Hello. Will start from the beginning. I bought a used phone Samsung Captivate. I found a problem that it doesn't connect to computers, all the PCs says an uknown device was connected. Though i have another same phone and it is ok so there is something wrong with the phone. So i decided to try to flash a new rom via CWM but there is no CWM installed on the phone so i wanted to get it installed and found out that i can't do it with Astro File Manager because my firmware is Froyo 2.2 and it doesn't support "Unknown Applications" setting. I spent around 6 hours on this problem and my head is bursting looking for the info but no luck. Please help me guys.. I don't imagine how i can move to a different ROM. Odin doesn't recognize my phone too. Regards..
