This stick supports dual boot: k0 and r0 contain kernel and rootfs of the first image, k1 and r1 of the second one. A full flash dump (with flash_all.xml) is available in the RTL960x repository[1]: SSH is disabled in the stock configuration and had to be enabled to make the dump.
ssh ubnt@192.168.1.1 'cat /dev/mtd0' > dev_mtd0Serial
The UART pads are, from the front (SC connector) to the back (SFP connector): GND, VCC, RX, TX[1:1]. On the RTL9601CI (76 pins) the UART is on the pins 12 (TX) and 13 (RX)[2].
Know Bugs
VLAN swap issue (MEID 171), auto-sensing mode to switch between SGMII/HiSGMII
You should use the VID/VLAN shown by executing the command omcicli mib get 84 via telnet to bring up PPPoE
The stock firmware supports only the PPTP, and only on the LAN 1: it does not support the VEIP nor the 4-port emulation[3].
