    Computer turned off while writing during the second cycle, now cant read or write

    So my laptop shut off while the second write cycle was processing, and now my car won't start, and I can't read or write. Tried unplugging the battery overnight and it didn't help. Also tried writing on a different computer and that didn't help either.

    Any Advice? Hoping I didn't fry my pcm

    I have a 2014 Toyota Tacoma V6 4.0 L

    It says "Detect Protocol Failed" when I try to read now, and "Controller init failed" when writing.

    Cant read any codes from an obd scanner

    Edit: ordered a new ecu, figure it is bricked since no ones responded
