Hi there, relatively new to the scene.
I installed OpenWrt about a Year ago on an old Fritz!Box Fon Wlan 7360 i had laying around.
Now i wanted to pick it up again because i got a usecase now and i can't remember the root password. I tried Failsafe mode several times but it always asks for a password.
I know i got the mode to work because the IP i (can) connect to is 192.168.1.1 and the IP i configured for the Fritz!Box is 10.1.1.1.
My next try would be now to try reinstall OpenWrt via U-Boot but that seems so overwhelming i first wanted to ask if anyone here has something to say to my problem.
Please be friendly, this is like my first Post ever on any forum (also english is not my nativ tongue)
Already thank you <3
This means that failsafe mode isn't actually engaged.
Is there a DHCP server running when you are able to conncet to 192.168.1.1? If so, that also indicates that your device hasn't entered failsafe (in failsafe mode, there is no DHCP server running; you must set your computer via static IP).
The trick to enter failsafe mode is to repeatedly press the reset or wps button (or whatever your device has) immediately after applying power to the device until you see an LED start to flash rapidly.
The factory reset, in the sense of keeping a reset button pressed at runtime for >10s might not work, due to the physical lack of a reset button, but failsafe should working by spamming the DECT/ WPS buttons during early boot.
If everything fails, there's always the option to flash OpenWrt again, using the the bootloader's (ADAM2) ftp implementation, just like you did to originally install OpenWrt from Fritz!OS in the first place.
All indicates that failsafe works except for the fact that i got a password prompt every time (password isn't blank, it tried that)
Gonna try that now, didn't think it would work because i thought OpenWrt replaced ADAM2 with U-Boot
EDIT:
Tried it and wasn't successful. Everything worked except for getting the image over to the Fritz!Box.
I got the output of the NcFTP Client here:

Cannot open local file mtd1 for reading (errno = 2).

put mtd1: could not open file.
put mtd1: could not open file.
EDIT 2:
I also bricked it now. After the bootloader the red INFO Led is flashing. So no more failsafe mode for me i guess
EDIT 3:
IT WORKED! (sorry for screaming i'm just happy rn)
I tried some of the options in combination and what worked for me was the following:
put -z -f openwrt.image mtd1
Where z and f mean the following:
-z : Send the local file file1, and name the remote copy to file2.
-f : Force overwrite (do not try to auto-resume transfers).
I don't exactly understand why it worked like that, maybe someone of you can explain.
