Hi everyone. I just picked up an R1-LTC Antrouter and am having fun playing around with it. The firmware that came stock on it is really old (based on OpenWRT Barrier_Breaker). There are newer OpenWRT trunks, even ones that support Antrouters specifically... but they only call out "R1" as the model number:

I'd love to upgrade the firmware to something newer; Barrier Breaker is so old it's a challenge to upgrade/install newer packages. Has anyone on this board tried upgrading to a newer OpenWRT -- not something downloaded straight from Bitmain?
