Dark screen after unlocking K800

Simox...thanks for the link. Do I have to flash my phone with the same firmware version that I am on or can I use a different version (latest version). I have read some where that the main firmware and file system version must be same but i dont know if this applies to when someone wants to flash only the main firmware.

You MUST use the same Main because the Main and FS ( like you read) MUST be the same version

thank you guys for replies.....i flashed the main and fs (R8BF003) and now everything is working correctly. it appears the only solution is to flash both of them (main and fs).
