Yep! Its not only me who bricked his iPhone 4 while restoring iOS 4.3.3 CFW but many people in comments (8ardock, NickyS, Komrad) also reported that they are unable to restore stock or custom iOS 4.3.3 IPSW on their iDevice. If you got iTunes error 1611, error 14, error 9 or error 28 while restoring iOS 4.3.3 firmware then it means your iDevice is bricked and you might never be able to use it again.
My Case (Error 14)
My iPhone 4 was fully jailbroken and unlocked on iOS 4.2.1. Last night i tried to restore iOS 4.3.3 custom IPSW made with Sn0wbreeze 2.7 but ended in error 14 :( This is what the official iPhoneWiki page says about error 14:
You have to restore the device with a custom firmware. Update to a custom firmware isn't working. Device isn't bootable.
Yes, i tried to restore iOS 4.3.3 custom IPSW made with PwnageTool and Sn0wbreeze but nothing worked. Still getting error 14.
USB Problem. Check the USB connection and try other direct ports or maybe the USB cable is an older one. Device isn't bootable.
I not only tried to restore by changing USB ports but also tried different PC. Bought new USB cable and then tried on Mac. Still getting error 14.
You're trying to 'update' to a beta firmware instead of performing a restore.
Oh common! I am restoring iOS 4.3.3 final build on my iPhone 4.
Device is still bootable if you kick it out of recovery mode.
Tried Recboot, TinyUmbrella and TU (Fix Recovery) but nothing worked. Restoring iOS 4.3.3 stock or CFW both return error 14.
8ardock (Error 14 & Error 9):
8ardock tried to restore stock iOS 4.3.3 IPSW to un-jailbreak his iPhone 4. When the progress bar reached at 35%, he got error 14. Later he tried to downgrade by restoring iOS 4.1 IPSW but ended up in error 9. Here is what iPhoneWiki page says about error 9:
Seems to be a kernel panic. After patching kernel in PwnageTool with custom patches, restore failed with this. iRecovery then showed increased kernel panic count.
NickyS1290 (Error 1611 & Error 28)
While restoring iOS 4.3.3 custom IPSW on iPhone 3GS (iPad Baseband), Nicky got error 1611. Tried to use Recboot and TinyUmbrella (Fix Recovery) to kick her iPhone 3GS out of recovery mode loop but nothing worked. Tried to restore her iPhone 3GS using iOS 4.3.3 CFW again but ended in error 28. Here is what iPhoneWiki page says about error 28:
Hardware error. Return your device to Apple if possible. The problem is a bad dock connector on the iPhone. Must change the connector. If you have tried almost everything, reset the logic board (leave uncharged for five days or remove battery for half an hour), then pwn and restore. if this doesn't work, the "hard disk" of your iPhone is damaged.
Komrad (Error 1611)
Restoring stock iOS 4.3.3 IPSW on his factory unlocked iPhone 4 resulted in 1611. This is what iPhoneWiki page says about error 1611:
iTunes tried to enter the Restore Mode, but the device turned back to the Recovery Mode.
UPDATE 1: Komrad managed to solve the issue by changing the battery of his iPhone. So if you are getting iTunes error 1611, get your battery replaced.
UPDATE 2: According to Komrad, the root cause of his dead battery was his car-charger. After buying a new battery, he did manage to escape iTunes error 1611 but later found his iPhone dead *once again* when he tried to charge his iPhone using his car-charger.
