    I can't say I'd be of any help, but what was the error message, and have you tried flashing it again?

    I can?t remember a 100%. It would just say failed. Yes I tried it 3 times. Even with stock file. My Snapon won?t recognize vin now.

    You can restore the block by connecting directly to the block.
    To do this, you need to know where to connect the boot pin.

    You write down everything the same as with the help of K-Tag.

    I had the same thing happen to me. I ended up towing it to Toyota and they put me a new ECU in. But you should be able to send you ecu to HP Tuners and they can recover the ECU. I found that out AFTER! i gave Toyota $1800......Im still not 100% sure what I did wrong. But I still have a spare ECU now in case something happens to one.
