Have you checked your fuses...?

[Corolla05]

Yes i did all the fuses is ok

Is the car starting?

I would guess that by connecting the Battery the wrong way, you moved from a negative earth to a positive earth.

You're not the first and certainly not going to be the last to do this.

I don't know from experience but I'd imagine you have simply blow a few fuses. Remember there are several fuse boxes in a modern car, so just checking the one in the foot well often isn't a thorough check.

Did you not hear any sparks or smell burning etc?

You're likely in need of new control modules and relays etc...
