[Q] Captivate stuck in download mode

view story

http://forum.xda-developers.com – Hi everyone, I was on stock Gingerbread UCKE3. I tried installing Speedmod kernel so that I could flash Cyanogenmod 9 using this method, however it didn't work and the phone was softbricked. Which was still alright, because I could still unbrick it every time with One-Click Unbrick. So I decided to flash back to stock JF6 with Odin one-click, and it was stuck at sbl.bin for an hour. So I unplugged the phone, and it wouldn't power on anymore. Almost every, if not all, unbricking threads I've read in this forum suggested flashing back to stock ROM using the very same Odin one-click (HowTos)
