What are you talking about? Transistors don't require some huge industrial base to build; the first one was made with some gold and a germanium crystal. A lot of technologies don't build on top of older technologies, they bypass them altogether. Your rebooted civilization does not need to go through a phase with fossil-fuel-burning cars to get to electric vehicles, for instance. A rebooted civilization, with stored knowledge of modern technology and enough smart people able to make use of that knowledge would be able to get back to current tech levels pretty quickly, and probably avoid most of the mistakes of the past as well.
As for useful information from the 1800s, that would mean you're losing all the modern medical knowledge, which is pretty important, and much of which does not require advanced technology to utilize. Back then, they barely even understood germs and the importance of washing hands (surgeons didn't even bother!). That alone saves tons of lives, and requires no real technology at all.
