I have a Galaxy S Captivate and it has been problematic ever since. I flashed various stock roms (with and without bootloaders) in download mode and the phone always gets stuck at the boot screen (AT&T logo).
Here is a video posted by someone else which shows the same problem I'm facing.
I'm guessing that I messed up the bootloader and I need to reflash/fix it somehow but can't seem find a specific targeted tutorial/guide for this issue. Any help is appreciated. Thank you.
