I was trying to update to 2.2 to use the dock that I bought for her. I had problems with the the computer recognizing, then not recognizing the phone. After a bunch of tried I got it to go, the samsung kies mini uploaded the software and said it was successfull, but it would just restart with infinate loops of black --> ATT screen, and again and agian.
SO I though since it'll boot into download mode I'd go ahead and upload gingerbread to fix the issue. I followed the instructions here: http://androidadvices.com/update-samsung-galaxy-captivate-uckf1-gingerbread-233-firmware/
and it did the same thing with many attempts to connect, but finally once it connected it worked without a hitch and uploaded the firmware. Now the device won't power on. Nothing, no USB connection registers, no power button, no holding the volume up/down button. What can I do to fix my girlfriend's phone? Please help!
