"The recovery console uses a specialised modified bootloader to start up. Good news is the recovery console is still there. Bad news is you over-wrote the bootloader needed to access it.
With my r51, there was a boot-loader repair tool amongst the drivers for the model. It needed a LOT of digging to find- if there's a similar tool for your model, you should be able to gain access again for it.
This is why you always make a backup disk before you do anything major."
