Default [Q] Need help restoring factory bootloader 2.3.5

I have been searching for 3 days trying to find the factory bootloader to flash to my mopho 2.3.5
can someone please help? i accidently tried to flash cwm recovery and now i cant get it back to factory bootloader. every time i try to boot into recovery it starts rsd. i have tried flashing back to factory using rsd lite and all that did was clear my root, my apps and my info but still no recovery. any help would be greatly appreciated!
