Hi guy, I have an iphone 3gs running on 4.3.5, i want to unlock it so i flash to ipad baseband and it stuck in the middle, after that i cant restore to any firmware even 4.3.5 or custom 4.3.3 baseband. I even tried tinyumbrella to exit recovery mode but no luck. Now it stuck in recovery mode and it seems like crack. Any idea, please help.
