I am stuck trying to recover ... It enters in rescue mode putting 192.168.1.10 as ip via ethernet but with the restauration utility it does not recognice it... the power led of the router is flashing so I think is in recue mode... but maybe another segment of ips?
Some bootloader versions will use the same IP you had configured, others will use the default IP (typically 192.168.1.1). Test by pinging the IP - you should get responses with a TTL of 100.
