I used the 'Summer Sale' for a Bolt+ purchase. I connected it, rolled it back to TE3, transferred some content to confirm operation and pulled the power cord. Today seeing the 4b update mentioned I powered it back up and it took the 4b as expected. I haven't added a CableCARD to this machine and likely won't soon. Right now I don't need the additional TiVo. Before pulling the 'power cord' again do I want to put this Bolt in STANDBY or just pull the plug?
