any other computer, you could try restoring as a "new" device on that computer. Of course, you'll lose all saved data doing that, but at least your phone would work, if successful. You could then re-sync your itunes content back from your computer.
and i've tried to restore the iPhone on my father's laptop (Toshiba)
and it didn't work
It's starting to look like something is blocking itunes ability to stay in contact with Apple's servers...re-read the support article I referenced you to, especially the part about what ports need to be open...
but it successfully verified the Restore file with Apple
and when the status is restoring iPhone and the progress bar on the iPhone's screen
it's only about 2% and then i have the Error 14 or 13
and i don't know , if i restored my iPhone from a downloaded IPSW file or let iTunes download it would make a deference
Click START / Run
Type in "regedit" and click OK to start Registry Editor
click Edit>Find TcpWindowSize
You'll find "TcpWindowSize" entries in the Registry.
File>Export and name whatever to backup them up in case you need later
go through process until no more found
When they are all deleted close Registry Editor
Restart Computer and test.
