I'll take YOU's examples, which I understand (and would translate) quite differently. In the most literal sense, they spell to me as:
There's actually no focal (emphasizing) "even" in either of the sentences in Japanese. If you want to emphasize that that reading the instructions was supposed to help but didn't really help you, you can use たとえ:
