Totally bricked PR4100 - drive LEDs blinking red?

[Tfl]

I have added the rescue files for PR2100.
Simply put all the files (not the rescue directory) on the root a FAT formatted USB drive.

EFI              
startup.nsh    
uImage-rescue_md5checksum  
uRamdisk-rescue_md5checksum
rescue_firmware  
uImage-rescue  
uRamdisk-rescue
