Can't boot Samsung galaxy ace GT-S5830i Failed to mount /system (Invalid argument)

I can't boot my Samsung galaxy ace GT-S5830I after I tried to flash a custom rom built for the GT-S5830, if I try and boot into Recovery I get the following errors: -- Applying Multi-CSC -- E: failed to mount /system (Invalid argument) E: failed to mount /system (Invalid argument) E: failed to mount /cache (Invalid argument) E: Can't mount /cache/recovery/log E: Can't open /cache/recovery/log E: failed to mount /cache (Invalid argument) E: Can't mount /cache/recovery/last_log E: Can't open /cache/recovery/last_log I have tried flashing using Odin and flashing again from the SD card using a different rom but that didn't work! Is there any way to fix this?
