I was on Asuswrt-Merlin 3.0.0.4.266.23 and tried updating to 23b version but after pressing apply nothing happend, so I put it to rescue mode and used asus restoration firmware and after 1 minute I get an error, something about loosed connection to the router.
I tried to clear nvram with
this method or by pressing reset button and poweron router. Asus restoration firmware and device descovery didn't find my router even if I set my ip to static. Than I see the router responding to ping 192.168.1.1 and I followed this steps
here and flashed dd-wrt.v24-18702_NEWD-2_K2.6_mini_RT-N66U.trx instead of dd-wrt-v24_mini_asus.trx.
Now I can't put the router anymore in rescue mode, instead if I press wps button and poweron than all led are blinking normaly, the 2.4 and 5ghz too, at a certain moment I've seen dd-wrt in my wi-fi list but can't connect to that network, now it's not showing anymore.
Maybe has something to do with bootloader 1.0.1.3?
There is any other method to go rescue mode?
