Unable to boot Galaxy S - only see a picture of phone -> "triangle with an exclamation point" -> computer I just bought a Galaxy S phone for my son last month.  He was trying to download Clockworkmod firmware and probably loaded the wrong version.  It initially was in a boot loop.  After I took it to the dealer, an inexperience staff tried to reset the phone back to factory mode.  The manager saw the hat logo on the phone and stopped us right there.  The manager told us that we void the warranty by downloading an authorized software.

Now, when we power up the phone, we wonly see a picture of the phone -> "triangle with an exclamation point" -> computer" .  There are no other responses.

Can anyone help.
Now, the only option you've left is to Flash your ROM. Flash any one of OFFICIAL firmware from below:  


Gingerbread 2.3.5 XFJVA   
Gingerbread 2.3.5 XXJVT


Follow the links &amp; do EXACTLY what it says. It'll take less that half an hour. Just, do it.. Nothing more! 

Don't do any experiment before you boot your device. Plus, don't follow any non-matured instructions from forums etc.
