    The logicboard attached is for my Kobo Touch. Its MicroUSB port had an issue, and I couldn't charge it. So I used the four holes on the bottom-right (as seen in picture) to charge it and I was successful. I was doing this using my USB wall charger - I stripped its wires and connect Red and Black wires directly to the 1st and 3rd hole from left, respectively.

    All was good until my hand shook and one wire touched the stuff above those 4 holes while the other wire was still in the one of the holes. After that my Kobo doesn't turn on! Is the logicboard fried? How can I test if it's still alive?

    Thanks

    yes.. you have fried "something" out obviously as immediately after you shorted a wire to somewhere it shouldn't go it stopped working..

    Hehehehe yes Joey :)
    @mcgyvr: Isn't there any way to recover it? Any measure to know it is definitely fried? Thanks.

    Check the fuse but I doubt that it's the problem since they are most likely using a resetable polyfuse.You shorted the data pins which probably means that MCU or interfacing chip is dead.

    Yes.. try turning it on.. If it doesn't turn on its fried..

    Attempting to pinpoint the exact component/s that failed can be challenging even for professionals.
    Time to buy a new one
