To put it bluntly I wouldn't dive with electronics that lost calibration / memory. If my Shearwater did that I'd send it in.
Short of rejecting that circumstance as a possibility, what would I do if I lost electronics in a cave? SCR sounds like a good option. I could also consider doing a diluent flush add a bit of O2. Maintaining loop volume by replacing the O2 consumed gives you a reasonable PPO2 at constant depth, even if it's indirectly monitored. Deco calculations go all out the window though.
I don't consider a “lights out” electronics event a possibility because I dive with two systems that are separate and independent. Mine happen to be analog but two digital DiveCan systems are separate and independent as well.
