Ha, not quite - I binned the original one and replaced it with another off ebay. Lasted two years before the second one also died, figured I'd try again and the serial adapter was so cheap it was worth a shot.
It does indeed look as though that error is fairly terminal - I found nothing Orbi specific, but as you say there was something on the OpenWRT forums which indicates the RBR40 isn't even getting as far as U-boot completion, and so manually updating the firmware isn't going to be an option. Time to bin this device as well...
The sad thing is, although I swore I'd never get another, it's infinitely cheaper to pick up another RBR than it is to upgrade, and if I get another 2 years out of the next one... I must be a glutton for punishment :(

Maybe go with something newer generation, AX or AXE or BE series.
IF the 40 series failing at a particular time frame, I'd move into something newer generation. I still have my 850 series from 2019. Working great.
Good Luck.
