Well that's a bit of a bummer…are you really really really sure the connections are all OK? Have you inspected them with a lens? Because it was working, it's likely a marginal solder connection somewhere. In my case, both signal pins of the resonator had continuity to the CAN controller, but one was 0.1 ohms and the other was something like 0.2 ohms. I'd say it's worth passing the iron over the relevant connections: the CAN bus controller, the xtal resonator, the CAN bus interface, and maybe even the main connector. Pads of the through-hole components (such as the resonator) may look OK, but it's probably worth lingering on them with the iron for a little extra heat. The good news is that there's not a whole lot to go wrong. The power supply is obviously OK, since the RN-52 is working.
