Trying to break in to the CFE on a R8000 that seems to be stuck in a boot loop (like xmas tree lights flashing).
i have done this before on different Netgear routers and also the r8000, i know you guys will reply back as i would saying it's all about timing but i feel this is different
the output only gets so far then repeats, last time i had one in boot loop i am sure it got further into the boot, putty output:

i am aware on when to ctrl +C but i've tried to get in to this now for a few days off and on to no avail.
I've not seen any response from a ping
C:\Users\foz>ping 192.168.1.1 -t
Pinging 192.168.1.1 with 32 bytes of data:
Reply from 192.168.1.10: Destination host unreachable.
repeats
Any thoughts on recovering?
Thanks for any help in advance.
unfortunately it does not reach the stage during boot to be able to TFTP firmware over. The above output in OP was read from serial connection. See my ping output, ping does not reach the bootloader ttl=100
