BPI-R3 Mini Firmware Flash Fail

hello everyone, i have flashed my own image on the r3 mini, but i had to realize that the lan/wan port have no function. now i unfortunately also notice that no more usb devices are recognized and therefore i cannot flash any other firmware.

the only thing that still works is serial

how can i now flash a different firmware or activate the lan ports?

ip link set eth0 up
ip link set eth1 up

etc does not work

Transfer the kmods you're missing, via serial.

How it works?

https://github.com/devttys0/serio or http://www.dannysung.com/articles/linux/tips/sending-binary-files-via-minicom/, haven't tried them myself though.

I'd probably send the lrzsz package over 1st, unless the other stuff you need is really small, and use it + a competent serial term, supporting zmodem, to transfer the rest of the packages you need.
