I recently upgraded my phone to Froyo. Shortly I decided to root my new 2.2 captivate. Everything was going fine until today. I wanted to see if I could sideload apps. So I downloaded sideload wonder machine. When i went to try to use it, my phone started acting laggy. Next, the time in the upper right corner went away. At first, I was running it on debug and my phone wasnt mounted. I mounted the phone because I had an app saved on my internal SD, so I wanted to get it from phone to pc. Thats when it started acting real sluggish. Thats when I decided to unmount it but when i did My phone stopped working completely. So i decided to turn it off. When i turned it back on it went to the att screen and the galaxy s screen. Then my phone started vibrating. Now its pulsing! it vibrates in intervals of about 10-15 seconds. After the galaxy screen the screen goes black but the bottom four keys stay lit up. and it continues to pulse. Ive tried to pull out the battery give it a min n put it back on. ive tried to get to the reboot menu but wont let me get to it. Any suggestions? Is it bricked? thanks in advance
