Late yesterday night when i was too tired i fiddled around in my APU2E4 router and somehow i did something to the firewall which made me not being able to access it anymore. I can't ping 192.168.1.1 and i can't reach LuCi in the browser. I guess i might have blocked access to LAN.
Is it a serial -> USB cable that is my best bet or is there a better solution?
OpenWrt SSID/wlan is also off i guesss ?
I can see it but not connect to it
there is always factory reset
It's x86, pull the drive/mem card, or boot some dist from a flash drive, mount the rootfs, and edit the firewall settings.
Does not seem to work whatever i do with the button
This sounds like a nightmare to do without a serial cable
If the apu is set to boot from USB before going for the fixed storage, it shouldn't be.
Pulling the drive is easy enough tough.
Sorry for being dumb, but how would that help me? Even if i was able to boot from the stick, how would i connect to it? Nothing seems to work. Tried to reset, failsafe, pull the disk, use USB stick.
By browing the drive.
I don't believe it was literally said/written - so to be clear - you insert/plug/connect the drive into the running machine and then navigate to /etc/config/firewall and simply edit the file.
Additionally - to be clear, you boot a 2nd LiveUSB/LiveCD running a Linux distro in order to edit the file on the OpenWrt drive/stick.
Yes, but how would i do that without a monitor? If i could see what im doing it would be fine, but i dont. Thats why i asked if a serial cable was needed, but it would take me at least a week to get a cable like that .
Im fairly new to this so i apologize for not understanding
I'm not sure if you're getting tunnel vision, so here it is again:
This machine would [obviously] have a monitor.
I see, but then i need to find a msata to usb which doesn't seem to be the easiest thing. In that case i think the serial cable is both faster to get but also a lot cheaper.
Or msata to sata, depending on the existing hw.
For headless systems like this, you really want to have a serial cable available (I strongly recommend USB on the other side these days, as that makes it so much more flexible). Even if you'd never need it, it's still a major relief to know that it's there when/ if you need it.

USB2SATA adapters also belong into the toolbox of any IT professional or enthusiast, as they can give you quick access to a drive without opening your own (working) system.
