iPhone 3GS doesn't boot after "Clear all Content"
A friend of mine gave me a jailbrokeb 3GS iPhone and because all his info was there I decided to clean everything using the "Clear all Content" option.
After this, the iPhone entered in a reboot loop and only showed Apple logo. After this I searched a lot on the Internet and tried lots of stuff and nothing seemed to work.
I don't know which version of iOS he was running neither the baseband. One of the things I did was using redsn0w to upload iOS 4.3.3. The process seemed ok but in the end I still have the apple logo and nothing more.
I'm desperate to have the phone working but I don't know what else to do. Any help will be great.
Thanks in advance.
