Sorry for the delay, I actually had to use the router
As said that seemed to do the trick, unfortunately made a severe mistake with my connection (don't ask) and the firmware-partition was trashed.
I actually could connect the serial console and step 3 - method 1 actually worked as described.
finally openwrt is running here stable for more than a week, thanks for the help and the wiki entry in general!
Two more things I noticed after damaging my firmware-partition and attaching to serial console:
if I don't interrupt boot-sequence, it searches for root_uImage on 192.0.0.1/8. So I'm pretty confident that in case you damage your firmware-partition, "step 3 - method 3" would work too (using built-in TFTP recovery)
and since I used a windows-laptop for tftp-server I needed to deactivate firewall on (directly) attached LAN-cable to router to work here (interestingly step1 - method 3 worked without that trick)
Hello Leo-PL when I tried the console method I got unreadable messages in putty command line. Router type is ZTE MF286C. Also I want to know if my connection to the console is right.
R G T V so I connected T to RX, V to TX and G to GND
