iPhone Firmware Downgrade Offers Hope, Then Disapointment

I can’t help but feel a little bit sorry for the poor ol’ souls who went and spent how many hundred dollars on an iPhone, then got it unlocked, then with the new firmware update had their lovely piece of walkin’, talkin’, sleek ‘n’ shiny moolah turned into a fat (when compared to the iPod Touch) brick. Today, though - Downgrading instructions have surfaced… No phone features have been returned yet, but at least you can get all your 3rd party applications back. You can’t say Apple didn’t warn you, and I quote;
Apple has discovered that many of the unauthorized iPhone unlocking programs available on the Internet cause irreparable damage to the iPhone’s software, which will likely result in the modified iPhone becoming permanently inoperable when a future Apple-supplied iPhone software update is installed. Apple plans to release the next iPhone software update, containing many new features including the iTunes Wi-Fi Music Store (www.itunes.com), later this week. Apple strongly discourages users from installing unauthorized unlocking programs on their iPhones. Users who make unauthorized modifications to the software on their iPhone violate their iPhone software license agreement and void their warranty. The permanent inability to use an iPhone due to installing unlocking software is not covered under the iPhone’s warranty.
Anyhow, here’s Gizmodo’s set of instructions. If you head on over to their site, you’ll see a video tutorial has been posted additionaly.
• Make sure you have a copy of the 1.0.2 firmware “iPhone1,1_1.0.2_1C28_Restore.ipsw” stored in: “youruser/library/iTunes/iPhone Software Updates”
• Reboot iPhone holding the top button (power) and the home buttons.
• Release the top button 10 seconds after that, right after the screen goes dark. But keep the home (bottom) pressed for a while.
• The iPhone screen will appear to be off. Now start iTunes manually.
• iTunes will tell you it has found an iPhone in “restore mode.”
• Press option key and then click the restore button.
• Select the 1.0.2 firmware .ipsw file from here: “youruser/library/iTunes/iPhone Software Updates”
• The phone will restart and there will be an error out at the end. Don’t worry. It was bound to happen (if the iPhone returns to Restore Mode instead of Activation Mode, then you may have to restore the 1.1.1 firmware, wipe all information in the iPhone and then repeat from above. But first, try to restart the iPhone.)
• Shutdown iTunes.
• Launch the latest iNDpendence (Mac-only for now.)
• Activate the phone using a expanded 1.0.2 file (to do that, make a copy of the 1.0.2 ipsw file, then select “Open with…” from the Finder’s action menu and use BOMArchiveHelper.app (it will appear in the menu.) The ipsw are really .zip files.
• It will flash all sorts of errors, but don’t worry.
• Activate the phone.
• It will show the SIM error but now the iPhone will work again with your Wi-Fi and your apps.
Long, eh?
