This is not my phone but my friend's phone. I'm Captivate owner so I'm familiar with the SGS line and I've never heard of a issue like this.
This is a stock phone. No root and no custom roms. Completely stock. We tried to see if we could put the phone into download most via the key combo but no luck. He is going to bring it over later today to try the JIG which is a common thing to do for soft bricks in the Captivate forum.
Anyone else seen a problem like this and have any suggestions? Let me know. Thanks!
**UPDATE**
Now it will Randomly boot up. We tried a master reset but then it goes back into a boot loop. Then sometimes it will randomly boot but is not running well.
