IPhone 2G hangs at "slide to unlock" - restore not helping

Hi,
Here u can follow the steps

Step 1: Make sure you have downloaded the latest version of iTunes if you haven’t already. Download iTunes 8.2 from the link given below.
Step 2: Now connect your iPhone with your PC. You must connect it to a single usb port on the backside of your computer. Do not use any usb hub or the ports in the front as this could cause an error during update process.
Step 3: Start iTunes 8.2. Sync your iPhone with your PC so that iTunes backs-up all your important data including settings, apps, music, contacts and photos.
Step 4: You will now have to download a custom cooked firmware for your iPhone version (2G or 3G). I can’t post the download links for these files for the reasons you all know very well. Just Google “iPhone 2G Custom 3.0” (If you are using iPhone 2G) or “iPhone 3G Custom 3.0” (If you are using iPhone 3G) and use one of the torrent links to download the custom created .ipsw file.
Step 5: Once you have downloaded the required .ipsw file, Copy/Paste it into this location:
“C:\Users\[username]\AppData\Roaming\Apple Computer\iTunes\iPhone Software Updates\” (Windows 7)
“C:\Users\[username]\AppData\Roaming\Apple Computer\iTunes\iPhone Software Updates\” (Windows Vista)
“C:\Documents and Settings\[username]\Application Data\Apple Computer\iTunes\iPhone Software Update\” (Windows XP)
Step 6: Restart iTunes. You will now be prompted to install this firmware you just download. Just close this prompt dialog by clicking on “x” from the top right-most corner of the window.

Step 7: Now you will have to restore your iPhone to this custom firmware 3.0 that you just downloaded. Click on your phone from the sidebar in iTunes to get to this screen as shown in the screenshot below:

Now press and hold left “Shift” button on the keyboard and then click on “Restore” (Not “Update) button in the iTunes and then release the “Shift” button.

This will make iTunes prompt you to select the location for your downloaded custom firmware 3.0. Select the downloaded .ipsw file and click on “Open”.
Step 8: Now sit back and enjoy as iTunes does the rest for you. This will involve a series of automated steps some of which are highlighted below:

Don’t do anything silly at this point. Just wait while iTunes installs the new firmware 3.0 on your iPhone. Your iPhone screen at this point will be showing a progress bar indicating installation progress. After the installation is done, iPhone will restart automatically and you should now have a fully unlocked and jailbroken iPhone 2G. iPhone 3G on the hand will only be jailbroken, not unlocked. iPhone 3G users will have to wait for Dev-Team to release ultrasn0w on Cydia in order to unlock their phones.
Step 9: Once you are done with the unlocking and jailbreak process. You can now restore all your settings, apps, music, contacts and photos to the newly installed firmware version 3.0 by restoring the backup that you made in Step 3 from iTunes.

Feel free to ask me any question here should you run into any problem during the update process.

Try browsing this site. Use the forums. Also, post more info on what exactly was done to your phone. Include version numbers.

Before you connect your iPhone or iTouch to iTunes.
Try and put the device into DFU Mode.
Plug your USB cord into your Device and Not into your computer.
Turn the Phone all the way off by holding the power button until the Red Bar appears and Slide it off..
Hold the "Home" Button Down for 5 seconds.
Then Push and Hold the "Power" Button while still holding the "Home" button and count to 7
Let go of the "Power" button while still holding the "Home" Button and Hold the Home button for approx 26 seconds.
The screen may or may not go blank with lines. No Worries!! now plug the USB into the computer with iTunes open. If the iphone is in DFU mode, iTunes will come up with a popup that says, "Itunes has detected an iPhone that is in recovery mode. Your must restore it"
Once this occurs, you can restore your device with any firmware by pressing "SHIFT" on your keyboard and "Clicking" Restore with your Mouse. Restore your device and let it mount to itunes.
If you are unlocking the device, I would suggest using "QuickPwn" you can get it HERE
You can download Apple iPhone Firmware HERE, when using quickpwn you will need to upgrade your firmware to 1,2_ 2.2_5G77...NOT 2.2.1
(TIP: Don't restore your iphone with custom firmware in iTunes. Restore with the original Firmware and Unlock or Jailbreak letting Quickpwn make the custom firmware....Also if you have a 3G do not ungrade in itunes to the 2.2.1 firmware, it changes the phone modem baseband and renders it "NOT" unlockable)

I would suggest reseotring it once more and trying to use quickpwn again. If it fails you may alternatively want to use Winpwn, it basically does the same thing.

its not a hardware problem brothe as i am also facing same problem...actually it all happen with jailbreaked iphone...ad i'hv checked its deep root directory there an application called "lockdown" is the main cause of that...nd still there is no crack of that.....
two days back i unlocked my iphone 2g it was working properly before that i was facing the same issue as you are facing....but now again it went to the same problem....
i hav a temp solution of that...
use blackra1n u can find it from blackra1n.com
nd for few seconds slide to unlock will work
or u can use it by connecting it with ur itunes ...connect usb wire nd slide it again nd again...u can unlock it..bue its just temp

Put iphone into DFU mode. you can do it by iphone software or handy. then restore it by itune (NOTE. delete itune folder in your Mymusic forder (in the my document) itune will make a new one when you open it again )if you get error .open ibricker to get out of recovery mode.

I have an iphone that does this at times too! I have to reboot it periodicly, seems more often when I use it a lot. I have found several issues with winterboard and plugins for it to cause some of my problems. might try changing your screen to normal and see if it still acts this way.

not really sure what your asking do you have the 2.2 iphone update?
if so download Quickpwn it works for the iphone 2.2 update. real easy.

Hi,

two questions:
1. Do you use Mac or PC??
2. What version is your Iphone on now? 2.2?

Dont worry as of today ANY iphone on ANY version can be unlocked.

Im pretty sure that Ziphone is not uptodate anymore.
I recommend Pwnagetool or Quickpwn to unlock/jailbreak current versions of Iphone software.
