petitboot wrong file bricked cech-g01

Think I bricked my ps3 does anyone know any way to repair this? The light comes on but will not respond to recovery menu does do the beeps however

I was installing petitboot and when you load the dtlImage file I Was downloading it directly from the ps3 to usb and I guess it downloaded bad because it was only 73 kb instead of 7mb

Now when I try to boot it just gives me a blank screen

Thanks for the replies

I have a e3 usb but it won't even read usb it seems as the light does not go on the e3
