M5300 bricked after flash erase

[somatica]

I've just received a new (to me) M5300 switch and was erasing old setings before putting new software on.

With a console cable, I interrupted the uboot process before the menu boot and ran:

=> erase all
Erase Flash Bank # 1 - Warning: 4 protected sectors will not be erased!
............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................ done
=>

Now, I get no response at all when cycling the switch, just a rapidly flashing orange power light.

Old U-boot was 

U-Boot 2011.12 (Jul 05 2012 - 05:05:25)VerNo=1.0.0.5
powerpc-wrs-linux-gnu-gcc (Wind River Linux Sourcery G++ 4.3a-274) 4.3.2
GNU ld (Wind River Linux Sourcery G++ 4.3a-274) 2.18.50.20080215

How can I restore this U-Boot/switch software to get started again please?
