Installing Home Hub 5

I was installing lede using the windows instuction using tftpd and putty.

I went upto the br-lan point did the 'prepare' command without having the usb plugged in as instructed! I then plugged it in and tried the sysupgrade but this command seemed to finish too fast. I rebooted it to go to the UART and retry, but I cannot go back to the stage I was.

I cannot seem to restart and make a lan link.

I can redo the uboot and go to the VR9 point but I can't get further as it won't connect.

I've read about the tftpboot lede-lantiq-xrx200-BTHOMEHUBV5A-install-uImage-initramfs; bootm. but this wont work either.
