Help I am having some problems with my N900

I followed an online tuturial for trying to re-set my phone to factory default setting and now it is completley unusable.

I followed this tutorial:

now my phone wont load with an operating system. Instead I get 2 pink squares floating on a black background without any text or way to use the phone.

I have tried re-installing flasher and starting from scratch, but now every time that I copy the 2 OS and eMMc files into the flasher directory the flasher software boots and ends seconds after loading it and you can not enter commands into it.

Can someone out there please help as my phone is now unusable.
