[Galaxy S I9000 Q&A, Help & Troubleshooting] AdamOutler:
Allow me to elaborate.

1. Never recommend that ANYONE use Odin for ANYTHING. Heimdall is much better. Odin causes bricks

2. There's 2 types of bricks. Hard brick and Soft brick.

Hard brick acts like it does not have any battery. It does not respond to buttons or button combos. It cannot be turned on in any way shape or form past it's PBL. USB is not recognized on the computer. It does not respond to a 301Kohm resistor

Soft brick- can be fixed using software. It's recoverable and a 301Kohm resistor will put it into download mode, even if the screen shows nothing.

A hard brick will get this or less when viewing UART output

A soft brick will get more then that.... up to this
