    Checked m92t36 just to make sure, I get 3.3v output while charging on pin 5 so that chip seems to pass.

    Which pins am I needing to check on BQ24193?

    The m92t36 should be ok as it boots(sort of).

    There is a testpoint just above bq24193. What readings are you getting plugged and unplugged USB? Also... Check the 6 left-most 3 pins on bq24193(7 - 12 IIRC). They are tied together in pairs(you will only see 3 traces coming from the 6 pins).

    Plugged and unplugged voltage.

    If you have managed to restore fuel-gauge info(it MUST be done with a fully charged battery) and you are still on 0% (IMPORTANT: Showing 0mV) then almost certainly, the BQ24193 is toast.
